Engineered nanoparticles can be used to treat cancer

A Sandia National Laboratories team has designed and synthesised nanoparticles that glow red and are stable, useful properties for tracking cancer growth and spread. This work is the first time the intrinsic luminescence of metal-organic framework materials, or MOFs, for long-term bioimaging has been reported, materials chemist Dorina Sava Gallis said. Fluorescently-tagging tumours, or other specific kinds of cells, is a new, powerful method to i...

Microneedle patch collects samples of interstitial fluid

Interstitial fluid, which resembles blood plasma and that is reachable near the surface of the skin, contains many biomarkers, including sodium, potassium, and proteins, associated with normal body function, as well as those related to certain diseases. Researchers from Sandia National Laboratories and University of New Mexico have been working on a new microneedle patch that can draw large quantities of interstitial fluid for laboratory testing.

Brain stimulation during training improves performance

According to Sandia National Laboratories cognitive scientist Mike Trumbo, learning a language or an instrument or going dancing is the best way to keep your brain keen despite the ravages of time. Not only do you enhance your cognition but you also learn a skill and have fun. Several commercial enterprises have claimed you can get cognitive benefits from brain training games intended to enhance working memory.

Sandia develops 3D metasurfaces with optical possibilities

Sandia National Laboratories researchers are helping lead the way to the use of III-V semiconductors as the building blocks of metamaterials. (III-V refers to elements in those columns in the periodic table.) Sandia researchers have published technical papers, including three in the past year, on work featuring materials like gallium-arsenide and aluminum-arsenide, which are more efficient than metals for optical metamaterial applications, with w...

Diodes made from semiconductor materials perform better than silicon

Sandia National Laboratories researchers have shown it's possible to make transistors and diodes from advanced semiconductor materials that could perform much better than silicon, the workhorse of the modern electronics world. The breakthrough work takes a step toward more compact and efficient power electronics, which in turn could improve everything from consumer electronics to electrical grids.

Focusing on the brain to reboot computing

Computer scientists are scrambling for new ideas: new devices built using novel physics, new ways of organising units within computers and even algorithms that use new or existing systems more efficiently. To help coordinate new ideas, Sandia National Laboratories has assisted organising the Institute of Electrical and Electronics Engineers (IEEE) International Conference on Rebooting Computing held Oct. 17-19.

Cooling method for supercomputers to save millions of gallons of water

  In different parts of the country, people discuss gray-water recycling and rainwater capture to minimise the millions of gallons of groundwater required to cool large data centres. But the simple answer in many climates, said Sandia National Laboratories researcher David J. Martinez, is to use liquid refrigerant.

Encrypting and storing sensitive data securely in DNA

George Bachand, a Sandia National Laboratories bioengineer at the Center for Integrated Nanotechnologies, is exploring a better, more permanent method for encrypting and storing sensitive data: DNA. Compared to digital and analog information storage, DNA is more compact and durable and never becomes obsolete. Readable DNA was extracted from the 600,000-year-old remains of a horse found in the Yukon.

UXI is the world's fastest multiframe digital X-ray camera

Sandia National Laboratories researchers have put together the fastest multiframe digital X-ray camera in the world, called the ultra-fast X-ray imager (UXI). The camera takes images with an exposure time of only 1.5 nanoseconds—25 times faster than the best digital cameras. "People are captivated by movies," said Sandia physicist John Porter. "We just want to make sure there are no surprises between the frames."

Palm tree style wind turbine design can withstand hurricanes

Sandia National Laboratories’ research on the extreme-scale Segmented Ultralight Morphing Rotor (SUMR) is funded by the Department of Energy’s (DOE) Advanced Research Projects Agency-Energy programme. The project's challenge is to design a low-cost offshore 50MW, 200m exascale turbine requiring a rotor blade more than 650ft long, two and a half times longer than any existing wind blade.
