Summary: The study focused on the catalytic efficiency of the AlMoGNi catalyst for the HDS of DBT, synthesized by loading Ni promoter on graphene and Mo catalyst on alumina separately, and then combining Ni/graphene with Mo/alumina. The AlMoGNi catalyst showed superior performance in reducing sulfur concentration in fuel compared to catalyst without graphene, attributed to its textural properties, surface acidity, and nanoparticle dispersion. The HDS process over the AlMoGNi catalyst involved hydrogenolysis and hydrogenation desulfurization pathways.

Summary: This study prepared cobalt-promoted molybdenum carbide supported on mesoporous alumina catalysts and systematically investigated the effects of cobalt on the physicochemical properties and hydrodesulfurization (HDS) performance of the catalysts. The results showed that suitable cobalt addition reduced the interaction between molybdenum species and alumina support, allowing for better carbonization of molybdenum. The introduction of cobalt made the molybdenum species electron-rich, resulting in easier attack on the C-S bond. The Co0.3Mo2C/MA catalyst exhibited significant sulfur removal efficiency and effective direct desulfurization selectivity.

Summary: This paper presents a method for the comprehensive recovery of valuable metals from spent Al2O3-based catalysts by using sodium carbonate roasting and water leaching. The results show that roasting is a critical factor influencing the leaching effect, as it converts insoluble compounds into soluble ones. The recoveries of Al and V reach 99.64% and 99.24% respectively under the optimal leaching conditions. The metal composition in the leachate and residue favors metal recovery compared to direct recovery from the spent catalyst. The addition of stoichiometric Ba(OH)(2) allows for the selective recovery of V, followed by the recovery of Al and Ni through precipitation and calcination.

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: For the first time, the formation of nanotwins and 9R phase were observed in ultrafine-grained Ti-5wt.%Cu alloys with an average lath width of 223 nm produced by laser powder bed fusion. The 9R phase originated from lath boundaries with Cu segregation and terminated at the other boundary of the lath. Deformation caused curvature of the lath boundaries and an increase in lath width, promoting the transition of the central 9R phase to nanotwins. This work provides a new route for in situ production of nanotwinned Ti by the laser melting-induced segregation of Cu.

Summary: Understanding the relationship between the physical properties of composite components and thermal conductivity is crucial for improving overall heat-dissipation performance. A numerical simulation was conducted to investigate the anisotropic thermal conductivity and heat flux distributions of h-BN/nanofiber composite films. Factors such as the intrinsic thermal conductivity of the matrix and filler, filler geometry and orientation, and interface thermal resistance were considered. The study found that increasing the intrinsic thermal conductivity of the matrix and tuning the interface thermal resistance could enhance the thermal conductivity, while the contributions from increasing filler conductivity and length were limited.

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.
