Summary: Utilizing electrocatalytic reduction of CO2 to synthesize carbamates is an effective method of CO2 utilization. Developing high-performance electrocatalysts can efficiently promote this process for sustainable development. Single-atom catalysts, like the atomically dispersed Cu species on N-doped carbon nanosheet composite material (Cu-N-C), show potential to enhance the reaction process. The Cu-N-C material exhibits superior catalytic performance in synthesizing methyl N-phenylcarbamate, with an optimized yield of 71% at room temperature and normal pressure. It also demonstrates good stability after repeated use and broad applicability to convert various amines into carbamates smoothly.

Summary: In this study, a low crystallinity CuO-SnO2/C catalyst was synthesized by integrating CuO and SnO2 on carbon black, which exhibited significantly enhanced selectivity, activity, and stability towards the reduction of carbon dioxide. The well-distributed CuO and SnO2 nanoparticles on carbon black resulted in a larger electrochemically active surface area (ECSA) and faster electron transfer capacity, contributing to the enhanced electrocatalytic process. The low crystallinity of CuO on CuO-SnO2/C facilitated the easier electron transfer to the CO2 surface, accelerating the reduction reaction. The obtained CuO-SnO2/C with low crystallinity efficiently catalyzed the reduction of CO2 to formic acid and syngas, with a high Faradaic efficiency (FE) of C1 products (HCOOH + CO) of 80%, and 100% FE can be utilized.

Summary: Amino-specified pyrazolium ionic liquid (APEPzBr) is synthesized by two steps, and it is found that the product of the first step can also catalyze the coupling reaction of CO2 and epoxides. The ability is attributed to the strong absorption of CO2 and robust electrophilic activation of the product, as confirmed by density functional theory and C-13 NMR measurement, with further elucidation of the difference between the product and APEPzBr using ELF and AIM analysis.

Summary: Composite CO2 sorbents were obtained by impregnating an amino acid ionic liquid into mesoporous silica gel. At lower loadings, the sorption is fast and the capacity is proportional to the mass content of the ionic liquid. At higher loadings, the sorption rate decreases due to hindered mass transfer. An increase in CO2 concentration leads to faster sorption and higher capacity. Physical adsorption/absorption processes contribute more to total sorption capacity at higher CO2 concentrations.

Summary: Dispersion-strengthened copper matrix composites with Mo2C particles were fabricated by powder metallurgy and rolling. The Cu-5Mo2C composite showed the best combination of performances among the three composites. Its as-rolled form exhibited a tensile strength of 405.3 MPa, a hardness of 130.7 HV, and an electrical conductivity of 88.4% IACS. The primary strengthening mechanisms were grain boundary strengthening and dislocation strengthening. The Mo2C particles stabilized the microstructure and inhibited grain coarsening of the matrix, resulting in improved high-temperature softening resistance and mechanical properties for copper alloys.

Summary: By conducting high-resolution transmission electron microscopy and random field theory informed discrete dislocation dynamics simulations, this study reveals the influence mechanism of heterogeneous lattice strain on the complex interaction between dislocations and dislocation loops in high entropy alloys (HEAs) under irradiation. The results show that lattice-strain-induced irradiation hardening decreases, in line with the excellent irradiation hardening resistance of HEAs observed in recent experiments. A new cross-slip mechanism is also discovered, involving the co-linear reaction between dislocations and rhombus perfect loops. This study provides insights into the mesoscopic-level irradiation damage behavior, guiding the development of advanced HEA materials for nuclear energy applications through the regulation of heterogeneous lattice strain.

Summary: Additive manufacturing is believed to open a new era in precise microfabrication. This study investigates the microstructure evolution of a prototype multi-principal-element alloy FeCrNi fabricated using selective laser melting (SLM) through experiment and simulation. The results reveal the growth of columnar crystals across cladding layers and the development of dense cellular structures in the filled crystal. At the micron scale, the constituent elements are evenly distributed, while at the near-atomic scale, segregation of Cr element is observed. Simulation results demonstrate changes in the solid-liquid interface and the formation of precipitates, microscale voids, and stacking faults due to the thermal gradient, resulting in residual stress in the SLMed structure. A microstructure-based physical model reveals the presence of strong interface strengthening in tensile deformation.

Summary: A series of Cu-10Fe-xSi (x = 0, 0.8, 1.6 wt%) alloys were prepared and the effects of Si content and a novel multi-stage thermomechanical treatment on the microstructure, mechanical, electrical, and magnetic properties of the alloys were studied. The results showed that the Cu-10Fe-0.8Si alloy exhibited higher strength, magnetic permeability, and excellent electromagnetic shielding performance compared to the Cu-10Fe alloy. After peak aging treatment, the Cu-10Fe-0.8Si alloy demonstrated a tensile strength of 593.6 MPa, conductivity of 55.66% IACS, elongation of 22.8%, and relative magnetic permeability of 1.57. The addition of an appropriate amount of Si element resulted in the formation of a dual-scale FeSi phase in the alloy, which promoted the precipitation of Fe atoms and refined the alloy grains, thereby improving the strength and magnetic properties synergistically.

Summary: A precipitate-gradient Ti-W alloy with simultaneous high strength and high ductility was prepared by powder metallurgy and subsequent heat treatment. The high strength was mainly caused by solid strengthening and precipitation strengthening, while the gradient structure enhanced the strength through the generation of hetero-deformation induced stress. The good ductility and superior strain hardening capability were attributed to the activation of multiple deformation modes around the gradient interface during plastic deformation.

Summary: Water-quenched copper slag modified with alumina has been proven to be a viable substitute for cement. However, the impact of alumina on the structural properties and pozzolanic activity of the slag has not been thoroughly studied. This research characterizes the structural properties and pozzolanic activity of the slag with varying amounts of alumina using various analytical techniques. The results show that the addition of alumina improves the pozzolanic activity of the slag, but the effect is dependent on the curing age of the slag.

Summary: A Cu35Ni25Co25Cr15 high-entropy alloy (HEA) coating was deposited on a pure Cu substrate by plasma transfer arc (PTA) welding to enhance its surface hardness and wear resistance. The coating consisted of Cu-rich A1 phase and NiCoCr-rich γ' phase, with an apparent structural gradient and different microstructures in different zones. The coating exhibited improved interfacial bonding with increased welding current, but the hardness showed a non-monotonic trend. At a welding current of 150 A, the coating showed good metallurgical bonding with the Cu substrate and excellent wear resistance, especially at high temperatures.

Summary: This study proposes a new parameter-inversion model for estimating bed roughness in hydrodynamic models. A numerical experiment was conducted to analyze the impact of various factors on the accuracy of inversed roughness. The results show that increasing the number of measurement stations and observed data significantly improves the model's robustness, with an optimal parameter setting of 3 stations and 30 observed data. The proposed model provides a new approach to estimating bed roughness parameters and can improve the accuracy of water-level forecasting.
