Southampton optical circuit start-up Stratophase has developed a sensor that can measure the refractive index of liquids to better than one part in a million (1ppm). After the team got their prototype ...

Few people today would dispute that the use of Mie Theory provides the only route to accurate particle size analysis when measuring fine particles using laser diffraction. The international standard ...

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 ...

Utilizing Index of Refraction Monitors in Biopharmaceutical Downstream Processing and Purification When the FDA published the 2003 document, “Pharmaceutical Current Good Manufacturing Practices (CGMPs ...

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

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 ...

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 ...
