Materials

Ordinarily, if it's suspected that toxic airborne chemicals may be present in a given area, the analysis process can take several days. Now, however, scientists have developed a device that they claim can analyze the air within 10 seconds.

Refrigeration and air conditioning could use a boost in efficiency. On that road, researchers have now developed an unusual new technique that could lead to "twist fridges", which cool by unraveling fibers that are tensely twisted.

Scientists are claiming to have combined the best features of bio-based PLA plastic and traditional composite materials, with a new all-PLA composite.

A diamond with another diamond that moves freely inside it has been found. Dubbed the Matroyoshka diamond, it's the first known diamond of its kind.

Researchers at Rice University have developed a new air filter made of graphene foam, which can kill captured microbes with small zaps of electricity.

Scientists have developed a method of bending a single sheet of glass to a 90-degree angle.

Researchers have taken advantage of defects to make silver much stronger while still being conductive – breaking a theoretical limit in the process.

Scientists have developed a clingfish-inspired suction cup, that outperforms the actual fish itself.

Scientists are getting good results from an eco-friendly waterproof coating made of wax and starch.

Scientists have copied the porcupinefish's spines to create a water-repellent material that's more robust than previous efforts.

Making cement is one of the biggest contributors of carbon emissions. Now MIT researchers have developed a new method that can clean up the process.

A new substance is claimed to combine strength and toughness, by mixing wood fibers with spider silk.
