The special SESAM system, a high performance version of the LIBRA® 200 transmission electron microscope series from Carl Zeiss SMT, has been in use at the Stuttgart Center for Electron Microscopy (StEM) of the Max-Planck-Institute for Metals Research (MPI-MF) for the past 10 months.
Put steel under a powerful microscope, revealing its microstructure, and prepare to be surprised. Known for its strength, the metal will appear pitted and pocked."It is intrinsic to the material," says Carolyn Aita, a Wisconsin Distinguished Professor at the University of Wisconsin-Milwaukee (UWM). "A pit can begin to develop from a physiochemical defect in the steel itself."
By manipulating the way tiny droplets of fluid dry, Cornell researchers have created an innovative way to make and pattern nanoscale wires and other devices that ordinarily can be made only with expensive lithographic tools. The process is guided by molds that "stamp" the desired structures.
With the appearance of gracefully swooping beams of light or a colorful array of feathers, a dazzling photo of Pleurosigma (marine diatoms) has won the 2008 Nikon Small World Photomicrography Competition. Michael Stringe...
Charles Rosenblatt, professor of physics and macromolecular science at Case Western Reserve University, and his research group have developed a method of 3D optical imaging of anisotropic fluids such liquid crystals, with volumetric resolution one thousand times smaller than existing techniques. A research paper detailing the team's findings appeared in the September 21 advanced online publication of Nature Physics. The print version will be available soon.
A new research field called transformation optics may usher in a host of radical advances including a cloak of invisibility and ultra-powerful microscopes and computers by harnessing nanotechnology and "metamaterials."
The country's most elaborate travel-wear keeps the body cool in hot helicopter cabins, but transforms into a heat-retaining suit if the helicopter should fall into the sea.
A revolutionary new gold nanorod manufacturing method has been developed at Nanopartz where their patent pending gold nanorods are proving their ability to be the future in-vivo nanoparticle for the detection and treatme...
University of Arizona scientists experimenting with some of the coldest gases in the universe have discovered that when atoms in the gas get cold enough, they can spontaneously spin up into what might be described as quantum mechanical twisters or hurricanes.
Researchers at the National Institute of Standards and Technology (NIST) and JILA, a joint institute of NIST and the University of Colorado (CU) at Boulder, have made the first tunable "noiseless" amplifier. By significantly reducing the uncertainty in delicate measurements of microwave signals, the new amplifier could boost the speed and precision of quantum computing and communications systems.
