Light bends when travelling through a concentration gradient of sugar in water. The top layer of liquid is pure water while the bottom layer is concentrated sugar water. In these layers, there is no ...
Among the various sensing modalities available for bioprocess operations, index of refraction (IoR) is intriguing for its simplicity and capability for sample-less, real-time readout. A group led by ...
South Korea's ETRI is developing a transparent element with a variable refractive index. The transforming lens developed by ETRI researchers. The lens's curvature changes when an electric current is ...
