Breakthrough in ‘Spintronics’ Could Lead to Energy Efficient Chips

December 8, 2009

University of Twente and FOM Foundation researchers have succeeded in transferring magnetic information directly into a semiconductor at room temperature via a layer of aluminum oxide less than one namometer thick, bringing spintronics* within reach.

The main advantage of spintronics technology is reduced heat and power consumption in chips.

* Unlike conventional electronics, which employs the charge of the electron and its transport, spintronics exploits another important property… read more

Researchers at the California Institute of Technology and the University of California, San Diego have discovered a way to prevent light signals on a silicon chip from reflecting backwards and interfering with its operation.

Otherwise, the light beams would interfere with lasers and other photonic components on the chip and make the chip unstable. The breakthrough marks a significant achievement in the development of integrated photonic chips that could… read more

Breakthrough in optical quantum computing: 60 qubits

July 20, 2011

Physicists at the University of Virginia’s College of Arts & Sciences have demonstrated a breakthrough in the creation of massive numbers of entangled qubits — more precisely, a multilevel variant called “Qmodes.”

The physicists used an optical parametric oscillator (a laser) that emits entangled quantum electromagnetic fields (the Qmodes) over a rainbow of equally spaced colors called an “optical frequency comb.” Ultrastable lasers emitting over… read more

Yale Institute for Nanoscience and Quantum Engineering engineers have developed a novel approach to synthesizing nanowires using wet-etch lithography on commercially available silicon-on-insulator wafers.

This allows for direct integration of nanowires with microelectronic systems for the first time.

It also allows for them to act as highly sensitive biomolecule detectors that could revolutionize biological diagnostic applications, according to a report in Nature.

Breakthrough In Industrial-scale Nanotube Processing

November 3, 2009

Rice University scientists have unveiled a method for high-throughput industrial-scale processing of carbon-nanotube fibers, using chlorosulfonic acid as a solvent.

The process that could lead to revolutionary advances in materials science, power distribution and nanoelectronics.

Researchers have developed a new method that can look at a specific segment of DNA and pinpoint a single mutation, which could help diagnose and treat diseases such as cancer and tuberculosis.

Modern genomics has shown that just one mutation can be the difference between successfully treating a disease and having it spread rampantly throughout the body.

These small mutations can be the root of a… read more

Breakthrough in 3-D Brain Mapping Enables Removal of Fist-Sized Tumor

July 15, 2009

A new technology involving the fusion of four different types of images into a 3-D map of a patient’s brain has helped University of Cincinnati (UC) specialists successfully remove a fist-sized tumor from a brain.

The multiple brain scans from MRI, fMRI, diffusion tensor imaging, and computed tomography angiography were fused and installed into a surgical guidance computer. By revealing the tumor’s relationship to all of the functional centers,… read more

Breakthrough gives 3-D vision of life’s dawn

SRXTM scanning shows the interior or fossil embryos

A new technique allowing virtual dissections of half-billion-year-old fossil embryos is producing the first three-dimensional images of the dawn of life.

Synchroton-radiation X-ray tomographic microscopy, or SRXTM, leaves the tiny fossils untouched (compared to the conventional use of acid) but gives graphic details of their structure.

Breakthrough for quantum measurement

November 23, 2005

Two teams of physicists have measured the capacitance of a Josephson junction for the first time. The methods could be used to measure the state of quantum bits in a quantum computer without disturbing the state.

Breakthrough for carbon nanotube materials

September 30, 2008

CSIRO (Commonwealth Scientific and Industrial Research Organisation) and the NanoTech Institute of the University of Texas at Dallas have achieved a major breakthrough in the development of a commercially viable manufacturing process for large sheets of a range of materials made from carbon nanotubes.

They demonstrated that synthetically made carbon nanotubes can be commercially manufactured into transparent sheets that are stronger than steel sheets of the same weight.… read more

Breakthrough Flu Drug Might Already Exist

December 8, 2009

Researchers at the University of California at San Diego have identified a new molecular target for influenza drugs and have also found drugs already approved by the U.S. Food and Drug Administration that just might perfectly hit the target (neuraminidase, one of two major proteins present on the surface of the influenza virust that allows newly replicated viruses to be released into their host).

Breakthrough Chip Technology Lights the Path to Exascale Computing

December 2, 2010

IBM CMOS Integrated Nanophotonics (IBM)

IBM scientists Wednesday unveiled a new chip technology that integrates electrical and optical devices on the same piece of silicon, enabling computer chips to communicate using pulses of light (instead of electrical signals), resulting in smaller, faster and more power-efficient chips than is possible with conventional technologies.

The new technology, called CMOS Integrated Silicon Nanophotonics, is the result of a decade of development at IBM’s global Research laboratories.… read more
