An innovative and inexpensive way of making nanomaterials on a large scale has resulted in novel forms of advanced materials that pave the way for exceptional and unexpected optical properties. The new fabrication technique, known as soft lithography, offers many significant advantages over existing techniques, including the ability to scale-up the manufacturing process to produce devices in large quantities.
The mobile world reaches its limits every time the power supply runs out. There must surely be huge market potential for devices that take their energy from the daylight just as effortlessly as we breathe oxygen from the air. Integrated solar modules can provide the solution. Integrated solar cells are already being used to power wrist watches and pocket calculators. But a significantly higher output is needed in order to feed power-hungry devices, such as cellphones or palmtops.
Crystal IS, Inc. of Green Island, NY has announced that it has won a $2M award from NIST's Advanced Technology Program (ATP) for the development of high performance deep ultraviolet (UV) light emitting diodes (LEDs) based on its low defect aluminum nitride (AlN) substrates. This award follows the recent successful completion of a previous ATP award to Crystal IS in 2004 for the development of 2-inch high quality AlN substrates.
A reflective flat-panel display that exhibits color tuning across the entire visible spectrum could be a valuable power saver.
The highest-resolution images ever seen in (S)TEM electron microscopy have been recorded using a new instrument developed jointly by U.S. Department of Energy national laboratories, FEI Company and CEOS GmbH, in Heidelberg, Germany.
U.S. scientists have developed a method of increasing the fluorescence intensity of quantum dots by a factor of at least 108.
Scientists have used near-infrared fluorescence microscopy to image carbon nanotubes inside a living organism for the first time.
An exotic molecule built from electrons and antimatter is being touted as a route to powerful gamma-ray lasers.
The deployment of space platforms that capture sunlight for beaming down electrical power to Earth is under review by the Pentagon, as a way to offer global energy and security benefits ¡V including the prospect of short-circuiting future resource wars between increasingly energy-starved nations.
Cancer-sensing devices built as cheaply and efficiently as wristwatches - using many of the same operating principles - could change the way clinicians detect, treat and monitor cancer in patients. Researchers from the Georgia Institute of Technology have created an acoustic sensor that can report the presence of small amounts of mesothelin, a molecule associated with a number of cancers including mesothelioma, as they attach to the sensor's surface.
