Astronomers from Bulgaria and Egypt have performed multi-wavelength observations of a well-known blazar designated S5 ...

Band structure calculations based on density functional theory (DFT) with local or gradient-corrected exchange-correlation potentials are known to severely underestimate the band gap of semiconducting ...

A new blue fluorescent molecule set new top emission efficiencies in both solid and liquid states, according to a University ...

Researchers at the Leibniz Institute of Photonic Technology (Leibniz IPHT) in Jena, Germany, together with international ...

The band gap energy was estimated experimentally by measuring the change in optical absorption intensity as a function of photon energy in a wide range from visible to vacuum-ultraviolet wavelengths ...

These theoretical and experimental results clearly indicate the importance of the band-gap modification, especially in the band-edge regions, in both light harvest and carrier dynamics.

More pathways than previously thought can lead to optical topological insulators, materials with exciting properties that could have future ...

An actuable InP micromechanical structure suspended over a 1/spl times/-thick air-gap provides for the tuning of the cavity. Our design aims primarily for a device that is simple, robust and that can ...

MKS Inc., a global provider of enabling technologies that transform our world, has announced the next generation of Newport™ ODiate® Fluorescence Filter Sets, an expanded filter portfolio that ...
