Abstract: According to the survey, wild purslane (Portulaca oleracea L.) has two different ecotypes, one with the red stem living in an arid environment and one with the green stem living in a humid environment. In order to explore the physiological response strategies of plants to environmental changes, these two ecotypes of purslane were selected as experimental materials. Physiological indices were determined and transcriptome analysis was carried out to screen the differentially expressed genes (DEGs) from two ecotypes of purslane. The results showed that the content of soluble sugars, proline, anthocyanins, and chlorophylls was significantly different, and most DEGs belonged to the WRKY and NAC families. Finally, the results of transcriptome analysis were verified by real-time qPCR. Therefore, it can be inferred that the transcription factor (TF) families may play an important role in physiological response strategies by regulating the changes of anthocyanins and osmotic regulators (soluble sugars, proline, etc.) through the abscisic acid signalling pathway. This will accelerate the study of purslane at the molecular level, provide corresponding theoretical support for its artificial domestication, and drought breeding.

2. Simultaneous strength-ductility enhancement in as-cast Ti6Al4V alloy by trace Ce

Abstract: Impurity elements always play a major role in hindering mechanical property improvement in Ti6Al4V, and specifically most of them e.g. O, P, Cl, and S dissolved in the matrix deteriorate the mechanical properties of Ti6Al4V. This work presents a strategy of enhancing the mechanical performance of as-cast Ti6Al4V alloy by adding a small amount of rare earth (i.e. 0.1 wt% Ce), where deleterious elements could be absorbed from the crystalline lattice during solidification process, forming uniformly distributed Ce-rich oxides or precipitates with ∼200 nm in size. The Ce-rich precipitates in turn refine the beta phase lamellae by introducing more nucleation in the cast alloy, which further enhances the strength. As such, the cast Ti6Al4V with Ce addition exhibits a tensile strength of 957 ± 47 MPa and elongation of 12.3%, which exhibits a simultaneous strength-ductility enhancement compared with the Ti6Al4V counterpart (787 ± 65 MPa and 8.8%). In addition, the Ce-rich precipitates also pin dislocation motions, which effectively shields the stress concentration at the crack tip and deflects the crack propagation during fracture process.

Abstract: A search for CP violation in Λb0→pK− and Λb0→pπ− decays is presented using a sample of pp collisions collected with the LHCb detector and corresponding to an integrated luminosity of 3.0fb−1. The CP -violating asymmetries are measured to be ACPpK−=−0.020±0.013±0.019 and ACPpπ−=−0.035±0.017±0.020, and their difference ACPpK−−ACPpπ−=0.014±0.022±0.010, where the first uncertainties are statistical and the second systematic. These are the most precise measurements of such asymmetries to date.

Abstract: Decays of Bs0 and B‾0s mesons into J/ψπ+π− final states are studied in a data sample corresponding to 1.9 fb−1 of integrated luminosity collected with the LHCb detector in 13 TeV pp collisions. A time-dependent amplitude analysis is used to determine the final-state resonance contributions, the CP-violating phase ϕs=−0.057±0.060±0.011 rad, the decay-width difference between the heavier mass Bs0 eigenstate and the B0 meson of −0.050±0.004±0.004 ps−1, and the CP-violating parameter |λ|=1.01−0.06+0.08±0.03, where the first uncertainty is statistical and the second systematic. These results are combined with previous LHCb measurements in the same decay channel using 7 TeV and 8 TeV pp collisions obtaining ϕs=0.002±0.044±0.012 rad, and |λ|=0.949±0.036±0.019.

5. Intercalation process in the preparation of 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide-montmorillonite nanocompounds and their application in epoxy resins

Abstract: To enhance the flame retardancy of epoxy resins (EPs), 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) and montmorillonite (MMT) nanocompounds were prepared. In their preparation, anhydrous, pristine and watery calcium-based montmorillonite (CaMMT) and sodium-based montmorillonite (NaMMT) were used through molten DOPO, a DOPO solution in ethanol, and ball milling. The intercalation processes of DOPO into MMT were studied. It was found that water and ethanol molecules were disadvantageous to the intercalation. In the anhydrous state, DOPO could intercalate faster into NaMMT than CaMMT. It was observed that the DOPO-CaMMT nanocompounds could induce good intercalated and exfoliated dispersion in EPs by transmission and scanning electron microscopy. The flame retardancy, glass transition and mechanical properties of the EPs were investigated by limiting oxygen index (LOI), UL-94 vertical burning test, cone calorimetry, differential scanning calorimetry (DSC), dynamic mechanical analysis (DMA) and three-point bend testing. The DOPO-CaMMT nanocompounds ensured that the EP composites exhibited good performance due to the good dispersion of the CaMMT layers in the matrix.

