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...

XRD is an important means of characterizing phases. Strictly speaking, it can determine the existence of a certain phase, but cannot determine the absence of a certain phase, making it easier to distinguish between truth and falsehood. So, what is its detection limit? Firstly, we must emphasize that XRD analysis of elemental content is very inaccurate. If we have to say what the detection limit is...
