| Electronics you can wrap around your finger Posted: 10 Feb 2015 10:01 AM PST A new multiferroric film keeps its electric and magnetic properties even when highly curved, paving the way for potential uses in wearable devices. |
| Posted: 10 Feb 2015 07:33 AM PST Gas turbines are used for the production of electricity and in aircraft engines. To increase the life-span of the turbines, they are sprayed with a surface coating. The coating consists of two layers – one of metal to protect against oxidation and corrosion , and one of ceramic to give thermal insulation. The structure of the coating varies greatly, consisting of pores and cracks of different sizes. It is these cracks and pores that largely determine the efficiency of the thermal insulation and the length of the coating life-span. |
| Historic Indian sword was masterfully crafted Posted: 10 Feb 2015 07:33 AM PST The master craftsmanship behind Indian swords was highlighted when scientists and conservationists from Italy and the UK joined forces to study a curved single-edged sword called a shamsheer. The 75-centimeter-long sword from the Wallace Collection in London was made in India in the late eighteenth or early nineteenth century. The design is of Persian origin, from where it spread across Asia and eventually gave rise to a family of similar weapons called scimitars being forged in various Southeast Asian countries. Two different approaches were used to examine the shamsheer: the classical one (metallography) and a non-destructive technique (neutron diffraction). |
| Novel bio-inspired robotic sock promotes blood circulation and prevents blood clots in legs Posted: 10 Feb 2015 02:08 AM PST Innovative robotic sock, which mimics tentacle movements of corals, can benefit bedridden or immobile patients. |
| Bringing texture to your flat touchscreen with virtual bumps Posted: 09 Feb 2015 01:14 PM PST What if the touchscreen of your smartphone or tablet could touch you back? Researchers now report a discovery that provides insight into how the brain makes sense of data from fingers. When people draw their fingers over a flat surface with two 'virtual bumps,' the researchers found that, under certain circumstances, the subjects feel only one bump when there really are two. And the researchers can explain why the brain comes to this conclusion. |
