Bootstrap circuits are widely used in dc-dc converters to serve as top-side bias voltage supplies. After explaining how bootstrap circuits work, this article will show how versatile they can be ...

Scientists at Germany's Fraunhofer ISE have designed a triple-junction solar cell consisting of perovskite-perovskite-silicon subcells. The device reportedly achieves an efficiency of 20.1% and a ...

Danish researchers have built a selenium solar cell with the highest open-circuit voltage ever reported. They said that with further improvements in the optoelectronic quality of selenium, the ...

Biologists have constructed a programmable genetic "circuit" that can rewire cells to respond on demand to just about any signal desired. One version of the circuit makes human cells susceptible ...

The circuits are the largest ever published to date in eurkaryotic cells and a key step in harnessing the potential of cells as living computers that can respond to disease, efficiently produce ...

Biologists have created a protein unlike any found in nature, with the power to toggle a cell’s functions on and off. The scientists linked the artificial proteins together into circuits and ...
