| Posted: 17 Feb 2013 10:42 AM PST To make fuel cells more economical, engineers want a fast and efficient iron-based molecule that splits hydrogen gas to make electricity. Researchers now report such a catalyst. It is the first iron-based catalyst that converts hydrogen directly to electricity. The result moves chemists and engineers one step closer to widely affordable fuel cells.  |
| Posted: 17 Feb 2013 05:52 AM PST Engineers have created a more efficient way to catch rainbows, an advancement in photonics that could lead to technological breakthroughs in solar energy, stealth technology and other areas of research.  |
| Posted: 17 Feb 2013 05:52 AM PST Physicists have demonstrated extremely flexible organic semiconductors that withstood multiple bending cycles in which the devices were rolled to a radius as small as 200 micrometers. The technology holds promise for making low-cost flexible electronics -- conceivably video displays that bend like book pages or roll and unroll like posters, or wearable circuitry sewn into uniforms or athletic wear.  |
| Shifting sands: Force is the key to granular state-shifting Posted: 17 Feb 2013 05:50 AM PST Ever wonder why sand can both run through an hourglass like a liquid and be solid enough to support buildings? It's because granular materials -- like sand or dirt -- can change their behavior, or state. Researchers have found that the forces individual grains exert on one another are what most affect that transition.  |
| Breakthrough architecture for quantum computers proposed Posted: 17 Feb 2013 05:49 AM PST Scientists have proposed a new computational model that may become the architecture for a scalable quantum computer.  |
| 'Bionic proteins': Nano-machines recreate protein activities Posted: 17 Feb 2013 05:49 AM PST Physicists have developed nano-machines which recreate principal activities of proteins. They present the first versatile and modular example of a fully artificial protein-mimetic model system. These "bionic proteins" could play an important role in innovating pharmaceutical research.  |
| Posted: 17 Feb 2013 05:41 AM PST Infrared sensing might be built into a whole-body prosthesis for paraplegics so patients wearing the "exoskeleton" could have sensory information about where their limbs are and how objects feel when they touch them.  |
| Tough, light and strong: Lessons from nature could lead to the creation of new materials Posted: 14 Feb 2013 11:18 AM PST In a sweeping review of the field of bio-inspired engineering and biomimicry, two engineers have identified three characteristics of biological materials that they believe engineers would do well to emulate in human-made materials: light weight, toughness and strength.  |
| Combining quantum information communication and storage Posted: 14 Feb 2013 04:54 AM PST Researchers in Finland have successfully connected a superconducting quantum bit, or qubit, with a micrometer-sized drum head. Thus they transferred information from the qubit to the resonator and back again.  |
