Article A A Bathroom That Cleans Itself

Science Daily (Feb. 8, 2006) — Cleaning bathrooms may become a thing of the past with new coatings that will do the job for you.

Researchers at the University of New South Wales are developing new coatings they hope will be used for self-cleaning surfaces in hospitals and the home.

Led by two Professors of the ARC Center for Functional Nanomaterials, a research team is studying tiny particles of titanium dioxide currently used on outdoor surfaces such as self-cleaning windows.

The particles work by absorbing ultraviolet light below a certain wavelength, exciting electrons and giving the particles an oxidizing quality stronger than any commercial bleach.

These nanoparticles then kill microbes and break down organic compounds. And because surfaces coated with titanium dioxide have another property called 'superhydrophilicity' -- meaning droplets do not form -- water runs straight off the surface, washing as it goes [i.e. гидрофильность].

Presently, titanium dioxide can only be activated by the UVA present in sunlight. But the UNSW team is working on ways to activate titanium dioxide with indoor light.

The team is modifying titanium dioxide nanoparticles with other elements such as iron and nitrogen so they can absorb light at longer wavelengths.

Lab trials show that glass coated with the new nanoparticles can be activated by visible light from a lamp to kill microbes.

"If you've got this on tiles or shower screens you don't need so many chemical agents," says Professor Amal.

So far the team has been working at laboratory scale. "It's probably a year before we can talk to industry and test outside the lab," says Professor Amal.

Article B Self-Cleaning Underwear Goes Weeks Without Washing

By Bill Christensen

Self-cleaning fabrics could revolutionize the sport apparel industry. The technology, created by scientists working for the U.S. Air Force, has already been used to create t-shirts and underwear that can be worn hygienically for weeks without washing.

The new technology attaches nanoparticles to clothing fibers using microwaves. Then, chemicals that can repel water, oil and bacteria are directly bound to the nanoparticles. These two elements combine to create a protective coating on the fibers of the material.

The coating both kills bacteria, and forces liquids to run off.

The U.S. military spent more than $20 million to develop the fabric, deriving from research originally intended to protect soldiers from biological weapons.

Jeff Owens, one of the scientists who worked to develop the process, said, "During Desert Storm, most casualties were from bacterial infections—not accidents or friendly fire. We treated underwear for soldiers who tested them for several weeks and found they remained hygienic. They also helped clear up some skin complaints.

Science fiction writer Neal Stephenson wrote specifically about nanotech fabrics that stayed clean; he referred to "fabricules" in his 1995 novel The Diamond Age:

.…with a quick brush, John and Gwendolyn were able to transfer most of the dirt onto their white gloves. From there it went straight into the air. Most gentlemen's and ladies' gloves nowadays were constructed of infinitesimal (мельчайший) fabricules that knew how to eject dirt... (Read more about FABRICS).
