"Perhaps in the future our laundry does not use water and detergent. Just they will have some UV lamps and clothes will "wash" only with light, "says Bozidar Stefanov. He is 21-year-old student in Computational Chemistry at Sofia University "St. Kliment Ohridski ", working in the Laboratory of Nanotechnology of the University and was a finalist in the competition for Bulgaria FameLab (lab fame), city hunter ost download organized by the British Council. In the contest of young scientists tried in an understandable way to communicate to the general public new scientific discoveries that will change our lives.
Bozhidar Stefanov clothes of the future will clean themselves - without chemicals, detergent or water. It would be enough to fall flat soiled clothes in the sun or some time to UV light. As a result, they will light up on purity. By simple chemical reaction (described below), only under the influence of light, all the bacteria and stains disappear. In this process will be given only of carbon dioxide and some water.
The fibers of the self-cleaning clothes to wear at times slower than now, and the colors will not fade for years. Scientific development is so advanced that 2 years ago in the United States and Italy launched the first such clothes for sale to the public - mostly self-cleaning and linen shirts.
Like many of the innovations city hunter ost download in bits, self cleaning clothes are fictitious First Army. In the United States found that more than their soldiers (in the contingent world and in military units) hospitalized because of poor hygiene, not from injuries sustained during the war. So did the American city hunter ost download army lingerie that cleans city hunter ost download by itself through sunlight.
More on fabric for garment, textile fibers are first stained to the desired color (not self-cleaning of the dyes and then fade). city hunter ost download Then coated with a film of titanium dioxide. This is a natural material which exist in nature and is extracted from it, but can also be obtained by artificial means. Titanium dioxide is the most non-toxic white solid. city hunter ost download There's all white paints. He easily takes the form of small particles. Has the ability to absorb sunlight in which undergoes a chemical reaction with oxygen and turns it into radicals.
By covering the textile fiber titanium dioxide, they are protected city hunter ost download from the UV light of the sun and the garment does not fade. Moreover, the coating maintain the fibers and they are more difficult to wear. An interesting feature of the titanium film is that it does not repel stains. On the contrary - connects with them and seal the fabric. When we dress and put it in the sun, ultraviolet light from sunlight activates the titanium dioxide. It reacts with oxygen from the air and turns it into radicals. Radicals are molecules that have one electron city hunter ost download more (or one less) and will do everything possible to give their excess city hunter ost download electron to another city hunter ost download molecule or to take another one from another molecule.
These radicals go to spots that are the only thing on the garment, which could react and begin to oxidize. Lastly, the stain remains only carbon dioxide and water. Through chemical reactions described titanium dioxide and kill bacteria. That is, stretch and dry contaminated city hunter ost download clothing in the sun, and after a few hours picking them clean and slightly damp.
"Right now, it gets a little slow, says Bozidar Stefanov. I watched experiment American scientist who managed to remove the stain of red wine and puts the garment 20 hours of sunlight, but in the future the process will accelerate. The good thing is that it does not require water or detergent. No bleach, bleaching agents, phosphates and other harmful substances. Only the sun. "

Look this: http://www.vbox7.com/play:7bcaee8c 4) D-r July 1, 2009 at 12:28 pm stains on clothes city hunter ost download can be cleared, but assholes are still assholes. 5) Moderate July 1, 2009 at 2:20 pm Good for this guy! I hope these young people to stay in Bulgaria! I do not understand debilnite comment section below, city hunter ost download but the country is this: everything omaskarayava and odebilyava. Dec. fuck him, come to care. Talk about important scientific advances of great ecological city hunter ost download importance and comments in the direction of the moon. That's why we have civil society and nothing has ordered ... 6) Anonymous July 1, 2009 at 2:40 pm What's civil society? After 65 years of communist rule! 7) Chicha July 1, 2009 at 3:01 pm sandals in front of me, believe that in order to have them clean clothes, first, you have to build a civil society / nice people, civil does not mean urban as you are with Bulgarian
