Summary: This paper discusses the electrocatalytic behavior of stainless steel in water electrolysis and its potential as a replacement for precious metals electrocatalysts. Surface modification of stainless steel is shown to affect its electrocatalytic ability. The catalytic activity and long-term stability of stainless steels in hydrogen evolution and oxygen evolution reactions are comparable or sometimes better than those of noble electrocatalysts. Overcoming existing challenges such as the lack of active centers and low overall stability could make stainless steel a viable alternative to precious metals electrocatalysts.

Summary: Methyltetrahydrofuran (MTHF) can be produced from non-edible biomass as a clean liquid fuel for internal combustion engines. However, the conventional method of electrochemical hydrogenation (ECH) faces challenges in producing MTHF in significant yields. In this study, a membrane reactor is used to successfully produce MTHF through electrochemically-driven hydrogenation of furfural, demonstrating higher selectivity and current densities compared to single-cell ECH. Furthermore, the reaction pathway in the membrane reactor is mapped out, showing a different pathway than in single-cell ECH.

Summary: A novel set of Lennard-Jones parameters for amorphous silica is proposed in this study, capable of accurately simulating the structure. The existence of a compressed liquid layer at the liquid-nanoparticle interface is observed experimentally, with higher density and lower self-diffusivity of the molten salt mixture in proximity to the interface. Ordered distribution of Na+ and K+ ions is indicated at the interface, suggesting the presence of an ordered double-layer.

Summary: The study examined the influence of vacancy defects on the wettability of molten alkali metal salt on the CaO surface using molecular dynamics simulations. The results indicated that higher temperatures and defect concentrations led to poorer wettability of Na2SO4. This was attributed to induced polarization caused by the defect surfaces, ultimately affecting thermal energy transportability at the interface.
