The crystal structure of nano iron oxide is hexagonal, and the lattice parameters change with the decrease of particle size. When the particle size is large (usually larger than tens of nanometers), iron oxide exhibits a typical α- The Fe2O3 structure, also known as hematite structure, is red in color. This is because typical α- The Fe2O3 structure has a high reflectivity for visible light, absorbing shorter wavelengths (blue-green) in visible light, leaving only longer red wavelengths observed.
Chemical Total Element Analysis (ICP-MS) is a widely used instrument technology in the field of chemical analysis. It is developed based on inductively coupled plasma mass spectrometry (ICP) technology.
Fisher's particle size is a method used to measure the particle size of granular materials, usually determined by measuring the settling velocity of particles in air or liquid. The principle of Fisher's particle size measurement is based on Stokes' law, which means that the force exerted on small particles in the medium is proportional to their diameter. The average diameter or particle size distribution of granular materials can be obtained using the Fisher particle size test.
Nanoparticle transmission electron microscopy (TEM) is an important microscopy technique widely used to observe and characterize the structure and morphology of nanoscale particles and materials.
Silver nanowire dispersion and silver nanowire ink are two common solutions containing nano silver wires, which have some differences in properties and applications.
Colloidal gold refers to a colloidal system formed by suspending nanoscale gold particles in an appropriate solution. The size of gold particles typically ranges from 1 to 100 nanometers.
