If you studied advanced physics at high school, there's a good chance that you remember Snell's law, which states how a ray of light bends when it crosses a boundary between two media. According to ...

Accurate determination of refractive index is fundamental to optical metrology, underpinning applications from precision length measurement to material characterisation and environmental sensing.

In this way, and almost by chance, researchers at TU Wien developed a novel microscopy technique that allows the refractive index of biological samples to be measured at a resolution far below what ...

Ionic liquids (ILs) have drawn much attention due to their extensive applications and environment-friendly nature. Refractive index prediction is valuable for ILs quality control and property ...
