Abstract: First evidence of a structure in the $J/\psi{\Lambda}$ invariant mass distribution is obtained from an amplitude analysis of$\Xi_b^-{\rightarrow}J/\psi{\Lambda}K^-$ decays. The observed structure is consistent with being due to a charmonium pentaquark with strangeness with a significance of $3.1\sigma$ including systematic uncertainties and look-elsewhere effect. Its mass and width are determined to be $4458.8\pm2.9^{+4.7}_{-1.1}$ MeV and $17.3\pm6.5^{+8.0}_{-5.7}$ MeV, respectively, where the quoted uncertainties are statistical and systematic. The structure is also consistent with being due to two resonances. In addition, the narrow excited $\Xi^-$ states, $\Xi(1690)^-$ and $\Xi(1820)^-$, are seen for the first time in a $\Xi^-_b$ decay, and their masses and widths are measured with improved precision. The analysis is performed using $pp$ collision data corresponding to a total integrated luminosity of 9 fb$^{-1}$, collected with the LHCb experiment at centre-of-mass energies of 7, 8 and 13 TeV.

Abstract: In this work, two acidic Nb P Si mixed oxide gel-derived materials characterized by Nb/P molar ratios equal to 2 (5Nb2.5P) and 1 (2.5NbP) were investigated for their surface and bulk properties in relation with the catalytic performances in the fructose dehydration reaction. The structural characteristics of the studied samples and the changes occurring after water treatment and after reaction were investigated by 29Si and 31P solid state nuclear magnetic resonance (MAS-NMR) and X-ray photoelectron (XPS) spectroscopies, while the characterization of their acidic properties was performed by base (2-phenylethylamine) adsorption in liquid phase. MAS-NMR showed that the phosphorus remains firmly anchored into the siloxane matrix after exposure to cold water for 5Nb2.5P sample and XPS confirmed the homogeneity of the sample composition. Both samples exhibited good intrinsic acidity and maintained significant effective acidity in polar-protic liquids; 2.5NbP manifested a double amount of acid sites compared to 5Nb2.5P, when 2-phenylethylamine is used as probe. Fructose dehydration to 5-(hydroxymethyl)furfural (HMF) on the two gel-derived catalysts was performed in water and in water-isopropanol solution under mild conditions (130 °C) working in a recirculation reaction line comprising a tubular catalytic reactor. In water-isopropanol solution, the samples displayed good performances, as expected thanks to the lively effective acidity. Around 45–50% fructose conversion was attained on both samples, with selectivity to HMF equal to about 50% on 2.5NbP gel-derived catalyst. Recycling tests showed satisfactorily stable activity during three consecutive runs.

Abstract: Silicon photomultipliers (SiPM) are solid state light detectors with sensitivity to single photons. Their use in high energy physics experiments, and in particular in ring imaging Cherenkov (RICH) detectors, is hindered by their poor tolerance to radiation. At room temperature the large increase in dark count rate makes single photon detection practically impossible already at 10$^{11}$ cm$^{-2}$ 1-MeV-equivalent neutron fluence. The neutron fluences foreseen by many subdetectors to be operated at the high luminosity LHC range up to 10$^{14}$ cm$^{-2}$ 1-MeV-equivalent. In this paper we present the effects of such high neutron fluences on Hamamatsu and SensL SiPMs of different cell size. The advantage of annealing at high temperature (up to 175 $^{\circ}$C) is discussed. We demonstrate that, after annealing, operation at the single photon level with a SiPM irradiated up to 10$^{14}$ cm$^{-2}$ 1-MeV-equivalent neutron fluence is possible at cryogenic temperature (77 K) with a dark count rate below 1~kHz.

