  • That's hot: Heat-based recording could boost magnetic drive speed, performance

    Magnetic fields are pretty nifty for levitating stuff, carving sponge-like thingamajigs and, of course, data storage. But an international team led by the University of York in the UK has figured out a way to replace magnetic fields for the latter by using ultra-short heat pulses instead. Conventional thinking typically dictates that an external magnetic field is required to store data on a magnetic medium. By using heat, however, researchers were able to record terabytes of information per second in a way that is also more energy-efficient compared to current hard drive technology. As for the time it'll take for the tech to make it to market, well, we have a feeling it won't be as fast.

  • LCDs can be transformed from e-waste to infection fighters, says new research

    Researchers at the University of York have discovered a possible use for discarded LCDs which should come as a relief to anyone familiar with the world's rampant e-waste problem. According to the report, which will be presented today at the Green Chemistry and Engineering Conference in Washington, D.C., a process of heating, then cooling and dehydrating the PVA (polyvinyl-alcohol, the key component of LCDs) with ethanol produces a surface area of mesoporous material with great potential for use in biomedicine. The resultant product's anti-microbial properties can now be enhanced by adding silver nanoparticles, producing something which is anti-bacterial and can kill things like E.coli. The potential application of course, is that hospital surfaces could be made of it in the future. This is just one (major) step in a long-term project, so don't expect to see it in real life anytime soon.
