When atoms in a crystal are struck by laser light, their electrons, excited by the light, typically begin moving back and forth together in a regular pattern, resembling nanoscale soldiers marching in a lockstep formation. But according to a new theory developed by Johns Hopkins researchers, under the right conditions these atoms will rebel against uniformity.
The institution, jointly established by the Swiss Federal Institute of Aquatic Science and Technology (Eawag) and the Federal Institute of Technology Lausanne (EPFL), has a federal mandate to strengthen independent research, consulting and training in the ecotoxicology field.
First, the good news: young people in Europe are overwhelmingly interested in science and technology and positive about the benefits they bring to society, according to a new Eurobarometer survey on young people's attitudes to science. The bad news is that few are interested in pursuing a scientific career.
Researchers at the National Institute of Advanced Industrial Science and Technology (AIST) in Japan have developed polymer films that change color instantaneously and reversibly in response to changes in the tension applied.
United Arab Emirates (UAE) Higher Education and Scientific Research Minister HE Sheikh Nahyan bin Mubarak Al Nahyan, opened today the second International Conference on Bio-Nanotechnology conference at the Abu Dhabi National Exhibition Centre.
Chemists can learn from some shellfish. Mussels, for example, produce an adhesive that sticks strongly to metal and stone, even under water. Chemists have reproduced the protein responsible for this in a synthetic material that contains the same adhesive elements.
Researchers from the Universidad Politecnica de Madrid have developed a prototype metropolitan quantum key distribution network that will be ready for deployment by Telefonica on any Spanish urban telecommunications network by 2010.
A new class of exceptionally effective chemical catalysts that promote the powerful olefin metathesis reaction has been discovered by a team of Boston College and MIT scientists, opening up a vast new scientific platform to researchers in medicine, biology and materials.
The SPMage09 competition has the aim to recognize the important contributions to Nanoscience and Nanotechnology that have been made by the many nano initiatives underway around the world. An international jury of prominent researchers in the field of SPM will judge the images submitted to the Image Prize competition.
