Joseph Federico, VP of NJ Micro Electronic Testing, NJ, Announced Expansion of Its Laboratory Testing Services to Include Tensile Testing Clifton, NJ (PRWEB) August 31, 2011 Joseph Federico, Vice President of NJ Micro Electronic Testing, is proud to announce the expansion of its laboratory testing services to include tensile testing for a spectrum of materials before the product is used in industry. This testing will provide vital data on elongation, yield point, modulus and tensile...

Rice University researchers surprised to see twin-induced brittle-like fractures in gold nanowires Thin gold wires often used in high-end electronic applications are wonderfully flexible as well as conductive. But those qualities don't necessarily apply to the same wires at the nanoscale. A new study from Rice University finds gold wires less than 20 nanometers wide can become "brittle-like" under stress. It appears in the journal Advanced Functional Materials. The paper by Rice...

DENVER, Aug. 9, 2011 /PRNewswire/ -- The American Psychological Association says stress costs corporations $300 billion a year in absences, medical costs, lost productivity and turnover. But this doesn't have to happen. "You perceive situations as threatening every day. You forgot you have the ability to shift your perceptions and your reactions to any situation which makes all of the difference in the outcome," says stress relief expert Lauren E. Miller, who recently launched her 4th book,...

Hohai University in Nanjing has established a research tradition in hydraulic engineering over the last 95 years. During this time, Hohai has become a first class institution of higher education that focuses on a wide range of engineering subjects including civil engineering and water resources, which are of particular interest.China's hydropower development occurs mainly in the high mountains and canyons of the Qinghai-Tibet plateau in the southwestern provinces. Because of long term...

Lynn Yarris, Berkeley LabGlass stronger and tougher than steel? A new type of damage-tolerant metallic glass, demonstrating a strength and toughness beyond that of any known material, has been developed and tested by a collaboration of researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab)and the California Institute of Technology. What's more, even better versions of this new glass may be on the way."These results mark the first use of a...

ST. LOUIS, Dec. 2, 2010 /PRNewswire/ -- Sigma Life Science, the innovative biological products and research services business of Sigma-Aldrich® Corporation (Nasdaq: SIAL), today announced that its genetically modified reporter cell lines - based on the CompoZr zinc finger nuclease (ZFN) technology - takes the silver medal position in The Scientist magazine's Top Ten Innovations for 2010. This latest award continues Sigma Life Science's track record of success in the magazine's...

Materials scientists have known that a metal's strength (or weakness) is governed by dislocation interactions, a messy exchange of intersecting fault lines that move or ripple within metallic crystals. But what happens when metals are engineered at the nanoscale? Is there a way to make metals stronger and more ductile by manipulating their nanostructures?Brown University scientists may have figured out a way. In a paper published in Nature, Huajian Gao and researchers from the University of...

In research published in the March 4 issue of the journal Nature, Northeastern University physicists have pioneered the development of large-scale computer simulations to assess how cracks form and proliferate in materials ranging from steel and glass to nanostructures and human bones. For years, scientists have tried to understand the propagation of cracks and how they affect the materials in which they form, said Alain Karma, distinguished physics professor and lead investigator on the...

Johns Hopkins researchers have discovered that, under the right conditions, newly developed nanocrystalline materials exhibit surprising activity in the tiny spaces between the geometric clusters of atoms called nanocrystals from which they are made.This finding, detailed recently in the journal Science, is important because these nanomaterials are becoming more ubiquitous in the fabrication of microdevices and integrated circuits. Movement in the atomic realm can affect the mechanical...
