Coatings

Tired of your glasses fogging up on cold days, or of having to spit in your dive mask before putting it on? Those hassles may become a thing of the past, as researchers from Quebec City’s Université Laval have developed what they claim is the world’s first permanent anti-fog coating. Just one application is said to work indefinitely on eyeglasses, windshields, camera lenses, or any other transparent glass or plastic surface. Read More
Silver is a known killer of harmful bacteria, and has already been incorporated into things such as antibacterial keyboards, washing machines, water filters, and plastic coatings for medical devices. Now, scientists have added another potential product to the list: silver nanoparticle-impregnated “killer paper" packaging, that could help keep food from spoiling. Read More
Someone has apparently crunched the numbers and estimated that more than 100 million birds are killed every year due to collisions with glass surfaces – not to mention the untold numbers of beverages spilt by surprised people as a bird slams into a nearby window. Birds see the tree or sky reflected in a window or the environment behind the glazing, but not the glass itself. German company Glaswerke Arnold (or Arnold Glass) has come up with a simple way to prevent these collisions by producing a glass that appears normal to humans but is visible to birds. Read More
Deserts are the obvious locations for solar power plants. The land is cheap and the sunshine is plentiful. Unfortunately so too is the dust, dirt and wind that leads to dirty solar panels that can take a big hit in efficiency. Sending a guy around with a squeegee in the sweltering heat doesn’t sound like the best job in the world and self-cleaning systems that rely on water aren’t always an option in areas where clean water is hard to come by. Another solution is self-dusting solar panels that are cleaned by an electric charge provided by the solar panels themselves. The self-dusting solar panels are based on technology developed for another dry and dusty environment – Mars. Read More
Methicillin-resistant Staphylococcus aureus (MRSA), the bacteria responsible for antibiotic resistant infections, poses a serious problem in hospitals, where patients with open wounds, invasive devices and weakened immune systems are at greater risk of infection than the general public. In a move that could significantly reduce this risk, researchers at Rensselaer Polytechnic Institute have created a nanoscale coating for surgical equipment, hospital walls, and other surfaces which safely eradicates MRSA.

In a finding that could well revolutionize cooling technology as we know it, researchers at Oregon State University and the Pacific Northwest National Laboratory have discovered a way to achieve near-optimal heat dissipation by applying a nanostructured coating. Because of performance, versatility and economy of materials used, their method could soon lead to better electronics, heating and air conditioning. Read More
Diamonds aren’t just a girl’s best friend - they also boast outstanding physical properties that makes them an ideal material for industrial applications such as cutting and polishing. It is extraordinarily hard, conducts heat well and is practically inert to chemical substances. Ceramics – particularly high-performance ceramics – are likewise able to demonstrate special qualities. They are robust and withstands high temperatures. Researchers have now created a diamond coated ceramics composite material that combines the best of both materials. Read More
Yep, you read it right, spray-on glass. It could revolutionize the fields of agriculture, medicine, fashion, transportation - really, it would be easier to list where it might not be applicable. The remarkable product, called Liquid Glass, was developed by the German nano-tech firm Nanopool GmbH. Their patented process, known as “SiO2 ultra thin layering” involves extracting silica molecules from quartz sand, adding them to water or ethanol, and then... well, they won’t tell us what they do next, but the end result is a 100 nanometer-thick, clear, flexible, breathable coating that can be applied to almost any surface. We’re told that there are no added nano-particles, resins or additives - the coating is formed using quantum forces. The possible uses are endless. Read More
Already regarded as a “wonder fabric” for its lightness, softness, warmth even when wet, and other qualities, scientists from China say they have been able to improve on the natural properties of wool. They say their discovery could give wool a “brain,” placing it among other “smart” fabrics that shake off wrinkles, shrinkage and “breathe” to release perspiration. Read More
Nothing ruins a motorcycle trip like the smell of burning nylon and the sight of your possessions scattered across the highway. Soft-sided panniers are great when you want to pack some gear for a weekend getaway, but they’re not so great if they come into contact with your bike’s hot exhaust pipe. By applying a Zircotec ceramic coating to your bike’s exhaust system, the manufacturer says you can get rid of the heat shields and protect your panniers (and passenger!) from heat damage. Read More
