Based on the metal-semiconductor junction forming a Schottky barrier, Schottky diodes conduct electricity through majority carriers without minority carrier storage effect. Their core advantages include ultra-low forward voltage drop (0.2–0.45V), extremely fast switching speed (ns level), and low power loss. When forward-biased, the barrier decreases for rapid electron conduction; when reverse-biased, the barrier increases to […]
Faced with global energy shortages and growing environmental concerns, lithium-ion batteries have become the core solution for energy storage and power applications, thanks to their high energy density and long cycle life. They are widely adopted in power station energy storage systems, UPS communication power supplies, electric vehicles, aerospace and military equipment, with applications continuing […]
Niobium-titanium alloys feature outstanding corrosion resistance, high specific strength, excellent biocompatibility and superconducting properties. They are widely applied in critical fields including medical implants, aerospace, superconducting magnets, nuclear energy and chemical engineering, serving as core structural materials for high-end precision manufacturing. The mechanical properties and stability of the alloy are entirely determined by its microstructure. […]
Metallographic inspection of aluminum‑scandium alloys is critical for ensuring their high‑performance applications. It serves as an indispensable quality control method for process monitoring, parameter optimization, and reliable use in aerospace, high‑end equipment, and other advanced fields. As one of the most effective microalloying elements for strengthening aluminum alloys, scandium significantly refines grains and forms thermodynamically […]
Advanced materials are a strategic and foundational industry, representing the cutting-edge technology of emerging industrial chains. From April 9 to 12, the 1st China “AI + new materials” conference was grandly held in Nansha, Guangzhou. The conference was attended by over 50 academicians of the Chinese Academy of Sciences and Chinese Academy of Engineering, more […]
Nitriding is a low-temperature surface chemical heat treatment process that diffuses nitrogen atoms into the steel surface at 500-580℃. No subsequent quenching is needed, yet it drastically boosts the workpiece’s surface hardness, wear resistance, corrosion resistance and fatigue strength—with minimal deformation. It’s a core process in high-end mechanical manufacturing, widely applied to precision load-bearing components […]