Abstract: The surface and catalytic properties of oxide ternary materials consisting of niobium-phosphorus-silicon, Nb-P-Si, with Nb/P = 1 and general formula xNb2O5·xP2O5·(100–2x)·SiO2, with x = 2.5, 5, 7.5, and 10, and Si content ranging from 95 to 80 mol% are presented. Amorphous gel-derived samples were obtained, characterized by a very high degree of silicon cross-linking with presence of Si O Nb bridges, allowing phosphorus to be stably anchored to the matrix through Nb O P bonds. The morphology (surface area and porosity), the intrinsic acidity (density and average strength of the surface acid sites, by PEA-TPD in a TGA-DSC coupled instrument), and the nature of the acid sites were determined. The LAS/BAS ratio has been evaluated by FTIR of adsorbed pyridine in absence/presence of water to discover the differences between the intrinsic and effective nature of the acid sites. The amount of acid sites decreased with the Nb-content in the samples as well as the surface average acid strength. Both LAS and BAS are maintained in the presence of water, even if BAS are predominant in any case. The catalytic performances of the Nb-P-Si samples in the reaction of inulin hydrolysis were investigated in aqueous solution under mild conditions (below 100 °C).

Abstract: Hydroxyapatite loaded with different amounts of copper (from 2 to 11 wt.%, by using different Cu-precursors) was investigated as catalytic material for the NH3-SCR reaction. The method of copper addition affected the location and distribution of the copper phase in the hydroxyapatite samples as well as the aggregation state (isolated Cu2+ or CuxOy or CuO nano-aggregates). Ionic exchange procedure gave rise to Cu2+ stabilization in the exchange sites of HAP lattice, irrespective of the amount of Cu addition. Incipient wetness impregnation procedure provided samples with copper aggregation up to formation of CuO species at the highest Cu-loading. Sample characterization was performed by N2-adsorption/desorption, acidity measurement, EDX, TGA-DTGA, XRPD, UV–vis-DRS, and EPR to study the morphological and structural aspects of the copper phase. Catalytic tests of NH3-SCR revealed significant differences between the samples prepared by ionic exchange and impregnation, with activity that was dependent on the copper concentration on hydroxyapatite. Presence of 6 wt.% Cu was associated to the most active catalysts, in any case. Use of Cu-chloride and Cu-nitrate as precursors of Cu-phase, with the ionic exchange procedure, gave copper-hydroxyapatite catalysts with high activity/selectivity. Use of Cu-acetate as Cu-precursor caused some modification of the hydroxyapatite surface with enrichment of carbonate groups that were detrimental for the SCR activity.

Abstract: The decay Z→bb¯ is reconstructed in pp collision data, corresponding to 2 fb−1 of integrated luminosity, collected by the LHCb experiment at a centre-of-mass energy of s=8 TeV. The product of the Z production cross-section and the Z→bb¯ branching fraction is measured for candidates in the fiducial region defined by two particle-level b-quark jets with pseudorapidities in the range 2.2 20 GeV and dijet invariant mass in the range 45

Abstract: The observation of the decay $\varXi^{-}_{b}\to J/\psi\varLambda K^{-}$ is reported, using a data sample corresponding to an integrated luminosity of $3~\mathrm{fb}^{-1}$, collected by the LHCb detector in $pp$ collisions at centre-of-mass energies of $7$ and $8~\mathrm{TeV}$. The production rate of $\varXi_{b}^{-}$ baryons detected in the decay $\varXi_{b}^{-}\to J/\psi\varLambda K^{-}$ is measured relative to that of $\varLambda_{b}^{0}$ baryons using the decay $\varLambda_{b}^{0}\to J/\psi \varLambda$. Integrated over the $b$-baryon transverse momentum $p_{\rm T}

Abstract: The first observation of the decay ηc(2S)→pp¯ is reported using proton-proton collision data corresponding to an integrated luminosity of 3.0fb−1 recorded by the LHCb experiment at centre-of-mass energies of 7 and 8 TeV. The ηc(2S) resonance is produced in the decay B+→[cc¯]K+. The product of branching fractions normalised to that for the J/ψ intermediate state, Rηc(2S), is measured to be Rηc(2S)≡B(B+→ηc(2S)K+)×B(ηc(2S)→pp¯)B(B+→J/ψK+)×B(J/ψ→pp¯)= (1.58±0.33±0.09)×10−2, where the first uncertainty is statistical and the second systematic. No signals for the decays B+→X(3872)(→pp¯)K+ and B+→ψ(3770)(→pp¯)K+ are seen, and the 95\% confidence level upper limits on their relative branching ratios are % found to be RX(3872)