Abstract: Enterotoxigenic Escherichia coli (ETEC) is a type of pathogenic bacteria that cause diarrhea in piglets through colonizing pig small intestine epithelial cells by their surface fimbriae. Different fimbriae type of ETEC including F4, F18, K99 and F41 have been isolated from diarrheal pigs. In this study, we performed a genome-wide association study to map the loci associated with the susceptibility of pigs to ETEC F41 using 39454 single nucleotide polymorphisms (SNPs) in 667 F2 pigs from a White Duroc×Erhualian F2 cross. The most significant SNP (ALGA0022658, P=5.59×10−13) located at 6.95 Mb on chromosome 4. ALGA0022658 was in high linkage disequilibrium (r2>0.5) with surrounding SNPs that span a 1.21 Mb interval. Within this 1.21 Mb region, we investigated ZFAT as a positional candidate gene. We re-sequenced cDNA of ZFAT in four pigs with different susceptibility phenotypes, and identified seven coding variants. We genotyped these seven variants in 287 unrelated pigs from 15 diverse breeds that were measured with ETEC F41 susceptibility phenotype. Five variants showed nominal significant association (P

Abstract: A search for the rare decays Bs0→π+π−μ+μ− and B0→π+π−μ+μ− is performed in a data set corresponding to an integrated luminosity of 3.0 fb−1 collected by the LHCb detector in proton–proton collisions at centre-of-mass energies of 7 and 8 TeV. Decay candidates with pion pairs that have invariant mass in the range 0.5–1.3 GeV/c2 and with muon pairs that do not originate from a resonance are considered. The first observation of the decay Bs0→π+π−μ+μ− and the first evidence of the decay B0→π+π−μ+μ− are obtained and the branching fractions, restricted to the dipion-mass range considered, are measured to be B(Bs0→π+π−μ+μ−)=(8.6±1.5 (stat)±0.7 (syst)±0.7(norm))×10−8 and B(B0→π+π−μ+μ−)=(2.11±0.51(stat)±0.15(syst)±0.16(norm))×10−8, where the third uncertainty is due to the branching fraction of the decay B0→J/ψ(→μ+μ−)K⁎(892)0(→K+π−), used as a normalisation.

Abstract: Time-dependent CP violation is measured in the B0→J/ψπ+π− channel for each π+π− resonant final state using data collected with an integrated luminosity of 3.0 fb−1 in pp collisions using the LHCb detector. The final state with the largest rate, J/ψρ0(770), is used to measure the CP-violating angle 2βeff to be (41.7±9.6−6.3+2.8)°. This result can be used to limit the size of penguin amplitude contributions to CP violation measurements in, for example, Bs0→J/ψϕ decays. Assuming approximate SU(3) flavour symmetry and neglecting higher order diagrams, the shift in the CP-violating phase ϕs is limited to be within the interval [−1.05°,+1.18°] at 95% confidence level. Changes to the limit due to SU(3) symmetry breaking effects are also discussed.

Abstract: The difference in total widths between the Bc+ and B+ mesons is measured using a data sample corresponding to an integrated luminosity of 3.0 fb−1 collected by the LHCb experiment in 7 and 8 TeV centre-of-mass energy proton–proton collisions at the LHC. Through the study of the time evolution of Bc+→J/ψπ+ and B+→J/ψK+ decays, the width difference is measured to beΔΓ≡ΓBc+−ΓB+=4.46±0.14±0.07 mm−1c, where the first uncertainty is statistical and the second systematic. The known lifetime of the B+ meson is used to convert this to a precise measurement of the Bc+ lifetime,τBc+=513.4±11.0±5.7 fs, where the first uncertainty is statistical and the second is systematic.

Abstract: Using the latest LHCb measurements of time-dependent CP violation in the Bs0→K+K− decay, a U-spin relation between the decay amplitudes of Bs0→K+K− and B0→π+π− decay processes allows constraints to be placed on the angle γ of the unitarity triangle and on the Bs0 mixing phase −2βs. Results from an extended approach, which uses additional inputs on B0→π0π0 and B+→π+π0 decays from other experiments and exploits isospin symmetry, are also presented. The dependence of the results on the maximum allowed amount of U-spin breaking is studied. At 68% probability, the value γ=(63.5−6.7+7.2)° modulo 180° is determined. In an alternative analysis, the value −2βs=−0.12−0.16+0.14 rad is found. In both measurements, the uncertainties due to U-spin breaking effects up to 50% are included.

Using proton–proton collision data, corresponding to an integrated luminosity of 2.0 fb−1 collected by the LHCb detector at a centre-of-mass energy of s=8 TeV, the world's best sensitivity to CP violation in this decay is obtained. The data are found to be consistent with the hypothesis of CP symmetry with a p-value of (2.6±0.5)%.

Abstract: The B¯0–B0 and B¯s0–Bs0 production asymmetries, AP(B0) and AP(Bs0), are measured by means of a time-dependent analysis of B0→J/ψK⁎0, B0→D−π+ and Bs0→Ds−π+ decays, using a data sample corresponding to an integrated luminosity of 1.0 fb−1, collected by LHCb in pp collisions at a centre-of-mass energy of 7 TeV. The measurements are performed as a function of transverse momentum and pseudorapidity of the B0 and Bs0 mesons within the LHCb acceptance. The production asymmetries, integrated over pT and η in the range 4

Abstract: A model-dependent amplitude analysis of B±→DK± with D→KS0π+π− decays is performed using proton–proton collision data, corresponding to an integrated luminosity of 1 fb−1, recorded by LHCb at a centre-of-mass energy of 7 TeV in 2011. Values of the CP violation observables x± and y±, which are sensitive to the CKM angle γ, are measured to be x−=+0.027±0.044−0.008+0.010±0.001, y−=+0.013±0.048−0.007+0.009±0.003, x+=−0.084±0.045±0.009±0.005, y+=−0.032±0.048−0.009+0.010±0.008, where the first uncertainty is statistical, the second systematic and the third arises from the uncertainty of the D→KS0π+π− amplitude model. The value of γ is determined to be (84−42+49)°, including all sources of uncertainty. Neutral D meson mixing is found to have negligible effect.

