Once upon a time I was a real mad scientist. I was into non-conventional propulsion with the idea of somehow interacting with the quantum vacuum fluctuations, the zero point energy field. I was into ...

Anyone who works with older electronic equipment will before long learn to spot Rifa capacitors, a distinctive yellow-translucent component often used in mains filters, that is notorious for failures.

Researchers at the Cavendish Laboratory, University of Cambridge have demonstrated a new way to control radiation in the terahertz range—an often-overlooked part of the electromagnetic spectrum—with ...

(Phys.org)—Capacitors are widely used in electrical circuits to store small amounts of energy, but have never been used for large-scale energy storage. Now researchers from Japan have shown that the ...

Electrochemical capacitors, also called supercapacitors, store energy using either ion adsorption (electrochemical double layer capacitors) or fast surface redox reactions (pseudo-capacitors). They ...

Researchers believe they’ve discovered a new material structure that can improve the energy storage of capacitors. The structure allows for storage while improving the efficiency of ultrafast charging ...

Hybrid "power capacitors" that can store as much energy as lithium batteries, but with much higher charge/discharge rates, a huge range of safe operating temperatures, super-long lifespans and no risk ...

When Ceramic Capacitors Go Bad – Aging. Capacitor Aging applies to all Class 2 ceramic capacitors as they are built of ferroelectric materials. C0G types (Class 1) do not exhibit this aging effect, ...

Defective capacitors--or "bad caps" as they are sometimes called--can disable your computer. And while they may not be widely familiar to consumers, they're nothing new to the PC industry. Capacitors, ...
