Squeezed light from single atoms

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.

Synthetic cell membranes for faster and cheaper drug development

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.

Researchers solve problem filling space - without cubes

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.

Lehigh University leads Department of Defense MURI grant for atomic-scale interphase research

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.

ACS Podcast: Tiny generator powers wireless device

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.

Moving microscopic vision into another new dimension

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.

Gold microflowers to enhance signals from molecules

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.
