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.Conti… Continue reading Novel optical metamaterial may make true one-way glass a reality
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.Continue R… Continue reading World’s most water-repellent surface surprises its own inventors
Researchers have developed a quick and easy way to turn the wood-based bioproduct lignin into nanoparticles that can create a transparent coating with anti-fog properties or a colorful antireflective surface. The discovery transforms this abundant wast… Continue reading Wood waste transformed into transparent, anti-fog coating
Researchers have mapped where and how strongly we experience different kinds of love, covering everything from romantic love to love for strangers. The findings shed light on how context affects subjective feelings and adds to existing research on the … Continue reading Where in our bodies do we feel love (and other emotions)?
Adoption of wireless charging has been fairly slow, but it could pick up if it worked over longer distances. Now, engineers at Aalto University have developed a new system that can allow more efficient wireless power transmission over longer distances…. Continue reading Wireless charging technique boosts long-distance efficiency to 80%
Using a newly developed virtual reality game, researchers believe they have created a novel tool that can objectively diagnose attention-deficit hyperactivity disorder (ADHD). The system tracks a user’s eye movements and has also been proposed as a way… Continue reading VR eye-tracking game proposed to objectively diagnose ADHD
Ordinarily, wireless chargers emit an electromagnetic field in just one direction, limiting the number of devices they can charge at once. An experimental new charger, however, produces a donut-shaped field, for the simultaneous charging of multiple ga… Continue reading Cylindrical wireless charger juices up devices placed all around it
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. The incredibly thin sheets of material offer some electrical properties that other forms … Continue reading Entirely new form of carbon follows the lead of graphene
We’re quickly learning more about time crystals, strange phases of matter that appear to break time-translation symmetry – something that was thought impossible until recently. Now scientists have observed two time crystals interacting for the first ti… Continue reading Physicists witness time crystals interacting for the first time ever
Researchers at Aalto University 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 and other photodetectors.
