Coating

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.

Using superconducting, nano-particle infused ink, researchers have increased the efficiency of solar water heaters by up to 70 percent.
