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.
Siemens Medical Solutions USA, Inc. and Xintek Inc. announce today that they have signed an agreement to establish a joint venture company in Research Triangle Park, N.C. The mission of the new company, named XinRay Systems, is to develop a new multi-pixel X-ray source technology for a broad range of diagnostic imaging applications.
By placing quantum dots on a specially designed photonic
crystal, researchers at the University of Illinois have
demonstrated enhanced fluorescence intensity by a factor of up to 108.
Potential applications include high-brightness light-emitting diodes,
optical switches and personalized, high-sensitivity biosensors.
BIOIDENT Technologies Inc., the leading
company in the development of printed opto-electronic solutions for life sciences, today
announced that the company is a co-winner in the semiconductor category for the
seventh annual Wall Street Journal contest for Technology Innovation. BIOIDENT was
awarded for the development of its PhotonicLab Platform™, which enables rapid in-vitro
diagnostics, chemical and biological threat detection, and environmental testing without
the need for off-site lab analysis.
Some new technologies appear from nowhere. Others are heralded by such long fanfares that it seems they will never arrive. Electronic paper is surely in the second category. The idea of a display screen that has the clarity and flexibility of paper has been around for at least a decade. It has found a few niche, black-and-white applications in mobile phones and ¡§electronic books¡¨. As a mass-market, full-colour product, however, it has conspicuously failed to show up.
