Julich scientists have succeeded in precisely measuring atomic spacings down to a few picometres using new methods in ultrahigh-resolution electron microscopy. This makes it possible to find out decisive parameters determining the physical properties of materials directly on an atomic level in a microscope. Knut Urban from Forschungszentrum Julich, a member of the Helmholtz Association, reports on this in the latest issue (25 July) of the scientific high-impact journal Science.
Although order is pleasing to the eye, it can quickly become boring. In Islamic architecture therefore, decoration often follows a strict yet aperiodic pattern. Similar structures also form in certain materials, called quasicrystals. Physicists from the University of Stuttgart and the Max Planck Institute of Metals Research have succeeded in trapping a monolayer of colloidal particles, tiny plastic spheres, in a laser lattice with an aperiodic structure.
Taking images of ice a few nanometers thick as it forms bulk ice was supposed to be impossible. A scanning tunneling microscope (STM) shouldn t work with ice because STMs create images by relying on conducting current, which runs contrary to one of ice's basic properties - insulation.
CN Probes, an emerging nanotech solutions provider, has executed an agreement with a leading MEMS Foundry (contract manufacturer). This agreement puts CN Probes closer to ramping up full-scale production and launch of CN...
Research scientists at Columbia University's Fu Foundation School of Engineering and Applied Science have achieved a breakthrough by proving that the carbon material graphene is the strongest material ever measured.
Sandia National Laboratories will demonstrate a new hyperspectral confocal fluorescence microscope Friday, Aug. 8 from 9 a.m.-2 p.m. MDT in Bldg. 897 on Kirtland Air Force Base. This patent-protected and patent-pending t...
Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley have performed the first scanning tunneling spectroscopy of graphene flakes equipped with a "gate" electrode.
Alabama State University is gaining a powerful tool that will help faculty and students perform world-class research in nanobiotechnology.The Center for Nanobiotechnology Research at ASU recently purchased a $72,000 Atomic Force Microscope (AFM). This was made possible through part of a $4.9 million grant received in 2007 from the National Science Foundation.
Carl Zeiss SMT yesterday was presented with a 2008 Editors' Choice Best Product Award from Semiconductor International magazine in recognition of the revolutionary break-through performance of its ORION(TM) Helium Ion Microscope. The Best Product Awards are presented annually to acknowledge those products that deliver the level of excellence needed to succeed in today's and tomorrow's semiconductor industry.
What is there to see inside a magnet that's smaller than the head of a pin? Quite a lot, say physicists who've invented a new kind of MRI technique to do just that. The technique may eventually enable the development of extremely small computers, and even give doctors a new tool for studying the plaques in blood vessels that play a role in diseases such as heart disease.
