Ultrafast extreme ultraviolet (XUV) spectroscopy is a powerful technique for probing the dynamics of atoms and molecules with attosecond time resolution. However, conventional XUV absorption ...

A new method is presented for the extraction of the complex index of refraction from the extinction efficiency, \(Q_{ext} {({\tilde{\nu }})}\), of homogeneous and layered dielectric spheres that ...

According to the increasing need in sensing applications for high accuracy and processing speed, and at the same time compressing the structure to make the sensors portable and cost-effective, light ...

Researchers have harnessed the light-guiding properties of spider silk to develop a sensor that can be used to determine concentrations of fructose, sucrose and glucose sugars based on changes in a ...

The Brix scale, derived from the refractive index of a solution at 20 degrees Celsius (68 Fahrenheit), is widely known. Originally, it was established by determining the weight percentage of sucrose ...
