Desalination makes saltwater more palatable and potable, but being a bit of an energy guzzler means it isn't the most practical solution in off-grid situations. A new system makes use of nanoparticles to harness the power of the sun and distill water more efficiently, without needing electricity.

Rather than always replacing parts, fixing things or just throwing them away, self-healing materials can patch themselves up as required. Now, researchers at are working on extending the life of membranes in hydrogen fuel cells by equipping them with similar self-healing powers.

Engineers have used nanotechnology to model a new membrane that can filter salt from seawater at higher volumes than ever before. The membrane, made from molybdenum disulfide, “pulls” clean molecules water through itself. Potentially, this could make desalination plants much more energy-efficient.

In modern airliners, much of the structural paneling used in the cabin and wings has a honeycomb-like structure. Although this keeps the weight down while maintaining strength, it does a poor job at blocking noise. That's why researchers have developed a membrane that helps the panels to do so.

The Cougar 500K gaming keyboard may look a lot like the company’s high-end, mechanical 700K offering, but it actually makes use of lower-cost membrane tech. However, this won’t impact functionality as you might expect, with the 500K offering full N-Key Rollover.

ScienceA new study conducted at MIT suggests that tweaking the size of a costly membrane could help make pressure-retarded osmosis (PRO) much more competitive.

ScienceVanderbilt psychology Professor Geoffrey Woodman and graduate student Robert Reinhart have found that transcranial direct current stimulation (tDCS) of the mediofrontal cortex for a period of minutes can change a person's ability to recognize and learn from error for a period of five hours.

Researchers at Clemson University have discovered that inkjet bioprinting disrupts the membranes of the cells being printed, leaving them open to having proteins inserted.
