Microwires made of silicon have a wide range of possible uses, including the production of solar cells that can harvest much more sunlight for a given amount of material than a conventional solar cell made from a thin wafer of silicon crystal. Now researchers from MIT and Penn State have found a way of producing such wires in quantity in a highly controlled way that could be scaled up to an industrial-scale process, potentially leading to practical commercial applications.
Ben-Gurion University of the Negev researcher Dr. Taleb Mokari, a member of the Ilse Katz Institute for Nanoscale Science and Technology, has been awarded a prestigious Krill Prize for Excellence in Scientific Research. Dr. Mokari received the Prize for his work on developing novel nanostructures for renewable energy applications.
The Micro- and Nanotechnology Research Group of the Universitat Politecnica de Catalunya has produced silicon photovoltaic cells with a conversion efficiency of 20.5%, the highest level achieved in Spain using this material.
The human olfactory system possesses a special electric amplification mechanism that enables olfactory cells to respond even to extremely weak stimuli. Scientists at Heidelberg University have now established how this mechanism works.
The website WellHome has created a nice infographic that gives an overview of what graphene is and what areas - such as computing, manufacturing, or energy - could be profoundly impacted by this nanomaterial.
Das Landesanstalt fuer Umwelt, Messungen und Naturschutz Baden-Wuerttemberg hat eine neue Broschuere herausgegeben mit dem Titel "Nanomaterialien: Anwendungen im Umweltbereich". Diese Broschuere stellt Beispiele fuer den Einsatz von Nanomaterialien vor, die zu deutlichen Umweltentlastungen fuehren koennen.
On Feb. 17, Penn President Amy Gutmann will join University Trustees and the deans of the Schools of Arts and Sciences (SAS) and Engineering and Applied Science at the 3200 block of Walnut Street for a groundbreaking ceremony for the Krishna P. Singh Center for Nanotechnology.
An interdisciplinary team of UC Davis and UC Santa Cruz researchers is taking a novel approach to solar power, one that promises to lead to a technological breakthrough. By using nanoparticles of germanium, silicon and other materials, the researchers hope to produce solar cells far more efficient than the current state of the art.
Researchers at the Department of Energy's Oak Ridge National Laboratory have developed a biohybrid photoconversion system -- based on the interaction of photosynthetic plant proteins with synthetic polymers -- that can convert visible light into hydrogen fuel.
In a paradox typical of the quantum world, JILA scientists have eliminated collisions between atoms in an atomic clock by packing the atoms closer together. The surprising discovery can boost the performance of experimental atomic clocks made of thousands or tens of thousands of neutral atoms trapped by intersecting laser beams.
In typical plasmonic devices, electromagnetic waves crowd into tiny metal structures, concentrating energy into nanoscale dimensions. Due to coupling of electronics and photonics in these metal nanostructures, plasmonic devices could be harnessed for high-speed data transmission or ultrafast detector arrays. However, studying plasmonic fields in nanoscale devices presents a real roadblock for scientists, as examining these structures inherently alters their behavior.
A new way of splitting layered materials to give atom thin "nanosheets" has been discovered. This has led to a range of novel two-dimensional nanomaterials with chemical and electronic properties that have the potential to enable new electronic and energy storage technologies.
An international interdisciplinary consortium of more than 20 laboratories has achieved an extraordinary feat: producing an ultra powerful X-ray laser beam to visualize a single viral particle in a single flash lasting several femtoseconds.
