Meteorite yields carbon crystals harder than diamond

(PhysOrg.com) -- Two new types of ultra-hard carbon crystals have been found by researchers investigating the ureilite class Haverö meteorite that crashed to Earth in Finland in 1971. Ureilite meteorites are carbon-rich ...

Chinese researchers develop new battery technology

A Chinese research team has developed a novel, environmentally friendly, low-cost battery that overcomes many of the problems of lithium ion batteries (LIB). The new aluminum-graphite, dual-ion battery (AGDIB) offers significantly ...

How Perfect Can Graphene Be?

Structure of new form of super-hard carbon identified

(PhysOrg.com) -- An experiment in 2003 formed what was believed to be a new form of carbon, but the findings were controversial. Now two teams of scientists have used different means to identify a three-dimensional network ...

Pencil drawing of a sensor actually is a sensor

Using graphite pencils to draw on regular paper, researchers can make some very inexpensive piezoresistive (PZR) sensors. Due to the piezoresistive effect, a sensor's resistance changes under an applied strain, allowing it ...
