Trapping light with an optical version of a whispering gallery, researchers have developed a nanoscale coating for solar cells that enables them to absorb about 20 percent more sunlight than uncoated devices.
The surface of materials can have an enormous influence on their function. If the external properties are changed, this also expands the range of possible applications. This is why materials scientists are researching how they can tailor the surfaces of different materials using laser technology.
Scientists describe with atomic detail how molecules are transported through biological membranes. Computer simulations and spectroscopic experiments provided insights into the work of so-called ABC transporters.
Researchers use a technique called DNA origami to mimic a multitude of vital movements seen in nature, such as the sliding motion exerted by protein motors during cell division. Their invention features a preliminary attempt to construct nanoscale analogues of the mysterious natural machines in living cells.
Researchers demonstrate that the oxidative unzipping of MWCNTs is intercalation-driven, not oxidative chemical-bond cleavage as was formerly proposed. The unzipping mechanism involves three consecutive steps: intercalation-unzipping, oxidation, and exfoliation.
A time-resolved x-ray experiment elucidates that tiny atomic vibrations shift negative charges over a 1000 times larger distance between atoms and switch the macroscopic polarization on a time scale of a millionth of a millionth of a second.
