Electrical Circuits in Nature

Did you ever imagine the existence of an electrical circuit in Nature? Well, recent discovery has confirmed the existence of Nanowires, that are used by colonies of bacteria to transport electrons. These Nanowires are constructed out of protein molecules that self-assemble themselves into long filaments and have been shown to conduct measurable current between two electrodes.

From Capacitors to Ultracapacitors

Ultracapacitors challenge electrochemical batteries in specific applications…Circa 1971, that was the era when radio receivers built around vaccum tubes were not yet phased out. As a kid, I used to watch my dad assemble those bulky contraptions in his lab at home, and used to wonder at one cylindrical shining component on the chassis that stood out tall compared to others. As I later learned, that was the electrolytic capacitor used to filter out AC ripples from the output of the full wave rectifier circuit.