Abstract: The catalytic activity of niobium oxide-based materials, containing the same amount of Nb 2 O 5 (∼15 wt%) and prepared by different methods, with that of pure Nb 2 O 5 in the epoxidation of methyl oleate with hydrogen peroxide was compared. The catalytic performances of the catalyst prepared by impregnation do not differ substantially from the ones of Nb 2 O 5 . The performances of Nb-supported catalysts prepared by sol–gel can be modulated by controlling the process parameters. The high dispersion of the active NbO x species obtained by this preparation method gives very higher selectivity than in the case of pure Nb 2 O 5 . Morphologic and structural characterization of the catalysts helped justifying the obtained catalytic results in terms of activity and selectivity.

Abstract: The Λb0→Λc+K+K−π− decay is observed for the first time using a data sample of proton-proton collisions at centre-of-mass energies of s=7 and 8TeV collected by the LHCb detector, corresponding to an integrated luminosity of 3fb−1. The ratio of branching fractions between the Λb0→Λc+K+K−π− and the Λb0→Λc+Ds− decays is measured to be [Formula presented] where the first uncertainty is statistical, the second systematic and the third is due to the knowledge of the Ds−→K+K−π− branching fraction. No structure on the invariant mass distribution of the Λc+K+ system is found, consistent with no open-charm pentaquark signature.

Abstract: The lively acidic properties in water of niobium phosphate (NBP) catalyst and NBP modified samples by acidic treatments in HCl solutions at 0.1, 1.0, and 10 M concentration (NBP01, NBP1, and NBP10, respectively) have been exploited for the direct conversion reaction of cellobiose to hydroxymethylfurfural (HMF) at temperature of 80–130 °C. Acidity of the samples was determined by liquid-solid titrations working in a modified HPLC line with basic solutions of phenylethylamine (PEA), used as a base probe. As solvents, an apolar-aprotic one, cyclohexane, was used for determining the intrinsic acidity and water for the effective acidity. In addition, pyridine/water co-adsorption FT-IR experiments complemented the acidity study, and the results obtained confirmed the presence of both water-tolerant Lewis acid sites (LAS) and some residual Bronsted acid sites (BAS) on all the NBP samples. On NBP, the LAS to BAS ratio was 1.69, measured in cyclohexane, and only slightly decreased to 1.30, when measured in water. Catalytic activity was studied in a liquid-solid reaction line with fixed bed flow reactor working in complete recirculation. The reaction of HMF formation from cellobiose consists of three distinct catalytic actions: hydrolysis of the β-1,4-glycosidic bonds of cellobiose, isomerization of the formed glucose monomers to fructose, and cyclo-dehydration of fructose to HMF. Comparative catalytic results obtained with a sulfonic acid resin (Amberlite IR 120) showed that it was not able to form any HMF from cellobiose in the range of temperature studied, only cellobiose hydrolysis to glucose can be successfully achieved on the protonic acid resin.

Abstract: The $\Lambda_b^0\to\Lambda\phi$ decay is observed using data corresponding to an integrated luminosity of 3.0fb$^{-1}$ recorded by the LHCb experiment. The decay proceeds at leading order via a $b\to s\bar{s}s$ loop transition and is therefore sensitive to the possible presence of particles beyond the Standard Model. A first observation is reported with a significance of $5.9$ standard deviations. The value of the branching fraction is measured to be $(5.18\pm1.04\pm0.35\,^{+0.67}_{-0.62})\times10^{-6}$, where the first uncertainty is statistical, the second is systematic, and the third is related to external inputs. Triple-product asymmetries are measured to be consistent with zero.

