The Semiconductor Devices of the Future
When physicists sandwiched together different types of semiconductor to create the first transistor in 1947, they made bulky vacuum valves obsolete and so revolutionised the electronics industry. Since then researchers have been pushing the boundaries of semiconductor technology hoping for another revolution. At the 26th International Conference... view more... (2002-07-23)
Transforming Nanowires Into Nano-Tools Using Cation Exchange Reactions
A team of engineers from the University of Pennsylvania has transformed simple nanowires into reconfigurable materials and circuits, demonstrating a novel, self-assembling method for chemically creating nanoscale structures that are not possible to grow or obtain otherwise. view more (2009-10-26)
Delft researchers predict 'nanobattery' performance
Researchers at Delft University of Technology can predict how nanostructuring - the extreme reduction of structure - will affect the performance of Li-ion batteries. view more (2007-04-03)
Building better bone replacements with bacteria
Bacteria that manufacture hydroxyapatite (HA) could be used to make stronger, more durable bone implants. Professor Lynne Macaskie from the University of Birmingham this week (7-10 September) presented work to the Society for General Microbiology's meeting at Heriot-Watt University, Edinburgh. view more (2009-09-08)
Pitt researchers harness carbon nanomaterials for drug delivery systems, oxygen sensors
Two nanoscale devices recently reported by University of Pittsburgh researchers in two separate journals harness the potential of carbon nanomaterials to enhance technologies for drug or imaging agent delivery and energy storage systems, in one case, and, in the other, bolster the sensitivity of oxygen sensors essential in confined settings, from... view more...

Nanoscience Study Shows That Quantum Dots "Talk"
Scientists who hope to use quantum dots as the building blocks for the next generation of computers have found a way to make these artificial atoms communicate. view more (2006-02-22)
JILA solves problem of quantum dot 'blinking'
Quantum dots-tiny, intense, tunable sources of colorful light-are illuminating new opportunities in biomedical research, cryptography and other fields. But these semiconductor nanocrystals also have a secret problem, a kind of nervous tic. They mysteriously tend to "blink" on and off like Christmas tree lights, which can reduce their... view more...

Turning Sunlight into Liquid Fuels: Berkeley Lab Researchers Create a Nano-sized Photocatalyst for Artificial Photosynthesis
For millions of years, green plants have employed photosynthesis to capture energy from sunlight and convert it into electrochemical energy. A goal of scientists has been to develop an artificial version of photosynthesis that can be used to produce liquid fuels from carbon dioxide and water. view more (2009-03-11)
Finding by Rice University chemists could aid development of new nanodevices
Rice University chemists have discovered that tiny building blocks known as gold nanorods spontaneously assemble themselves into ring-like superstructures. view more (2007-03-12)

Argonne researcher studies what makes quantum dots blink
In order to learn more about the origins of quantum dot blinking, researchers from the U.S. Department of Energy's Argonne National Laboratory, the University of Chicago and the California Institute of Technology have developed a method to characterize it on faster time scales than have previously been accessed. view more (2007-10-05)
'Strained' quantum dots show new optical properties
Quantum dots, tiny luminescent particles made of semiconductors, hold promise for detecting and treating cancer earlier. However, if doctors were to use them in humans, quantum dots could have limitations related to their size and possible toxicity. view more (2008-12-08)
Using nano-magnets to enhance medical imaging
Nanoscale magnets in the form of iron-containing molecules might be used to improve the contrast between healthy and diseased tissue in magnetic resonance imaging (MRI)—as long as the concentration of nanomagnets is carefully managed. view more (2007-02-02)
Jet-propelled Imaging for an Ultrafast Light Source
John Spence, a physicist at Arizona State University, is a longtime user of the Advanced Light Source at Lawrence Berkeley National Laboratory, where he has contributed to major advances in lensless imaging. view more (2009-07-30)
Method slashes quantum dot costs by 80 percent
In an important advance toward the large-scale manufacture of fluorescent quantum dots, scientists at Rice University have developed a new method of replacing the pricey solvents used in quantum dot synthesis with cheaper oils that are commonplace at industrial chemical plants. view more (2005-09-08)
