Printable supercapacitors

By / May 11, 2009

A UCLA team has reported in Nano Letters that it has “printed” a supercapacitor for the first time. The group, led by George Grüner, accomplished their feat by spraying carbon nanotubes onto paired sheets of film separated by a gel electrolyte. Each sheet acts a charge collector. News about Grüner’s work started appearing in 2007,…

Oddest announcement of the last few weeks: Peeling tape can emit X-rays

By / November 14, 2008

Maybe a newly rediscovered property of Scotch tape is the reason the 3M company has been doing better in the last few months than the rest of the stock market. The discovery/rediscovery, as reported in Nature, is that when you peel adhesive tape off its roll in a vacuum chamber, it emits some strong X-rays.…