Abstract: A search for the decays of the $B_c^+$ meson to $p\overline p\pi^+$ is performed for the first time using a data sample corresponding to an integrated luminosity of 3.0 $\mathrm{fb}^{-1}$ collected by the LHCb experiment in $pp$ collisions at centre-of-mass energies of $7$ and $8$ TeV. No signal is found and an upper limit, at 95\% confidence level, is set, $\frac{f_c}{f_u}\times\mathcal{B}(B_c^+\to p\overline p\pi^+)

Abstract: Photon detectors capable of operating in high photon rate environments are required for next generation ring imaging Cherenkov (RICH) detectors at high luminosity accelerators, like HL-LHC. These photodetectors will have to sustain single photon rate in excess of 1 GHz∕cm 2 , while being able to resist to high radiation levels of several Mrad and a 1 MeV-equivalent neutron fluence up to 10 14 n eq ∕ cm 2 . The characteristics of latest models of commercial silicon photomultipliers (SiPMs) and micro-channel plates photomultiplier tubes (MCP-PMT) are investigated in order to verify whether they satisfy the required performance, with particular emphasis on radiation hardness and high rate operation. Their innovative characteristics require tailored front-end electronics, whose architecture can be adapted to deal with higher pixel occupancy, as it will be described.

Abstract: The decay (B) over bar (0)(s) -> psi(2S)K+pi(-) is observed using a data set corresponding to an integrated luminosity of 3.0 fb(-1) collected by the LHCb experiment in pp collisions at centre-of-mass energies of 7 and 8 TeV. The branching fraction relative to the B-0 -> psi(2S)K+pi(-) decay mode is measured to be B((B) over bar (0)(s) -> psi(2S)K+pi(-))/B(B-0 -> psi(2S)K+pi(-)) = 5.38 +/- 0.36 (stat) +/- 0.22 (syst) +/- 0.31 (f(s)/f(d)) %, where f(s)/f(d) indicates the uncertainty due to the ratio of probabilities for a b quark to hadronise into a B-s(0) or B-0 meson. Using an amplitude analysis, the fraction of decays proceeding via an intermediate K*(892)(0) meson is measured to be 0.645 +/- 0.049 (stat) +/- 0.049 (syst) and its longitudinal polarisation fraction is 0.524 +/- 0.056 (stat) +/- 0.029 (syst). The relative branching fraction for this component is determined to be B((B) over bar (0)(s) -> psi(2S)K*(892)(0))/B(B-0 -> psi(2S)K*(892)(0)) = 5.58 +/- 0.57 (stat) +/- 0.40 (syst) +/- 0.32 (f(s)/f(d)) %. In addition, the mass splitting between the B-s(0) and B-0 mesons is measured as M(B-s(0)) - M(B-0) = 87.45 +/- 0.44 (stat) +/- 0.09 (syst) MeV/c(2).

Abstract: Two types of niobium-containing silica catalysts, (i) in-framework mixed oxide, obtained by co-precipitation type synthesis, and (ii) grafted niobium sites on silica supports, obtained via post-synthesis deposition from niobocene dichloride, were prepared. Both solids were tested in a series of five repeated batch-wise liquid-phase epoxidation tests of limonene with 50% aqueous hydrogen peroxide. Nb/SiO2 prepared by co-precipitation synthesis kept fully its epoxidation activity during the first two recycles, with a gradual decrease in activity in the following runs. Conversely, Nb/SiO2 prepared by deposition suffered from a more marked loss of activity since the first reuses. Most of the isolated Nb sites were maintained and no large Nb2O5 domains were formed during the recovery and regeneration tests. The distribution, geometry and coordination state of the Nb sites was therefore preserved, especially for the Nb/SiO2 sample prepared via co-precipitation. The presence of small Nb2O5 domains, even formed during repeated recycles, was not detrimental for the epoxidation reaction and, in general, Nb(V) sites inserted in a silica matrix proved to be a rather robust epoxidation catalyst for alkenes in the presence of aqueous hydrogen peroxide.

Abstract: The Electronics system of experiments for the study of rare decays, such as the neutrino-less double beta decay, must be very stable over very long expected runs. We introduce our solution for the power supply of such an experiment, CUORE. In this case the power supply chain consists of a series of ACDCs, followed by DCDCs and then Linear Regulators. We emphasize here our approach to the DCDC regulation system that was designed with a complete rejection of the switching noise, across 100 MHz bandwidth. In the experimental layout the DCDC will be located far from the very front-end, with long connecting cables (10 m). We introduced our very simple and safe solution to prevent huge over-voltages, due to the energy stored in the inductance of the cables, generated after the release of accidental short circuits, so avoiding destructive effects. Some micro-controllers are present on every board and take care of the DCDC operation. These micro-controllers are managed from the control room, via CAN BUS protocol coupled via optical fibres. CUORE is an array of 1000 cryogenic detectors that will need 30 of our DCDCs.

