UNSW's ARC Photovoltaic Centre of Excellence has again asserted its leadership in solar cell technology by reporting the first silicon solar cell to achieve the milestone of 25 per cent effiency. view more (2008-10-23)
Researchers directly deposit gold nanoparticles in suspension
The delivery, manipulation and assembly of functional materials such as metal nanoparticles into predefined architectures and patterns is of great interest in nanotechnology. view more (2007-08-10)
Sweet nanotech batteries
Nanotechnology could improve the life of the lithium batteries used in portable devices, including laptop computers, mp3 players, and mobile phones. Research to be published in the Inderscience publication - International Journal of Nanomanufacturing - demonstrates that carbon nanotubes can prevent such batteries from losing their charge capacity... view more...

Growing glowing nanowires to light up the nanoworld
The nano world is getting brighter. Nanowires made of semiconductor materials are being used to make prototype lasers and light-emitting diodes with emission apertures roughly 100 nm in diameter-about 50 times narrower than conventional counterparts. view more (2006-05-26)
The End of the Line for Silicon Dioxide?
By means of computer simulations, scientists at the Technical Universities in Clausthal and Vienna are investigating new materials for even smaller and more efficient transistor generations. The smaller the transistors, the faster they can operate. As a result, faster and faster processors can also be designed. The function of a transistor... view more... (2003-12-23)
Testing, radiation testing: Northwestern transistors on space station
Transistors based on a new kind of material created by Northwestern University researchers have been lifted into outer space on the space shuttle Endeavour and attached to the outside of the International Space Station for radiation testing. view more (2008-06-11)
Researchers bend light through waveguides in colloidal crystals
Researchers at the University of Illinois are the first to achieve optical waveguiding of near-infrared light through features embedded in self-assembled, three-dimensional photonic crystals. view more (2008-01-08)
Tiny spectrometer offers precision laser calibration
A tiny device for calibrating or stabilizing precision lasers has been designed and demonstrated at the National Institute of Standards and Technology (NIST). view more (2007-05-14)
Silicon Thin-Film Solar Cells Gaining In Efficiency
An important goal of modern energy research is to directly convert sunlight into electricity at low cost. Silicon thin-film solar cells promise comparatively lower costs than conventional solar cells. However, to become a mass product of the future, the efficiencies of large-area modules must climb from currently about 6 to 7 percent to 10 percent... view more... (2002-08-08)
Caltech scientists first to trap light and sound vibrations together in nanocrystal
Researchers at the California Institute of Technology (Caltech) have created a nanoscale crystal device that, for the first time, allows scientists to confine both light and sound vibrations in the same tiny space. view more (2009-10-26)
Magnetic computer sensors may help study biomolecules
Magnetic switches like those in computers also might be used to manipulate individual strands of DNA for high-speed applications such as gene sequencing, experiments at the National Institute of Standards and Technology (NIST) suggest. view more (2007-05-11)
Hi-Fi failure helps to brighten beer
BRIGHTER, clearer beer could be on the way thanks to a superfine filter that owes its existence to the failure of a decade-old recording technology. In the early 1990s, Philips of the Netherlands developed the Digital Compact Cassette tape format, which was designed to give CD-quality sound on standard magnetic tapes. DCC used record/playback... view more... (2004-07-07)
Proteomics on a chip
'Golden approach' human proteine classification Proteomics on a chip Knowledge of the human proteome may provide us with even more insight than knowledge of DNA. This 'protein blueprint' of a human contains valuable information about cell properties and disease causes. A single cell, however, already consists of several thousands of proteines. To... view more... (2002-06-18)
Tiny 'Lab-on-a-Chip' Can Detect Pollutants, Disease and Biological Weapons
For centuries, animals have been our first line of defense against toxins. A canary in a coalmine served as a living monitor for poisonous gases. Scientists used fish to test for contaminants in our water. Even with modern advances, though, it can take days to detect a fatal chemical or organism. view more (2009-02-18)
People only eat 1 when the chips are brown
Dr. Don Henne isn't wasting his degree when he's standing by the deep fryer waiting for potato slices to turn brown. He's conducting research that will help the potato industry and consumers. view more (2008-07-17)
NPL research shows there could be no end in sight for Moore's Law
The fast pace of growing computing power could be sustained for many years to come thanks to new research from the UK's National Physical Laboratory (NPL) that is applying advanced techniques to magnetic semiconductors. view more (2008-12-09)
Toward cheaper imaging systems for identifying concealed weapons on the human body
Electrical engineers from UC San Diego have created high-performance W-Band silicon-germanium (SiGe) radio frequency integrated circuits (RFICs) for passive millimeter-wave imaging. view more (2009-06-09)
Speed bumps less important than potholes for graphene
For electrical charges racing through an atom-thick sheet of graphene, occasional hills and valleys are no big deal, but the potholes-single-atom defects in the crystal-they're killers. view more (2007-07-13)
Microchip fingerprints used to lock out chip pirates
Pirated microchips -- chips stolen from legitimate factories or made from stolen blueprints -- account for billions of dollars in annual losses to chipmakers. view more (2008-03-12)
Make your own microfluidic device with new kit from U-M
A type of device called a "lab-on-a-chip" could bring a new generation of instant home tests for illnesses, food contaminants and toxic gases. But today these portable, efficient tools are often stuck in the lab themselves. Specifically, in the labs of researchers who know how to make them from scratch. view more (2008-07-25)
