Now OLEDs! Is coming
The flexible organic light emitting diodes (OLEDs) has been developed, which may lead to a television as thin as common magazine and so much flexible that it may be roll as a sheet of paper!
OLEDs have a thin layer of light producing organic molecules coated on a glass surface which gives out light when an electric supply is given to it. Scientists are trying to make the television screen of such materials. It will be interesting to know that the screens made of this material do not need back light and have a nice black/white contrast than liquid crystal. A very much wide television of this material will consume less electricity in comparison to the normal smaller televisions.
The screen made of OLEDs material can be printed onto flexible surface by using an ink jet printer. In this way the total cost will be reduced than the liquid crystal screens.
If OLEDS may be printed on textiles, they may lead to illuminated dresses which will give out different changing shades of light. The dresses will be supplied electrical power by small batteries that may be put in pockets. A big change may be expected in electronics and textile as well if the material is available in the market. OLEDs can enlighten electronic displays on carpets, TVs, textiles, and curtain. The ladies of future will surely shine and sparkle with the help of this material.
Mending a broken heart!
This has been detected that when anybody face a heart attack, he receives a heavy damage. The tissues of the affected area of the heart may die. It is also a fact that damage tissues can not be mending. However efforts are going on in this regard to use stem cells for repair of the damaged areas.
Recently the engineers of Brown University are working with scientists of India, have developed a patch made of carbon nanofibers to repair the damaged areas after heart attack. Surprisingly this patch produced by two countries scientists provides flexibility, so that it may expand and contract accordingly with the users’ heart.
When this patch is covered over the damaged tissues, the electrical signals may be transmitted through it, because it is a best conductor of electricity. It is seeded with heart cells which improved very fast on the patch, with the growth of neurons.
Quickly charged batteries
When a researcher observed that the electrically charged batteries take very much time, hence produce a problem. He solved this problem by refilling the batteries with the old charged battery fluid.
The fluid of discharged battery will be pumped out and newly charged fluid may be filled in no time. The use of these new batteries will be better in comparison to the heavy and expensive batteries. The new batteries will be lighter and cheaper, because a new liquid has been produced which is more affective than the old batteries.
