New self-cleaning paint stands up to wear and tear

How would you like to be able to wash your car by just hosing it off – no soap, scrubbing or drying? You may be able to in the not-too-distant future, thanks to research being led by a team at University College London. Drawing on earlier research, they've developed an ultra-hydrophobic (water-repelling) paint that can be applied to a variety of surfaces, and that stays on once applied. Read More

Panasonic’s new technology purifies water with sunlight and photocatalysts

Drinking clean water is something that many people in the world can't take for granted, as they rely on polluted sources and often have no access to purification systems. In response to that problem, Panasonic is developing a new technology that looks to the sun to clean water extracted from the ground. The company recently presented a system that uses sunlight and photocatalysts to purify polluted water at a high reaction rate, to improve access to clean water where it's needed. Read More

New Li-ion anode achieves 70 percent charge in just two minutes

Researchers at the Nanyang Technological University (NTU) in Singapore have developed a new, proof-of-concept anode for lithium-ion batteries that can charge to 70 percent of its capacity in only two minutes and has a very long lifespan of ten thousands charge/discharge cycles. The advance could lead to the production of high-rate lithium-ion batteries, with interesting implications for personal electronics and, perhaps, even electric vehicles.Read More

"Microscopic shag carpet" may help bones bond with implants

Like a lot of things, bone cells grow and reproduce quicker on textured surfaces than on smooth ones. With that in mind, a team of scientists from Ohio State University are developing a new coating that could allow implants such as artificial hips to bond with bones faster. That coating is described as “a microscopic shag carpet made of tiny metal oxide wires.” Read More

UCL research flips the script on self-cleaning materials

In what they're calling a breakthrough discovery, UCL researchers studying the properties of titanium dioxide catalysts, which are widely used in self-cleaning products and materials, claim to have challenged the accepted view of how mixed-phase samples of the material actually behave.Read More

Multi-use Titanium Dioxide claimed to be the next "wonder material"

Graphene could soon be facing some competition for the unofficial title of “World’s Most Useful New Substance.” Led by Associate Professor Darren Sun, a team of scientists at Singapore’s Nanyang Technological University have spent the past five years developing a material known as Multi-use Titanium Dioxide. Their research indicates that it can be used to produce hydrogen and clean water from wastewater, double the lifespan of batteries, create antibacterial wound dressings ... and more. Read More

NASA-developed Airocide tech cleans household air

Some time ago, astronauts on the International Space Station needed a way to eliminate the ethylene gas that was being produced by plants growing aboard the station. NASA collaborated with the University of Wisconsin, and the result was an air-purifying system known as Airocide. Flash forward to the present, and that technology has been licensed for use in a household product that reportedly eliminates all sorts of airborne nasties. Read More

Liquid laundry additive turns clothes into air purifiers

A laundry additive created by researchers from the University of Sheffield and the London College of Fashion turns clothing into a photocatalytic material that can help remove nitrogen oxides (NOx) from the air. One of the most prominent air pollutants, nitrogen oxides are emitted from the exhausts of ICE-powered vehicles and aggravate asthma and other respiratory diseases. The researchers claim one person getting around town in clothing treated with the additive for a day would be able to remove roughly the same amount of nitrogen oxides produced by the average family car each day.Read More

Add a dash of titanium dioxide for self-cleaning walls, displays and garden furniture

For many people, the onset of warmer weather can mean pulling out the ol' scrubbing brush and getting to work on the slimy film of moss, algae, fungi and bacteria that has built up on the garden furniture over the colder months. But we may soon be able to say goodbye to this tiresome chore thanks to researchers at Fraunhofer who are developing coatings that would be activated by the sun’s rays to destroy organic substances attaching themselves to various surfaces.Read More
