| 70-foot-long, 52-ton concrete bridge survives series of simulated earthquakes Posted: 16 Jul 2014 11:13 AM PDT A 70-foot-long, 52-ton concrete bridge survived a series of earthquakes in the first multiple-shake-table experiment in the University of Nevada, Reno's new Earthquake Engineering Lab, the newest addition to the world-renowned earthquake and seismic engineering facility. |
| Efficient structures help build a sustainable future Posted: 16 Jul 2014 08:27 AM PDT Researchers have found that the selection of steel cable structural system for long spans has considerably less environmental impact than a steel truss system to achieve the same structural requirements, through the entire life cycle of the structure. "Thoughtful selection, by the architectural engineer, in the initial stages of the design process, can reduce environmental impact related to the construction process," said one author of the new study. |
| An anti-glare, anti-reflective display for mobile devices? Posted: 16 Jul 2014 08:27 AM PDT If you've ever tried to watch a video on a tablet on a sunny day, you know you have to tilt it at just the right angle to get rid of glare or invest in a special filter. But now scientists are reporting that they've developed a novel glass surface that reduces both glare and reflection, which continue to plague even the best mobile displays today. |
| Supercomputers reveal strange, stress-induced transformations in world's thinnest materials Posted: 16 Jul 2014 06:57 AM PDT Interested in an ultra-fast, unbreakable, and flexible smart phone that recharges in a matter of seconds? Monolayer materials may make it possible. These atom-thin sheets -- including the famed super material graphene -- feature exceptional and untapped mechanical and electronic properties. But to fully exploit these atomically tailored wonder materials, scientists must pry free the secrets of how and why they bend and break under stress. Supercomputer simulations have revealed unexpected transitions in graphene and other promising super materials under strain. |
| Extending Moore's Law: Shrinking transistor size for smaller, more efficient computers Posted: 15 Jul 2014 01:59 PM PDT Over the years, computer chips have gotten smaller thanks to advances in materials science and manufacturing technologies. This march of progress, the doubling of transistors on a microprocessor roughly every two years, is called Moore's Law. But there's one component of the chip-making process in need of an overhaul if Moore's law is to continue: the chemical mixture called photoresist. In a bid to continue decreasing transistor size while increasing computation and energy efficiency, chip-maker Intel has partnered with researchers to design an entirely new kind of resist. |
| Posted: 15 Jul 2014 12:45 PM PDT A three-dimensional porous nanostructure would have a balance of strength, toughness and ability to transfer heat that could benefit nanoelectronics, gas storage and composite materials that perform multiple functions, according to engineers. |
