Researchers at the University of Tokyo have built a microscope that can detect a signal over an intensity range 14 times ...

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 ...

Refractometers are versatile in their design and use, and are able to provide results as refractive indices, or in other cases, as direct measurements of parameters such as soluble solids, sugar ...

Recent experiments that demonstrate the negative refraction of light could bring a heated scientific debate to a close, and give negative-index materials a positive future Figure 1: Negative-index ...

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 ...