Abstract: A search for time-integrated CP violation in the Cabibbo-suppressed decay D-0 -> pi(+)pi(-)pi(+)pi(-) is performed using an unbinned, model-independent technique known as the energy test. This is the first application of the energy test in four-body decays. The search is performed for P-even CP asymmetries and, for the first time, is extended to probe the P-odd case. Using proton proton collision data corresponding to an integrated luminosity of 3.0 fb(-1) collected by the LHCb detector at centre-of-mass energies of root s = 7 TeV and 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 (4.6 +/- 0.5)% in the P-even case, and marginally consistent with a p-value of (0.6 +/- 0.2)% in the P-odd case, corresponding to a significance for CP non -conservation of 2.7 standard deviations.

Abstract: Decays of B s 0 and B ‾ 0 s mesons into J / ψ π + 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 ϕ s = − 0.057 ± 0.060 ± 0.011 rad, the decay-width difference between the heavier mass B s 0 eigenstate and the B 0 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 ϕ s = 0.002 ± 0.044 ± 0.012 rad, and | λ | = 0.949 ± 0.036 ± 0.019 .

Abstract: Acidity modulation of the niobic acid surface, Nb2O5·nH2O (NBO), by ion doping was pursued with the aim to limit the deactivation observed in fructose dehydration reaction performed in water due to insoluble humin formation and deposition on the NBO surface. Three series of K-, Ba-, and Nd-doped NBO catalysts prepared with different ion loading (from 1 to 15 atom nm−2) have been characterized and tested in the fructose dehydration reaction. Catalyst effective acidity, measured in water by 2-phenyl-ethylamine (PEA) adsorption, was in relation to the catalyst activity, with a clear effect on the fructose conversion. The long-term catalyst stability (up to 200 h of reaction time) was studied in a flow reactor with fixed catalytic bed at constant temperature of 100 °C by controlling activity, and in particular, selectivity to 5-hydroxymethylfurfural (HMF). The kinetic rate constants of deactivation were obtained; they have been associated with a faster (0.004 < kdeact,1/h−1 < 0.058) and a slower (0.001 < kdeact,2/h−1 < 0.005) deactivation phenomenon. Comparison among the samples in terms of activity and effective acidity, measured in water, in long term reaction is here presented.

Abstract: The $B_s^0\to J/\psi K_S^0$ branching fraction is measured in a data sample corresponding to 0.41$fb^{-1}$ of integrated luminosity collected with the LHCb detector at the LHC. This channel is sensitive to the penguin contributions affecting the sin2$\beta$ measurement from $B^0\to J/\psi K_S^0$ The time-integrated branching fraction is measured to be $BF(B_s^0\to J/\psi K_S^0)=(1.83\pm0.28)\times10^{-5}$. This is the most precise measurement to date.

Abstract: The catalytic dehydration of fructose (FRU) to 5-hydroxymethylfurfural (HMF) usually runs with the formation of several side products. Among these, levulinic acid (LA) is often reported as the product of a consecutive reaction of HMF re-hydration. In this work, side reactions of the dehydration of FRU performed in very green conditions (water as solvent and niobic acid as solid catalyst) are taken into account. Experimental evidences are given that, in the used conditions: i) HMF is a final stable product, ii) no formation of LA, either deriving from a consecutive reaction of HMF or directly from FRU transformation, was observed, and iii) LA does not react to give condensation products with any other chemical species present in the reaction mixture.

Abstract: By dispersing a niobia phase in/on silica matrix it was possible to maintain the catalytic activity in the dehydration of fructose in water for longer time without any deactivation, compared with the fast deactivation observed on bulk niobium oxide hydrate. The surface acidity of the bulk niobium oxide hydrate and silica-diluted niobia materials was responsible of the different catalytic performances observed. As the dehydration reaction can run in water, in agreement with the development of a green process, the acid properties of the catalysts were comparatively studied in water too, to find sound relations between acid and catalytic properties. On all the catalysts, the effective acidity, determined in water, was much lower compared with the intrinsic acidity determined in cyclohexane, as expected. A relation between the catalytic activity in the dehydration of fructose and the amount of effective acid sites of the samples was evidenced.

