This study used electrochemical corrosion, intergranular corrosion (IGC), and exfoliation corrosion tests, as well as microscopic observations of the microstructure and first-principles calculations, to investigate the effect of different quenching rates on the microstructure and corrosion properties of the 7199 alloy. The results show that as the quenching rate decreases, the size, Zn, and Mg content of precipitated phases at grain boundaries (GBs), as well as the width of the precipitation-free zone (PFZ), increase, resulting in a decrease in corrosion properties. During slow quenching, the η phase (MgZn2) at the GBs continuously absorbs surrounding Zn and Mg atoms, causing Zn and Mg atom depletion near the GBs. This results in the formation of a wide PFZ. Enlargement of the η phase and PFZ at the GBs leads to anodic dissolution channels, allowing for rapid corrosion expansion along the GBs. Additionally, at slow quenching rates, not only does the η phase precipitate at the subgrain boundaries (SGBs) but also the T and S phases. In corrosive environments, the η phase is more prone to corrosion than the T and S phases. Electron work function calculations show that the S phase has the highest corrosion potential, whereas the η phase has the lowest. As a result, SGBs containing T and S phases are unlikely to serve as corrosion pathways. Corrosion preferentially extends along SGBs containing η phases.

This work investigates the influence of erbium (Er) content on the microstructure, mechanical properties, and corrosion behavior of T6 state AA6061 sheets. The findings reveal that nanoscale Al(Fe, Mn)Si particles are the main factors hindering dislocation motion and grain boundaries (GBs) migration. The addition of an appropriate amount of Er (0.6 wt%) effectively inhibits the precipitation of nanoscale Al(Fe, Mn)Si particles, promoting dislocation motion and grain boundary migration, thus significantly enhancing the alloy's plasticity. Furthermore, the sufficient migration of GBs leads to an increase in grain size, significantly reducing the quantity of GBs. This reduces the path for the propagation of corrosion cracks, resulting in improved corrosion resistance. Simultaneously, the addition of an appropriate amount of Er refines the coarse iron-rich phases into short rod-shaped Er-containing iron-rich phases with lower height and potential. This enables the alloy to obtain a more uniform oxide film and significantly reduces the tendency for microgalvanic corrosion, which is conducive to slowing down the initiation of corrosion. However, excessive Er addition (0.8–1.4 wt%) lead to the extensive precipitation of Er-containing iron-rich phases and nanoscale Al(Fe, Mn)Si particles, along with a continuous increase in the number of GBs, adversely affecting the plasticity and corrosion resistance of the alloy. This work offers a new strategy for obtaining 6XXX series alloys with excellent plasticity and corrosion resistance.

Molecular metal compounds have demonstrated excellent catalytic activity and product selectivity in the H2evolution reaction (HER) and the CO2reduction reaction (CO2RR). The heterogenization of molecular catalysts is regarded as an effective approach to improve their applicability. In this work, the molecular catalytic units [Cp*Ir(Bpy)Cl]+and [Ru(Bpy)(CO)2Cl2] are constructed in situ on the bipyridine sites of the covalent organic framework for photocatalytic HER and CO2RR, respectively. Inheriting the impressive performance of molecular catalysts, the functionalized TpBpy–M exhibits excellent catalytic activity and product selectivity. Under visible light irradiation, the H2production rate of TpBpy–Ir is about 760 μmol g–1h–1, which is 6.7 times higher than that of TpBpy without built-in catalytic sites. Also, the HCOOH production rate of TpBpy–Ru is 271 μmol g–1h–1, with an impressive selectivity of 88%. Control experiments validated that this improvement is attributed to the incorporation of molecular catalytic units into the framework. Photoluminescence spectroscopy measurements and theoretical calculation consistently demonstrate that, under illumination, the photosensitizer [Ru(Bpy)3]Cl2is excited and transfers electrons to the catalytic sites in TpBpy–M, which then catalyzes the reduction of H+and CO2.

