The ties that bind: Recreating Darwinian ligand evolution in vitro
Highly efficient nanoparticles could bring down the cost of fuel cells
(Phys.org) —Fuel cells are a promising, non-polluting way to power cars, but their platinum catalysts are so expensive that there's no way current technology could be economically scaled up for widespread ...
Ultrafast X-ray laser sheds new light on fundamental ultrafast dynamics
Ultrafast X-ray laser research led by Kansas State University has provided scientists with a snapshot of a fundamental molecular phenomenon. The finding sheds new light on microscopic electron motion in molecules.
Discovery provides insights on how plants respond to elevated CO2 levels
Biologists at UC San Diego have solved a long-standing mystery concerning the way plants reduce the numbers of their breathing pores in response to rising carbon dioxide levels in the atmosphere.
Water behavior breakthrough opens a crucial door in chemistry
(Phys.org) —A multi-institutional team has resolved a long-unanswered question about how two of the world's most common substances interact.
Familiar yet strange: Water's 'split personality' revealed by computer model
Seemingly ordinary, water has quite puzzling behavior. Why, for example, does ice float when most liquids crystallize into dense solids that sink?
Nanotube forests drink water from arid air
(Phys.org) —If you don't want to die of thirst in the desert, be like the beetle. Or have a nanotube cup handy. New research by scientists at Rice University demonstrated that forests of carbon nanotubes ...
DNA-linked nanoparticles form switchable 'thin films' on a liquid surface
Scientists seeking ways to engineer the assembly of tiny particles measuring just billionths of a meter have achieved a new first—the formation of a single layer of nanoparticles on a liquid surface where ...
Researchers discover how a cluster of water molecules adapts to the presence of an extra proton
(Phys.org) —H2O is the molecule everybody knows, and nobody can live without. But for all its familiarity and import for life, aspects of water's behavior have been hard to pin down, including how it con ...
Unexpected water explains surface chemistry of nanocrystals
Danylo Zherebetskyy and his colleagues at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) found unexpected traces of water in semiconducting nanocrystals.
Relaxation helps pack DNA into a virus
Researchers at the University of California, San Diego have found that DNA packs more easily into the tight confines of a virus when given a chance to relax, they report in a pair of papers to be published ...
Chemists challenge conventional understanding of how photocatalysis works
Photocatalysis—catalysis assisted by light—is a promising route to convert solar energy into chemical fuels. Particularly appealing is the possibility to use photocatalysis to split water molecules into ...
Using light to identify chiral molecules for pharmaceuticals
(Phys.org) —A combination of nanotechnology and a unique twisting property of light could lead to new methods for ensuring the purity and safety of pharmaceuticals.
Atoms and molecules on the same wavelength
(Phys.org) —It may be surprising, but in physics the terrain of atoms and the territory of organic molecules are worlds apart. Therefore, in order to have a molecule communicate optically with atoms, the ...
