Materials

Scientists have developed a new type of hydrogel described as "super jelly," with a unique internal structure likened to molecular handcuffs enabling the soft material to be run over by a car without being crushed.

Researchers at Carnegie Science have developed an ultrahard diamond glass. Made entirely of crushed “soccerballs” of carbon, the new material also has high thermal conductivity and could find use in electronics.

Not only are most thermoset resins made from non-renewable sources, but they're also hard to recycle. Scientists have set about addressing those problems, by developing a new lignin-based, thermoset-like material that can be reused several times.

When it comes to keeping things cold, ice cubes are hard to beat … although the things do melt. Scientists have set about addressing that limitation, with reusable water-based "jelly ice cubes" that hold their shape at all temperatures.

Scientists at the Italian Institute of Technology have developed what they describe as the first biodegradable version of Velcro which, while it won't keep your shoes on, can be attached to plants for the purposes of environmental monitoring.

Adhesives that hold underwater are elusive, but could be useful for marine repairs or tissue healing. Researchers have now developed a new type of adhesive hydrogel that combines the underwater stickiness of mussels with the strength of spider silk.

Glitter spruces up everything from makeup to craft projects, but one thing it doesn’t improve is the environment. A new biodegradable glitter swaps out the plastic and aluminum for plant-based cellulose, which can be produced at scale.

As sunlight passes through a building's windows it can cause indoor temperatures to rise, to the point that the structure's air conditioning system has to be used. A new window material, however, blocks incoming heat while staying mostly transparent.

Currently, if you wish to track the electrical activity of someone's muscles, you have stick electrodes onto their skin. An experimental new technology, however, simply utilizes conductive fabric that's incorporated into washable pieces of clothing.

Although carbon fiber can be repaired and recycled to a certain extent, it's typically just discarded once damaged. According to a recent study, however, a new type of the material can be easily fixed or reused through the simple application of heat.

Facebook recently rebranded as Meta, with an eye toward the development of VR/AR tech. In one of its first projects since the announcement, it's collaborating with Carnegie Mellon University on the development of a touch-sensitive electronic skin.

Scientists have used cellulose derived from wood as the basis for a solid battery electrolyte, which is paper-thin and can bend and flex to absorb stress as the battery is cycled, while also offering record high conductivity.
