Graphene is famous as a two-dimensional material, but to really make the most of the stuff we need to coax it back into 3D forms. Now researchers from Virginia Tech have developed a new way to 3D print graphene aerogels with a far higher resolution than previously possible.

Aerogels are among the best thermal insulators, but their cloudy appearance doesn't work for windows, one of the worst offenders for letting heat escape a building. Now, researchers at Colorado University Boulder have found a way to make them transparent, recycling a beer by-product in the process.

Scientists from the National University of Singapore have found a new use for cotton-based fabric waste – they've devised a method of converting it into an aerogel. Among other things, the ultralight material could be used to keep water bottles cold, and to control bleeding from deep wounds.

Why bother adding a layer of insulation to a brick wall, if you can just build that wall using hollow bricks that are stuffed with insulation? That's the thinking behind bricks which incorporate materials such as perlite. Now, scientists have created the best-insulating brick yet, using aerogel.

Those of us who live and seek adventure in cold weather are familiar with the various thermal technologies available. With Oros, something is different. It's lightweight, thin, and yet warmer than many other options we've owned thanks to the use of NASA-inspired aerogel.

Scientists have created a solar cell of mutiple layers of different perovskite materials that has a claimed a peak efficiency of 26 percent. And can usefully convert light energy over much greater parts of the spectrum than standard silicon solar cells.

Known as "frozen smoke" because of their milky translucent appearance, aerogels are among the world's lightest solid materials. Now, scientists at the National University of Singapore (NUS) have used paper waste to create one.