In recent years, the utilization of medical devices has gradually increased and implantation procedures have become common treatments. However, patients are susceptible to the risk of implant infections. This study utilized chemical grafting to immobilize polyethylenimine (QPEI) and hyaluronic acid (HA) on the surface of the mesh to improve biocompatibility while being able to achieve antifouling antimicrobial effects. From the in vitrotesting, PP–PDA-Q-HA exhibited a high antibacterial ratio of 93% against S. aureus, 93% against E. coli, and 85% against C. albicans. In addition, after five rounds of antimicrobial testing, the coating continued to exhibit excellent antimicrobial properties; PP–PDA-Q-HA also inhibits the formation of bacterial biofilms. In addition, PP–PDA-Q-HA has good hemocompatibility and cytocompatibility. In vivostudies in animal implantation infection models also demonstrated the excellent antimicrobial properties of PP–PDA-Q-HA. Our study provides a promising strategy for the development of antimicrobial surface medical materials with excellent biocompatibility.

Hot tensile features of a commercial 7046 aluminum alloy are investigated through employing high-temperature tensile tests. The evolving mechanisms of microstructures over high-temperature tensile parameters are systematically revealed. A unified dislocation-density related constitutive model is proposed to reconstruct hot tensile stress–strain behaviors. Results imply that the microstructural evolving features are acutely influenced by tensile parameters. The principal softening mechanism converts from dynamic recovery (DRV) to dynamic recrystallization (DRX), as the tensile temperature reaches 350 °C or above. The combined DRX nucleation features containing discontinuous DRX (DDRX) as well as continuous DRX (CDRX) together emerge. Furthermore, the CDRX behavior characterized by substructural nucleation and interaction becomes apparent at low tensile temperature or high strain rate, while the DDRX process is weaken. Through validation, the reproduced tensile stress, grain size as well as DRX fraction are good accordance with experimented values, which proves the proposed dislocation-density related equation can enjoy an outstanding reproduced capacity for the thermal tensile features of a 7046 aluminum alloy.

In this study, the room temperature thermal conductivities and microstructures of Al-Si binary alloys in as-cast, low-temperature annealing state and solid solution state are investigated. The experimental results show that annealing treatment increases the thermal conductivities of these alloys because of the decreasing Si concentration in α-Al matrix, which is determined by EPMA. The effect of solution treatment on the thermal conductivity of Al-xSi (0 ≤ x≤ 12) alloys can be divided into two stages. When the Si content is less than 3 wt%, the thermal conductivities of solution treated specimens are lower than that of as-cast, which is mainly attributed to the increase in Si concentration. However, solution treatment improves the thermal conductivities of Al-xSi (x> 3) alloys owing to the spheroidization of Si phase. Quantitative study is conducted on the effect of Si element on thermal conductivity of as-cast Al-xSi alloys. The thermal conductivities of Al-xSi alloys are fitted using modified Series and Maxwell models based on the Si concentration in α-Al matrix, distribution and volume fractions of Si phases. The modified structural models provide a better fit to the measured thermal conductivity data.

We anchored Ph–CC–Cu, a type of metal organic molecule, onto the surface of α-Bi2O3nanoparticles (NPs) to efficiently eliminate a high concentration of methyl orange (MO) in waste water. With the optimal α-Bi2O3/Ph–CC–Cu hybrid, the degradable concentration of MO was 3 × 10−4M, which is 5 times higher than that in most of the previously reported photocatalytic researches (6 × 10−5M). The photocatalytic activity of the α-Bi2O3/Ph–CC–Cu hybrid in this work even exceeds that of commercial P25 for MO degradation under full spectrum light. Furthermore, a targeted Z-scheme construction was proposed and demonstrated using photocatalytically generated reactive oxygen species (ROS), photocurrent densities, fluorescence spectra and photocatalytic reduction of AgNO3experiment. This work not only reported an efficient hybrid for MO elimination with high concentration in waste water, but also provided new explanations for the Z-scheme mechanism.

Great attention has been focused on the design of good thermal conductivity and high-strength Al–Si alloys to ensure the dissipation of heat and load of electronic components. In this study, the Al–7Si alloy was modified by various content additions of Sr, B, RE and Sb elements. The results show that these modifiers can significantly improve the thermal conductivity and electrical conductivity of Al–7Si alloys to varying degrees. Among them, the 0.05 wt% Sr-modified Al–7Si alloy achieves the highest thermal conductivity (169.6 W/m K) and electrical conductivity (24.27 MS/m). The higher conductivity is due to the systematic optimization of eutectic Si. Sr-modified Al–7Si alloy can change the size, distribution of the eutectic Si phase and transform them from coarse plate-shaped to a fine short slab-shaped or coral-shaped. By these means, it will increase the number and mean free paths of heat transfer electrons, thereby improving the thermal conductivity of Al–7Si alloy.

