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...

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 Lab Glass 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...

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...

Researchers at the California Institute of Technology (Caltech) have developed a way to make some notoriously brittle materials ductile"”yet stronger than ever"”simply by reducing their size. The work, by Dongchan Jang, senior postdoctoral scholar, and Julia R. Greer, assistant professor of materials science and mechanics at Caltech, could eventually lead to the development of innovative, superstrong, yet light and damage-tolerant materials. These new materials could be used as...

By stretching a foam ribbon and dissecting leaves, a mathematical model emerges Applied mathematicians dissected the morphology of the plantain lily (Hosta lancifolia), a characteristic long leaf with a saddle-like arc midsection and closely packed ripples along the edges. The simple cause of the lily's fan-like shape"”elastic relaxation resulting from bending during differential growth"”was revealed by using an equally simple technique, stretching foam ribbons. Haiyi Liang, a...

Crash tests often produce startling results. A new simulation process which factors in deformation during production as well as preliminary damage can predict the results of a crash test more accurately than ever. There are components that save lives: if a car rolls over during an accident, the "ËœB-pillar' plays a key role. It forms one of the connections between the floor and roof of the vehicle and is designed to prevent the passenger cell from deforming too much. The materials...