Abstract: Measurements of the effective lifetimes in the Bs0→K+K−, B0→K+π− and Bs0→π+K− decays are presented using 1.0 fb−1 of pp collision data collected at a centre-of-mass energy of 7 TeV by the LHCb experiment. The analysis uses a data-driven approach to correct for the decay time acceptance. The measured effective lifetimes are τBs0→K+K−=1.407±0.016(stat)±0.007(syst) ps, τB0→K+π−=1.524±0.011(stat)±0.004(syst) ps, τBs0→π+K−=1.60±0.06(stat)±0.01(syst) ps. This is the most precise determination to date of the effective lifetime in the Bs0→K+K− decay and provides constraints on contributions from physics beyond the Standard Model to the Bs0 mixing phase and the width difference ΔΓs.

Abstract: Using a data sample of pp collisions corresponding to an integrated luminosity of 3 fb−1, the Ξb− and Ωb− baryons are reconstructed in the Ξb−→J/ψΞ− and Ωb−→J/ψΩ− decay modes and their lifetimes measured to be τ(Ξb−)=1.55−0.09+0.10 (stat)±0.03 (syst) ps,τ(Ωb−)=1.54−0.21+0.26 (stat)±0.05 (syst) ps. These are the most precise determinations to date. Both measurements are in good agreement with previous experimental results and with theoretical predictions.

Abstract: The mixing-induced CP-violating phase ϕs in Bs0 and B¯s0 decays is measured using the J/ψπ+π− final state in data, taken from 3 fb−1 of integrated luminosity, collected with the LHCb detector in 7 and 8 TeV centre-of-mass pp collisions at the LHC. A time-dependent flavour-tagged amplitude analysis, allowing for direct CP violation, yields a value for the phase ϕs=70±68±8 mrad. This result is consistent with the Standard Model expectation and previous measurements.

Abstract: Evidence for the decay mode X(3872)→ψ(2S)γ in B+→X(3872)K+ decays is found with a significance of 4.4 standard deviations. The analysis is based on a data sample of proton–proton collisions, corresponding to an integrated luminosity of 3 fb−1, collected with the LHCb detector, at centre-of-mass energies of 7 and 8 TeV. The ratio of the branching fraction of the X(3872)→ψ(2S)γ decay to that of the X(3872)→J/ψγ decay is measured to be B(X(3872)→ψ(2S)γ)B(X(3872)→J/ψγ)=2.46±0.64±0.29, where the first uncertainty is statistical and the second is systematic. The measured value does not support a pure DD¯⁎ molecular interpretation of the X(3872) state.

Abstract: According to the survey, wild purslane (Portulaca oleracea L.) has two different ecotypes, one with the red stem living in an arid environment and one with the green stem living in a humid environment. In order to explore the physiological response strategies of plants to environmental changes, these two ecotypes of purslane were selected as experimental materials. Physiological indices were determined and transcriptome analysis was carried out to screen the differentially expressed genes (DEGs) from two ecotypes of purslane. The results showed that the content of soluble sugars, proline, anthocyanins, and chlorophylls was significantly different, and most DEGs belonged to the WRKY and NAC families. Finally, the results of transcriptome analysis were verified by real-time qPCR. Therefore, it can be inferred that the transcription factor (TF) families may play an important role in physiological response strategies by regulating the changes of anthocyanins and osmotic regulators (soluble sugars, proline, etc.) through the abscisic acid signalling pathway. This will accelerate the study of purslane at the molecular level, provide corresponding theoretical support for its artificial domestication, and drought breeding.

Abstract: Fast radio bursts (FRBs) are short pulses observed in radio band from cosmological distances, some of which emit repeating bursts. The physical origins of these mysterious events have been subject to wide speculations and heated debates. One class of models invoke soft gamma-ray repeaters (SGRs), or magnetars, as the sources of FRBs. Magnetars are rotating neutron stars with extremely strong magnetic field and can sporadically emit bursts from X-ray (keV) to soft gamma-ray (sub-MeV) with duration from 10􀀀2 s to 102 s. However, even though some bright radio bursts have been observed from some magnetars, no FRB-like events had been detected to be associated with any magnetar burst, including one giant flare, and no radio burst has been associated with any X-ray event from any magnetar. Therefore, there is still no observational evidence for magnetar-FRB association up to today. Recently, a pair of FRB-like bursts (FRB~200428 hereafter) separated by 30 milliseconds (ms) were detected from the general direction of the Galactic magnetar SGR~J1935+2154. Here we report the detection of a non-thermal X-ray burst in the 1--250\,keV energy band with the Insight-HXMT satellite, which we identify as emitted from SGR~J1935+2154. The burst showed two hard peaks with a separation of ms, consistent with the separation between the two bursts in FRB~200428. The delay time between the double radio and X-ray peaks is 8:57s, fully consistent with the dispersion delay of FRB~200428. We thus identify the non-thermal X-ray burst is associated with FRB~200428 whose high energy counterpart is the two hard peaks in X-ray. Our results suggest that the non-thermal X-ray burst and FRB~200428 share the same physical origin in an explosive event from SGR~J1935+2154.