Electrocatalytic N2reduction to NH3under ambient conditions is an eco-friendly and sustainable alternative to the traditional Haber-Bosch process. However, inhibited by the high activation barrier of N2, this process needs efficient electrocatalysts to adsorb and activate the N2, enabling the N2reduction reaction (NRR). Herein, we report that porous LaFeO3nanofiber with oxygen vacancies acts as an efficient NRR electrocatalyst with abundant active sites to enhance the adsorption and activation of N2. When tested in 0.1 M HCl, such electrocatalyst achieves a high Faradaic efficiency of 8.77% and a large NH3yield rate of 18.59 µg h–1mgcat.–1at −0.55 V versus reversible hydrogen electrode. This catalyst also shows high long-term electrochemical stability and excellent selectivity for NH3formation. Density functional theory calculations reveal that, by introducing oxygen vacancy on LaFeO3, the subsurface metallic ions are exposed with newly localized electronic states near the Fermi level, which facilitates the adsorption and activation of N2molecules as well as the subsequent hydrogenation reactions.

The synthetic dinickel complex [Ni(phma)(μ-S,S')Ni(dppp)] not only possess the principal feature of [NiFe]-H2ases, but also reappear their fascinating catalytic abilities for H2-evolution.

Nickel oxide (NiOx) has exhibited great potential as an inorganic hole transport layer (HTL) in perovskite solar cells (PSCs) due to its wide optical bandgap and superior stability. In this study, we have modulated the Ni2+vacancies in NiOxfilm by controlling deposition temperature in a hot-casting process, resulting the change of coordination structure and charge state of NiOx. Moreover, the change of the HOMO level of NiOxmakes it more compatible with perovskite to decrease energy losses and enhance hole carrier injection efficiency. Besides, the defect modulation in the electronic structure of NiOxis beneficial for increasing the electrical conductivity and mobility, which are considered to achieve the balance of charge carrier transport and avoid charge accumulation at the interface between perovskite and HTL effectively. Both experimental analyses and theoretical calculations reveal the increase of nickel vacancy defects change the electronic structure of NiOxby increasing the ratio of Ni3+/Ni2+and improving the p-type characteristics. Accordingly, an optimal deposition temperature at 120 °C enabled a 36.24% improvement in the power conversion efficiency compared to that deposited at room temperature (25 °C). Therefore, this work provides a facile method to manipulate the electronic structure of NiOxto improve the charge carrier transport and photovoltaic performance of related PSCs.

As an emergent energy carrier, ammonia benefits from a well-established industrial infrastructure for its transportation and production, positioning it as a promising candidate toward a carbon-free energy landscape. Within this context, the electrocatalytic ammonia oxidation reaction (AOR) is pivotal. Platinum (Pt), recognized as the most efficient AOR catalyst, has undergone extensive development over the years, yielding notable advancements across various domains, ranging from elucidating the reaction mechanism to exploring innovative materials. This review begins by elucidating the mechanism of ammonia oxidation, summarizing the evolution of the mechanism and the diverse intermediates identified through various detection methods. Subsequently, it outlines the research progress surrounding different Pt-based catalysts, followed by a discussion on standard protocols for electrochemical ammonia oxidation testing, which facilitates meaningful comparisons across studies and catalyzes the development of more efficient and potent catalysts. Moreover, the review addresses current challenges in ammonia oxidation and outlines potential future directions, providing a comprehensive outlook on the field.

Hot-casting is a promising technique of depositing high-quality organic–inorganic hybrid perovskite thin films with large crystal grain size. Here, we reported the that the crystallinity and grain size of perovskite films could be systematically tailored by modulating the stoichiometry of the precursor solution in the hot-casting process under ambient condition with a relative humidity of 40%. It was found that a slight excess of methylammonium iodide (MAI) in the precursor solution could effectively compensate the MAI loss due to the high substrate temperature. A significant increase in the grain size and crystallinity of the perovskite film was observed together with a decrease in defect density and a carrier concentration enhancement in MAI-rich samples. The corresponding devices exhibited a notable increase in fill factor (up to 80.70%) and short-circuit current density. In addition, in MAI-deficient samples, an enrichment of PbI2at the grain boundaries was directly observed by optical microscopy and laser confocal microscopy. Time-resolved photoluminescence spectroscopy revealed an increase in the charge carrier lifetime in the MAI-deficient samples, which was in line with the previous results with a small amount of excess PbI2in the perovskite film. This work highlights a new strategy to prepare high-quality perovskite thin films with excellent crystal quality under ambient condition.

