A nearly $2 million grant at the University of California, Riverside is being put to use in making silicon-based electronics obsolete. The new approach will depend on the development of a magnetologic gate, a transistor replacement that is built with graphene.
Rice University physicists have created a tiny "electron superhighway" that could one day be useful for building a quantum computer. The physicists described a new method for making a tiny device called a "quantum spin Hall topological insulator", which is one of the building blocks needed to create quantum particles that store and manipulate data.
Researchers led by Massachusetts Institute of Technology professor Daniel Nocera have produced something they're calling an "artificial leaf". Like living leaves, the device can turn the energy of sunlight directly into a chemical fuel that can be stored and used later as an energy source.
Researchers from the University of Toronto, King Abdullah University of Science & Technology, and Pennsylvania State University have created the most efficient colloidal quantum dot (CQD) solar cell ever.
By heating metal to make graphene, Rice University researchers may warm the hearts of high-tech electronics manufacturers. The lab of Rice chemist James Tour published two papers that advance the science of making high-quality, bilayer graphene. They show how to grow it on a functional substrate by first having it diffuse into a layer of nickel.
Researchers at Rensselaer Polytechnic Institute developed a new method for creating a layer of gold nanoparticles that measures only billionths of a meter thick. These self-assembling gold coatings with features measuring less than 10 nm could hold important implications for nanoelectronics manufacturing.
Northwestern University scientists have developed new materials that can detect hard radiation, a very difficult thing to do. The method could lead to a handheld device for detecting nuclear weapons and materials, such as a "nuclear bomb in a suitcase" scenario.
Lawrence Berkeley National Laboratory researchers at the Molecular Foundry have unveiled a semiconductor nanocrystal coating material capable of controlling heat from the sun while remaining transparent. This system, the first to selectively control the amount of near infrared radiation transmitted, could add a critical energy-saving dimension to "smart window" coatings.
3M and IBM announced that the two companies plan to jointly develop the first adhesives that can be used to package semiconductors into densely stacked silicon "towers." The companies are aiming to create a new class of materials, which will make it possible to build, for the first time, commercial microprocessors composed of layers of up to 100 separate chips.
University of Florida researchers may help resolve the public debate over America's future light source of choice: Edison's incandescent bulb or the more energy efficient compact fluorescent lamp. It could be neither. Instead, America's future lighting needs may be supplied by a new breed of light-emitting diode, or LED, that conjures light from the invisible world of quantum dots.
Fiber optic technology is well-established for long-distance data transmission, but efforts to use photons in microcircuits have been hampered the tendency for materials defects to deflect the signal. A new type of circuit component now allows photons to find their around these defects.
A net of fine lines surrounding tiny silica microspheres confined in thin liquid crystal layers is now a test bed for creating any kind of microscopic knot. The finding by researchers in Germany and Slovenia could have important implications because the knotting of DNA molecules is crucial to the way genes function.
Hewlett-Packard plans to spin off its personal computer division into a separate business, according to unnamed sources in major news outlets. It marks a reversal from HP's previous stance, in March, when it denied this rumor.
A team led by researchers at Stanford and Harvard universities has not only created a new material for high-speed organic semiconductors, it has come up with a new approach that can take months, even years, off the development timeline.
A team of researchers Argonne National Laboratory has built a multi-thousand-layer lens that focuses high-energy x-rays so tightly it can detect objects as small as 15 nm in size and is in principle capable of focusing to well below 10 nm.
The editors of R&D Magazine have opened the nominations for the 2012 R&D 100 Awards competition, which will celebrate the 50th anniversary of the awards. If your organization introduced a new product this year, or is planning to, you can begin the entry process now.
Two Lehigh University physicists have developed an imaging technique that makes it possible to directly observe light-emitting excitons as they diffuse in a new material that is being explored for its extraordinary electronic properties. Called rubrene, it is one of a new generation of single-crystal organic semiconductors.
As demands grow for portable sensing equipment in the medical equipment and other sectors, instrument designers will demand better power efficiency from the electronic components they specify for their instruments. ON Semiconductor believes its Q32M210 family of mixed-signal microcontrollers will fill a niche for precision measurement and monitoring.
Cheap and readily available, silicon is an attractive choice for integrated photonic circuits. However, silicon suffers high optical loss, so researchers in Singapore have built a new chip that integrates, in addition to a laser, an optical grating that provides gain and steady output wavelengths.
Graphite oxide has been a target for supercapacitor development for up to a decade, but prior to a recent breakthrough at Rice University nobody had been able to turn the material into a functional supercapacitor without adding chemicals. The researchers discovered a new phenomenon of GO, and were able to make the transition simply using heat.
Renaissance architects demonstrated their understanding of geometry and physics when they built whispering galleries into their cathedrals. These circular chambers were designed to amplify and direct sound waves so that, when standing in the right spot, a whisper could be heard from across the room. Now, scientists at the University of Pennsylvania have applied the same principle on the nanoscale to reduce emission lifetime.
It stands to reason that the photovoltaic panels on a rooftop are not only converting sunlight to electricity, they are keeping the building cooler by intercepting the solar rays. Until recent research, however, just how much of a cooling benefit they can provide was not known.
Researchers from Tel Aviv University and the Hebrew University have demonstrated how semiconductor nanocrystals can be doped in order to change their electronic properties and be used as conductors, offering new possibilities for the design of small electronic and electro-optical devices.
Researchers at the Stanford School of Engineering have made a nanoelectronic synapse that might drive a new class of microchips that can learn, adapt, and make probability-based decisions in complex environments. The device emulates synaptic plasticity using phase-change material, and makes a leap past two-state transistors by demonstrating the ability to convey at least 100 values from each synapse.
Lawrence Berkeley National Laboratory researchers created tetrapod molecules of semiconductor nanocrystals and watched them break a fundamental principle of photoluminescence known as "Kasha’s rule." The discovery holds promise for multicolor light emission technologies, including LEDs.
