Functions of tensile and compressive strain on electronic and optical properties of B-doped monolayer arsenene.

Context: The structurals stability, electronic structure, density of states (DOS), and optical properties of B-doped arsenene under biaxial tensile and compressive strains were investigated using density functional theory (DFT) calculations. The doping system was found to exhibit good stability. The introduction of B atom transformed the originally indirect band gap of arsenene into a direct band gap.

Pyrrolic Nitrogen Boosted H Generation from an Aqueous Solution of HCHO at Room Temperature by Metal-Free Carbon Catalysts.

Hydrogen production from organic hydrides represents a promising strategy for the development of safe and sustainable technologies for H storage and transportation. Nonetheless, the majority of existing procedures rely on noble metal catalysts and emit greenhouse gases such as CO/CO. Herein, we demonstrated an alternative N-doped carbon (CN) catalyst for highly efficient and robust H production from an aqueous solution of formaldehyde (HCHO).
