From the production of tougher, more durable smart phones and other electronic devices, to a wider variety of longer lasting biomedical implants, bulk metallic glasses are poised to be  mainstay materials for the 21st Century. Featuring a non-crystalline amorphous structure, bulk metallic glasses can be as strong or even stronger than steel, as malleable as plastics,  conduct electricity and resist corrosion. These materials would seem to have it all save for one problem: they are often...

Sunshine Vitamin Can Help Keep Your Bones Healthy

Brett Smith for redOrbit.com - Your Universe Online Parents who yell at their kids to "go out and play" this summer may want to follow their own advice. A new study from US Department of Energy's Lawrence Berkeley National Laboratory has found bone aging can be accelerated from a lack of vitamin D. Synthesized when the skin is exposed to the sun's rays, vitamin D conveys numerous other health benefits including lowering the risks of multiple sclerosis and rheumatoid arthritis in women....

Real-Time CT-Scan Test Rig For Ceramic Composites At Ultrahigh Temperatures Developed
2012-12-10 16:41:08

Lawrence Berkeley National Laboratory Advanced ceramic composites can withstand the ultrahigh operational temperatures projected for hypersonic jet and next generation gas turbine engines, but real-time analysis of the mechanical properties of these space-age materials at ultrahigh temperatures has been a challenge — until now. Researchers with the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab) have developed the first testing facility...

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...

Three-quarters of surgical patients would consider allowing a competent unsupervised trainee junior doctor perform their entire operation if it meant they could have it done more quickly, according to a survey published in the September issue of BJUI. The responses were high regardless of how complex the surgery was, with 80 per cent of those facing minor surgery and 68 per cent of those facing major surgery saying they would consider the suggestion. Eighty patients took part in the survey at...

Metallic glass that's stronger and lasts longer The normal structure of metals is crystalline. Glass, on the other hand, is amorphous. But it's possible to make amorphous forms of metal, metallic glasses, which can be remarkably strong, having many properties equal to or better than their crystalline metal cousins. The catch is that bulk metallic glasses are highly susceptible to fatigue, a severe problem for their use as structural materials. Now researchers at the U.S. Department of...

Biomimicry "“ technological innovation inspired by nature "“ is one of the hottest ideas in science but has yet to yield many practical advances. Time for a change. Scientists with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have mimicked the structure of mother of pearl to create what may well be the toughest ceramic ever produced.The roughness of the alumina/PMMA hybrid ceramic controls the strength of the interfaces, which is critical in...
