Nov 05, 2022 (Nanowerk News) Astronomers led by the University of Warwick have identified the oldest star in our galaxy that is accreting debris from orbiting planetesimals, making it one of the oldest rocky and icy planetary systems discovered in the Milky Way. Their findings are published in the Monthly...

Engineers develop a low-cost, quantum-dot-enhanced terahertz camera
Nov 05, 2022 (Nanowerk News) Terahertz radiation, whose wavelengths lie between those of microwaves and visible light, can penetrate many nonmetallic materials and detect signatures of certain molecules. These handy qualities could lend themselves to a wide array of applications, including airport security scanning, industrial quality control, astrophysical observations, nondestructive...

New materials could enable longer-lasting implantable batteries
Nov 05, 2022 (Nanowerk News) For the last few decades, battery research has largely focused on rechargeable lithium-ion batteries, which are used in everything from electric cars to portable electronics and have improved dramatically in terms of affordability and capacity. But nonrechargeable batteries have seen little improvement during that time,...
Can cosmic inflation be ruled out?
Nov 05, 2022 (Nanowerk News) Astrophysicists say that cosmic inflation – a point in the Universe’s infancy when space-time expanded exponentially, and what physicists really refer to when they talk about the ‘Big Bang’ – can in principle be ruled out in an assumption-free way. The astrophysicists, from the University...

New technique simultaneously locates multiple defects on microchip circuits
Nov 05, 2022 (Nanowerk News) Defective computer chips are the bane of the semiconductor industry. Even a seemingly minor flaw in a chip packed with billions of electrical connections might cause a critical operation in a computer or other sensitive electronic device to fail. By modifying an existing technique for...