The production of ammonia (NH3) in the industrial scale basically relies on the traditional technology of Haber–Bosch, which is operated under harsh conditions with high energy consumption and a huge number of greenhouse gas emissions. Electrochemical N2reduction reaction (NRR) is a promising route for artificial N2-to-NH3fixation with less energy consumption. However, an effective electrocatalyst, as a prerequisite of the NRR, is of significance. Here, we report that a spinel LiMn2O4nanofiber acts as a noble-metal-free electrocatalyst for NH3synthesis with excellent performance under ambient conditions. The electrocatalyst, which was tested in 0.1 M HCl, has an excellent Faradaic efficiency of 7.44% and a NH3yield of 15.83 μg h–1mgcat.–1at −0.50 V versus reversible hydrogen electrode. Moreover, it also possesses excellent electrochemical and structure stability.

Mg–Al alloys were inoculated by MgO powder. The effects of MgO addition amount, holding time after MgO addition and Al content on the grain refining efficiency were systematically investigated in the present study. The refining mechanism was discussed. MgO cannot serve as the effective substrate of primary α-Mg phase. Significant grain refinement of Mg–Al alloys with the Al content over than 2% could be obtained. Al is an indispensable element to ensure the grain refining efficiency of MgO addition on Mg alloys. The optimum MgO powder addition amount and the holding time were about 1.5% and 10 min, respectively. MgO could react with Al in Mg melt, resulting in the formation of MgAl2O4particles. As the comparative experiments, the grain refinement on the pure Mg and Mg–3%Al alloy inoculated by MgAl2O4powder was proven. Based on theoretical calculation and experimental results, the grain refinement of Mg–Al alloy inoculated by MgO powder is attributed to the newly formed MgAl2O4particles, which could act as the effective heterogeneous nuclei of primary α-Mg phase.

The interfaces play a significant role in enhancing the photoelectric properties and stability of the perovskite solar cells (PSCs). In this work, we performed first-principles density-functional-theory (DFT) calculations to examine the interaction between CH3NH3PbI3and BaSnO3perovskite. The interfacial structure–property relationships of pristine CH3NH3PbI3/BaSnO3have been thoroughly explored by theoretical computations. The results of interfacial binding strength and electronic structure indicate that the combination of SnO2/PbI2has the strongest interfacial interaction and charge transfer capability. The enhanced interfacial interaction between CH3NH3PbI3and BaSnO3is beneficial for electron–hole separation. Moreover, the lanthanum-doped CH3NH3PbI3/BaSnO3interfaces are also investigated to explore the impact of lanthanum doping on the properties of CH3NH3PbI3/BaSnO3. The geometric, electronic, and optical characteristics of the CH3NH3PbI3/BaSnO3interface with lanthanum dopant at different positions have been evaluated. We found that lanthanum dopant was energetically stable at the subsurface layer. The doping depth has a negligible influence on the interfacial charger transfer. Lanthanum doping has been demonstrated to be workable for enhancing the n-type conductivity in BaSnO3while the excellent transport property is preserved. La incorporations effectively reduce the conduction band level of BaSnO3, which will make the interfacial band alignment more suitable for the electron transfer. Finally, the absorption coefficients and interband transitions are well estimated to understand the light trapping capacity. This work provides an atomic insight into the interfacial interaction between CH3NH3PbI3and BaSnO3, which can help us to obtain to new strategies for optimizing the PSCs interfaces.

