Silicon chips for optical quantum technologies
A team of physicists and engineers has demonstrated exquisite control of single particles of light - photons - on a silicon chip to make a major advance towards the long sought after goal of a super-powerful quantum computer. view more (2008-03-28)
Chalmers first with integrated receiver for high frequency applications
As the first research group in the world, researchers at Chalmers have succeeded in combining a receiver for high frequencies with an antenna on a small chip. view more (2007-11-29)
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)
Molecular machines drive plasmonic nanoswitches
Plasmonics -- a possible replacement for current computing approaches -- may pave the way for the next generation of computers that operate faster and store more information than electronically-based systems and are smaller than optically-based systems, according to a Penn State engineer who has developed a plasmonic switch. view more (2009-02-12)
A First in Integrated Nanowire Sensor Circuitry
Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have created the world's first all-integrated sensor circuit based on nanowire arrays, combining light sensors and electronics made of different crystalline materials. Their method can be used to reproduce numerous such... view more... (2008-08-05)
U.S. patients get more for their money than NHS patients do
Some patients in the United States are getting better health care than NHS patients in Britain, for roughly the same cost, finds a study in this week's BMJ. view more (2002-01-16)
Neurons hard wired to tell left from right
It's well known that the left and right sides of the brain differ in many animal species and this is thought to influence cognitive performance and social behaviour. For instance, in humans, the left half of the brain is concerned with language processing whereas the right side is better at comprehending musical melody. view more (2008-03-31)
How can we make nanoscale capacitors even smaller?
Researchers at UC Santa Barbara have discovered what limits our ability to reduce the size of capacitors, often the largest components in integrated circuits, down to the nanoscale. view more (2006-10-13)
Ceramic microreactors developed for on-site hydrogen production
Scientists at the University of Illinois at Urbana-Champaign have designed and built ceramic microreactors for the on-site reforming of hydrocarbon fuels, such as propane, into hydrogen for use in fuel cells and other portable power sources. view more (2006-09-20)
Researchers create first nanofluidic transistor, the basis of future chemical processors
University of California, Berkeley, researchers have invented a variation on the standard electronic transistor, creating the first "nanofluidic" transistor that allows them to control the movement of ions through sub-microscopic, water-filled channels. view more (2005-06-30)
High-speed material for data transfer
It doesn’t add up: error-free data rapidly transmitted thousands of kilometers, but within the computer - a bottleneck. “Circuit boards and connectors are the limiting factor in computer processing speeds,” explains Dr. Michael Popall of the Fraunhofer Institute for Silicate Research ISC in Würzburg. With standard... view more... (2002-11-14)
Making a good impression: Nanoimprint lithography tests at NIST
In what should be good news for integrated circuit manufacturers, recent studies by the National Institute of Standards and Technology (NIST) have helped resolve two important questions about an emerging microcircuit manufacturing technology called nanoimprint lithography-yes, it can accurately stamp delicate insulating structures on advanced... view more...

Working together to design robust silicon chips
Designers of high-speed silicon chips have often had to compromise on performance levels for their integrated circuit designs because of physical weaknesses appearing during design verification or even in production. view more (2009-11-13)
Indelible watermarks
As the Internet extends its reach and grows in complexity, there is a greater need for digital watermarks in image, audio and video data. Using a similar technique to banknote watermarking, invisible or inaudible information is inserted into digital content to thwart unauthorized use and ensure that honest paying consumers receive the authentic... view more...

Autism problems explained in new research
New research from Melbourne's Howard Florey Institute helps to explain why children with autism spectrum disorders (autism) have problem-solving difficulties. view more (2005-10-25)
'Nanonet' circuits closer to making flexible electronics reality
Researchers have overcome a major obstacle in producing transistors from networks of carbon nanotubes, a technology that could make it possible to print circuits on plastic sheets for applications including flexible displays and an electronic skin to cover an entire aircraft to monitor crack formation. view more (2008-07-24)
Discovery Brings New Type of Fast Computers Closer to Reality
Physicists at UC San Diego have successfully created speedy integrated circuits with particles called "excitons" that operate at commercially cold temperatures, bringing the possibility of a new type of extremely fast computer based on excitons closer to reality. view more (2009-09-28)
UBC researchers put a new spin on electrons
In the first demonstration of its kind, researchers at the University of British Columbia have controlled the spin of electrons using a ballistic technique--bouncing electrons through a microscopic channel of precisely constructed, two-dimensional layer of semiconductor. view more (2009-04-16)
Emulating and testing chips
Even coffee machines will soon begin to "think" for themselves. There is at least a clear trend emerging to equip all kinds of electrical devices with chips that offer special functions. It takes a considerable amount of time to develop such ASICs - application-specific integrated circuits. "From establishing initial contact with... view more... (2002-11-27)
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)
