An experimental atomic clock based on ytterbium atoms is about four times more accurate than it was several years ago, giving it a precision comparable to that of the NIST-F1 cesium fountain clock, the nation's civilian time standard.
Researchers at the National Institute of Standards and Technology (NIST) have developed a new calibration technique that will improve the reliability and stability of one of NIST's most versatile technologies, the microhotplate.
As a result of a major inter-laboratory study, the standards body ASTM International has been able to update its guidelines for a commonly used technique for measuring the size of nanoparticles in solutions.
Researchers in the United States and Spain have discovered that a tool widely used in nanoscale imaging works differently in watery environments, a step toward better using the instrument to study biological molecules and structures.
Growing - and precisely aligning - microscopic, spear-shaped zinc oxide crystals on a surface of single-crystal silicon, researchers at Missouri University of Science and Technology may have developed a method to make more efficient solar cells.
JEOL, a leading supplier of high resolution, high performance Scanning Electron Microscopes (SEM) and atomic resolution Transmission Electron Microscopes (TEM), has developed two new publications that explain theory and operation of the SEM for routine imaging and elemental analysis.
Water is familiar to everyone - it shapes our bodies and our planet. But despite this abundance, the molecular structure of water has remained a mystery, with the substance exhibiting many strange properties that are still poorly understood. Recent work, however, is shedding new light on water's molecular idiosyncrasies, offering insight into its strange bulk properties.
Duke University engineers say they can for the first time control all the degrees of the particle's motion, opening up broad possibilities for nanotechnology and device applications. Their unique technology should make it more likely that Janus particles can be used as the building blocks for a myriad of applications, including such new technologies as electronic paper and self-propelling micromachines.
An international team of researchers from the Netherlands, Russia and Austria discovered that monolayer coverage and channel length set the mobility in self-assembled monolayer field-effect transistors (SAMFETs).
Das Institut fuer Photonische Technologien (IPHT) verstaerkt seine Aktivitaeten im Bereich der spektralen Bildgebung. Im Rahmen des Verbundprojektes CHEMOPRAEVENT will das Institut mit Hilfe neuester optischer Methoden die Ursache der Nebenwirkungen von Chemotherapeutika untersuchen.
