THE scale method is still regarded as the most accurate and reliable method for measuring refractive index gradients and is extensively used in diffusion and sedimentation measurements. The ...

Dynamic light scattering (DLS) is a technique used to determine particle size distributions of bioformulations. Traditionally, DLS measurements have been used for studying dilute solutions, but ...

(Nanowerk News) This will potentially allow them to create more compact and efficient elements for lasers, sensors, and optical chips. Moreover, it proves the hypothesis that ITMO physicists had about ...
