Summary: Boron monoposphide (BP) has unique physical and chemical characteristics, making it suitable for various practical applications. However, the difficult synthesis of the single phase of boron monophosphide limits its usage. Additionally, existing methods for synthesizing nanoscale BP often require high temperatures and long synthesis durations. This paper presents a simple, energy-efficient, and straightforward microwave activation synthesis method, which successfully produces pure single-phase BP nanopowder with a narrow size distribution (70-90 nm) in a short synthesis time (10 min).

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
