High Value Semiconducting Carbon Nanotubes
Moore's Law states that the number of transistors on a chip doubles every eighteen months. However current silicon technologies are approaching the limits imposed by quantum mechanics, which will stop Moore's Law in its tracks within 20 years. New materials and techniques must be found to complement and increase the capabilities of the current... view more... (2004-07-09)
ETH Zurich Develops a Single-chip Microsensor System to Analyse Gases
There are many target application areas envisaged for the gas sensor chip. Air quality in closed rooms can be monitored. The presence of dangerous - even poisonous - substances in the air can be detected, such as benzene from petrol pumps or perchloroethylene from dry-cleaning installations, and warnings can then be issued. Low-cost Mass... view more... (2001-11-14)
Manipulating light on a chip for quantum technologies
A team of physicists and engineers at Bristol University has demonstrated exquisite control of single particles of light - photons - on a silicon chip to make a major advance towards long-sought-after quantum technologies, including super-powerful quantum computers and ultra-precise measurements. view more (2009-06-09)
On chip separation: large molecules pass the speed camera first
What molecule or particle passes the finishline first? A good way to split a fluid sample into its separate parts is: organize a contest in a micro-channel. The largest parts will pass the optical detector first, the smaller ones follow at short distance. This principle of 'hydrodynamic chromatography' is now also possible on a chip. 'On-chip'... view more... (2002-12-10)
Nose-on-a-chip Aims To Mimic The Real Thing
An ambitious project is underway to build the world's smallest electronic nose. If the project succeeds, it is expected that the technology would have many potential applications in areas such as environmental monitoring, healthcare and food safety. The aim is to combine the odour sensors together with the signal processing components on to a... view more... (2002-03-04)
Cool Findings: Nanotubes Could Improve Thermal Management in Electronics
As the electronics industry continues to churn out smaller and slimmer portable devices, manufacturers have been challenged to find new ways to combat the persistent problem of thermal management. view more (2007-03-30)
Researchers generate high-speed pulses of laser light on silicon, speeding data transmission
In the Sept. 3 issue of Optical Society of America's Optics Express, published online today, researchers announce that they have built the world's first "mode-locked silicon evanescent laser." view more (2007-08-22)
MIT develops 'tractor beam' for cells, more
In a feat that seems like something out of a microscopic version of Star Trek, MIT researchers have found a way to use a "tractor beam" of light to pick up, hold, and move around individual cells and other objects on the surface of a microchip. view more (2007-10-31)
New material for nanoscale-computer chips
New data from Chinese-Danish collaboration shows that organic nanoscale wires could be an alternative to silicon in computer chips. The discovery has just been published in the respected scientific journal, Advanced Materials. view more (2009-08-17)
New technique could dramatically lower costs of DNA sequencing
Using computer simulations, researchers at the University of Illinois have demonstrated a strategy for sequencing DNA by driving the molecule back and forth through a nanopore capacitor in a semiconductor chip. The technique could lead to a device that would read human genomes quickly and affordably. view more (2007-12-13)
Move over, silicon: Advances pave way for powerful carbon-based electronics
Bypassing decades-old conventions in making computer chips, Princeton engineers developed a novel way to replace silicon with carbon on large surfaces, clearing the way for new generations of faster, more powerful cell phones, computers and other electronics. view more (2007-12-19)
Researchers create a broadband light amplifier on a chip
Cornell researchers have created a broadband light amplifier on a silicon chip, a major breakthrough in the quest to create photonic microchips. In such microchips, beams of light traveling through microscopic waveguides will replace electric currents traveling through microscopic wires. view more (2006-07-07)
High-pressure chemistry in ultra small pressure cooker
Small, clever process technology is essential for the future, but is it possible? Dutch-sponsored researcher Fernando Benito López investigated the possibilities of the so-called lab-on-a-chip: microreactor chips in which chemical reactions can take place under (high) pressure. view more (2007-04-16)
NEW APPROACH TO MASK-MAKING COULD RESULT IN FASTER COMPUTER CHIPS
British scientists have developed a revolutionary way to fabricate photomasks - a crucial component used in the manufacture of silicon chips. The technique could solve one of the most pressing problems in chip design - how to create increasingly narrow lines on the silicon wafer that form the chip's circuitry. Smaller linewidths enable more... view more... (1999-04-08)
BIOTECHNICA 2003: At the Pulse of the Chip Lab
The clinical and industrial analytics as well as diagnostics show an increasing demand for more sensitive and more rapid detection methods using smallest sample volumes. Within the BMBF joint project "MODULAB" a „chip-based-lab" construction kit is developed in which all the necessary working steps can be performed in separate... view more... (2003-10-07)
Quantum computer chips now 1 step closer to reality
In the quest for smaller, faster computer chips, researchers are increasingly turning to quantum mechanics -- the exotic physics of the small. The problem: the manufacturing techniques required to make quantum devices have been equally exotic. That is, until now. view more (2009-10-16)
Silicon with afterburners: Process developed at Rice could be boon to electronics manufacturer
Scientists at Rice University and North Carolina State University have found a method of attaching molecules to semiconducting silicon that may help manufacturers reach beyond the current limits of Moore's Law as they make microprocessors both smaller and more powerful. view more (2009-07-24)
UCSB researchers develop hybrid silicon evanescent laser
In what promises to be an important advance, researchers at the University of California, Santa Barbara have developed a novel laser by bonding optical gain layers directly to a silicon laser cavity. view more (2005-11-16)
