Thermodynamic magic enables cooling without energy consumption

Physicists at the University of Zurich have developed an amazingly simple device that allows heat to flow temporarily from a cold to a warm object without an external power supply. Intriguingly, the process initially appears ...

Research team building a computer chip based on the human brain

Today's computing chips are incredibly complex and contain billions of nano-scale transistors, allowing for fast, high-performance computers, pocket-sized smartphones that far outpace early desktop computers, and an explosion ...

Self-rolled tubes make miniature electronics

(Phys.org)—With downscaling as one of the main pursuits in electronics research today, scientists and engineers are developing a variety of miniaturization strategies, from those involving powerful microscopes to self-assembly ...

TDK intros ultra high-Q multilayer inductors

TDK Corporation presented the new MHQ1005P series of multilayer ceramic inductors with a Q factor that, depending on the type, is as good or much better than comparable, but more expensive, wirewound inductors. The new multilayer ...

Improving low-loss dielectric measurement technique

Scientists from NPL have developed improvements to a technique for measuring dielectric permittivity and loss of materials at MHz frequencies. The method used is named after two NPL scientists who developed in the 1930, Hartshorn ...
