Experimental evidence and computer simulations suggest how to grow structures with the best trade offs between 3 desired characteristics: strength, flexibility and the ability to dissipate heat
When engineers design devices, they must often join together two materials that expand and contract at different rates as temperatures change. Such thermal differences can cause problems if, for instance, a semiconductor chip is plugged into a socket that can't expand and contract rapidly ...
Scientists able to study a photosynthetic complex -- arguably the most important bit of organic chemistry on the planet -- in its complete functioning state
When sunlight strikes a photosynthesizing organism, energy flashes between proteins just beneath its surface until it is trapped as separated electric charges. Improbable as it may seem these tiny hits of energy eventually power the growth and movement of all plants and animals. They are ...
Slowly cooled DNA transforms disordered nanoparticles into orderly crystal
Nature builds flawless diamonds, sapphires and other gems. Now a Northwestern University research team is the first to build near-perfect single crystals out of nanoparticles and DNA, using the same structure favored by nature. "Single crystals are the backbone of many things we rely on -- ...
A force that intricately links the rotation of the Earth with the direction of weather patterns in the atmosphere has been shown to play a crucial role in the creation of the hypnotic patterns created by the skirts of the Whirling Dervishes. This is according to an international group of ...
University of Illinois researchers have developed a way to heal gaps in wires too small for even the world’s tiniest soldering iron. Led by electrical and computer engineering professor Joseph Lyding and graduate student Jae Won Do, the Illinois team published its results in the journal Nano ...
Roots of superfluorescent bursts from quantum wells
Spontaneous bursts of light from a solid block illuminate the unusual way interacting quantum particles behave when they are driven far from equilibrium. The discovery by Rice University scientists of a way to trigger these flashes may lead to new telecommunications equipment and other ...
Collaborative atmospheric study indicates fossil fuel extraction and animal husbandry are major contributors
Emissions of methane from fossil fuel extraction and refining activities in the south-central United States are nearly five times higher than previous estimates, according to researchers at Harvard University and seven other institutions. Their study, published this week in PNAS, also ...
Better understanding of hardy bacteria enhances tool for biofuel creation
Scientists have charted a significant signaling network in a tiny organism that's big in the world of biofuels research. The findings about how a remarkably fast-growing organism conducts its metabolic business bolster scientists' ability to create biofuels using the hardy microbe ...
Copper nanowires offer an efficient, inexpensive approach to solar energy harvesting
Copper adorns the Statue of Liberty, makes sturdy, affordable wiring, and helps our bodies absorb iron. Now, researchers at Duke University would like to use copper to transform sunlight and water into a chemical fuel. Converting solar energy into storable fuel remains one of the greatest ...
Cabot Corporation announced that it has completed its acquisition of the equity stake owned by Grupo Kuo S.A.B. de C.V. (KUOB.MX) in its Mexican carbon black manufacturing joint venture, NHUMO, S.A.de C.V. NHUMO is the leading carbon black producer inMexico, and the acquisition of Kuo’s ...
