Nanowire biocompatibility in the brain: So far so good
The biological safety of nanotechnology, in other words, how the body reacts to nanoparticles, is a hot topic. Researchers at Lund University in Sweden have managed for the first time to carry out successful experiments involving the injection of so-called 'nanowires.' view more (2009-10-23)
Nanogenerators convert mechanical energy to electricity for self-powered devices
Researchers have developed a new technique for powering nanometer-scale devices without the need for bulky energy sources such as batteries. view more (2006-04-14)
Scientists build 'magnetic semiconductors' one atom at a time
In a stride that could hasten the development of computer chips that both calculate and store data, a team of Princeton scientists has turned semiconductors into magnets by the precise placement of metal atoms within a material from which chips are made. view more (2006-07-28)
Nanoresearchers challenge dogma in protein transportation in cells
New data on signalling proteins, called G proteins, may prove important in fighting diseases such as cardiovascular, neurodegenerative disorders, and cancer. view more (2009-09-22)
Charging ahead: University of Houston team revealing secrets of electricity-producing materials
Much like humans, materials are capable of some pretty remarkable things when they're placed under pressure. In fact, under the right conditions, materials can even produce electricity. view more (2009-07-28)
Canadian research team reports major breakthrough in lithium battery technology
An NSERC-funded lab at the University Of Waterloo has laid the groundwork for a lithium battery that can store and deliver more than three times the power of conventional lithium ion batteries. view more (2009-05-19)
Turning Science Fiction Into Fact
In the future, our computers no longer crash as we try and download pictures that are too heavy in memory, our cars no longer pollute the atmosphere and cancer could be dealt with by a visit to the GP. Some of it, at least, will happen thanks to cutting edge research happening now at the University of Leicester Department of... view more... (2004-07-07)
Advance by chemists may lead to better displays on laptop computers, cell phones
UCLA chemists working at the nanoscale have developed a new, inexpensive means of forcing luminescent polymers to give off polarized light and of confining that light to produce polymer-based lasers. view more (2007-09-18)
Why Nanolayers Buckle when Microbeams Bend
High-strength, ultra-light and elastic carbon materials are commonly used in high-performance sports goods and modern aerospace technology-for example in tennis rackets, racing tyres, heat shields and even guitars. view more (2005-12-16)
Nanocrystals Reveal Activity Within Cells
Researchers at the U.S. Department of Energy's (DOE) Lawrence Berkeley National Laboratory have created bright, stable and bio-friendly nanocrystals that act as individual investigators of activity within a cell. view more (2009-06-17)
Penn Engineers Create Carbon Nanopipettes That Are Smaller Than Cells and Measure Electric Current
University of Pennsylvania engineers and physicians have developed a carbon nanopipette thousands of times thinner than a human hair that measures electric current and delivers fluids into cells. view more (2008-01-16)
Strengthening Fluids With Nanoparticles
Researchers at Rensselaer Polytechnic Institute have demonstrated that liquids embedded with nanoparticles show enhanced performance and stability when exposed to electric fields. The finding could lead to new types of miniature camera lenses, cell phone displays, and other microscale fluidic devices. view more (2008-02-20)
A giant step toward tiny functional nanowires
Carving a telephone pole is easy if you have the right tools, say a power saw and some large chisels. And with some much tinier tools you could even carve a design into a paper clip if you wanted to. But shrink your sights down to the nanoscale, to a nanowire that is 1,000 times smaller than the diameter of a paper clip, and you find there are no... view more... (2005-07-01)
Researchers measure carbon nanotube interaction
Carbon nanotubes have been employed for a variety of uses including composite materials, biosensors, nano-electronic circuits and membranes. view more (2007-10-17)
Imaging quantum entanglement
An international team including scientists from the London Centre for Nanotechnology (LCN) today publishes findings in the journal 'Proceedings of the National Academy of Sciences' (PNAS) demonstrating the dramatic effects of quantum mechanics in a simple magnet. view more (2007-09-24)
Breakthrough for the computer of tomorrow?
For the first time a material now exists that is not only a semiconductor but also exhibits exploitable magnetic properties at room temperature. Researchers at the Royal Institute of Technology (KTH) in Stockholm, Sweden, have taken the lead in an international race to find the technology of tomorrow. Today's computers process information using... view more... (2003-09-25)
Magnet Made Of Pure Carbon
All known magnets contain metals and so far scientists believed that non-metallic material could not behave like a strong magnet. However, at the end of 20th century, some organic substances with strong magnetic properties were found, but they were magnetic only at very low temperatures, just above liquid helium. It seemed impossible to obtain... view more... (2001-10-24)
Go Speed Racer! Revving up the world's fastest nanomotors
In a "major step" toward a practical energy source for powering tomorrow's nanomachines, researchers in Arizona report development of a new generation of sub-microscopic nanomotors that are up to 10 times more powerful than existing motors. Their study is scheduled for the May 27 issue of ACS Nano, a monthly journal. view more (2008-05-01)
Secrets behind high temperature superconductors revealed
Scientists from Queen Mary, University of London and the University of Fribourg (Switzerland) have found evidence that magnetism is involved in the mechanism behind high temperature superconductivity. view more (2009-02-23)
Tethered Molecules Act as Light-Driven Reversible Nanoswitches
The ability to see is based on molecules in the eye that flip from one conformation to another when exposed to visible light. view more (2008-06-24)
