'Artificial Leaf'-A New Energy Source

Researchers from Massachusetts Institute of Technology have invented the world's first artificial leaf that can turn water into hydrogen and oxygen with the help of sunlight without needing any external connections, is seen with some real leaves, which also convert the energy of sunlight directly into storable chemical form. Researchers led by MIT professor Daniel Nocera have produced something they’re calling an “artificial leaf”: Like living leaves, the device can turn the energy of sunlight directly into a chemical fuel that can be stored and used later as an energy source. In this a silicon solar cell with different catalytic materials bonded onto its two sides which needs no external wires or control circuits to operate. Bound onto the silicon is a layer of a cobalt-based catalyst, which releases oxygen, a material whose potential for generating fuel from sunlight was discovered by Nocera and his co-authors in 2008. The other side of the silicon sheet is coated wit

Graphene, The next Generation Processor

Graphene, the world's thinnest and toughest material, could spur the development of next generation computer chips, besides revolutionising materials science.Its amazing properties open the way to bendable touch screen phones and computers, lighter aircraft, paper thin HD TV sets and lightning-quick net connections, and more. Graphene is an allotrope of carbon, whose structure is one-atom-thick planar sheets of sp2-bonded carbon atoms that are densely packed in a honeycomb crystal lattice or arranged in a hexagonal pattern resembling chicken wire. In graphite, many flat graphene sheets are stacked together. The term graphene was coined as a combination of graphite and the suffix -ene by Hanns-Peter Boehm, who described single-layer carbon foils in 1962. Graphene is most easily visualized as an atomic-scale chicken wire made of carbon atoms and their bonds. The crystalline or "flake" form of graphite consists of many graphene sheets stacked together.Graphene transi

Linux Foundation to launch Mobile OS-Tizen

Linux Foundation and Limo Foundation aiming to launch the brand new mobile os Tizen to compete with Android,Apple and Symbian OSes. It will be a Web - centric operating system for smartphones, tablets, smart TVs, netbooks and in-vehicle infotainment systems. The Linux Foundation will host the project, and plans an initial release in the first quarter of 2012, enabling the first devices to come to market in mid-2012, it said. Tizen is an open source, standards-based software platform supported by leading mobile operators, device manufacturers, and silicon suppliers for multiple device categories, including smartphones, tablets, netbooks, in-vehicle infotainment devices, smart TVs, and more. Tizen will offer an innovative operating system, applications, and a user experience that consumers can take from device to device. The goal is to develop an OS that makes it easy to a run and develop browser-based applications such as on HTML-5, where most mobile OSes today focus on running a
