A process for fabricating atom-thin processors can be used to produce at the nanoscale for smaller and faster semiconductors.
Briefs: Nanotechnology
A system was developed that can remove radioactive cesium contamination from porous structures such as brick and concrete that are hard to clean, as well as contamination from metal...
Briefs: Electronics & Computers
Researchers have developed a hybrid transformer that has the benefit of a full planar transformer design but uses a wire-wound secondary winding to keep the parasitic winding capacitances lower. Alone, planar transformers...
Briefs: Wearables
Researchers have created highly stretchable supercapacitors for powering wearable electronics that consist of crumpled carbon nanotube (CNT) forests. The supercapacitors demonstrated solid performance and...
