Scientists can detect the movements of single molecules by using fluorescent tags or by pulling them in delicate force measurements, but only for a few minutes. A new technique by Rice University researchers will allow them to track single molecules without modifying them - and it works over longer timescales.
Not much is known about what happens to this abundant element under high-pressure conditions when it transforms from one state to another. Using quantum simulations, scientists were able to uncover these phase transitions in the laboratory.
Worldwide nanomaterials researchers seeking the most appropriate way to solve difficult optimization problems typical of nanomaterials research can get easy to follow step-by-step instructions on how to select the best-suited local or global optimization routines, from the Numerical Algorithms Group (NAG) Library, by making use of the Decision Trees for optimization.
Brookhaven National Laboratory is constructing the world's most brilliant light source, the National Synchrotron Light Source II (NSLS-II). In a recent decision, DOE has approved a new project to begin conceptual design of NSLS-II experimental tools, named NEXT.
Professor Dr. Matthias Beller vom Leibniz-Institut fuer Katalyse in Rostock, der am 29. August 2010 anlaesslich des 3rd EuCheMS Chemistry Congress in Nuernberg als erster Wissenschaftler mit dem neu geschaffenen European Sustainable Chemistry Award ausgezeichnet wird, eroeffnet am 29. Juni in Rostock das Symposium 'Catalysis and Photochemistry for Energy Technologies'.
Liquid water, as well as other liquids, exhibits characteristic vibrations upon excitation with electromagnetic waves over a wide spectral range. At frequencies which correspond to infrared light, vibrational motions within single molecules can be observed.
A surprising MIT laboratory finding about the behavior of a thin sheet of material - less than a thousandth of the thickness of a human hair - could lead to improved ways of studying the behavior of electrodes and perhaps ultimately to improvements in the rate of power production from one type of fuel cell.
The NanoKTN is pleased to announce the first event from its NanoMed focus group. The event will examine areas where nanotechnology is already improving clinical practice and also where the technology will be impacting healthcare in the near and distant future.
Researchers at the nanotechnology research centre imec (Leuven, Belgium) have demonstrated biosensors based on novel nanostructure geometries that increase the sensitivity and allow to detect extremely low concentrations of specific disease markers.
A sensitive measuring device must not be dropped - because this usually destroys the precision of the instrument. A team of researchers including scientists from the Max Planck Institute of Quantum Optics has done exactly this, however. And the researchers want to use this experience to make the measuring instrument even more sensitive.
