'Liquid Armor' Toughens Spacesuits

The technology, shear thickening fluid, permeates fabrics and layers of material and actually gets stronger when it is struck with increasing force, making the material highly puncture and ballistic-resistant. The nanocomposite material, sometimes called "liquid armor," adds little weight to the fabric and does not reduce its flexibility - two critical features for a space suit. NASA recently provided a grant for its study and prototypes will be sent for testing on the International Space Station in November.

On the Road to Fire-Free, Lithium-Ion Batteries Made with Asphalt

Lithium-ion batteries can be found in everything from cell phones to hoverboards, but these power sources have recently made headlines for the fires they have inadvertently caused. To address these safety hazards, scientists report in ACS Nano that they are paving the way to better batteries with a naturally occurring form of asphalt.

Solar-Powered Devices Made of Wood Could Help Mitigate Water Scarcity Crisis

Energy from the sun and a block of wood smaller than an adult’s hand are the only components needed to heat water to its steaming point in these purifying devices.

Spin-Current Generation Gets Mid-IR Boost with Plasmonic Metamaterial

Researchers have begun to use metamaterials, engineered composites that have unique properties not found in nature, to enhance the absorption rates of plasmonic absorbers, and a team in Japan used a trilayered metamaterial to develop a wavelength-selective plasmonic metamaterial absorber on top of a spintronic device to enhance the generation of spin currents from the heat produced in the mid-infrared regime. The research is reported this week in APL Photonics.

Forget About It

Forget_Story_Figure_1_900p.jpg

Inspired by human forgetfulness – how our brains discard unnecessary data to make room for new information — scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory, in collaboration with Brookhaven National Laboratory and three universities, conducted a recent study that combined supercomputer simulation and X-ray characterization of a material that gradually “forgets.” This could one day be used for advanced bio-inspired computing.

Scientists Use Machine Learning to Translate 'Hidden' Information that Reveals Chemistry in Action

UPTON, NY—Chemistry is a complex dance of atoms. Subtle shifts in position and shuffles of electrons break and remake chemical bonds as participants change partners. Catalysts are like molecular matchmakers that make it easier for sometimes-reluctant partners to interact. Now scientists have a way to capture the details of chemistry choreography as it happens.

Prototype Shows How Tiny Photodetectors Can Double Their Efficiency

UC Riverside physicists have developed a photodetector – a device that converts light into electrons – by combining two distinct inorganic materials and producing quantum mechanical processes that could revolutionize the way solar energy is collected. The researchers stacked two atomic layers of tungsten diselenide on a single atomic layer of molybdenum diselenide. Such stacking results in properties vastly different from those of the parent layers, allowing for customized electronic engineering at the tiniest possible scale.

Paper-Based Supercapacitor Uses Metal Nanoparticles to Boost Energy Density

Using a simple layer-by-layer coating technique, researchers from the U.S. and Korea have developed a paper-based flexible supercapacitor that could be used to help power wearable devices. The device uses metallic nanoparticles to coat cellulose fibers in the paper, creating supercapacitor electrodes with high energy and power densities – and the best performance so far in a textile-based supercapacitor.
