Water droplet networks could harvest water from fog

By - May 14, 2014 1 Picture
Harvesting water out of thin air, might seem like a pipe dream, but the air-stable water droplet networks, currently being developed by Oak Ridge National Laboratory (ORNL) researchers could prove to be a step in the right direction. Created with the aid of a new technique, these water droplet networks could also potentially find use in membrane research and biological sensing applications. Read More

Wear-resistant surfaces inspired by scorpions

By - January 26, 2012 1 Picture
As any graffiti-removal specialist will tell you, sand-blasting is definitely an effective method of removing substances that have bonded onto hard surfaces. Unfortunately, sand or other abrasive particles suspended in air or liquid also have a way of eroding not just spray paint, but pretty much anything they encounter. As a result, items such as helicopter rotor blades, airplane propellers, rocket motor nozzles and pipes regularly wear out and need to replaced. Interestingly enough, however, scorpions live their entire lives subjected to blowing sand, yet they never appear to ... well, to erode. A group of scientists recently set out to discover their secret, so it could be applied to man-made materials. Read More

Nanoscale coating for surgical equipment and hospital surfaces safely kills MRSA

By - August 16, 2010 2 Pictures
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.

Billionth-of-a-meter-thick gold layers created in ten minutes

By - June 21, 2010 2 Pictures
We’ve reported on some rather questionable products of gold plating technology before, including a gilded iPhone, Wii gaming system and barbecue. There are legitimate reasons to coat things in gold, however, such as in the production of nanoelectronics and semiconductors. The coatings used in these applications are infinitely thinner than what you would typically use on an iPhone, so it is of the utmost importance that they be as smooth and uniform as possible. Recently, researchers at Troy, New York’s Rensselaer Polytechnic Institute announced that they have devised a quick and simple method of producing just such coatings. Read More

Nanopool says the case is clear for spray-on glass

By - February 10, 2010 2 Pictures
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

Philips offers new e-ink possibilities in color

By - December 14, 2009 4 Pictures
Rather than using e-paper technology just for displays, the research arm of Dutch technology company Philips Electronics has developed a relatively cheap, light, thin and energy efficient means of turning the whole of the surface of a device into a digital canvas. E-skin technology could be used to change the color of a mobile phone when a call comes in, alter the appearance of a kettle when the water is boiling or even be applied to wallpaper so you can redecorate your room at the flick of a switch.

Nano-particle coating prevents ice buildup on roads and power lines

By - October 30, 2009 2 Pictures
Like most things, ice can be a blessing or a burden depending on the circumstances. It’s perfect crushed in a drink on a hot summer’s day, but can wreak havoc when it collects on roads, power lines and aircraft in freezing temperatures. A University of Pittsburgh-led team has found a way to reduce these dangers by developing a nanoparticle-based coating that can be easily applied to impede the buildup of ice on solid surfaces.
