Getting the Small Picture
Apr 1, 2003 — Anadigics Inc. of Warren, N.J., is a semiconductor company that helps provide the gift of gab -- and data, too. Its gallium-arsenide integrated circuits are used in both wired and wireless telecommunications systems, and although its products...
Near-Field Raman Offers 25-nm Resolution
Apr 1, 2003 — Researchers at the University of Rochester in New York, Portland State University in Oregon and Harvard University in Cambridge, Mass., have reported a spatial resolution of 25 nm in their study of the near-field Raman imaging of single-walled...
Optical Fibers Test DNA
Apr 1, 2003 — Detecting very small quantities of chemical or biological material for security and defense applications is fraught with problems, including the generation of false-positives and -negatives as a result of a lack of sensitivity or accidental...
Doped Glass Enables Tiny Bar Codes
Mar 1, 2003 — The ability to label chemicals, biological samples, explosives and currency with invisible ID tags would lead to numerous security and safety applications. Now scientists at Corning Inc. in Corning, N.Y., have built bar codes from microscopic slices...
Tracking Nanoposition Advances
Mar 1, 2003 — What works in the microworld very often doesn’t work in nanopositioning applications such as nano-imprinting, scanning microscopy, microlithography and automated alignment. End users will often need to rethink positioning strategies, including...
Tunneling Electrons Stimulate Individual Molecules
Mar 1, 2003 — Using a scanning tunneling microscope, a research team at the University of California, Irvine, has induced photoemission in individual porphyrin molecules on an aluminum oxide film, yielding fluorescence patterns that depend on the molecular...
Daily News Briefs
Feb 20, 2003 — Photon Dynamics Inc. has named Jeffrey A. Hawthorne as senior vice president to manage its flat-panel display business. He replaces Bernard T. Clark, who has resigned. . . . Provectus Pharmaceuticals Inc. announced it has received US patent No....
Nanodevice Breaks 1-GHz Barrier
Feb 13, 2003 — PASADENA, Calif., Feb. 13 -- Wristwatch cellular phones and space probes the size of baseballs would certainly have some eager customers, but both are still the stuff of science fiction. Nonetheless, physicists are making strides in the sort of...
CCD Imaging: When Every Pixel Counts
Feb 1, 2003 — With CCDs, production of a quality image remains their selling point, whether the sensors are used with a microscope, the Advanced Camera for Surveys (ACS) on the Hubble Space Telescope or your cell phone. In all cases, though, time is also of the...
Experiment, Theory Expose Light through Slits
Feb 1, 2003 — Using near-field scanning optical microscopy and finite difference time-domain modeling, scientists at Academia Sinica in Taipei, Taiwan, have investigated the propagation of light through a slit. Their findings confirm that the transmittance of...
