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.
Parents who yell at their kids to "go out and play" this summer may want to follow their own advice. A new study from U.S. Department of Energy's Lawrence Berkeley National Laboratory has found that bone aging can be accelerated from a lack of vitamin D.
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.
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.
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.
Metallic glass thatâ€™s stronger and lasts longer.
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...
