An urgent challenge currently faced by researchers and the public alike is the ability to identify the next generation of sustainable, cost-effective, and energy efficient materials for our everyday use. While searching for new materials for electrical energy storage, a team of Drexel University materials scientists has discovered a new family of two-dimensional compounds proposed to have unique properties that may lead to groundbreaking advances in energy storage technology.
In microfluidic devices, small separated droplets flow in a stream of carrier liquid. Occasionally, selected droplets have to be merged to carry out a chemical reaction. This can be greatly facilitated with the use of electric field, through a process of electrocoalescence that has been used industrially in large scale applications. Researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences have found the laws governing the process and how to maximise the efficiency of merging.
This podcast is based on a review article in ACS' Journal of Agricultural and Food Chemistry, in which the scientists analyzed nearly 100 scientific articles on the effects of different types of nanoparticles on edible plants.
New medicines containing nanoparticles are proven to have clear curative value, but complications can sometimes arise. Researchers at the Norwegian Radium Hospital in Oslo have shown how nanoparticles can interfere with the transport of vital substances in cells.
A delicate balance of atomic forces can be exploited to make nanoparticle superclusters that are uniform in size - an attribute that's important for many nanotechnology applications but hard to accomplish, University of Michigan researchers say.
Researchers utilizing high-brightness x-rays at the U.S. Department of Energy Office of Science's Advanced Photon Source at Argonne National Laboratory have demonstrated that synthetic, nearly defect-free diamond crystals can reflect more than 99% of hard x-ray photons backward in Bragg diffraction, with a remarkably small variation in the magnitude of reflectivity across the sample.
Graphene, considered the most exciting new material under study in the world of nanotechnology, just got even more interesting, according to a new study by a group of researchers at the University of Colorado Boulder.
The Center of Innovation for Nanobiotechnology, a non-profit commercialization center dedicated to the development and growth of nanobiotechnology related industries, announced today that Griffith Kundahl has been named Executive Director of the organization.
The latest developments of microscopy in materials science and life sciences are at the forefront of the Microscopy Conference 2011 in Kiel, from August 28 to September 2. Over 550 experts will be exchanging information on structure research using electron microscopy and related methods, and sharing opinions on the latest research topics.
Researchers at the University of Wisconsin-Madison, describe a new energy-harvesting technology that promises to dramatically reduce our dependence on batteries and instead capture the energy of human motion to power portable electronics.
Wissenschaftlern vom Center for Nanointegration Duisburg-Essen (CeNIDE) ist es erstmals gelungen, effiziente Nanomaterialien fuer thermoelektrische Anwendungen aus der Gasphase zu synthetisieren. Das Ergebnis ist eine aeusserst homogene Silizium-Germanium-Legierung mit extrem niedriger Waermeleitfaehigkeit.
To highlight breakthroughs in femtosecond laser systems, the editors of the Optical Society's (OSA) open-access journal Optical Materials Express have published a special Focus Issue on Femtosecond Direct Laser Writing and Structuring of Materials.