Abstract: We use the In data collected during the 2019 outburst from X-ray pulsar 4U 1901+03 to complement the orbital parameters reported by Fermi/GBM. Using the Insight-HXMT, we examine the correlation between the derivative of the intrinsic spin frequency and bolometric flux based on accretion torque models. It was found that the pulse profiles significantly evolve during the outburst. The existence of two types of the profile's pattern discovered in the Insight-HXMT data indicates that this source experienced transition between a super-critical and a sub-critical accretion regime during its 2019 outburst. Based on the evolution of the pulse profiles and the torque model, we derive the distance to 4U 1901+03 as 12.4+-0.2 kpc., 8 pages, 5 figures, accepted by JHEAP

Abstract: Thin ZK61 magnesium alloy sheets with ultrafine–grain structure were fabricated by cumulative cold rolling with intermediate annealing treatments. Microstructure refinement and uniformity were manifestly achieved by multiple static recrystallization during the process while planar texture anisotropy was strikingly improved as {0002} basal pole intensity in transverse direction gradually enhanced and that in rolling direction weakened. The dispersed precipitates mainly composed of blocky β 1 ′ (Mg2Zn3 or Mg4Zn7) and globular β equilibrium phases slightly aggregated and coarsened as the process continuing. The two aforementioned factors of grain refinement and texture variation resulted in a contrary tendency in yield strength with grain size between rolling direction and transverse direction in coarse grain region but an identical increment afterwards under stable basal texture, which was well estimated following the Hall–Petch relationship with texture effect. Fracture elongation over 25% was obtained due to the enhancement of basal texture weakening to uniform elongation following e u ≈78.8 m bas. and that of grain refining to post–uniform elongation accounting for 40%.

We report a new measurement from a campaign between {\sl Insight}-HXMT and {\sl NuSTAR} performed in February 2018. Generally, the two satellites show well consistent results of timing and spectral properties. The joint spectral analysis confirms that the previously observed long decay phase has ended, and that the line energy instead keeps constant around 37.5 keV after flux correction.

Abstract: Discovering functional applications of metallic glasses (MGs) as heterogeneous catalysts is a fundamental and essential topic. This work reports the rapid production of sulfate radicals (SO4·−) from peroxymonosulfate (PMS) using Fe73.5Si13.5B9Cu1Nb3 glassy ribbons as catalysts for Eosin Y (EY) dye wastewater treatment. The reaction rates (k) from the experimental data reveal that the EY degradation is well fitted with the pseudo-first-order kinetic model. The strong electron transfer ability is characterized by electrochemical methods, presenting an advanced catalytic performance for EY degradation. Various experimental parameters, including dye concentration, catalyst dosage, PMS concentration, light intensity, pH and reaction temperature as well as the saline and natural inorganic effects, are fully investigated. The results show that the color removal of EY dye could achieve nearly 100% within 20 min. The quenching experiments are performed to verify the production of reactive species, suggesting that both ·OH and SO4·− are produced from PMS and play significant roles in EY degradation. This critical study reveals that using Fe73.5Si13.5B9Cu1Nb3 MGs as catalysts exhibits a superior reactivity on PMS activation in wastewater treatment. The discoveries shed lights into the study of electron transfer ability for MGs, presenting extensive prospects in the application of dye wastewater treatment.

Abstract: Three combined-extrusion techniques of second extrusion, die upsetting and extrusion, and cyclic extrusion and compression were used to fabricate three typical {0002} basal textures of fiber texture, dispersed texture and inclined texture, respectively, in the fine-grained ZK61 magnesium alloy. The tension-compression asymmetries were compared and the texture influence on asymmetry mechanical response was well evaluated using a Semianalytical Sachs model that followed Schmid law and highlighted the importance of slip/twining activity in tension-compression asymmetry. It was found that in strong fiber-textured materials, solely refining grains could not obviously improve the tension-compression asymmetry. However, basal texture dispersed/inclined was conducive to activation of basal slip in tension and impeding of twining in compression, leading to gentler strain hardening and low tension-compression asymmetry. The uniaxial symmetry managed to be kept in cyclic loading under low strain amplitude, with the cyclic maximum stresses in accordance with uniaxial yield values. Symmetric high-strength ZK61 magnesium alloys with tensile and compressive yield stresses (1.0 % offset) over 300 MPa were achieved by basal texture dispersion feasibly controlled by die upsetting extrusion technique.

Abstract: The cold drawing of magnesium wires has constantly been an obstacle in industrial manufacture due to the lack of sufficient independent slip system at ambient temperature and the frequent intermediate annealing gives rise to regrettably low production efficiency. Aiming at the technique challenge, a feasible and effective method of multi-pass cumulative cold drawing with small deformation per pass was utilized in this study and a wire of 0.625 mm in diameter was obtained out of primitive Φ2.0 mm material with the accomplishment of about 2.3 in cumulative strain (90% in area reduction), the efficiency of which was dramatically improved. The microstructure, texture and mechanical properties with the variation of cumulative area reduction were investigated. It can be apparently observed that continuous dynamic recrystallization had occurred during cold drawing. The outcomes are displayed as follows: the transition emerged from low angle grain boundary to high angle grain boundary; the increased fraction of undeformed/recrystallized structure first descended then ascended; the deformed structure initially appeared yet disappeared quickly. All of above owned an almost same critical point at around 23% cumulative area reduction. One of the most remarkable consequences of the deformation was the degeneration of the average grain size steadily from 11.8 to 3.1 µm. 〈10-10〉//DD fiber component was gradually transformed from the primitive {0002}//DD fiber texture and this deformation texture was continuously strengthened. The enhanced mechanical properties achieved uncommonly high strength of 214.5 MPa in yield strength and 256.9 MPa in ultimate tensile strength due to grain refinement arising from continuous dynamic recrystallization and intense fiber texture strengthening introduced during cold drawing.

