Cleaning Contaminated Water Using Photocatalysts

Mila Luleva — Mon, 22 Oct 2012 14:04:47 +0000

Solar Water Disinfection is a well-known technique for cleaning contaminated water with ultraviolet rays. Although this technique has been investigated by many, Deepika Kurup still managed to find gaps that can be filled. She looked at two photocatalysts and tested whether they can accelerate the UV-decontamination power of sunlight. In particular, she studied titanium dioxide […]

Nanotube-Based Water Purifier From Stanford Filters Water Quicker, Kills Bacteria

Ovidiu Sandru — Fri, 03 Sep 2010 13:24:35 +0000

Dangerous bacteria can often hide in the water you drink, but they're not harmful until they reach a certain number to become active inside your body. Regular water purifying technologies consume a lot of power, but a team of Stanford researchers have developed a new low-cost, high-speed filter that works differently than other purifiers.
