Nanomaterials are causing a revolution in fields as far apart as medicine, energy systems and consumer products. Despite their enormous potential, the production, use and disposal of these materials can entail risks for humans and the environment. The National Research Programme "Opportunities and risks of nanomaterials" (NRP 64) aims to identify both the risks and the opportunities of nanomaterials for human health, the environment and natural resources.
Pioneering researchers in Europe have done what no one has been able to do: surpass the limit on the sensitivity of a quantum measurement. The result could play a key role in interferometry and quantum limits of measurement.
Auf der am heutigen 4. April beginnenden Hannover Messe ist auch die Fachhochschule Brandenburg mit einem Exponat vertreten. Der Messeauftritt beschaeftigt sich primaer mit der Mitwirkung am internationalen Forschungsprojekt PARAFLUO, das im 7. Forschungsrahmenprogramm der EU gefoerdert wird.
Researchers at the Department of Informatics, University of Oslo, are developing sensors for the future. Their size decreases. They are more robust than today's sensors, communicate wirelessly, and even reduce energy consumption to a minimum. But more important: The researchers are connecting all sensors to the Future Internet.
A multidisciplinary team of researchers at UCLA has developed a "roadmap" of the complex signaling processes involved in cancer that could lead to new methods for diagnosing and overcoming such drug resistance.
A joint cooperation between three research groups at nanoGUNE (Donostia - San Sebastian, Spain) reports an innovative method to focus infrared light with tapered transmission lines to nanometer-size dimensions. This device could trigger the development of novel chemical and biological sensing tools, including ultra-small infrared spectrometers and lab-on-a-chip integrated biosensors.
GLOBALFOUNDRIES, one of the world's leading semiconductor foundries, has signed a strategic long-term partnership on sub-22nm CMOS scaling and GaN-on-Si technology with the nanoelectronics R+D center imec.
Scientists at the Institute of Bioengineering and Nanotechnology (IBN) and IBM Research - Almaden have developed the first biodegradable polymer nanoparticles to combat drug-resistant superbugs, such as Methicillin-Resistant Staphylococcus aureus (MRSA).
The discovery by two Penn State University researchers is a new type of symmetry in the structure of materials, which the researchers say greatly expands the possibilities for discovering or designing materials with desired properties. The research is expected to have broad relevance in many development efforts involving physical, chemical, biological, or engineering disciplines including, for example, the search for advanced ferroelectric ferromagnet materials for next-generation ultrasound devices and computers.
With the first observation of thermoelectric effects at graphene contacts, University of Illinois researchers found that graphene transistors have a nanoscale cooling effect that reduces their temperature.
Researchers at the Hebrew University of Jerusalem have achieved a breakthrough in the field of nanoscience by successfully altering nanocrystal properties with impurity atoms - a process called doping - thereby opening the way for the manufacture of improved semiconductor nanocrystals.
Physiker haben in einem neuartigen Ansatz gezeigt, wie die Ausbreitungsrichtung von Licht bzw. Lichtenergie auf der Ebene einzelner Molekuele manipuliert werden kann. Dazu platzierten die Biophysiker eine Kaskade von vier verschiedenen Fluoreszenz-Farbstoffmolekuelen auf einer DNA-Plattform im Nanometer-Massstab. Mithilfe eines sogenannten "Springer"-Farbstoffs gelang es ihnen, die Richtung des Lichtweges bzw. des Energietransfers zu kontrollieren.