Abstract: Upsetting-extrusion (UE) process effectively prepared high-strength ZK61 magnesium alloy rods with tension/compression symmetry. The influence of upsetting-extrusion temperature and upsetting ratio on microstructure was studied. Microstructure evolution in the UE process included two stages: {10–12} tensile twinning significantly divided and refined the coarse grains in upsetting stage, forming a //ED (extrusion direction) texture component; grain refinement suppressed the inverse occurrence of {10–12} tensile twinning during extrusion stage, promoting multi-slip deformation and dynamic recrystallization (DRX) and leading to the diffused {0001}//ED texture. Lowering temperature and increasing upsetting ratio played positive roles in twinning division and DRX refinement. Both of them were beneficial to basal texture weakening which could effectively inhibit the activation of tensile twinning during compression, and promote basal slip contribution during tension, thus improving tension/compression asymmetry. The relationship between microstructure and tension/compression yield strengths was analyzed by texture-dependent Hall-Petch relationship composed of slip and twinning deformation mechanisms. Only slight weakening of the extruded fiber texture was required for tension/compression symmetry for fine-grained structure; but it was the opposite for coarse-grained structure. Correspondingly, only smaller critical upsetting ratio was needed at lower upsetting temperature.

Abstract: TiO 2 particles with desirable properties were produced by undergoing specific durations of ball milling. Characterizations of the TiO 2 particles before and after ball milling were investigated via X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), particle size analysis, zeta potential, and scanning electron microscope (SEM). The equilibrium adsorption data were well fitted to Langmuir, Freundlich, and Dubinin-Radushkevich (D-R) isotherms. Compared to the as-received TiO 2 (mean particle size d 50 = 0.78 μm, specific surface area = 88.17 m 2 g −1 , pore volume = 0.41 cm 3 g −1 ), the 60 min ball-milled TiO 2 ( d 50 = 0.55 μm, specific surface area = 99.48 m 2 g −1 , pore volume = 0.48 cm 3 g −1 ) enhanced the adsorption quantity of congo red and methylene blue from 10.4 mg g −1 to 13.6 mg g −1 , and from 17.0 mg g −1 to 22.2 mg g −1 , respectively; and also improved the kinetic rates from k = 0.1325 to 0.2193, and k = 0.0944 to 0.1553, respectively. Dye adsorption and degradation efficiency of congo red was enhanced in acidic pH range (2–5.14), and methylene blue was enhanced in alkaline pH range (7.58–12).

Abstract: In this paper, Ti-22Al-25Nb alloy bars were successfully prepared by elemental powder metallurgy and subsequent hot extrusion (1200 °C, extrusion ratio of 10.56:1). The microstructure characterization, texture and mechanical property have been systematically investigated. Results showed that DRX occurred prior near grain boundary and further refined the B2 grains during the hot extrusion process. Besides, the as-extruded microstructure consists of both DRX grains and elongated grains, in addition, the as-extruded Ti-22Al-25Nb alloy exhibited strong (110)B2//ED. Meanwhile, {001} and {111} fiber textures were also introduced due to dynamic recrystallization. The good combination of tensile strength (1122.7 MPa) and elongation (7.9%) have been obtained in the as-extruded Ti-22Al-25Nb alloys at room temperature. Besides, the as-extruded alloy also exhibited super-high tensile strength at elevated temperatures (close to 916.5 MPa at 650 °C and 613.1 MPa at 800 °C). The enhanced properties can be attributed to the comprehensive effects including deformation textures, grain refinement and dissolution of bulks α2 phase.

Abstract: Two novel, multifunctional Fe-based amorphous alloys with the nominal components of Fe78Si9B13 and Fe73.5Si13.5B9Cu1Nb3 exhibit advanced catalytic capability when degrading methyl blue (MB) and methyl orange (MO) dyes. The production rate of hydroxyl radicals ( OH) in this work is 5–10 times faster than other Fe-based catalysts. The surface aging behaviour on Fe78Si9B13 and Fe73.5Si13.5B9Cu1Nb3 ribbons shows a significant effect on the dye degradation efficiency and reusability of the catalyst. Results reveal that crystallized α-Fe, iron oxide and SiO2 are gradually precipitated on the surface of the reused Fe78Si9B13 ribbon which ultimately becomes corroded through with holes. However, the inclusion of Nb atoms in the Fe73.5Si13.5B9Cu1Nb3 alloy causes the formation of niobium oxides which overlay the ribbon surface, and tend to reduce the contact area between the Fe and H2O2, thereby decreasing the generation of OH and further reducing the dye degradation efficiency. Tert-butanol is employed for quenching hydroxyl radicals ( OH), causing a dramatic reduction in the amount available for degrading the MB and MO molecules. The MB and MO dye degradation and mineralization under UV–vis light are also fully investigated. The findings of this critically important work should form the basis of new research opportunities into the study of amorphous alloy catalysis.

