It's hard to get an X-ray image of low-density material like tissue between bones because X-rays just pass right through like sunlight through a window. Sandia studies myriads of low-density materials, from...
Briefs: Nanotechnology
To keep up with Moore's Law — an observation made in the 1960s that the number of transistors on an integrated circuit doubles about every two years — researchers are...
Briefs: Photonics/Optics
Light is the most energy-efficient way to move information; however, light shows one big limitation: it is difficult to store. Data centers, for example, rely primarily on magnetic hard drives in...

Single-Crystal SiGe/Sapphire Epitaxy
NASA's Langley Research Center has developed a new low-temperature method of SiGe/sapphire growth that produces the same single-crystal films with much less thermal loading effort to the substrate. This eliminates the time-consuming and costly high heating, long thermal soak times, and interfacial Si layer....

Ultrasensitive Chip-Based Sensors
An optical whispering gallery mode resonator was developed that can spin light around the circumference of a tiny sphere millions of times, creating an ultrasensitive, microchip-based sensor for multiple applications.
Briefs: Sensors/Data Acquisition
Pressure sensors play an important role in engine maintenance and monitoring systems by diagnosing problems before they happen. To capture the most accurate data, however, these sensors must be...

Gated Chopper Integrator (GCI)
Microvolt-level signals require gains of at least a thousand. Offsets and noise in the amplifier chain will be amplified by the same amount, which can saturate the amplifier or swamp the signal so it is not resolvable. Other methods use chopping and/or autozero techniques to lower the offset and noise. The key...

The detection and localization of gas releases, such as methane from leaking natural gas pipelines or nitrogen oxides from failing electrical equipment, require high sensitivity to the target gas and insensitivity to...
Briefs: Transportation
It is relatively easy to measure small movements of large objects, but is much more difficult when the moving parts are on the scale of nanometers, or billionths of a meter. The ability to accurately...
