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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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 ...
One-dimensional crystals for low-temperature thermoelectric cooling
May 28, 2017 (SPX)
Coolers based on thermoelectric technology can be scaled down in size without changing their thermal-to-electrical energy conversion efficiency and this is a ma...
Collecting real-time data for material microstructural evolution during radiation exposure
May 26, 2017 (SPX)
Today, most irradiated materials testing involves designing a material, exposing it to radiation, and destructively testing the material to determine how its pe...
New theory predicts wetted area of droplets colliding with flat surface
May 26, 2017 (SPX)
In the past, researchers from all over the world have attempted to make quantitative predictions about the extent of wetted areas through experimentation, theor...
Physicists discover mechanism behind granular capillary effect
May 25, 2017 (SPX)
But what happens if the tube is dipped into a container filled not with water but with sand? The answer is - nothing. However, if the tube is shaken up and down...
Swirling swarms of bacteria offer insights on turbulence
May 24, 2017 (SPX)
A team of physicists led by Rockefeller University fellow Tyler Shendruk recently detected a telling mathematical signature inscribed in that disintegration fro...
Self-ventilating workout suit keeps athletes cool and dry
May 24, 2017 (SPX)
The researchers have also fashioned a running shoe with an inner layer of similar cell-lined flaps to air out and wick away moisture. Details of both designs ar...
New Zealand company partners with U.S. Army for engineered skin
May 24, 2017 (UPI)
The Cooperative Research and Development Agreement, or CRADA, with the Army's Medical Research and Materiel Command is for Upside's engineered skin product deve...
Not all cool pavements are created equal
May 24, 2017 (SPX)
Scientists in Berkeley Lab's Heat Island Group, in collaboration with the UC Pavement Research Center (UCPRC), the University of Southern California (USC), and ...
A recipe for concrete that can withstand road salt deterioration
May 24, 2017 (SPX)
More than 900,000 tons of deicing salt is used each winter in Pennsylvania alone. While winters in the Northeast put pressure on departments of transportation t...
