Self-soldering nanotubes could replace silicon transistors for flexible electronics

November 27, 2013

Depiction of junction heating caused by current flow across resistive nanotube-nanotube junctions.’

University of Illinois researchers have developed a way to solder (connect) carbon nanotubes, which are too small for even the world’s tiniest soldering iron.

Researchers have been exploring using carbon nanotubes as transistors instead of traditional silicon, because they are easier to transport onto alternate substrates, such as thin sheets of plastic, for low-cost flexible electronics or flat-panel displays.

Carbon nanotubes are high-quality conductors, but creating single tubes… read more

Berkeley Lab scientists record first inside look at carbon-capture molecular structure

November 26, 2013

Mg-MOF-74 is an open metal site MOF whose porous crystalline structure could enable it to serve as a storage vessel for capturing and containing the carbon dioxide emitted from coal-burning power plants. (National Academy of Sciences)

Researchers with Lawrence Berkeley National Laboratory (Berkeley Lab) have recorded the first electronic structure observations of the adsorption of carbon dioxide inside a metal-organic framework (MOF).

The “Mg-MOF-74″ MOF’s porous crystalline structure could enable it to serve as a storage vessel for capturing and containing the carbon dioxide emitted from coal-burning power plants.

MOFs are molecular systems consisting of a metal oxide center surrounded by organic… read more

Steering toxic drug-filled nanoparticles to zap cancer, not healthy cells

November 26, 2013

Multifunctionalized drug-loaded nanoparticle

North­eastern researchers are developing sim­u­la­tion soft­ware called Mag­nasim to more accu­rately steer simulated drug-filled mag­netic nanopar­ti­cles to tumor masses where they can safely dis­charge their con­tents.

The drugs used to kill cancer cells are just as toxic to neigh­boring healthy cells, so researchers have long sought a drug delivery method that tar­gets only cancer cells, bypassing the healthy ones.

Func­tional Mag­netic Res­o­nance Imaging (fMRI) is being… read more

“Los Alamos’ RAPTOR telescopes in New Mexico and Hawaii received a very bright cosmic birth announcement for a black hole on April 27,” said astrophysicist Tom Vestrand, lead author of a paper n the journal Science Nov. 21 that highlights the unusual event.

“This was the burst of the century,” said Los Alamos co-author James Wren. “It’s the biggest, brightest one to happen in at least 20 years, and… read more

Ultrasound-released nanoparticles may help diabetics avoid the needle

November 25, 2013

New technique allows diabetics to control insulin release with an injectable nano-network and portable ultrasound device.

A new nanotechnology-based technique for regulating blood sugar in diabetics could give patients the ability to release insulin painlessly using a small ultrasound device, allowing them to go days between injections — rather than using needles to give themselves multiple insulin injections each day.

A patient who has type 1 or advanced type 2 diabetes needs additional insulin, a hormone that transports glucose — or blood sugar — from… read more

Will 2D tin be the next super material for chip interconnects?

New single-layer material could go beyond graphene, conducting electricity with 100 percent efficiency at room temperature
November 25, 2013

Adding fluorine atoms (yellow) to a single layer of tin atoms (grey) should allow a predicted new material, stanene, to conduct electricity perfectly along its edges (blue and red arrows) at temperatures up to 100 degrees Celsius (212 Fahrenheit). (Yong Xu/Tsinghua University; Greg Stewart/SLAC)

Move over, graphene. “Stanene” —  a single layer of tin atoms — could be the world’s first material to conduct electricity with 100 percent efficiency at the temperatures that computer chips operate, according to a team of theoretical physicists led by researchers from the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory and Stanford University.

Stanene — the Latin name for tin (stannum) combined with the… read more

The FDA has approved marketing of four diagnostic devices from Illumina (a manufacturer of DNA sequencing machines) for “next generation sequencing” (NGS) — meaning the devices can now quickly and cheaply read and interpret large segments of the genome (the set of genetic information in your body) in a single test.

Two of the devices allow laboratories to sequence a patient’s genome for any purpose, according… read more

More-realistic 3D imaging technique speeds up production of movie images, modeling human organs

November 22, 2013

Isotropy vs. anisotropy

UT Dallas computer scientists have developed a technique to make 3D images faster and with more accuracy.

The method uses anisotropic (irregular) triangles — triangles with sides that vary in length depending on their direction — to create 3D “mesh” computer graphics that more accurately approximate the shapes of the original objects, and in a shorter amount of time than current techniques.

These types of images… read more
