Massively faster, more scalable, and more energy efficient than electronic computation, single-shot tensor computing uses light’s amplitude and phase to store, process, and send data. It could "create a new generation of optical computing systems."

Non-recyclable, non-biodegradable, petroleum-based EPS (expanded polystyrene) foam packaging is not eco-friendly stuff. There could soon be a greener and snazzier-looking alternative, however, in the form of origami-folded cardboard.

After decades of physics-based theorizing, researchers have succeeded in creating a novel optical metamaterial using conventional materials. Its enhanced electromagnetic effect may make true one-way glass a reality and solar panels more efficient.

Scientists have developed what they call the most water-repellent surface ever. By giving it a liquid-like coating that defies usual designs, water will roll off the surface at angles 500 times shallower than other superhydrophobic materials.

Researchers have turned lignin into nanoparticles that can create a transparent coating with antifog properties or a colorful antireflective surface, transforming this abundant waste product into a useful material with diverse applications.

Adoption of wireless charging has been fairly slow, but it could pick up if it worked over longer distances. Now Aalto University engineers have developed a new system that can allow more efficient wireless power transmission over longer distances.

Ordinarily, wireless chargers emit an electromagnetic field in just one direction, limiting the number of devices they can charge at once. A new charger, however, produces a donut-shaped field, for the simultaneous charging of multiple gadgets.

Researchers in Europe have developed an entirely new form of carbon, one that bears similarities to the wonder material graphene but with some useful differences that could open up new possibilities in electronics and advanced lithium batteries.

Researchers have developed a photovoltaic device that has an external quantum efficiency of 132 percent. This impossible-sounding feat was achieved using nanostructured black silicon, and could represent a major breakthrough for solar cells.

Among other things, hydrophobic (water-repelling) surfaces can be used to keep medical devices germ-free, to help airplane wings shed ice, and to keep solar panels clean. A new process could soon make those surfaces much more durable.

Although superglues can be quite useful, they're typically made from harsh chemicals, plus it's very difficult to "unstick" them once they've set. Now, however, scientists have created a plant-based superglue that can easily be removed when needed.

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