On Pi Day, how scientists use this number

If you like numbers, you will love March 14, 2015. When written as a numerical date, it's 3/14/15, corresponding to the first six digits of pi (3.1415)—a once-in-a-century coincidence! Pi Day, which would have been the ...

Hydrocarbon photocatalysts get in shape and go for gold

A combination of semiconductor catalysts, optimum catalyst shape, gold-copper co-catalyst alloy nanoparticles and hydrous hydrazine reducing agent enables an increase of hydrocarbon generation from CO2 by a factor of ten.

Novel crumpling method takes flat graphene from 2D to 3D

Researchers at the University of Illinois at Urbana-Champaign have developed a unique single-step process to achieve three-dimensional (3D) texturing of graphene and graphite. Using a commercially available thermally activated ...

Better batteries inspired by lowly snail shells

Scientists are using biology to improve the properties of lithium ion batteries. Researchers at the University of Maryland, Baltimore County (UMBC) have isolated a peptide, a type of biological molecule, which binds strongly ...

New catalyst uses light to convert nitrogen to ammonia

Northwestern University scientists are the first to develop a catalyst that can perform a remarkable feat found only in nature: take nitrogen from the air and turn it into ammonia under natural conditions. No high temperatures ...

What exactly is Google's 'cancer nanodetector'?

Last week, US tech giants Google made a splash in the media, announcing plans to develop new 'disease-detecting magnetic nanoparticles'. This was almost universally welcomed – after all, trying to detect diseases earlier ...
