Summary: Efficient electron transfer from photosensitizer to catalytic sites is crucial for effective artificial photosynthesis. In this study, it was found that simple fluorination of the organic linkers in the MIL-101(Fe) photocatalyst significantly increased the photocatalytic CO2-to-CO conversion rate. The fluorinated linkers enhanced the interaction between the photocatalyst and photosensitizer via hydrogen bonding, facilitating their intermolecular electron transfer. This strategy can also be applied to other Fe-based metal-organic frameworks photocatalysts.

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: 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: The effect of grain boundary stability on the properties of Cu-Ni nanocrystalline alloy was investigated by molecular dynamics simulations. It was found that a more stable grain boundary leads to a higher energy barrier for deformation mechanisms and requires more force to hinder atomic slip in the grain boundary. The material reaches its highest strength when the homogeneous segregation degree of nanograined metals is about 0.9. Additionally, the binding energy between dislocations and grain boundaries was studied comprehensively and deeply for the first time using molecular dynamics simulation.
