Summary: Tungsten oxide (WO3) is a cost-effective and structurally adjustable electrocatalyst for the hydrogen evolution reaction (HER). However, its intrinsic activity for HER is unsatisfactory due to strong hydrogen adsorption energy. To address this issue, defect engineering by inserting hydrogen atoms into the interstitial lattice site of WO3 (H0.23WO3) is proposed. The H0.23WO3 electrocatalyst demonstrates significantly improved activity for HER, with low overpotential and long-term stability. This work enriches defect engineering strategies for enhancing catalytic performance and provides insights for the rational design of efficient HER catalysts.

Summary: The intrinsic hydrogen evolution reaction (HER) activity and mechanism of antiperovskite Ni3In1-xCuxN bulk cubic particles and multi-crystalline nanoplates are thoroughly investigated. The results show that stoichiometric Ni3In0.6Cu0.4N exhibits the best HER performance, with optimized OH* and H* adsorption free energy. Introducing specific amounts of Ni-Cu pairs helps facilitate water dissociation in the HER process. Moreover, Ni3In0.6Cu0.4N enables spontaneous water adsorption, possibly attributed to the shifted d-band center and polarizing effect from surface In-Cu charge distribution.

Summary: Electrochemical water splitting is a promising pathway for hydrogen generation, but the sluggish cathodic hydrogen evolution reaction kinetics limit its efficiency. Nitrogen-doped materials, like NiSe2@nitrogen-doped carbon, have been investigated as efficient electrocatalysts. The core-shell architecture and high pyridinic-N content in NiSe2@NC-500 degrees C play a crucial role in providing active centers, enhancing conductivity, and improving durability of the catalyst for HER.

Summary: Desalination of seawater is a main method for producing fresh water in many countries, but waste brine or concentrate rejects can have adverse effects on the environment due to high salinity. This study presents a simple process for reducing the salinity of concentrated brine and producing calcium and magnesium oxides, using an electrochemical system. By applying a DC potential, the system reduces the TDS of the brine solution and decreases cations and anions in the treated brine.

Summary: In this study, the microstructure, mechanical properties, and wear behavior of three Al-Si alloys were investigated. It was found that the Al-13.5%Si alloy showed higher microhardness and excellent wear resistance, attributed to the presence of a large amount of Diamond-Si hard phase. On the other hand, the Al-1.5%Si alloy exhibited poorer wear resistance, mainly due to the particle detachment mechanism.

Summary: The inclusion of both fibre and solid lubricants in polymers can enhance their tribological and mechanical performances. This study investigates the effects of incorporating flax fibres and graphene nanoplatelets (GNPs) in epoxy matrix composites on their tensile, microhardness, and adhesive wear behavior. It was found that the addition of flax fibres improved the stiffness and tensile strength of the epoxy, while the inclusion of GNPs reduced the interface temperature and coefficient of friction. The heat distortion temperature was identified as a key parameter controlling the wear behavior of the composites.