Abstract: The dispersion, acidity, reducibility and adsorption capacities of nanostructured, atomic layer deposited (ALD) V 2 O 5 /TiO 2 /SiO 2 catalysts were examined by BET, XRD, FTIR and Raman spectroscopy, XPS, H 2 -TPR and microcalorimetry. TiO 2 -supported and standard liquid-phase impregnated catalysts were characterized for comparison, and the influence of the catalyst properties on their performance was probed in a test reaction of o-xylene selective oxidation. Gas-phase deposited, isolated vanadia species were highly dispersed independently of the support nature, whereas crystalline vanadia was detected in the impregnated catalysts with submonolayer coverage of titania. Likewise, the reducibility of the ALD catalysts was enhanced in relation to the corresponding impregnated catalysts. The activity of the ALD and impregnated catalyst increased with the decrease in number of strong surface Lewis acid and o-xylene adsorption sites. o-Xylene conversion was greater on the highly dispersed ALD catalysts on TiO 2 , and on TiO 2 /SiO 2 supports with high titania content, than on their impregnated counterparts.

Abstract: The degradation of polypropylene in the presence of solid catalysts of different acidity was studied by thermogravimetric analysis (TGA) employing three different heating rates. The temperatures of onset, Ton, of maximum-rate, Tmax, as well as of end, Tend, of the degradation shifted to lower values as higher the acidity of the catalysts. A comparison among the catalytic activities has been performed on the basis of the apparent kinetic parameters, frequency factor and activation energy, obtained from the TG data. The maximum activity was observed for the more acidic catalysts (silica-aluminas).

Abstract: The hydrotreatment of a petroleum residue in the presence of dispersed molybdenite was carried out within a wide range of operating conditions and catalyst loading. The effect of reaction severity as well as of molybdenum concentration on product distribution and quality was studied. Based on the experimental results, a simplified reaction scheme was proposed. The hydroprocessing of the residue was described in terms of the competition between two reactions: the direct conversion of the feedstock to distillate and coke, and the catalytic hydrogenation. Compared to thermal conditions, the presence of dispersed molybdenite controls very well coke formation; however, a trend of increasing formation of solids was observed at high catalyst concentrations. The overall upgrading of the feedstock requires significant amounts of molybdenum as well as relatively high hydrogen pressure.

Abstract: Catalytic selective reduction of NO to N 2 was studied comparing a series of Cu-based catalysts (ca. 8 wt.%) supported over amorphous pure and modified silicas: SiO 2 , SiO 2 -Al 2 O 3 , SiO 2 -TiO 2 , SiO 2 -ZrO 2 . The catalysts were prepared by the chemisorption-hydrolysis method which ensured the formation of a unique copper phase well dispersed over all supports, as confirmed by scanning electron micrographs (SEMs). Temperature-programmed reduction (TPR) analyses confirmed the presence of dispersed copper species which underwent complete reduction at a temperature of about 220°C, independently of the support. It was found that the support affects the extent of NO reduction as well as the selectivity to N 2 formation. Maximum N 2 yield was found in the range 275–300°C. The catalyst prepared over SiO 2 -Al 2 O 3 was the most active and selective with respect to the other silicas. Competitiveness factors (c.f.’s) as high as 13–20% in the temperature range 200–250°C could be calculated. For all catalysts, the temperature of the N 2 peak maximum did not correspond to that of the maximum C 2 H 4 oxidation to CO 2 , suggesting the presence of two different sites for the oxidation and the reduction activity. On the catalyst prepared on SiO 2 -Al 2 O 3 , a kinetic interpretation of catalytic data collected at different contact times and temperatures permitted evaluating the ratio between kinetic coefficients as well as the difference between activation energies of NO reduction by C 2 H 4 and C 2 H 4 oxidation by O 2 .

