Using nanocrystals of cellulose, the main component of pulp and paper, chemistry researchers at the University of British Columbia have created glass films that have applications for energy conservation in building design because of their ability to reflect specific wavelengths of light, such as ultra violet, visible or infrared.
The research on materials' surface layers with spectroscopic methods, extremely important for nanotechnology, material engineering, microelectronics and many other areas, requires knowledge of certain physical parameters that are available in the databases distributed by the US National Institute of Standards and Technology (NIST). Used by the researchers worldwide, several of these databases are being developed by Prof. Aleksander Jablonski from the Institute of Physical Chemistry of the Polish Academy of Sciences.
Imec, together with its partners within the European FP6 Program NeuroProbes, has created a new neural probe enabling electrical and chemical recording and stimulation of single neurons in the brain. Applications of the new technology are vast, ranging from tools for fundamental research on the functioning of the brain, to instruments for more precise diagnosis of brain seizures before brain-surgery.
The nanoelectronics research centre imec and Peira, a Belgium-based manufacturer of pharmaceutical and chemical research instruments, jointly developed an innovative slice-tilting instrument for in-vitro research on brain tissue. The new tool enables long-term studying of brain cultures through electronic stimulation and read-out, essential in getting insight into the functioning of the brain.
Seven companies reported using six nanomaterials in response to a voluntary information call in 2008 by Australia's National Industrial Notification and Assessment Scheme (NICNAS), in contrast to 22 companies reporting on 21 types of nanomaterial two years earlier.
A new report, 'Nanotechnology Research Directions for Societal Needs in 2020' outlines the foundational knowledge and infrastructure development in the last decade, the current $15 billion in R+D programs underpinning about $250 billion of products incorporating nanoscale components in the world in 2009, and the likely evolution towards a general purpose technology by 2020.
Because environmental and health information on carbon nanotubes is incomplete and sometimes conflicting, an 'anticipatory governance' approach to the technology is needed, according to Mark Philbrick, post-doctoral researcher at the Center of Integrated Nanomechanical Systems at the University of California, Berkeley.
DNA is an outstanding nanoscale building material, as researchers led by Ned Seeman discovered thirty years ago. Seeman and his colleagues at the New York University have now used cross-shaped DNA tiles to produce an amazingly large grid structure that resembles woven fabric.
Researchers have demonstrated a new imaging tool for rapidly screening structures called single-wall carbon nanotubes, possibly hastening their use in creating a new class of computers and electronics that are faster and consume less power than today's.
Researchers were able to produce nanopillars that absorb light as well or even better than commercial thin-film solar cells, using far less semiconductor material and without the need for anti-reflective coating.
In einem Positionspapier zum verantwortungsvollen Umgang mit Nanomaterialien (greift die DGUV die Empfehlungen der Nanokommission auf und legt ihre Handlungsfelder fuer zielgerichtete Praeventionsaktivitaeten fest. Dabei empfiehlt es sich, den Arbeitsschutzgedanken bereits bei der Etablierung von Nanotechnologien in den Unternehmen zu verankern.
