Multilayer graphene-gated carbon nanotube (CNT) emitters are introduced to novel vacuum-sealed x-ray tubes. We characterized field emission performances and electron-beam (Ebeam) converging of the ...

This view inside some of the most precious and rare museum specimens on Earth is helping scientists to better understand the story of life — and it's all done without a scalpel in sight.

The human brain actually lights up with signals known as ultra weak photon emotions (UPEs), which are a byproduct of metabolic processes. Researchers have now been able to detect UPEs and determine ...

The results suggest the Ir-Bi-Plastic array, despite its larger pixel pitch, provides significantly improved performance over equivalent arrays made from either EJ-200 or EJ-256 for all X-ray and fast ...
