Chitosan refractive index
WebAug 5, 2014 · In that case, we have to know exactly how much light is scattered by each nanoparticle. And in order to predict that, Mie theory requires the refractive index and absorption of that particle. Secondly, for small nanoparticles of less than 100nm, the material properties will not even matter. As a result, the volume distribution obtained via DLS ... WebThe type of molecular order is controlled by the shape and chirality of liquid crystal molecules, with over one hundred known liquid crystal phases. Molecular alignment in liquid crystal films results in optical properties (e.g. refractive index, reflectivity, transmission) that can vary with wavelength (color) and polarization of incident light
