Polymer membranes with molecular-sized channels that assemble themselves

Many futurists envision a world in which polymer membranes with molecular-sized channels are used to capture carbon, produce solar-based fuels, or desalinate sea water, among many other functions. This will require methods by which such membranes can be readily fabricated in bulk quantities. A technique representing a significant first step down that road has now been successfully demonstrated.

Trapped sunlight cleans water

A ew system that combines two different technologies proposes to break down contaminants using the cheapest possible energy source, sunlight. Microfluidics - transporting water through tiny channels - and photocatalysis - using light to break down impurities - come together in the science of optofluidics.

New glass tops steel in strength and toughness

Glass stronger and tougher than steel? A new type of damage-tolerant metallic glass, demonstrating a strength and toughness beyond that of any known material, has been developed and tested by a collaboration of researchers with the Berkeley Lab and the California Institute of Technology. What's more, even better versions of this new glass may be on the way.
