In 3D printing — also known as additive manufacturing — an object is built layer-by-layer, allowing for the creation of structures that would be impossible to manufacture by...

Most electronic devices have glass or plastic covers that protect against dust, moisture, and other environmental contaminants, but light reflection from these surfaces can make...

Sandia National Laboratories — headquartered in Albuquerque, MN, with a principal lab in Livermore, CA — is operated and managed by National Technology and Engineering Solutions of Sandia, LLC (a wholly owned...

A new painless and minimally invasive microneedle technology can extract large volumes of pure interstitial fluid for further study. Developed at Sandia Labs and the University of New Mexico, the microneedles are a few...

High-tech refrigerators have been used to reach temperatures as close to absolute zero as possible — 0 kelvin or -273.15 °C. Physicists aim to cool equipment to as close to absolute zero as...

A wireless triboelectric nanogenerator (W-TENG) generates electricity from motion and vibrations. It consists of a biodegradeable polymer and graphene. When the two materials are brought...

Carbon aerogels (CAs) are nano-porous carbons comprising a particularly significant class of carbon nano-materials for a variety of sustainable energy applications. Carbon aerogels are...

NASA's Marshall Space Flight Center has developed a solid-state ultracapacitor with a unique combination of high capacitance and battery-like discharge characteristics. The high capacitance in...

A silicon solar cell harvests the energy of the sun as light travels down through light-absorbent silicon. To reduce weight and cost, solar cells are thin, and while silicon absorbs...
