Television touch screen has been marketed long ago, now the people are demanding for mobiles touch screen. It is said that touch screen should be highly sensitive, transparent and has good conductivity. For the purpose researchers are using an element called indium, but on the other hand facing a problem that indium is found very rare on earth.After a lot of experiments a substitute has been discovered called Carbon nanotubes, which is different from Carbon fibers. The Carbon nanotube is fifty thousand times thinner than a human hair, but found extraordinary stronger and could be stressed up to 18 centimeter. Carbon nanotubes may be used in many fields, such as optics material, science and electronics.
Computer control cars convey
The careless drivers always cause accidents due to the fast speed or carelessness. It produces a lot of problems to the citizens. Hence to overcome this serious factor the scientists make a program to control the cars convey from computer. Sensitive cameras and sensors will be fitted in the cars to connect them together without any wire or mechanism.
In this way the drivers of the cars could sleep or read a thick novel of Robert Ludlum on the driving seat, keeping their cars on a suitable distance. Hence by this controlling the cars will not face any accident and everybody will reach up to his destination safely. To facilitate other drivers, it is manage that anyone could come in convey at any moment and may depart himself at any time. This computer control cars convey is tested successfully by the Volvo in Sweden and the project is funded by the European commission, with an amount of six million Euros.
Food freshening plastic
Even the food which kept in the refrigerators decay after a particular period, but a professor in Sweden introduce a plastic sheet, when wrapped around the food, it protect the food from decaying. The plastic indicates you the decaying by changing its color. But researcher in Germany has improved it by producing a new kind of plastic sheet, when rapped around the food will keep it fresh for a long time.
The plastic sheet is treated by a layer of chemicals, when wrapped around the food it comes in contact with the food and starts releasing the antibiotics which defend against the bacteria. It saves the food like meat, fish and cheese for a long time.
Unbreakable glass
Astonishing news came from California that a glass has been produced which is unbreakable and stronger than steel. This glass may bend, but cannot break. The Unbreakable property of glass has been produced by an element Palladium. After testing, it is proved that the substances which have been produced in the past to avoid breaking, cannot match with this glass. Due to this fantastic quality this glass will be used for industrial products, as well as for defense.
