Helium 'balloons' offer new path to control complex materials
Researchers at the Department of Energy's Oak Ridge National Laboratory have developed a new method to manipulate a wide range of materials and their behavior using only a handful of helium ions.
Ocean cycling of nitrous oxide is more intense than thought, emissions are increasing
Nitrous oxide (N2O) is a potent greenhouse gas that can contribute to climate change and damage the ozone layer. But its cycling in and out of ocean waters has remained poorly understood, making it difficu ...
Researchers create first neural-network chip built just with memristors
Chemists' synthesis of silicon oxides opens 'new world in a grain of sand'
In an effort that reaches back to the 19th-century laboratories of Europe, a discovery by University of Georgia chemistry researchers establishes new research possibilities for silicon chemistry and the semiconductor ...
Graphene champions the next generation 3D display technology
Moving holograms like those used in 3D science fiction movies such as Avatar and Elysium have to date only been seen in their full glory by viewers wearing special glasses.
Chemists make new silicon-based nanomaterials
Chemists from Brown University have found a way to make new 2-D, graphene-like semiconducting nanomaterials using an old standby of the semiconductor world: silicon.
NASA's Curiosity rover finds fresh signs of ingredients for life on Mars
Mars's life-friendly past just got friendlier. Using samples previously collected by the NASA rover Curiosity, scientists have discovered evidence of nitrates in Martian rock: nitrogen compounds that on Earth ...
Scientists develop cool process to make better graphene
A new technique invented at Caltech to produce graphene—a material made up of an atom-thick layer of carbon—at room temperature could help pave the way for commercially feasible graphene-based solar cells ...
One step closer to artificial photosynthesis and 'solar fuels'
Caltech scientists, inspired by a chemical process found in leaves, have developed an electrically conductive film that could help pave the way for devices capable of harnessing sunlight to split water into ...
Simulating superconducting materials with ultracold atoms (w/ Video)
Using ultracold atoms as a stand-in for electrons, a Rice University-based team of physicists has simulated superconducting materials and made headway on a problem that's vexed physicists for nearly three ...
