Don’t you just love it when people discover things that can make life better? I know I do.
Take graphene for example. A recent discovery by UCLA researchers lead by Professor Richard Kaner made it easier and cheaper to produce graphene supercapacitor just by using a consumer grade DVD burner. To create a layer of graphene, they put a layer of plastic and graphite oxide on the surface of a DVD disc and use the DVD drive’s Lightscribe laser to create graphene circuits.
The result is a flexible film of graphene, but still able to charge and discharge electricity a hundred, even a thousand, times faster compared to standard batteries. It is also biodegradable, so if you want to dispose of it, just throw it in your garden.
So what are the practical applications of graphene? Using the this new production method, it can be used as an efficient way of storing solar enegy in solar panels. And with its ability to bend and twist, it can be used in flat panel TVs, epaper or even roll-up displays. Plus, it does not contain toxic chemicals, unlike batteries, so it is better for the environment.
