Researchers Advance Scheme to Design Seamless Integrated Circuits Etched on Graphene: UC Santa Barbara researchers demonstrate seamless designing of an atomically-thin circuit with transistors and interconnects etched on a monolayer of graphene

Researchers in electrical and computer engineering at UC Santa Barbara have introduced and modeled an integrated circuit design scheme in which transistors and interconnects are monolithically patterned seamlessly on a sheet of graphene, a 2-dimensional plane of carbon atoms. The demonstration offers possibilities for ultra energy-efficient, flexible, and transparent electronics.

Stealth nanoparticles lower drug-resistant tumors' defenses

Some of the most dangerous cancers are those that can outmaneuver the very drugs designed to defeat them, but researchers are now reporting a new Trojan-horse approach.

ALMA Probes Mysteries of Jets from Giant Black Holes

eso1344a_0.jpg
Two international teams of astronomers have used the power of the Atacama Large Millimeter/submillimeter Array (ALMA) to focus on jets from the huge black holes at the centres of galaxies and observe how they affect their surroundings. They have respectively obtained the best view yet of the molecular gas around a nearby, quiet black hole and caught an unexpected glimpse of the base of a powerful jet close to a distant black hole.

A chameleon in the physics lab: Looking cooler when heated, a thin coating tricks infrared cameras

Active camouflage has taken a step forward at the Harvard School of Engineering and Applied Sciences (SEAS), with a new coating that intrinsically conceals its own temperature to thermal cameras.

Project aims to mass-produce 'nanopetals' for sensors, batteries

Researchers at Purdue University are developing a method to mass-produce a new type of nanomaterial for advanced sensors and batteries, with an eye toward manufacturing in the Midwest.

These color-enhanced scanning electron microscope images show nanosheets resembling tiny rose petals. The nanosheets are key components of a new type of biosensor that can detect minute concentrations of glucose in saliva, tears and urine. The technology might eventually help to eliminate or reduce the frequency of using pinpricks for diabetes testing.
