When gold turns invisible
Jun 01, 2017 (SPX)
Some materials luminesce, changing their color and intensity when under mechanical forces such as grinding or rubbing. These luminescent "mechanochromic" materi...
Bamboo inspires optimal design for lightness and toughness
Jun 01, 2017 (SPX)
Light and tough, bamboo is widely used as a natural, functional material in Japan and other Asian countries. Bamboo is light because of its hollow structure, wh...
Northrop Grumman receives AESA radar contract
Jun 01, 2017 (UPI)
The $243.9 million contract is for Active Electronically Scanned Array, or AESA, radars. Active Electronic Scanned Array radar is a phased array antenna detecti...
Computer scientists simplify deep learning
Jun 01, 2017 (UPI)
The simplification technique is similar to methods commonly used to minimize the amount of math required for data analysis. "This applies to any deep-learning a...
Breaking glass in infinite dimensions
May 31, 2017 (SPX)
The highly-ordered nature of crystals makes them fairly simple to understand mathematically, and physicists have developed theories that capture all sorts of cr...
New scaling law predicts how wheels drive over sand
May 31, 2017 (SPX)
Scientists can then apply scaling laws - mathematical relationships of proportionality - to extrapolate how a full-size jet would perform, based on the behavior...
New method allows real-time monitoring of irradiated materials
May 31, 2017 (SPX)
The new findings appear in the journal Applied Physics Letters, in a paper by graduate student Cody Dennett and assistant professor of nuclear science and engin...
Space junk could destroy satellites, hurt economies
May 31, 2017 (AFP)
There are an estimated 170 million pieces of so-called "space junk" -- left behind after missions that can be as big as spent rocket stages or as small as paint...
Argonne scientists make vanadium into a useful catalyst for hydrogenation
May 31, 2017 (SPX)
In a new study, Argonne chemist Max Delferro boosted and analyzed the unprecedented catalytic activity of an element called vanadium for hydrogenation - a react...
Model for 2-D materials based RRAM found
May 31, 2017 (SPX)
The research group led by Dr. Mario Lanza, a Young 1000 Talent Professor born in Barcelona (Spain) and based in Soochow University (China), is leading a global ...
Solving the riddle of the snow globe
May 31, 2017 (SPX)
A new Tel Aviv University study finds the sedimentation of asymmetric objects in liquid is very different from that of symmetrical objects like spheres. The res...
High pressure key to lighter, stronger metal alloys, Stanford scientists find
May 31, 2017 (SPX)
Humans have been blending metals together to create alloys with unique properties for thousands of years. But traditional alloys typically consist of one or two...
Neutron lifetime measurements take new shape for in situ detection
May 31, 2017 (SPX)
Neutrons, though, are inherently unstable (where lifetime, t, is approximately 881 seconds) and don't last long outside an atomic nucleus. Because the neutron d...
Strathclyde-led research develops world's highest gain high-power laser amplifier
May 30, 2017 (SPX)
They used 150 J pulses from the powerful Vulcan laser system at the Science and Technology Facilities Council's Central Laser Facility (CLF). Over the course of...
A new tool for discovering nanoporous materials
May 30, 2017 (SPX)
So far, chemists rely on visual inspection to see whether two materials have similar pores. EPFL scientists, in the framework of NCCR-MARVEL, have now developed...
Two simple building blocks produce complex 3-D material
May 30, 2017 (SPX)
Directed by design rules developed by the scientists, uranium atoms and organic linkers self-assemble into a beautiful crystal - a large, airy 3-D net of very r...
Atomic structure of irradiated materials is more akin to liquid than glass
May 30, 2017 (SPX)
But the similarities between the materials may not be as useful as previously thought, according to new results reported this week in The Journal of Chemical Ph...
Using light to rearrange macroscopic structures
May 30, 2017 (SPX)
For this purpose, scientists rely instead on "self-assembling" molecules, compounds that can interact with other copies of themselves to spontaneously congregat...
Achieving magnetic order in two-dimensional materials
May 30, 2017 (SPX)
Magnetic order is a common phenomenon in three-dimensional materials, such as ferromagnetic order in iron bar magnets, where the magnetic moments on all iron at...
Camera on NASA's Lunar Orbiter survived 2014 meteoroid hit
May 29, 2017 (SPX)
LROC is a system of three cameras mounted on the LRO spacecraft. Two Narrow Angle Cameras (NACs) capture high resolution black and white images. The third Wide ...
