Researcher Bing Hu paints a small square of ordinary paper with an ink that will deposit n...

By dipping an ordinary piece of paper into ink infused with carbon nanotubes and silver nanowires, scientists have been able to create a low-cost battery or supercapacitor that is ultra-lightweight, bendable and very durable. The paper can be crumpled, folded or even soaked in acidic or basic solutions and still will work.  Read More

After 24 hours, the cancer cells have taken up chimeric polypeptide-chemo combination (sho...

Blood vessels that supply tumors are more porous than normal vessels, makes nanoscale drug delivery systems a particularly attractive prospect. If properly engineered, nanoparticles can in fact get inside a tumor, targeting it precisely and allowing much higher drug dosages as they reduce side effects to a minimum. Two recent studies featured in the latest issue of the journal Nature Materials specifically address these issues and give us promising leads in the fight against cancer.  Read More

Roads covered in ice can be difficult and dangerous to drive on

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.  Read More

Vitraglyphic allows for much faster and cheaper manufacturing of high-precision glass prot...

A team of engineers and artists at the University of Washington's Solheim Rapid Manufacturing Laboratory has revived an ancient Egyptian glass casting method and developed "Vitraglyphic," a technique to manufacture glass objects from fine glass powder using computer-aided design and a 3-D printer, paving the way for a significantly faster and cheaper method for artists, architects and designers to build high-precision prototypes.  Read More

The humble lotus leaf continues to inspire the scientific world

Finding inspiration from nature in order to refine and advance modern technologies is nothing new; Mercedes’ bionic car was an interesting example and we’ve also seen a new ‘smart fabric’ based on the design of pine cones. Perhaps one of the most inspiring species, certainly in the plant world, is the lotus, which has already contributed to the development of fog-free windscreens and other surfaces along with improving the efficiency of solar cells. Now NASA is looking to the Lotus Leaf to develop a non-stick surface for use on spaceflight equipment.  Read More

Researchers believe nanoparticles hold the promise of battling cancer without the damaging side effects of chemotherapy or radiation treatment. They have discovered that coating minuscule balls of iron oxide with sugar molecules not only makes them particularly attractive to resource-hungry cancer cells, it also makes them more effective by allowing them to get close to each other, but not too close to render treatment ineffective.  Read More

A new polymer coating has been designed to protect historic buildings from graffiti while ...

Graffiti is not only ugly, it costs society millions of dollars to remove it. But graffiti on historic landmarks is worse because it often can't be removed using basic caustic solutions without damage to the underlying surface. Now a new, breathable coating could help preserve some of our most beautiful and priceless links to the past by providing them with an efficient, all-round protection against attacks by taggers.  Read More

Algae blooms are unpleasant and unpredictable phenomena that arise quickly and strike seas and oceans, often causing serious problems to local ecosystems. But, in an effort to try and find a use for such algae, a research team from Uppsala University, Sweden, has recently managed to design a record-breaking "green" lightweight battery that is incredibly easy to produce and might just even out the environmental consequences of these blooms.  Read More

Scientists are studying better ways of creating touch screen coatings that resist glare an...

Big touch screens, like those used on smart phones and portable media devices, are great … unless the sun is out. Then the glare can be a killer, rendering some devices next to useless. Scientists have developed a test for analyzing reflection-resistant coatings to make using touch screen devices easier. The research also includes defining a better smudge-resistant coating to deter ugly fingerprints and scratches from screens and surfaces.  Read More

The nano-capsules in the electroplated layer contain a fluid that is released if the layer...

Human skin has an amazing capacity to heal itself from scratches and cuts, so it’s not surprising that scientists are looking at transferring the self-healing properties of skin to industrial materials. Efforts to embed tiny liquid-filled capsules that rupture when a scratch occurs to spill healing agents into the damaged area of electroplated coatings have previously been hampered by the size of these capsules. But now researchers have developed a process for producing electroplated layers with nano-capsules that measure only a few hundred nanometers in diameter that could solve the problem.  Read More
