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).
Researchers investigated the crystallization of calcium carbonate, known commonly as chalk, and found that stable nanoclusters form in water with a small quantity of dissolved calcium carbonate - not how it was assumed to happen in the past.
Representatives from GlaxoSmithKline, AstraZeneca, University of Glasgow, Imperial College London and the London Centre for Nanotechnology come together to discuss the increasingly important convergence of Nanotechnology and Life Sciences in London on 11th February
Am 19. Februar 2009 treffen Experten aus Wissenschaft, Politik und Wirtschaft in Berlin aufeinander, um die heute schon bedeutende Rolle der Nanotechnologie in der ostdeutschen Forschungs- und Wirtschaftslandschaft zu diskutieren.
Despite considerable progress in modern chemotherapy, there remains a large demand for innovative anti-tumor agents. A new approach involves modeling the pharmacological properties of established drugs with organometallic fragments.
A new EU-funded research project is set to lead the way in creating top-quality healthcare standards for in vitro diagnostics, an area of medicine that could be of vital importance to personalised medicine.
Physicists have proposed a recipe for turning ultracold 'boson' atoms - the ingredients of Bose-Einstein condensates - into a 'supersolid', an exotic state of matter that behaves simultaneously as a solid and a friction-free superfluid.
While exploring the properties of polymer formation, a team of scientists at the National Institute for Standards and Technology (NIST) has made a fundamental discovery about these materials that could improve methods of creating the stable crystalline films that are widely used in electronics applications.
Researchers at NIST describe a new method for creating gas detectors so sensitive that some day they may be able to register these tiny emissions from a single cell, providing a new way to determine if drugs or nanoparticles harm cells or to study how cells communicate with one another.
A new study from the National Institute of Standards and Technology (NIST) and Rice University offers an inexpensive process that gets nanotubes to obediently line themselves up - that is, self-assemble - in neat rows, more like ducks.
Using a new technique based on terahertz (THz) spectroscopy, scientists at the National Institute of Standards and Technology (NIST) have recently taken the first step toward revealing the hidden machinations of biomolecules in water.