Abstract: The development of new functional applications of amorphous alloy is an active and challenging topic. In this work, amorphous Fe78Si9B13 alloy, a photo-enhanced Fenton-like catalyst, exhibits excellent functional ability in degrading an azo dye. This study reports the dramatic performance gains achieved for photo-enhanced Fenton-like degradation of cibacron brilliant red 3B-A (BR3B-A) dye aqueous solutions, the reusability of amorphous Fe78Si9B13 alloy ribbon catalysts, and the reaction kinetics (k) of the process. The individual and synthetical effects of the various reaction parameters are investigated by employing an orthogonal matrix (L16(45)) experimental methodology. The investigation evaluates the impact of these parameters on the degradation process, in order to demonstrate that UV–vis light could continuously induce hydroxyl radicals ( OH) to be generated in the dye aqueous solution and significantly enhance the rate of dye degradation and mineralization. The experimental results show that nearly 100% color removal is achieved within 5 min under conditions of 2.0 g/L Fe78Si9B13 ribbons, 0.5 M H2O2 and pH 2. UV–vis light intensity ranging from 0 to 7.7 μW/cm2 enhances a dramatic improvement in color removal from 78% at 200 min to 98% at 60 min and an improvement in the reaction kinetics (k) from 0.0413 at 0 μW/cm2 of light irradiation to 0.2901 at 7.7 μW/cm2 of light irradiation under conditions of 2.0 g/L Fe78Si9B13 ribbons, 0.5 M H2O2 and natural pH 6.45. The production of OH is investigated by adding tertiary butanol, resulting in a sharp decrease of dye color removal. Structural characterizations of as-received amorphous Fe78Si9B13 ribbons and of recycled Fe78Si9B13 ribbons are also investigated by transmission electron microscopy (TEM), X-ray diffraction (XRD), UV–vis diffuse reflectance spectrophotometers (UV–vis DRS), scanning electron microscope (SEM) and energy-dispersive X-ray spectroscopy (EDS); the results reveal a slight decay of the reused Fe78Si9B13 ribbons, along with a gradual precipitation of crystallized α-Fe, iron oxide and SiO2 on the ribbon surface over the few cycles of usage.

Abstract: Sm2Zr2O7 and (Sm2/3Yb1/3)2Zr2O7 feedstocks prepared by spray drying have been used to produce ceramic thermal barrier coatings. Double-ceramic-layer thermal barrier coatings with an under-layer of 8 wt.% yttria-stabilized zirconia (YSZ) and a top-layer of Sm2Zr2O7 or (Sm2/3Yb1/3)2Zr2O7 were deposited by plasma spraying. Plasma sprayed Sm2Zr2O7 coatings are composed of a pyrochlore-type phase and a t-ZrO2 phase, while (Sm2/3Yb1/3)2Zr2O7 coatings exhibit a defect fluorite-type structure. The number of thermal shock failure at 1250 °C is 52 and 33 for Sm2Zr2O7/YSZ and (Sm2/3Yb1/3)2Zr2O7/YSZ coatings, respectively. The thermal shock failure of zirconates/YSZ double-ceramic-layer coatings mainly occurs inside ceramic layers, and is not caused by the thermal grown oxide layer from the bond coat.

Abstract: The microstructure and mechanical properties of Mg–6.63wt.%Zn–0.56wt.%Zr (ZK61) Mg alloy sheets processed by temperature–step–down multi–pass rolling were investigated. A uniform fine–grained structure with the average grain size of about 3.5 μm, which is enriched with rod–shaped β 1 ′ (MgZn2) and blocky β 1 ′ (Mg2Zn3) precipitates, is attained by multiple dynamical recrystallization. An intense {0002} basal texture with a–axis randomly rotated in the plane is developed. As a consequence, a yield strength of 219 MPa, an ultimate tensile strength of 313 MPa, and a fracture elongation larger than 32% can be obtained. This enhancement in strength during rolling is mainly due to grain refinement and basal texture strengthening in the early stage, and is further contributed by precipitation hardening, simultaneously. Ductility improvement is attributed to the enhanced uniform elongation correlated with twinning suppression, and the enhanced post–necking elongation controlled by grain refinement, especially at the fine grain sizes. This can provide an essential reference for designing high-performance wrought Mg alloy sheets suitable for industrial fabrication.

Abstract: Cold-drawn AZ31 Mg alloy wires with a wide range of strains up to ~1.2 were prepared by multi-pass cold drawing to investigate the influence of cold strain on microstructural evolution. With the drawing, plastic deformation was initially dominated by twinning, particularly {10–10} twinning, but gradually becoming by slips especially after twinning was exhausted at large strains>1. More importantly, pronounced refined crystallites with diameter ~100 nm were achieved through profuse intersections across twin bundles starting from strains larger than ~0.6, and contributed to the weakening of {0002} fiber texture. This refinement could be interpreted as twin fragmentation related to dynamic recovery; and to some extent it implied a possibility of fabrication of ultrafine-grained structure by cold severe plastic deformation for magnesium alloys.

Abstract: The (B) over bar (0)-B-0 and (B) over bar (0)(s)-B-s(0) production asymmetries, A(P)(B-0) and A(P)(B-s(0)), are measured by means of a time-dependent analysis of B-0 -> J/Psi K-*0, B-0 -> D-pi(+) and B-s(0) -> D-s(-)pi(+) decays, using a data sample corresponding to an integrated luminosity of 1.0 fb(-1), collected by LHCb in pp collisions at a centre-of-mass energy of 7 TeV. The measurements are performed as a function of transverse momentum and pseudorapidity of the B-0 and B-s(0) mesons within the LHCb acceptance. The production asymmetries, integrated over p(T) and eta in the range 4 < p(T) < 30 GeV/c and 2.5 < eta < 4.5, are determined to be A(P)(B-0) = (-0.35 +/- 0.76 +/- 0.28)% and A(P)(B-s(0)) = (1.09 +/- 2.61 +/- 0.66)%, where the first uncertainties are statistical and the second systematic.

