    How to reduce nanoparticle agglomeration

    What Is Nanoparticle Agglomeration? A single crystal grain or amorphous sphere obtained from synthesis is called a primary particle; when several primary particles touch and bind together into a larger unit, an agglomerate is formed. Agglomerates are usually divided into two classes according to the strength of the bonding: soft agglomerates are held together mainly by weak physical interactions s...

    Why EDS Cannot Measure Light Elements Accurately

    How Does EDS Identify the Spectral Lines of Light Elements? Energy-dispersive X-ray spectroscopy (EDS) is usually fitted to a scanning or a transmission electron microscope. An incident electron ejects an inner-shell electron from a sample atom; an outer electron then drops into the vacancy, and the energy difference between the two levels is emitted as a characteristic X-ray. A silicon drift dete...