Despite the major improvements in device efficiency, perovskite solar cells (PSCs) are limited by their poor stability due to the degradation toward moisture. Recently studies have demonstrated that the perovskite materials can be stabilized by adding more inorganic elements such as Cs and Rb. However, the specific mechanism is not yet fully established. In this paper, first-principles calculations were employed to investigate the effects of Rb incorporation and water degradation on cubic formamidinium lead iodide (FAPbI3) perovskite. The termination dependence of the structural stability of the representative (100), (010), and (001) surfaces was characterized by surface energies. The PbI2-terminated (001) surface was found to be the most stable surface structure. The Rb dopants were found to be energetically favorable, existing on the surface more than staying in the inner atomic layers. Furthermore, the degradation mechanism was investigated by water adsorption on the Rb-incorporated FAPbI3(001) surface. According to our calculations, the water molecules tend to interact with the surface on the Pb-top sites with the largest adsorption energy. The orientation of the surface FA cations exerted a crucial influence on the adsorption energy as well as the surface energy. The moisture-induced decrease in optical absorption in the visible region could be observed in absorption spectra. It indicates that the adsorbed water molecules subsequently reduce the conversion efficiency. More importantly, we find that Rb incorporation at the surface region with the largest adsorption energy will destroy the surface structure leading to the obvious drop in the absorption spectra. These findings further illustrate the initial degradation process of Rb-incorporated FAPbI3under the humid condition, which should be helpful to improve the stability of Rb-doped FAPbI3perovskites in the presence of moisture.

Photocatalysis technology is one of the hotspots in recent years to solve a series of social problems such as energy crisis and environmental pollution. It is an important way to improve the photocatalytic efficiency by constructing heterojunction and improving the utilization rate of sunlight. In this paper, nitrogen-doped rutile titania and graphite phase carbon nitride composites were synthesized successfully. Although nitrogen-doped rutile titanium dioxide cannot meet the thermodynamic conditions of hydrogen production, the photocatalytic hydrogen production rate of nitrogen-doped rutile titania/graphitic carbon nitride composite reaches to 2121.9 μmol h−1g−1, which is 2.57 times higher than that of the pristine graphitic carbon nitride. By means of density functional theory, the band structure, state density, work function, differential charge density, and Bader charge distribution of the samples were analyzed. It was revealed that the Z-scheme heterojunction formed at the carbon nitride interface of nitrogen-doped rutile titanium dioxide/graphite carbon nitride effectively promoted the improvement of photocatalytic performance. This study provides a feasible idea for the design and popularization of new cheap photocatalysts in the field of renewable energy.

SO2and NO from coal combustion are the main precursors of acid rain, regional haze, and photochemical smog. Advanced oxidation strategies can be used to simultaneously remove SO2and NO from flue gas under a low temperature. Two metal-organic frameworks (MOFs), FeBDC and CuFeBDC, were synthesized and used to activate peroxymonosulfate (PMS) for the oxidation and absorption of flue pollutants. The characterization results revealed that MOFs contained the redox pairs Fe(II)/Cu(I) and Fe(III)/Cu(II). Fe(II)/Cu(I) initiated firstly the PMS activation. Then, the Fe(II-III-II) and Cu(I-II-I) redox cycles continuously activated PMS and generated reactive species. MOFs-PMS removed 76.6 % and 86.5 % of NO in the presence of FeBDC and CuFeBDC catalysts, respectively. 100 % of SO2was removed. CuFeBDC exhibited the efficient catalytic properties for the removal of NO and SO2in PMS solution, and could be recycled and regenerated. After five cycles, the removal efficiencies of NO and SO2were 71.2 % and 100 %, respectively, and NO and SO2emissions in the outlet were lower than the emission limit when using CuFeBDC-PMS. During the oxidation and absorption process, NO and SO2were first oxidized to NO2-and SO32-as intermediates, then formed the final products of NO3-and SO42-. Radical scavenging experiments and electron paramagnetic resonance measurements revealed that both radical (SO4-•, •OH) and non-radical pathways (1O2) contributed to the efficient oxidation of NO/ SO2. 1O2was the predominant reactive oxygen species for the removal of NO, while SO4-• and •OH were responsible for the removal of SO2.

