Safer nanoparticles spotlight tumors, deliver drugs
Small is promising when it comes to illuminating tiny tumors or precisely delivering drugs, but many worry about the safety of nano-scale materials. Now a team of scientists has created miniscule flakes of silicon that glow brightly, last long enough to slowly release cancer drugs, then break down into harmless by-products. view more (2009-02-23)
Researchers achieve long-sought goal of using lasers to break specific molecular bonds

UCR physicist demonstrates how light can be used to remotely operate micromachines
A research team led by Umar Mohideen, a physicist at the University of California, Riverside, has demonstrated in the laboratory that the Casimir force - the small attractive force that acts between two close parallel uncharged conducting plates - can be changed using a beam of light, making the remote operation of micromachines a possibility. view more (2007-06-01)
Boosting the power of solar cells
New ways of squeezing out greater efficiency from solar photovoltaic cells are emerging from computer simulations and lab tests conducted by a team of physicists and engineers at MIT. view more (2008-11-25)
New 'finFET' promising for smaller transistors, more powerful chips
Purdue University researchers are making progress in developing a new type of transistor that uses a finlike structure instead of the conventional flat design, possibly enabling engineers to create faster and more compact circuits and computer chips. view more (2009-11-11)
New graphene transistor promises life after death of silicon chip
Researchers have used the world's thinnest material to create the world's smallest transistor - a breakthrough that could spark the development of a new type of super-fast computer chip. view more (2007-03-01)
NIST team proves bridge from conventional to molecular electronics possible
Researchers at the National Institute of Standards and Technology (NIST) have set the stage for building the "evolutionary link" between the microelectronics of today built from semiconductor compounds and future generations of devices made largely from complex organic molecules. view more (2008-03-19)
Unique Quantum Effect Found in Silicon Nanocrystals
Researchers at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL), collaborating with Innovalight, Inc., have shown that a new and important effect called Multiple Exciton Generation (MEG) occurs efficiently in silicon nanocrystals. MEG results in the formation of more than one electron per absorbed photon. view more (2007-07-26)
Catching waves: Measuring self-assembly in action
By making careful observations of the growth of a layer of molecules as they gradually cover the surface of a small silicon rectangle, researchers from the National Institute of Standards and Technology (NIST) and North Carolina State University (NCSU) have gained basic insights into how self-propagating self-assembly wave fronts develop and have... view more...

Press Invitation: Imperial College Centre for Electronic Materials and Devices Open Day
The Centre was established in October 1997 and encompasses the research activities in electronic materials and devices which are currently being pursued in various departments of the College. view more (1999-04-18)
MIT 'optics on a chip' may revolutionize telecom, computing
In work that could lead to completely new devices, systems and applications in computing and telecommunications, MIT researchers are bringing the long-sought goal of "optics on a chip" one step closer to market. view more (2007-02-06)
UC Riverside physicists contribute to state-of-the-art detector installed in Switzerland
UC Riverside scientists led by Gail Hanson, a distinguished professor of physics, are part of a collaboration of approximately 2300 international physicists who announced Dec. 19 that the world's largest silicon tracking detector at CERN in Geneva, Switzerland, had been successfully installed. view more (2007-12-21)
Stanford innovation helps 'enlighten' silicon chips
Light can carry data at much higher rates than electricity, but it has always been too expensive and difficult to use light to transmit data among silicon chips in electronic devices. view more (2005-10-27)
New infrared tool measures silicon wafer thickness
In the last few years, semiconductor circuit features have shrunk to sub-100 nanometer (nm) dimensions, while the size of the thin silicon wafers that these circuits are constructed on has grown from 200 millimeters (mm) to 300 mm (about 12 inches). The payoff is a higher yield of finished devices from fewer wafers. view more (2005-07-15)
Scientists demonstrate method for integrating nanowire devices directly onto silicon
Applied scientists at Harvard University in collaboration with researchers from the German universities of Jena, Gottingen, and Bremen, have developed a new technique for fabricating nanowire photonic and electronic integrated circuits that may one day be suitable for high-volume commercial production. view more (2008-05-09)
Beautiful diatoms: pattern for stable construction
AWI publication in 'Nature' Scientists from the Alfred Wegener Institute (AWI) published new results concerning the structure and material properties of diatoms in the science journal "Nature" on 20th february 2003 (Nature 421: 841-843). These single-celled marine algae are responsible for the majority of oxygen and biomass production in the... view more... (2003-02-21)
Solvents in Retreat
A new catalyst for selective solvent-free hydrogenation at low temperatures A number of cyclic hydrocarbons with multiple double bonds are readily accessible intermediates in chemical industry. In the course of further processing it is often necessary to saturate some of the double bonds with hydrogen to form single bonds. This type of reaction,... view more... (2001-03-27)
Microscopic sea creatures provide foundation for gas sensors and other devices
The three-dimensional shells of tiny ocean creatures could provide the foundation for novel electronic devices, including gas sensors able to detect pollution faster and more efficiently than conventional devices. view more (2007-03-12)
Rolling wires
Rolls which shape metal strip and wire become worn over the course of time. Rolls made of silicon nitride are more durable than those made of steel. Research engineers conduct work on the measurement, simulation and optimization of sintering and rolling processes. Throughout the world, wire is not only produced by drawing, but in many cases it is... view more... (2002-03-05)
Nanopowder Consisting Of Identical Particles
High-quality nanopowders made of refractory ceramics are a rare and very expensive material. All known methods of their manufacturing face the same problems - scanty quantities, extensive variety of particle sizes and expensive production. Researchers from the town of Tomsk have invented and manufactured a device to produce a choice selection of... view more... (2004-03-26)