Abstract: Pyrochlore-type (La0.8Eu0.2)2Zr2O7 feedstocks prepared by spray drying have been used to produce ceramic thermal barrier coatings. Double-ceramic-layer thermal barrier coatings with a first layer of 8 wt% yttria-stabilized zirconia (YSZ) and a top layer of (La0.8Eu0.2)2Zr2O7 were deposited by plasma spraying. Plasma sprayed (La0.8Eu0.2)2Zr2O7 coatings are composed of a defect fluorite-type phase and a t-ZrO2 phase. However, after thermal shock tests at 1250 °C for 32 cycles, (La0.8Eu0.2)2Zr2O7 coatings exhibit a pyrochlore-type structure. The thermal shock failure of double-ceramic-layer (La0.8Eu0.2)2Zr2O7/YSZ coatings mainly occurs at the interface between the (La0.8Eu0.2)2Zr2O7 and YSZ layers, and is not caused by thermal grown oxide layer from the bond coat.

Abstract: Two novel laminated Ti–TiBw/Ti composites, consisting of pure Ti layers with different thicknesses of 200 μm and 400 μm and TiB whisker reinforced Ti (TiBw/Ti) composite layers with a constant thickness of 200 μm, were successfully fabricated by diffusion welding. Herein, the individual thickness of the two layers can be controlled accurately through raw Ti sheets and TiBw/Ti composite sheets. The two prepared laminated composites exhibit higher ultimate tensile strength (625 MPa and 569 MPa, respectively) and higher elongations (19.0% and 27.5%, respectively) compared with pure Ti material (546 MPa, 17.5%). The superior ductility is mainly attributed to the necking delaying effect and delamination shielding effect. Fracture characteristics show that many tunnel cracks were formed in TiBw/Ti composite layer and shear bands were presented in the pure Ti layer. Moreover, interfacial delamination was formed between Ti layer and TiBw/Ti composite layer interface, which is beneficial to toughen the laminated composites.

Abstract: The LHCb measurement of the lifetime ratio of the Lambda(0)(b) baryon to the (B) over bar (0) meson is updated using data corresponding to an integrated luminosity of 3.0 fb(-1) collected using 7 and 8 TeV centre-of-mass energy pp collisions at the LHC. The decay modes used are Lambda(0)(b) -> J/psi pK(-) and (B) over bar (0) -> J/psi pi K-+(-), where the pi K-+(-) mass is consistent with that of the (K) over bar*(0)(892) meson. The lifetime ratio is determined with unprecedented precision to be 0.974 +/- 0.006 +/- 0.004, where the first uncertainty is statistical and the second systematic. This result is in agreement with original theoretical predictions based on the heavy quark expansion. Using the current world average of the (B) over bar (0) lifetime, the Lambda(0)(b) lifetime is found to be 1.479 +/- 0.009 +/- 0.010 ps. (C) 2014 The Authors. Published by Elsevier B.V.

Abstract: The CP-violating charge asymmetry in B-+/- -> phi K-+/- decays is measured in a sample of pp collisions at 7 TeV centre-of-mass energy, corresponding to an integrated luminosity of 1.0 fb-1 collected by the LHCb experiment. The result is A(CP)(B-+/- -> phi K-+/-) = 0.022 +/- 0.021 +/- 0.009, where the first uncertainty is statistical and the second systematic. In addition, a search for the B-+/- -> phi pi(+/-) decay mode is performed, using the B-+/- -> phi K-+/- decay rate for normalization. An upper limit on the branching fraction B(B-+/- -> phi pi(+/-)) < 1.5 x 10(-7) is set at 90% confidence level. (C) 2013 The Authors. Published by Elsevier B.V. All rights reserved.

Abstract: The differential branching fraction of the decay Λ0b→Λμ+μ− is measured as a function of the square of the dimuon invariant mass, q2. A yield of 78 ± 12 Λ0b →Λμ+μ− decays is observed using data, corresponding to an integrated luminosity of 1.0 fb−1, collected by the LHCb experiment at a centre-of-mass energy of 7 TeV. A signiﬁcant signal is found in the q2 region above the square of the J/ψ mass, while at lower-q2 values upper limits are set on the differential branching fraction. Integrating the differential branching fraction over q2, while excluding the J/ψ and ψ(2S) regions, gives a branching fraction of B(Λ0b→Λμ+μ−)=(0.96±0.16(stat)±0.13(syst)±0.21(norm))×10−6, where the uncertainties are statistical, systematic and due to the normalisation mode, Λ0b → J/ψΛ, respectively.

Abstract: First evidence of the $B^0\to J/\psi\omega$ decay is found and the $B_{s}^0\to J/\psi\eta$ and $B_{s}^0\to J/\psi\eta^{\prime}$ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 $\mathrm{fb}^{-1}$ collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of $\sqrt{s} = 7$ TeV. The branching fractions of these decays are measured relative to that of the $\mathrm{B}^0\to J/\psi\rho^0$ decay: $$\frac{Br(B^0\to J/\psi\omega)}{Br(B^0\to J/\psi\rho^0)} = 0.89 \pm0.19(stat)^{+0.07}_{-0.13}(syst)$$ $$\frac{Br(B^0_s\to J/\psi\eta)}{Br(B^0\to J/\psi\rho^0)} = 14.0 \pm 1.2(stat)^{+1.1}_{-1.5}(syst)^{+1.1}_{-1.0}(\frac{f_d}{f_s}),$$ $$\frac{Br(B^0_s\to J/\psi\eta^{\prime})}{Br(B^0\to J/\psi\rho^0)} = 12.7\pm1.1(stat)^{+0.5}_{-1.3}(syst)^{+1.0}_{-0.9}(\frac{f_d}{f_s}),$$ where the last uncertainty is due to the knowledge of $f_d/f_s$, the ratio of b-quark hadronization factors that accounts for the different production rate of $B^0$ and $B^0_s$ mesons. The ratio of the branching fractions of $B^0_s\to J/\psi\eta^{\prime}$ and $B^0_s\to J/\psi\eta$ decays is measured to be $$ \frac{Br(B^0_s\to J/\psi\eta^{\prime})}{Br(B^0_s\to J/\psi\eta)} = 0.90\pm0.09(stat)^{+0.06}_{-0.02}(syst).$$

