Created reusable paper on which you can print with light

Paper manufacture tens of tons of wood are used annually, which hectares of "lung of the planet". Therefore, reducing the amount of wood use is essential for our existence. Recycling is only partially solves the issue. But a group of scientists from Shandong University (China), University of California at Riverside and the National Laboratory Lawrence (USA) has developed a new type of reusable paper on which you can write with the help of light waves.

In this paper, "a new type of" special use nanoparticles that can change color under the influence of the ultraviolet part of the light spectrum. Finest coating containing these nanoparticles can be coated on the surface of virtually any material. When this erase process such "paper" occurs during the heating to a temperature of 120 degrees Celsius. As the author of the invention claimed, UCLA professor Yadong Ying,

"We have developed a new class of photographic material, reversibly changes its color when exposed to light. And as a demonstration of the possibilities of this material, we have created samples of rewritable paper that can be used many times and for printing that requires no ink or toner. This invention has many advantages for economic and environmental plan, it will allow us to eliminate the need for disposal and recycling of millions of tons of waste paper. "

The new reusable paper is a great solution in case if the information on it is relevant in a short period, for example, in draft or newspapers and magazines. It can be used to write by hand, using a special light pen, and in the light of special printers designed specifically for this type of paper.

"We believe that the rewritable paper can be successfully used for the production of newspapers, magazines, posters and other printed materials, information on which has a low relevance of the term. In addition to paper, our technology can be used in many other areas, for example, in a variety of sensors, stickers with a shelf life of products and so on. "
