The Nature Index 2024 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Nanoscale optical components, such as lenses and waveguides, are used in imaging and computing platforms. Yet it’s challenging to make these components with more than one refractive index—a property ...

Researchers at Lawrence Livermore National Laboratory (LLNL), Livermore, CA, have employed multi-material 3D printing to create tailored gradient refractive index glass optics that could make for ...

A property of a material that changes the speed of light, computed as the ratio of the speed of light in a vacuum to the speed of light through the material. When light travels at an angle between two ...

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

Physicists at Harvard University in the US have built a silicon waveguide that exhibits a refractive index of, or close to, zero when operating at near-infrared telecom wavelengths. The waveguide can ...

Peak Nanosystems, the Valley View, Ohio, company that manufactures high-performance polymer optics based on nano-layered structures, has completed a new investment round worth $25 million. The finance ...