Abstract: A binned Dalitz plot analysis of $B^\pm \to D K^\pm$ decays, with $D \to K^0_{\rm S} \pi^+\pi^-$ and $D \to K^0_{\rm S} K^+ K^-$, is performed to measure the CP-violating observables $x_{\pm}$ and $y_{\pm}$ which are sensitive to the CKM angle $\gamma$. The analysis exploits 1.0 $\rm fb^{-1}$ of data collected by the LHCb experiment. The study makes no model-based assumption on the variation of the strong phase of the D decay amplitude over the Dalitz plot, but uses measurements of this quantity from CLEO-c as input. The values of the parameters are found to be $x_- = (0.0 \pm 4.3 \pm 1.5 \pm 0.6) \times 10^{-2}$, $y_- = (2.7 \pm 5.2 \pm 0.8 \pm 2.3) \times 10^{-2}$, $x_+ = (-10.3 \pm 4.5 \pm 1.8 \pm 1.4)\times 10^{-2}$ and $y_+ = (-0.9 \pm 3.7 \pm 0.8 \pm 3.0)\times 10^{-2}$. The first, second, and third uncertainties are the statistical, the experimental systematic, and the error associated with the precision of the strong-phase parameters measured at CLEO-c, respectively. These results correspond to $\gamma = (44^{\,+43}_{\,-38})^\circ$, with a second solution at $\gamma \to \gamma + 180^\circ$, and $r_B = 0.07 \pm 0.04$, where $r_B$ is the ratio between the suppressed and favoured B decay amplitudes.

Abstract: Measurement of the mixing-induced CP-violating phase ϕs in decays is of prime importance in probing new physics. Here 7421±105 signal events from the dominantly CP-odd final state J/ψπ+π− are selected in 1 fb−1 of pp collision data collected at with the LHCb detector. A time-dependent fit to the data yields a value of , consistent with the Standard Model expectation. No evidence of direct CP violation is found.

Abstract: An approach of calibration method for 3D sensing scheme based on shifted point array encoding is presented. Initially a 3D calibration benchmark is established in object space, the camera subsystem can be calibrated with the benchmark. The projection optics subsystem is bounded with camera subsystem in this sensing scheme so a constraint condition is imposed on both subsystems. Therefore it is possible to calibrated projection subsystem by introducing a concept of benchmark transmission. Once both subsystems have been calibrated, the 3D coordinates of range image can be obtained with moderate accuracy. The coordinate difference between measured data and prescribed benchmark is used to define a square-error based objective function, leading to a non-linear equation. By solving this equation, one is able to determine the required parameters of the system configuration. Experiment results show that, after proposed calibration procedure, the 3-D sensing scheme based on point array encoding is able to achieve such an accuracy as the standard deviation in X direction is 0.29mm, 0.24mm in Y direction, and 0.29mm in Z direction, respectively, for a measuring volume of 300×300×80mm3.

Abstract: The first observation of the Cabibbo-suppressed decay $\Lambda_b^0\rightarrow J/\psi p \pi^-$ is reported using a data sample of proton-proton collisions at 7 and 8 TeV, corresponding to an integrated luminosity of 3 $\rm fb^{-1}$. A prominent signal is observed and the branching fraction relative to the decay mode $\Lambda_b^0\rightarrow J/\psi p K^-$ is determined to be $$ \frac{{\cal B}(\Lambda_b^0\rightarrow J/\psi p \pi^-)}{{\cal B}(\Lambda_b^0\rightarrow J/\psi p K^-)}=0.0824\pm0.0025\:(\text{stat})\pm0.0042\:(\text{syst}). $$ A search for direct CP violation is performed. The difference in the CP asymmetries between these two decays is found to be $$ {\cal A}_{CP}(\Lambda_b^0\rightarrow J/\psi p \pi^-)-{\cal A}_{CP}(\Lambda_b^0\rightarrow J/\psi p K^-)=(+5.7\pm 2.4\:(\text{stat})\pm1.2\:(\text{syst}))\%, $$ which is compatible with CP symmetry at the $2.2\sigma$ level.

Abstract: Production of ϒ $$ \varUpsilon $$ mesons in proton-lead collisions at a nucleon-nucleon centre-of-mass energy s NN $$ \sqrt{s_{NN}} $$ = 5 TeV is studied with the LHCb detector. The analysis is based on a data sample corresponding to an integrated luminosity of 1 . 6 nb −1 . The ϒ $$ \varUpsilon $$ mesons of transverse momenta up to 15 GeV/ c are reconstructed in the dimuon decay mode. The rapidity coverage in the centre-of-mass system is 1 . 5 < y < 4 . 0 (forward region) and −5 . 0 < y < −2 . 5 (backward region). The forward-backward production ratio and the nuclear modification factor for ϒ $$ \varUpsilon $$ (1 S ) mesons are determined. The data are compatible with the predictions for a suppression of ϒ $$ \varUpsilon $$ (1 S ) production with respect to proton-proton collisions in the forward region, and an enhancement in the backward region. The suppression is found to be smaller than in the case of prompt J/ψ mesons.
