1.Characterization of particle size and distribution Dynamic Light Scattering (DLS): DLS is one of the most commonly used techniques for measuring the particle size and distribution of nanoparticles in suspensions. It calculates the hydrodynamic diameter of particles by measuring the time-dependent light scattering intensity fluctuations caused by Brownian motion of particles. DLS can also provide...

FeNi50 metal powder is a medium to high nickel iron-based alloy powder based on the iron nickel binary system with a nickel content of about 50 wt.%. Its typical characteristics include stable austenite structure, excellent thermal expansion matching ability, good toughness, and adjustable magnetic properties. In the material system, FeNi50 is between low nickel structural alloys and high nickel I...

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...

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...
