Nanowire Manipulation Could Lead to HandHeld Supercomputers

first_imgResearchers have been working on nanowires and microchips so tiny that they could be used to build supercomputers that could fit in the palm of your hand. Hopefully, the nanowires will eventually lead to small, powerful gadget such as hand-held PCs, mobile phones as powerful as laptops, and medical advances. The Columbia Supercomputer at NASA´s Advanced Supercomputing Facility at Ames Research Center. Designer proteins form wires and lattices on mineral surface The group of engineers, with members from the University of Edinburgh in Scotland, the Karlsruhe Institute of Technology in Germany and the University of Rome in Italy, will have their results published in an upcoming issue of Science. The researchers studied the behavioral properties of nanowires—which are more than 1,000 times thinner than a human hair—and investigated how the wires react and respond to exterior forces compared with conventional wires. “What we found is when we made these wires smaller and smaller they started to behave in a very funny way,” researcher Michael Zaiser told the BBC News.To control the strange behavior, the researchers developed a computer program that allows engineers to predict when problems might arise with the wires, and how to avoid them.Using this understanding, the group found ways to ensure that tiny wires in electronics hardware will be able to retain their efficiency, which is essential for the power requirements in scaled-down supercomputers. The wires can then be used to fabricate tiny microchips and processors for electronics applications.”This will help to make small devices much more powerful in the future,” Zaiser said. “Holding a supercomputer in the palm of your hand will one day be possible – and we are going to make sure all the wires are in the right place.”Via: BBC News Citation: Nanowire Manipulation Could Lead to Hand-Held Supercomputers (2007, October 22) retrieved 18 August 2019 from https://phys.org/news/2007-10-nanowire-hand-held-supercomputers.html This document is subject to copyright.

Of dull skies and not so dull London

first_imgThe launch was followed by an in-depth conversation between the author and Sen. Prof. Nirmal Kanti Bhattacharjee, former Director of National Book Trust and presently Director, Niyogi Books summed up the proceedings.The book, published by Niyogi Book, highlights the struggle that an Indian student faced in post-war London—between two cultures, two value systems, two ways of life—and love. “We’re the lost generation,” he cries in anguish. The author emphasizes that the fifties heralded a swinging era and brings out on how a naïve Indian student copes with this over-heated milieu. It is one of the few books from the subcontinent to explore post-war England through the eyes of an Indian who grew up under British rule. Also Read – ‘Playing Jojo was emotionally exhausting’The Copper Sky is the story of Amar Das who arrives to study at the London School of Economics in 1950s. The release from the war-torn skies and the daily threat of death had unleashed a tide of unprecedented pleasure-seeking, which swept over hidebound English society. Amar realizes that gone was the Victorian prudery the British rulers had exported to middle-class India, as he stumbles over coupled bodies in his walk through Hyde Park. Casting a dark shadow over this, though, are his bitter memories of British rule and anguish at having been treated as second-class citizen in his own country. The author, Abhijit Gupta retired from a multinational and a subsequent HR consultancy firm submitted to a lifelong desire to write, creating a novel influenced by the three eventful years he spent getting his degree at the London School of Economics. In those years he found a new intellectual and emotional liberation and grew to love London for it.last_img read more

KMC looks to bring up electric charging stations across city

first_imgKolkata: As a major stride in its effort to turn Kolkata into a Green City, the Kolkata Municipal Corporation (KMC) is planning to come up with electric vehicle (EV) charging stations, in collaboration with CESC. The effort will encourage the use of more electric vehicles, which will contribute significantly in bringing down air pollution.”We are holding talks with CESC and will soon come up with electric vehicle charging stations in spaces under flyovers or parking lots, wherever there will be availability of space. Our aim is to encourage the citizens to use electric vehicles. The vehicular pollution is on the rise in the city and if people use electric vehicles, pollution will be reduced,” said Mayor Firhad Hakim, adding that he will be constantly striving towards promotion of e-vehicles. Also Read – Rain batters Kolkata, cripples normal lifeHakim has instructed the officials of the civic body to collaborate with CESC and identify places in the city where there is possibility of setting up such charging stations.
