Because of a high Young's modulus and high sound propagation velocity, UNCD materials hold potential for fabricating high-frequency microelectromechanical (MEMS) resonators.
While the researchers can't promise delivery to a parallel universe or a school for wizards, books like Pullman's Dark Materials and JK Rowling's Harry Potter are steps closer to reality now that researchers ...
Recent work at the Department of Energy's SLAC National Accelerator Laboratory and several universities in Sweden and Japan, however, is shedding new light on water's molecular idiosyncrasies, offering insight into its strange bulk properties.
The smallest organisms to use a biological compass are magnetotactic bacteria, however mysteries remain about exactly how these bacteria create their cellular magnets. In a study published online in Genome Research, scientists have used genome sequencing to unlock new secrets about these magnetic microbes that could accelerate biotechnology and nanotechnology research.
Imagine you're a water molecule in a glass of ice water, and you're floating right on the boundary of the ice and the water," proposes Emory University physicist Eric Weeks. "So how do you know if you're a solid or a liquid?
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. The novel NIST device is being developed as the foundation for miniature yet highly accurate gas sensors that can detect chemical and biological agents, industrial leaks and even signs of extraterrestrial life from aboard a planetary probe.
Physicists at the National Institute of Standards and Technology (NIST) have demonstrated sustained, reliable information processing operations on electrically charged atoms (ions). The new work, described in the Aug. 6,...
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. The study, w...
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, scientists at the National Institute of Standards and Technology (NIST) report in Physical Review Letters.
To move your arm or leg, certain muscles need to change shape, to either lengthen or contract. Now scientists have made liquid-crystalline particles that can change shape in a similar way, but which are only micrometers across. Professor Rudolf Zentel and his colleagues at the Universities of Mainz and Strasbourg have prepared these tiny shape-changing materials out of elasticized liquid crystals, taking advantage of a continuous fluidic device for fabrication.
