Monday morning, and the news is smashing! Revolutionary titanium dioxide nanofiber membranes, biomimetic chemical reduction with a transition metal catalyst, and making capillary tube tips 11 nanometers wide using a scanning electron microscope. Is this a great time to be alive, or what!
Prof Sun's multi-use titanium dioxide can:
concurrently produce both hydrogen and clean water when exposed to sunlight
be made into a low-cost flexible filtration membrane that is anti-fouling
desalinate water as a high flux forward osmosis membrane
recover energy from waste desalination brine and wastewater
be made into a low-cost flexible solar cell to generate electricity
doubles battery life when used as anode in lithium ion battery
kill harmful microbial, leading to new antibacterial bandages
These days the good news always seems to come from technology and research, while economics, politics, and ecology generate bad news.
Wow - thanks so much for the technology news. It is exciting to see the advances.
