An international team of researchers has developed a numerical modeling technique to study specific types of particles called excitons, which consist of a positively and a negatively charged electron and hole, respectively.
Scientists at the RIKEN Advanced Science Institute in Wako, and co-workers at the National Academy of Sciences of Ukraine (NASU), have shown for the first time that the Casimir force has a complex dependence on temperature.
The House Science and Technology Committee today introduced legislation that highlights the growing attention on Capitol Hill to the need to strengthen federal efforts to learn more about the potential environmental, health and safety (EHS) risks posed by engineered nanomaterials.
Ever since the 1966 Hollywood movie, doctors have imagined a real-life Fantastic Voyage a medical vehicle shrunk small enough to 'submarine' in and fix faulty cells in the body. Thanks to new research by Tel Aviv University scientists, that reality may be only three years away.
A handheld, ultra-portable device that can recognize and immediately report on a wide variety of environmental or medical compounds may eventually be possible, using a method that incorporates a mixture of biologically tagged nanowires onto integrated circuit chips, according to Penn State researchers.
After being the first to demonstrate the feasibility of such a device by constructing a prototype in 2006, a team of Duke University engineers has produced a new type of cloaking device, which is significantly more sophisticated at cloaking in a broad range of frequencies.
Rapid, easy and affordable tests for cancer, avian flu and other infectious diseases move a step closer to patients as DYAMED Biotech Pte Ltd (Dyamed) licenses a unique all-inone automated diagnostic system called MicroKit from the Institute of Bioengineering and Nanotechnology in Singapore.
Wissenschaftlern ist es zum ersten Mal gelungen, die Verteilung von Oberflaechenplasmonen - das sind elektronische Dichteschwankungen an der Oberflaeche von Metallen - auf Gold-Nanoteilchen mit Energiefilterungs-Elektronenmikroskopie zu messen.
University of Toronto quantum physicists Jeff Lundeen and Aephraim Steinberg have shown that Hardy's paradox, a proposal that has confounded physicists for over a decade, can be confirmed and ultimately resolved, a task which had seemingly been impossible to perform.
The ability of the Food and Drug Administration (FDA) to regulate the safety of dietary supplements using nanomaterials is severely limited by lack of information, lack of resources and the agency's lack of statutory authority in certain critical areas, according to a new expert report released by the Project on Emerging Nanotechnologies (PEN).
