Multi-use Titanium Dioxide (TiO2) - Sounds Incredible Doesn't It?

Doesn't it seem that innovation comes in small waves?  You hear about this great new thought, but it comes and goes.  Then, the next new thought emerges only to pass by like the previous?  Each of those small ripples, however small, insignificant, immeasurable, only make a drastic change more likely.  

In the photo below, the contents of the test tube is definitely one of those ripples, and it seems to have potential to create much larger waves in the future.

Darren Sun, Associate Professor at Nanyang Technological University (NTU) in Singapore, has been working for years on developing "Multi-use Titanium Dioxide (TiO2)."  Without the technical jargon, this material has several important and innovative applications...

    1. "concurrently produce both hydrogen and clean water when exposed to sunlight
    2. be made into a low-cost flexible filtration membrane that is anti-fouling
    3. desalinate water as a high flux forward osmosis membrane
    4. recover energy from waste desalination brine and wastewater
    5. be made into a low-cost flexible solar cell to generate electricity
    6. doubles battery life when used as anode in lithium ion battery
    7. kill harmful microbial, leading to new antibacterial bandages"

The possibilities seem endless for this new material, far beyond the scope of clean water, but for our intent on this blog, this is yet another breakthrough in the movement to bring pure, drinkable water to the mouths of every man, woman, and child.