Abstract: The CLARO-CMOS is a prototype ASIC that allows fast photon counting with low power consumption, built in AMS 0.35 μm CMOS technology. It is intended to be used as a front-end readout for the upgraded LHCb RICH detectors. In this environment, assuming 10 years of operation at the nominal luminosity expected after the upgrade, the ASIC must withstand a total fluence of about 6×10 12 1 MeV n eq /cm 2 and a total ionising dose of 400 krad. Long term stability of the electronics front-end is essential and the effects of radiation damage on the CLARO-CMOS performance must be carefully studied. This paper describes results of multi-step irradiation tests with protons up to the dose of ~8 Mrad, including measurement of single event effects during irradiation and chip performance evaluation before and after each irradiation step.

Abstract: The catalytic degradation of polystyrene, carried out in sealed tubes with solid catalysts having different acidic properties (i.e. silica-magnesia, silica-titania, mordenite and two silica-aluminas), was studied. Reaction temperatures in the range 360–420 °C for reaction times up to 30 min were investigated. The reaction was followed by ESR analysis through a direct quantitative determination of radicals. The kinetic parameters of the initiation step of the multi-step process of polystyrene degradation were obtained, through a computer optimization routine applied to the experimental data. The results are compared with those obtained for the pure thermal reaction.

Abstract: Two source rocks containing type II kerogen, both from Italy, were studied to evaluate the formation of radicals during thermal treatment. Crushed and extracted rocks were pyrolysed in sealed tubes at different times and temperatures in the range 350–500°C. The pyrolysed samples were spectroscopically analyzed by ESR and the formed radicals were quantitatively determined. The experimental data were kinetically interpreted. The kinetic coefficients and the parameters obtained were compared with those of the reaction generating hydrocarbons. The maximum amount of radicals formed in the laboratory experiments was in a good agreement with the maximum concentration of radicals observed in kerogens of different natural maturation.

Abstract: The catalytic degradation of polystyrene, carried out in sealed tubes with different acidic catalysts (i.e., silica, zeolites, and silica-aluminas), was studied. Two reaction temperatures, 350 and 400°C, for reaction times up to 120 min were investigated. The reaction was followed both by electron spin resonance and gas chromatography-mass spectrometric analysis. The different distributions of volatile products (C6–C24) obtained in the various cases are discussed, arranging the products into groups. An initiation mechanism, involving the formation of radical cations, is proposed for the degradation of polystyrene on strongly acidic catalysts.

Abstract: Wheat straw was pretreated by steam explosion under various conditions. The capability of the process in inducing a high fractionation of the lignocellulosic material in its major components and the influence of the explosion conditions on the substrate susceptibility to the attack of cellulolytic enzymes have been investigated. Bioconversion was studied considering the cellulose-rich fraction obtained from product fractionation as well as the product directly obtained from the explosion treatment. Quantitative data in terms of rate and yield of hydrolysis have been obtained for the different conditions.

Abstract: Several hydrous pyrolysis kinetic runs have been carried out on a source rock sample from Northern Italy (type II kerogen) under isothermal conditions in the range 260–330°C and at 15–17 MPa in an argon atmosphere. The products have been quantified and grouped into four classes: light (gas + volatile liquids), saturate, aromatic, and heavy (asphaltenes + resins). The distribution of these classes as well as the bulk composition of the overall product was found to be fairly constant during the whole reaction course, suggesting that primary cracking prevails in the temperature range explored. The kinetic results have been interpreted regarding the degradation as the result of numerous simultaneous independent first-order reactions. The number, the relative importance and the Arrhenius parameters for such reactions have been evaluated using an optimization procedure. The best fitting of the experimental data was achieved considering three simultaneous reactions.

More than 80% of the products in the distillate from the catalytic reactions at T≥350°C comprised eleven main compounds, in contrast to thermal degradation which gave essentially styrene and dimer. This different product distribution, which was obtained by GC-MS analysis, gave helpful indications about the mechanism of degradation.

Kinetic parameters corresponding to different positions of enzymic attack were determined and product inhibition was evaluated. The enzymic hydrolysis was compared in terms of reaction rate and pattern of action with hydrolysis in 0.1 m H 2 SO 4 at 70°. Mathematical models for the mechanism of hydrolysis were developed and a good rationalisation of the experimental results was achieved.