Based on computational fluid dynamics and large-eddy simulation technologies, a numerical simulation method of a moving thunderstorm field is established by considering the impinging jet model. In addition, the influence of movement speed of the storm center and jet velocity changes on the characteristics of the wind field is presented. By drawing horizontal wind speed radial profile curves, the verticalprofile curves of horizontal wind velocity, radial wind profile curves of vertical wind speed, and transient wind speed characteristics of a moving thunderstorm downburst are illustrated. The results demonstrate that the wind field of a moving thunderstorm exhibits clear asymmetric characteristics. As the height from the ground increases, the horizontal wind speed first increases and then decreases. The extreme value of the horizontal wind speed appears at the position of (0.01–0.03) Djet (where Djet is the jet spout diameter) near the ground, which is consistent with the characteristics of a static thunderstorm wind field. Simultaneously, the distribution characteristics of wind pressure on the surface of wind turbines under moving thunderstorms is further studied. By considering variations of the wind attack angle, jet velocity, and moving speed, the results of wind pressure on the tower and blades of the wind turbine are presented. The coupling of the moving speed and jet velocity has a significant influence on the wind field and pressure on the wind turbine surface.

Deep-ultraviolet (DUV, λ ​< ​200 ​nm) nonlinear-optical (NLO) crystals play a pivotal role in modern laser science and technology. Metal phosphates have been considered as fascinating candidates for DUV NLO crystal material. However, how to generate both strong second-harmonic-generation (SHG) response and large birefringence for promising DUV NLO metal phosphates is a long-standing issue. Herein, a new DUV NLO metal phosphate, BaNa2[PO3(OH)]2, was successfully synthesized, which features a two-dimensional [NaPO3(OH)]∞alveolate layer alternately connected by highly asymmetric [PO3(OH)] groups and NaO5triangular bipyramids. BaNa2[PO3(OH)]2can realize a good balance of DUV nonlinear properties covering short UV absorption edge less than 190 ​nm, strong SHG response with the magnitude of ∼1.2 ​× ​benchmark KH2PO4(KDP), and the largest birefringence with the experimental value of 0.064@590 ​± ​3 ​nm in reported alkaline/alkaline-earth metal phosphates, producing the shortest phase-matching output down to the wavelength of 164 ​nm. These research results show that BaNa2[PO3(OH)]2crystal is a potential DUV NLO crystal material.

A new hyperspectral imaging system is constructed based on the idea of compressive sensing (CS). The compressed hyperspectral measurements are acquired and unmixed directly with the proposed algorithm which determines the abundance fractions of endmembers, completely bypassing high-complexity tasks involving the hyperspectral data cube itself. Without the intermediate stage of 3D hyper-cube processing, data reconstruction and unmixing are combined into a single step of much lower complexity. We assume that the involved endmembers' signatures are known and given, from which we then directly compute abundances. We also extend this approach to blind unmixing where endmembers' signatures are not precisely known a priori.

The electrochemical N2reduction reaction (NRR) demonstrates a process of NH3synthesis from N2molecules under ambient conditions, which is environmentally friendly and recyclable. However, it requires an efficient electrocatalyst to activate inert N2molecules, which is still difficult to satisfy. Recently, as an active NRR electrocatalyst and a typical metal oxide, CeO2has featured ultrahigh thermal stability and the ability to apply heteroatom doping, which is an imperative approach importing oxygen vacancy by replacing metal ions with selective elements to greatly influence the activity of catalysts. Here, we analyze the unique properties of manganese dopants in modulating the activity of CeO2nanospheres for NRR. It attains a larger NH3yield of 27.79 μg h–1mgcat–1and a higher Faradaic efficiency of 9.1% than pure CeO2at −0.30 V in 0.1 M HCl, with high electrochemical and structure stability. With calculations by density functional theory, the performance enhancement of Mn-doped CeO2is also proved mathematically.

Recent advances of a hot-casting technique used to deposit high-quality perovskite films are reviewed.Perovskite films with large grain size, uniform thickness, and preferred crystalline orientation are deposited.Future perspectives on the upscaling of perovskite solar cell are described.

By first-principles calculations, we carried out a comparative investigation of the hexagonal InN (0001)/yttria-stabilized zirconia (YSZ) (111) and cubic InN (111)/YSZ (111) interfaces. The calculated adsorption energies provide greater stability of hexagonal-phase InN than of the cubic one. The relatively large diffusion lengths in the N polarity case make it possible for adatoms to migrate and grow an atomically flat surface. The hexagonal interface has a smaller effective mass, and a highly dispersed band will lead to good electrical conductivity and strong delocalized bonds. This research provides fundamental understanding of the atomic structural and electronic properties of InN/YSZ interfaces.
