Super Tiny Giraffe is UC Riverside graduate student Shaahin Amini's entry for the "Science as Art" competition, sponsored by the MRS (Materials Research Society). The photos are of a mix of nickel, aluminum and carbon viewed through a high-powered microscope.
A University of Washington mathematician is part of an international team working to understand invisibility and extend its possible applications. The group has now devised an amplifier that can boost light, sound or other waves while hiding them inside an invisible container.
Duke University chemists created a new set of flexible, electrically conductive nanowires from thin strands of copper atoms mixed with nickel. The copper-nickel nanowires, in the form of a film, conduct electricity even under conditions that break down the transfer of electrons in plain silver and copper nanowires, a new study shows.
Scientists at the Joint Quantum Institute have stored not one but two letters of the alphabet in a tiny cell filled with rubidium atoms which are tailored to absorb and later re-emit messages on demand. This is the first time two images have simultaneously been reliably stored in a non-solid medium and then played back.
The Organic Electronics research group at Linkoping University previously developed ion transistors for transport of both positive and negative ions, as well as biomolecules. They have now succeeded in combining both transistor types into complementary circuits, in a similar way to traditional silicon-based electronics.
Researchers investigated if there was a common underlying mechanism contributing to the development of autoimmune diseases operating at the level of human cells following their exposure to nanoparticles of different nature and possessing diverse physical and chemical properties.
The 8th NanoBio-Europe conference will take place on 18 - 20 June 2012 in Varese (Lombardy, Northern Italy), showcasing the latest international developments in nanobiotechnology, and providing a platform to facilitate interdisciplinary communications, new collaborations for delegates from academic, industrial and clinical backgrounds.
The European Chemicals Agency (ECHA) has published three new appendices, updating Chapters R.8, R.10 and R.14 of the Guidance on Information Requirements and Chemical Safety Assessment. These appendices focus on Chemical Safety Assessment and provide further recommendations for registering nanomaterials.
Chairman of the Standardization Committee of Iran Nanotechnology Initiative Council (INIC) Dr. Ali Beitollahi announced the formation of a network for safety and health affairs in the field of nanotechnology.
In der neu vorliegenden, von Bundesanstalt fuer Arbeitsschutz und Arbeitsmedizin (BAuA) und Verband der Chemischen Industrie (VCI) aktualisierten und konkretisierten "Empfehlung fuer die Gefaehrdungsbeurteilung bei Taetigkeiten mit Nanomaterialien am Arbeitsplatz" werden u. a. neue Erkenntnisse zu Messverfahren und Messstrategien beruecksichtigt.
London Centre for Nanotechnology researchers have developed a scalable solution-based method that produces greatly improved yields of single-layer graphene, which can then be deposited onto substrates.
Using expertise in the design and fabrication of micro- and nanoscale devices, a new strategy for engineering low-frequency noise oscillators capitalizes on the intrinsic nonlinear phenomena of micro- and nanomechanical resonators.
