according to the vienna university of technology, the researchers managed to use the cellulose extracted from the garbage waste for purification, in this way , the cellulose material obtained from the waste of old clothes and napkins to dissolve a certain class of dangerous dyes. in this method, the researchers created a coating of this nano fabric on the celluloses, which purifies the polluted water. according to the researchers, these nanostructures are launched the tiny droplets of the solution towards the target in the electric field of these droplets are converted into nanowires. with this process, 95% of dangerous dyes are removed in three cycles of clearing water contaminated with purple color. the researchers made a device that can reduce the brightness and excessive light radiation in the images. according to intersteering's scientific website, this device relies on half-air media processing with the ability to use ambient light to act as an advanced smart filter. according to american researchers, this filter helps to improve the quality of photos taken with cheap cameras slow
