Researchers have observed that the light emitted by a single atom may exhibit much richer dynamics. Strongly interacting with light inside a cavity, the atom modifies the wave-like properties of the light field, reducing its amplitude or phase fluctuations below the level allowed for classical electromagnetic radiation. This is the very first observation of "squeezed" light produced by a single atom.
Based on DMI's successful work under a pair of Phase II Small Business Innovation Research Program contracts designed to develop nanoscale diagnostic technologies that facilitate whole health analysis in a single drop of blood, DMI's rHEALTH sensor has been identified by NASA as a viable approach for performing blood and urine analysis on the International Space Station.
IMRE's patented synthetic cell membranes can be made-to-order, are easier to maintain in a laboratory environment and do not require the lengthy preparation that comes with working on live cell membranes. The synthetic cell membranes mimic the natural functions of cell membranes, such as interacting with drug molecules and antibodies, which is crucial in the drug discovery process.
Whether packing oranges into a crate, fitting molecules into a human cell or getting data onto a compact disc, wasted space is usually not a good thing. Now, Princeton University chemist Salvatore Torquato and colleagues have solved a conundrum that has baffled mathematical minds since ancient times - how to fill three-dimensional space with multi-sided objects other than cubes without having any gaps.
For the next five years, Martin Harmer, director of Lehigh's Center for Advanced Materials and Nanotechnology, will lead a team of scientists from Lehigh, Carnegie-Mellon, Clemson, Illinois and Kutztown universities to determine how the atomic structure of grain-boundary interphases - interphase complexions - affect the mechanical, electrical and thermal properties of a wide range of strategic engineering materials.
Imagine a new genre of tiny implantable sensors, airborne and stationary surveillance cameras and sensors and other devices that operate without batteries on energy collected from the motion of a heart beat and have wireless communications capability. And the power plant for those devices is a "nanogenerator" that could even produce energy to charge an iPod from the movements of a person walking down the street.
Scientists who pioneered a revolutionary 3-D microscope technique are now describing an extension of that technology into a new dimension that promises sweeping applications in medicine, biological research, and development of new electronic devices. Their reports on so-called 4-D scanning ultrafast electron microscopy, and a related technique, appear in two papers.
Researchers have to place objects under study on suitable substrates to obtain a strong enhancement of electromagnetic radiation emitted by single molecules. A simple and cheap method to fabricate substrates for SERS spectroscopy has been discovered at the Institute of Physical Chemistry of the Polish Academy of Sciences. A key role in substrate fabrication play spherical gold aggregates - flower-like micrometer-sized spheres.
The Howard Hughes Medical Institute, the Max Planck Society and the Wellcome Trust announced today that they are to support a new, top-tier, open access journal for biomedical and life sciences research.
Pupils aged 12-14 years old from Kingham-Hill School, Marlborough School, The Oxford Academy, and Oxford High School, took part in the event where they got to learn about the basic science behind applications of nanotechnologies and investigate the properties of nanoscale materials.
