Nature is sharing a fun little recipe for whipping up the super-material graphene in a kitchen blender:

In Nature Materials, a team led by [Jonathan] Coleman [at Trinity College, Dublin,] (and funded by the UK-based firm Thomas Swan) describe how they took a high-power (400-watt) kitchen blender and added half a litre of water, 10–25 millilitres of detergent and [...]

Laboratory Equipment on a low-tech material that solves a high-tech problem, as chemical engineers figure out ways to make supercapacitors out of wood:

OSU chemists have found that cellulose – the most abundant organic polymer on Earth and a key component of trees – can be heated in a furnace in the presence of ammonia, and turned into the building [...]

Nature is predigesting our gasoline… or something like that. Researchers have found that you can get fuel out of some tough material by treating it with a chemical mixture that breaks it down:

But most of the biomass produced in agriculture and forestry lies unused in more-complex chains of sugars, for example lignin and cellulose.

These tough, recalcitrant materials, which [...]

Gigaom takes the two great tastes of home manufacturing and carbon crystalline structures and makes them taste great together with a 3D printer that creates objects out of graphene:

Mining and technology development company American Graphite Technologies announced this week that partner researchers at the Kharkov Institute of Physics in in Ukraine received final approval to begin researching [...]

I’m pretty sure Nature is blazing a new B-movie trail with this report on hormone-disrupting chemicals “rising from the dead”:

Environmental scientists have discovered that although these compounds are often broken down by sunlight, they can regenerate at night, returning to life like zombies.

“The assumption is that if it’s gone, we don’t have to worry about it,” says environmental [...]

Laboratory Equipment reports on byproduct of the sugar industry that happens to make a more effective, environmentally friendly cement:

New research from the Niels Bohr Institute shows that cement made with waste ash from sugar production is stronger than ordinary cement. The research shows that the ash helps to bind water in the cement so that it is stronger, [...]

Science Art: <i>Fulleride Cs3C60</i> by Dmitri Zaitsev and Joffe Ilya Naftolevich

This is a buckyball crystal, a form of carbon that no one had ever seen until the 1980s. Now, it’s starting to get used in all kinds of unexpected ways. Formally, this stuff is is known as Carbon-60 or buckminsterfullerene, because the molecule looks so much like a geodesic dome as envisioned by R. Buckminster Fuller.

Because of [...]

University of California, Riverside, researchers have made a very small breakthrough in the way computers work… one that might lead to big changes soon. They’re using atom-thin sheets of carbon to create an entirely new kind of logic circuit:

Graphene is a single-atom thick carbon crystal with unique properties beneficial for electronics including extremely high electron mobility and phonon [...]
