After a year of trial and error, Liyang Chen had managed to whittle down a metallic wire into a microscopic strand half the width of an E.coli bacterium — just thin enough to allow a trickle of ...

Why there’s a need to assess current-flow distribution. How an arrangement was made for the measurement using a controlled magnetic field, laser-induced current flow, and a subtle physics-materials ...

The film explains the measurement of electric current using ammeters, which quantify the flow of elementary charges in a circuit. It introduces the concept of amperes as a measure of the number of ...

The manipulation and control of electron spins, the fundamental building blocks of magnetic domains and spin textures, are at the core of spintronics. Of particular interest is the effect of the ...

Using a current limiter in boost converters for circuit protection. An easy-to-implement design idea to achieve the desired current limiting. 1. A current limiter is added to a power bank that has an ...

Imagine if your dead laptop or phone could charge in a minute or if an electric car could be fully powered in 10 minutes. While not possible yet, new research by a team of CU Boulder scientists could ...
