In its current form, the new diffuser could be used to calibrate a wide range of imaging systems, but the researchers believe that their mechanism could ultimately lead to holographic video screens or ...

On-chip refractive-index monitors suit industrial process control and biodetection, as the UK company seeks commercialization partners. Winning venture capital (VC) funding is a major milestone for ...

The Refractive Index Matching (RIM) test rig at the University of Bristol is a specialised closed-circuit flow facility designed for high-resolution measurements within and around complex geometries.

The water content of hydraulic brake fluid affects boiling point, viscosity and the corrosive nature of the fluid. Brake overheating can boil fluids containing a significant amounts of water, causing ...

The applications of spectroscopic ellipsometry for the precise characterization of liquid-liquid and liquid-air interfaces include surface science, biomedical applications, thin film coatings, and ...

Researchers in Korea have created a new metamaterial with the most extreme positive index of refraction yet – a whopping 38.6. The metamaterial operates at terahertz frequencies and the team believes ...

Real-time monitoring of key biomarkers is a critical prerequisite for early disease diagnosis and personalized therapy. Early ...