Abstract: Toluene disproportionation was performed at 300°–360°C in a fixed-bad reactor (carrier H 2 ) over samples of HZSM-5 differing in surface acidity, organic compound used for the synthesis, crystal size and procedure used for decationation. Xylene isomers in the product were in equilibrium ratios. The catalyst activity was found to be clearly dependent on surface acidity. An interpretation is given, in terms of a slow toluene disproportionation within the zeolite pores, followed by fast xylene isomerization on the external surface. Measurements of the reaction rate at 300°C over one of the catalysts confirmed a kinetic model as previously suggested.

Abstract: The rate of phenol degradation by activated sludge was studied in a completely mixed continuous-flow reactor with sludge recycle, operated at steady-state conditions at 20°C. Monod kinetics was followed when the influent concentration ( C s °) was kept constant. When using different C s ° levels, the phenol removal rate was found to have an inverse dependence on C s °. It is suggested that this kinetic anomaly is due to inhibition of the biooxidation by some secondary reaction product(s). A kinetic model based on this concept is able to interpret experimental facts.

Abstract: Carniti, P., Cori, L. and Ragaini, V., 1978. A Critical Analysis of the Hand and Othmer-Tobias Correlations. Fluid Phase Equilibria, 2: 39–47. The Hand (H) and Othmer-Tobias (OT) correlations are extensively analyzed on 83 aqueous and 26 non-aqueous ternary systems. Twenty solutropic systems are also included. 65% and 58% of the systems give a linear correlation coefficient greater than 0.99 for H and OT respectively. An analysis of the sensitivity to systematic or random errors demonstrates the H correlation to be highly insensitive. A remarkable insensitivity, although not completly for some systematic errors, is also demonstrated for the OT correlation. However there is sufficient proof that they are both unsuitable as a check of experimental data, even though they are used for this purpose. The relation, not necessarily linear, derived from the H correlation, log(x32/x22) vs. log(x31/x11) is useful in locating the plait point.

Abstract: Toluene disproportionation in the gas/solid phase was performed in a flow reactor (carrier H 2 or N 2 ) over some partially exchanged X and Y zeolites and, more systematically, over decationated Y, ZSM-5 and ZSM-11 zeolites. Activity, selectivity and stability of the catalysts were tested at temperatures up to 500°C, but mostly in the range 350°–400°C. Two samples HZSM-5 showed a considerably different catalytic behaviour: with one of them, shape-selectivity effects, favouring p -xylene, were observed during progressive deactivation (carrier N 2 ); the other one, of higher and stable activity, gave xylenes in the equilibrium isomeric ratios. Using the latter zeolite, kinetic measurements were carried out in a differential reactor at 240°–300°C (carrier H 2 ). A few kinetic models were tested.

Abstract: Monosubstituted phenols ( meta or para substituents: MeO, C1, CN, NO2) were used as inhibitors of the phenol degradation by an activated sludge. By kinetic measurements, the inhibiting action was expressed as pI50, and the latter quantity was correlated with structural properties (logP, σ) of the inhibitors. The QSAR referring to the present system is compared with previous correlations based on different sludges and different sets of inhibitors, showing that the largely predominant factor of phenolic inhibition can be the phenol's lipophilicity.

A carefully adapted sludge was able to degrade DCP, besides the accompanying substrate, with no evidence of substrate inhibition in the concentration range covered (156 mg l−1 in the influent). The reactivity order was found to be glucose ⪢ phenol > DCP. The results of a series of kinetic runs with phenol + DCP were interpreted by a first-order equation for phenol and by the Monod model for DCP.

Abstract: Kinetic measurements on the degradation of phenol in a batch reactor were done at 20°C using an activated sludge taken from a continuous reactor where the process had shown Monod-type kinetics without substrate inhibition. When employing a sludge sample, adapted to the substrate steady concentration C s 1 , for runs with initial substrate concentration C s 0 , observed batch rates were as high as expected for C s 0 = C s 1 , but lower than expected in runs carried out at C s 0 > C s 1 1 , with indications of a transient inhibitory effect instead of a positive response to the increased substrate concentration. It is concluded that kinetic data collected in a batch reactor are of limited value for the design of a continuous biodegradation process.

The QSARs referring to the present activated sludge are compared with previous correlations of data obtained with a different sludge.
