The nanostars gyrate when exposed to a rotating magnetic field and can scatter light to produce a pulsating or 'twinkling' effect. This twinkling allows them to stand out more clearly from noisy backgrounds like those found in biological tissue
To understand transformations of matter, scientists at DOE?s Pacific Northwest National Laboratory aided in developing methods to determine how fast clusters of molecules form and their corresponding stability.
A team of researchers from Yale University and a Spanish company have developed a system to detect the vapours emitted by human skin in real time. The scientists think that these substances, essentially made up of fatty acids, are what attract mosquitoes and enable dogs to identify their owners.
Development of high-performance batteries is an indispensable prerequisite for the economic efficiency of electric cars. For Germany to reach a top level in international electrochemistry research again, the Federal Ministry of Education and Research (BMBF) is now funding a consortium of selected universities and non-university research institutions in southern Germany.
The Chicago chapter of the Association for Women in Science (AWIS) granted its third annual Innovator Award to Tijana Rajh, group leader of the Nanobio Interfaces research group at Argonne National Laboratory?s Center for Nanoscale Materials.
Ob Mikromedizin, Brennstoffzellentechnologie oder RFID - in allen wichtigen Hightech-Feldern ist Mikrosystemtechnik zu finden. Deutschland steht in dieser Zukunftstechnologie weltweit an der Spitze. Damit dies so bleibt, veranstalten das BMBF und der VDE vom 12. bis zum 14. Oktober in Berlin den deutschen Mikrosystemtechnik-Kongress.
An interdisciplinary team of scientists led by Princeton engineers has been awarded a $3 million grant to study how fuel additives made of tiny particles known as nanocatalysts can help supersonic jets fly faster and make diesel engines cleaner and more efficient.
Using nanoparticles, scientists have found a way to preserve membrane proteins intact, enabling detailed analysis of their structure, molecular functions, and interaction with potential anticancer agents.
Using a 'chemical nose' array of nanoparticles and polymers, researchers at the University of Massachusetts Amherst have developed a fundamentally new, more effective way to differentiate not only between healthy and cancerous cells but also between metastatic and nonmetastatic cancer cells.
Monitoring a tumor for weeks or months after the biopsy and tracking its growth and how it responds to treatment would be much more valuable, says Michael J. Cima, who has developed the first implantable device that can do just that.
Scientists at Argonne National Laboratory's CNM Nanophotonics Group have measured how light emission from individual colloidal semiconductor nanocrystals, or quantum dots, is modified when in proximity to smooth metal films.
Four of R&D Magazine's prestigious R&D 100 Awards for 2009, which recognize the 100 most significant proven technological advances of the year, have gone to researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and their colleagues.
