Researchers have developed a novel membrane with highly aligned nanoscale pores that open and close in response to temperature; this highly porous, valve-like material has many potential filtration applications, including water purification and molecular separation.
The fullerene-free OPV module was created by thermally evaporating small molecules in different active layers. The process has been shown to improve the device stability, while at the same time opening up possibilities for further device engineering.
Researchers have succeeded in observing the 'forbidden' infrared spectrum of a charged molecule for the first time. These extremely weak spectra offer perspectives for extremely precise measurements of molecular properties and may also contribute to the development of molecular clocks and quantum technology.
University leaders and nanotechnology researchers joined representatives from industry and government agencies at Northeastern's George J. Kostas Research Institute for Homeland Security to unveil NanoOPS, a nanoscale printing system with the potential to transform nanomanufacturing and spur innovation in a range of areas including electronics, medicine, and energy storage.
Faster, smaller, greener computers, capable of processing information up to 1,000 times faster than currently available models, could be made possible by replacing silicon with materials that can switch back and forth between different electrical states.
An official of a materials technology and manufacturing startup based on a Purdue University innovation says his company is addressing the challenge of scaling graphene production for commercial applications.
Scientists are experimenting with a new method of gelation. They can add nanoparticles or biomolecules with useful pH, chemical, and temperature sensing properties into a liquid, but incorporating those liquids into existing technology proves difficult.
For decades, polymer scientists and synthetic chemists working to improve the power conversion efficiency of organic solar cells were hampered by the inherent drawbacks of commonly used metal electrodes, including their instability and susceptibility to oxidation. Now for the first time, researchers have developed a more efficient, easily processable and lightweight solar cell that can use virtually any metal for the electrode, effectively breaking the 'electrode barrier'.
Physicists experimentally observed how the anisotropic properties of particles deform the Fermi surface in a quantum gas. The work published in Science provides the basis for future studies on how the geometry of particle interactions may influence the properties of a quantum system.
