Coating

Plastic wraps and food containers generate huge amounts of waste. Now researchers at Harvard and Rutgers have developed a new plant-based, antimicrobial coating that can be sprayed onto food to keep it fresh, and easily washed off before consumption.
-
Researchers at Oxford have developed a new smart window coating that can be tuned on the fly to emit or reflect heat from the Sun in different amounts, reducing the energy costs of heating and cooling by up to a third.
-
Engineers at MIT have developed a new ultrathin material as light as plastic but stronger than steel. The durable material could be used in vehicles or electronics, and makes use of a manufacturing technique that was previously thought impossible.
-
Berkeley Lab engineers have developed a roof coating that can keep a building warmer or cooler, depending on the weather. When it’s warm out the material will reflect sunlight and heat, but it switches itself off in winter, reducing energy use.
-
New weapons against so-called “superbugs” are desperately needed. A new black phosphorus coating quickly kills bacteria and fungi, then dissolves within 24 hours – and best of all, bacteria can’t evolve resistance against this mode of attack.
-
Usually optical coatings either reflect or transmit a given color of light, but now researchers at the University of Rochester have developed a new class of optical coating that can both transmit and reflect the same wavelengths at the same time.
-
Adding “two-faced” nanoparticles could improve paints and coatings. With one face that attracts water and another that repels it, the particles arranged themselves in a flat layer on a painted surface and could make for paint with unusual properties.
-
Humans weren’t built for space travel. The immune system takes a beating, leaving us more vulnerable to infection. Astronauts have now tested a new antimicrobial coating on board the International Space Station (ISS), and found it kept space-faring bugs at bay for well over a year.
-
In cold places, ice and frost can be more than an annoyance – it can be downright dangerous for cars and planes. Now researchers from the University of Illinois at Chicago have developed a new anti-icing material that can apparently keep ice at bay much longer than existing technologies.
-
Goggles, glasses and windshield can fog up if there’s a difference in temperature or humidity. Researchers at ETH Zurich have developed a new anti-fog coating that warms up the surface without needing electricity.
-
Our phones follow us everywhere – which often puts them in the line of fire for spilt drinks or rain. But now a team at the University of Michigan has developed a durable, clear coating that could help phones – or any surface, for that matter – repel almost any liquid.
-
Soon we could start to see a new class of waterproof products that stay hydrophobic for the long haul. That's thanks to a breakthrough by University of Michigan researchers to create a water-repellent spray-on coating they claim is hundreds of times more durable than similar substances.
