Solar cells, light emitting diodes, displays and other electronic devices could get a bump in performance because of a discovery at the Department of Energy's Oak Ridge National Laboratory that establishes new boundaries for controlling band gaps.
Faster, smaller and more energy-efficient - that is what computers of the future should be like. A new phenomenon stands to make a major contribution in this direction: It needs 100,000 times less current than existing technologies, and the number of atoms needed for a data bit could diminish significantly.
As an initial step towards the development of the WHO/NANOH Guidelines, WHO prepared a draft background document proposing content and focus of the Guidelines. This background document will be used by the Guideline Development Group to identify key questions to be addressed by the Guidelines.
Wissenschaftler haben mit Experimenten erstmals das dynamische Verhalten korrelierter einzelner Atome in Festkoerpern simuliert. Es gelang ihnen, Atome in sogenannten optischen Gittern aufzureihen und deren dynamisches Verhalten zu beobachten, das durch das komplexe Zusammenspiel mit anderen Atomen bestimmt ist.
There's nothing ordinary about the materials being designed in the Stupp Laboratory at Northwestern University. Many of the futuristic fibers, films, gels, coatings and putty-like substances have led to important advances in areas of research such as regenerative medicine and energy technologies.
A new document from DECHEMA and VCI offers a summary of papers and work which have already been completed together with the results obtained, as well as a summary of the on-going activities and expected results. Here, the main focus of our considerations is on Germany, with a wider outlook on papers and results at European level.
Just one month into his appointment at the University of South Australia and Professor of Chemistry and Materials Science at the Mawson Institute, Dr Nico Voelcker, has won a prestigious Humboldt Research Fellowship to carry out a long-term research project in nanomaterials.
The smallest transistor ever built - in fact, the smallest transistor that can be built - has been created using a single phosphorous atom by an international team of researchers at the University of New South Wales, Purdue University and the University of Melbourne.
Just as NASA engineers test new rocket designs in computer studies before committing themselves to full prototypes, so physicists will often model matter under various circumstances to see whether something new appears. This is especially true of atomtronics, a relatively new science devoted to creating artificial tailored materials consisting of neutral atoms held in an array with laser beams, or atoms moving along a desired track under electric or magnetic influence. A new study shows how a simple "joystick" consisting of an adjustable magnetic field can create several new phases of atomtronic matter, several of them never seen before.
Researchers have created a living 3-D model of a brain tumor and its surrounding blood vessels. In experiments, the scientists report that iron-oxide nanoparticles carrying the agent tumstatin were taken by blood vessels, meaning they should block blood vessel growth. The living-tissue model could be used to test the effectiveness of nanoparticles in fighting other diseases.
