“New manufacturing process yields highest conductivity copper composites at bulk scale Researchers at Pacific Northwest National Laboratory (PNNL) have increased the conductivity of copper wire by about five percent. That may seem like a small amount but it can make …
“Physicists have created a broadband detector of terahertz radiation based on graphene. The device has potential for applications in communication and next-generation information transmission systems, security and medical equipment. The study came out in ACS Nano Letters. The new detector …
“New method generates precisely controlled graphene microbubbles with perfectly spherical curvature for lenses Tiny bubbles can solve large problems. Microbubbles—around 1-50 micrometers in diameter—have widespread applications. They’re used for drug delivery, membrane cleaning, biofilm control, and water …
“Twisting a monolayer and a bilayer sheet of graphene into a three-layer structure leads to new quantum mechanical states. Since the discovery of graphene more than 15 years ago, researchers have been in a global race to unlock its unique …
“Scientists can have ambitious goals: curing disease, exploring distant worlds, clean-energy revolutions. In physics and materials research, some of these ambitious goals are to make ordinary-sounding objects with extraordinary properties: wires that can transport power without any energy loss, or …
News Caltech Researcher Unveils Sensor that Rapidly Detects COVID-19 Infection Status, Severity, and Immunity
“One feature of the COVID-19 virus that makes it so difficult to contain is that it can be easily spread to others by a person who has yet to show any signs of infection. The carrier of the virus …
“A team of University of Arkansas physicists has successfully developed a circuit capable of capturing graphene’s thermal motion and converting it into an electrical current. “An energy-harvesting circuit based on graphene could be incorporated into a chip to provide …
“Self-erasing chips developed at the University of Michigan could help stop counterfeit electronics or provide alerts if sensitive shipments are tampered with. They rely on a new material that temporarily stores energy, changing the color of the light it emits …
