A simple electrical method provides an alternative way to prepare graphene samples, according to researchers in India. Graphene—one-atom-thick sheets of carbon packed in a honeycomb structure—has ...

THE accompanying photographs (Fig. 1) represent a somewhat extraordinary manifestation—a single electrode arc. The discharge is produced by the application of alternating voltage of the order of 5 kv.

The Institute for Electronics and Electrical Engineers (IEEE) Industry Applications Society, Electrical Safety Committee held its annual electrical safety workshop (ESW) March 6-11, 2016. "Since its ...

Of all the methods of making big pieces of metal into smaller pieces of metal, perhaps none is more interesting than electrical discharge machining. EDM is also notoriously fussy, what with having to ...

There are a number of methods of making carbon nanotubes (CNTs) and fullerenes. Fullerenes were first observed after vaporizing graphite with a short-pulse, high-power laser, however this was not a ...
