    Application of gold nano powder in medical treatment

    Gold nanoparticles refer to ultrafine gold particles with a particle size between 1 and 100 nanometers. Unlike macroscopic gold, nanoscale gold exhibits significant surface plasmon resonance (SPR) effects, quantum size effects, and a huge specific surface area. These characteristics endow it with excellent optical, electrical, and catalytic properties in complex biological environments. In additio...

    Three mainstream technological directions for replacing conductive silver paste

    The development of conductive pastes began in the 1950s. In 1954, British scholar C.F. Powell first reported the method of preparing conductive pastes by suspending silver particles in organic solvents, laying the technical foundation. Subsequently, in the 1960s and 1970s, with the rise of thick film hybrid integrated circuits, precious metal conductive pastes such as silver paste and gold paste g...
