Team of more than 20 researchers directed white blood cells containing the oxidizing enzyme "myeloperoxidase" to attack nanotubes, reducing their unhealthful effects and prompting natural biodegradation, says report in "Nature Nanotechnology" An international study based at the University of Pittsburgh provides the first identification of a human enzyme that can biodegrade carbon nanotubes-the superstrong materials found in products from electronics to plastics-and in laboratory tests offset...

A team of Swedish and American scientists has shown for the first time that carbon nanotubes can be broken down by an enzyme - myeloperoxidase (MPO) - found in white blood cells. Their discoveries are presented in Nature Nanotechnology and contradict what was previously believed, that carbon nanotubes are not broken down in the body or in nature. The scientists hope that this new understanding of how MPO converts carbon nanotubes into water and carbon dioxide can be of significance to...

A newly discovered path for the conversion of sunlight to electricity could brighten the future for photovoltaic technology. Researchers with Lawrence Berkeley National Laboratory (Berkeley Lab) have found a new mechanism by which the photovoltaic effect can take place in semiconductor thin-films. This new route to energy production overcomes the bandgap voltage limitation that continues to plague conventional solid-state solar cells. Working with bismuth ferrite, a ceramic made from bismuth,...

Researchers at the University of South Florida have developed a technique to turn defects in graphene into tiny metallic wires When most of us hear the word 'defect', we think of a problem that has to be solved. But a team of researchers at the University of South Florida (USF) created a new defect that just might be a solution to a growing challenge in the development of future electronic devices. The team lead by USF Professors Matthias Batzill and Ivan Oleynik, whose discovery was...

Self-powered nanosensors By combining a new generation of piezoelectric nanogenerators with two types of nanowire sensors, researchers have created what are believed to be the first self-powered nanometer-scale sensing devices that draw power from the conversion of mechanical energy. The new devices can measure the pH of liquids or detect the presence of ultraviolet light using electrical current produced from mechanical energy in the environment. Based on arrays containing as many as 20,000...

University of Florida engineering researchers have found they can ignite certain nanoparticles using a low-power laser, a development they say opens the door to a wave of new technologies in health care, computing and automotive design. A paper about the research appears in this week's advance online edition of Nature Nanotechnology. Vijay Krishna, Nathanael Stevens, Ben Koopman and Brij Moudgil say they used lasers not much more intense than those found in laser pointers to light up, heat or...

A collaborative research project has brought the world a step closer to producing a new material on which future nanotechnology could be based. Researchers across Europe, including the UK's National Physical Laboratory (NPL), have demonstrated how an incredible material, graphene, could hold the key to the future of high-speed electronics, such as micro-chips and touchscreen technology. Graphene has long shown potential, but has previously only been produced on a very small scale, limiting...
