Naturally, the contaminated water is able to be sterilized by sunlight through the UV rays that kill bacteria within 48 hours to complete the process. However, a tiny gadget being developed by the researchers from Stanford University and SLAC National Accelerator Laboratory utilizes a wider spectrum of sunlight to speed up the sterilization process.

"Our device looks like a little rectangular black glass," explains lead researcher Chong Liu of Stanford University. "We just dropped it into the water and put everything under the Sun, and the Sun did all the work."
The Sun's rays are moving electrons in the device using a molybdenum disulfide that is capable of creating a reaction in the water. Hydrogen peroxide and other disinfectants evolving from this reaction, which is able to work to clean the bacteria in the water.
"It really works. Our concern is to find ways to overcome the problem of pollution so that people can live better," said Liu. This technology is able to compete in the market, because molybdenum disulfide is very cheap to produce. Thus the process of sterilizing water with this tool will be more efficient and cheaper.
Although promising, but this method does not eliminate chemical pollutants researcher and has only been tested on three strains of bacteria were mixed with less than one ounce of water in a laboratory. The next step is to test the device in real-world stew contaminants. *** [EKA | FROM VARIOUS SOURCES | SCOPE]
