Scientists create artificial mother of pearl

By - July 26, 2012 1 Picture
Mother of pearl, also known as nacre, is the hard iridescent coating found on the outside of pearls, and the inside of certain mollusc’s shells. Besides being a nice-looking material used for jewelry and other types of ornamentation, it’s also remarkably strong. Now, scientists from the University of Cambridge have discovered how to make the stuff themselves. Read More

New coating technology promises self-cleaning cars

By - July 22, 2012 1 Picture
Nissan’s "Scratch Guard Coat” has been healing fine scratches on the company’s cars for a few years now, and the technology has also made its way into an iPhone case. More recent developments have produced coatings to heal more substantial scratches and scrapes using nano-capsules. Now researchers at The Netherlands’ Eindhoven University of Technology (TU/e) have developed a coating that is not only self-healing, but also promises to free car owners of the tiresome chore of washing the car.

Window coating improves mood by letting more light in

By - July 4, 2012 1 Picture
With many of us spending more and more time indoors, it can be a struggle to get the amount of sunlight our bodies crave. Modern heat-insulating, sun-protection glazing doesn’t help, as it reflects a noticeable percentage of the incident sunlight in the part of the spectrum that governs our hormonal balance. Researchers at the Fraunhofer Institute for Silicate Research (ISC) have developed a coating for windows that lets in more light, in particular those wavelengths of light that have a beneficial effect on our sense of well-being.

Selenium shows promise as antibiotic coating for medical devices

By - June 21, 2012 1 Picture
Although it’s known to kill bacteria, selenium has never been tried as an antibacterial coating for implanted medical devices ... until now, that is. Engineers from Rhode Island’s Brown University have applied coatings of selenium nanoparticles to pieces of polycarbonate – the material used for things like catheters and endotracheal tubes – and then exposed those samples to Staphylococcus aureus bacteria. In some cases, populations of the bacteria were subsequently reduced by up to 90 percent. Read More

Liquid and ice "SLIPS" off new ultra smooth surface

By - June 11, 2012 4 Pictures
Although advances in refrigeration technology means we don’t need to defrost the freezer as often as we used to, many of us are still forced to carry out the task on a regular basis lest we find the frosty walls closing in to claim that tub of ice cream. Now a team from Harvard University has developed ultra smooth slippery surfaces that prevent ice sheets from developing by allowing even tiny drops of condensation or frost to simply slide off. As well as keeping freezers frost-free, the technology could be used to prevent ice build up on metal surfaces in wind turbines, marine vessels, and aircraft. Read More

LiquiGlide coating means you'll never waste a drop of ketchup again

By - May 23, 2012 1 Picture
It's one of the most common and infuriating dining problems everyone encounters: getting ketchup to pour smoothly out of bottle and onto your plate. You've probably heard a number of solutions from "tap the 57" to "spin the bottle between your hands," but even those methods can still drown your fries in sauce in the end. Luckily, science - or rather, a research group working at MIT - has finally taken notice and concocted an impressive solution. By coating the inside of any bottle with the slippery LiquiGlide coating, anything from ketchup to mayonnaise to jam flows right out like water, barely leaving a smudge behind. Read More

Superbug-killing coating "magnetically" draws in bacteria

By - May 10, 2012 3 Pictures
Scientists at Singapore's Nanyang Technological University (NTU) have created a "magnetic-like" coating that traps and destroys 99 percent of the bacteria and fungi that it encounters. The antibacterial coating has been shown to be effective against superbugs like Staphylococcus aureus and is already being used in the manufacture of contact lenses. As well as finding numerous biomedical and household applications, the research could lead to new wound treatments and even be used to target bacterial infections inside the body without the use of conventional antibiotics.

Gold nanoparticles paint a precise picture of brain tumors before and during surgery

By - April 15, 2012 1 Picture
Scientists at Stanford University’s School of Medicine have created nanoparticles that are able to precisely highlight brain tumors. Because the nanoparticles can be imaged in three different ways, they can be used to delineate the boundaries of tumors before and during brain surgery to ease the complete removal of tumors. The scientists have already used the nanoparticles to remove brain tumors from mice with unprecedented accuracy and hope the technique could be used on humans in the future. Read More
