Summary: Large-surface-area, nanostructured films composed of 2D TMDCs building blocks were self-assembled using a customized metallic sulfide template. Control of 2D/2D contact properties in these films was explored through variations in building block sizes and film-forming processes. The study revealed that the surface area, density, and boundary angles of 2D/2D contacts are key parameters controlling the recombination of photogenerated carriers.

Summary: WO3 and CuO/WO3 samples were compared for their photocatalytic performance in methanol reforming. CuO/WO3 exhibited 64 times higher hydrogen production activity than bare WO3. CuO/WO3 had mixed-valence state, activating the lattice oxygen of WO3 to form oxygen vacancies. The oxygen atom of CH3OH was fixed at the vacancies, facilitating O-H bond cleavage. The study provides a method to improve catalysts for methanol photocatalytic reformation.

Summary: This study presents a comprehensive model for the bending behavior of hooks under contact loading conditions, which is relevant to reusable hook attachment systems. Physical testing was performed with stainless-steel and aluminum hooks, showing good agreement with the model. All parameters defining the hook transform to approximately linear functions of displacement in dimensionless form, allowing for rapid calculation of dimensional force versus displacement for a hook.

Summary: This study successfully synthesized and deposited MgB2 thin films on a gold surface using a wet-chemistry colloid synthesis and deposition process, circumventing the extreme conditions of conventional physical deposition methods. Gas adsorption experiments, X-ray photoelectron spectroscopy (XPS), and atomic force microscopy (AFM) characterization were conducted to validate the functionality and obtain meaningful data of the deposited MgB2 films. A similar synthesis method was applied on an evaporated Au film on glass, and the film thickness was measured to be 3.9 nm using scanning transmission electron microscopy (STEM). AFM roughness measurements confirmed the successful mitigation of the coffee-ring effect.
