A Bathroom That Cleans Itself 285

FiReaNGeL writes "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. It's made of a special nanoparticle coating that absorbs ultraviolet light below a certain wavelength and gives the particles an oxidizing quality stronger than any commercial bleach.

      No, if this is as powerful an oxidizer as they say, those stains won't form in the first place. The same way oxidizing cleaners break up stains, this stuff would be like having a constant coating of bleach on your bathroom surfaces. Furthermore, due to the "superhydrophilicity" of this titanium dioxide coating (as the article mentions), water will not form droplets (tension cannot be maintained), and thus you have a constant sheeting effect, allowing the surface to be very washable.

        Many of the bathrooms in the Mediterranean countries are like this. Often, they lack a well-defined shower area, have no shower curtain, sporting just a wall mounted hand-held telephone style shower head, and a central drain. (It's up to the user to make sure they don't spray the toilet paper and render it less than optimally useful!) But everything dries quite nicely, thank you. It all depends on the local humidity and temperature.
        • This is true in Finland also. There is typically a washroom in the house that has a washing machine (dryers are not often used), a sauna in a smaller subroom, and a shower area that has no door or any other seperating thing. There is often a drain in the main section of the washroom.

          There is usually another totally seperate smaller room with a toilet and sink. This caused problems for me as an exchange student -- I would wake up groggy in the morning, head into the washroom to take a shower, take of all

        Depending on where he lives, that might not be an issue. Where I live, in the arid mountain west, humidity simply isn't a problem. If something is wet, just wait a little while and it will be dry. It's fairly common for people to have high-volume humidifiers in their homes to add a little moisture to the dry air.

    How it works is that ultraviolet light below a specific wavelength causes electrons to excite and this gives the effects of oxidation. This oxidation disinfects better than commercial bleach.

    I'm not sure if I want to have that. I think "germs" and my cells aren't all that different in their ability to resist being killed. In fact, I think some germs can outlast my cells so intuitively, I don't think this idea is very safe. Maybe the right solution isn't to kill every thing but learn to live with bacterias, etc. Plus, it's not so much the micro-organisms that worry me but just rather bits of dust and hair that start to collect in some areas that bothers me and this idea doesn't really provide a solution to that.

    On the other hand, I've always wanted a titanium (not titanium oxide) clad bathroom that I can just torch or something to clean it the same way my oven does. When I first read the title, I thought someone figured out a smart and economical way of doing this.

    • This would presumably work by catalyzing the oxidation (i.e. removal of electrons from) of organic molecules at or very near the surface. In other words, it will kill cells and decolorize componds that are on the surface where there's plenty of light.

      This won't hurt your fingers for two reasons. First, the surface cells are already dead. Second, it probably won't even work when a large opaque object (your finger) is blocking the light.
      • There still are potential problems. There was recently a report that Teflon-related chemicals are turning up everywhere, including 95% of humans tested. What if this gets into the bloodstream? Imagine this stuff comes off, gets into our bloodstream, and then we go outside. Would the UV from the sun penetrate deep enough to activate this? If so, I know I wouldn't want a bunch of oxidation catalysts floating around inside me.
    • The difference is that you're a multi-celled organism, so most of your cells are shielded from harsh chemicals. For example, you could pour bleach on your foot and not suffer any serious harm. But pour even a little bleach into a beaker of suspended bacteria or yeast cells, and they will all die. I'm not sure this self-cleaning surface would be any more dangerous to a person than a surface sprayed with bleach.
    • I on the other hand, would prefer my bathroom to be coated in Iron Oxide and Aluminum. That'll teach those bastards to inhabit my dwelling, and it'll teach me the fundamentals of chemistry and fire safety. Win-win!

    As a janitor, I can tell you that this will not eliminate the need for cleaning staff. The most important thing we do is replace supplies. The next biggest thing we do is fix unusual problems before they get to be a serious problem (lady flushes sanitary product, someone shits all over sink, etc.). As far as sinks and counters go, we polish mirrors, and then get hair and soap off of sinks. The most important thing is to have the bathroom look good. This might help with getting black gunk and algae out of toilets or sanitizing fixtures, but the important things will still require janitors. People never seem to realize the amount of critical thinking required. You can't replace cleaning staff with untrained or stupid people or machines unless you want problems. We notice things that a machine wouldn't notice and clean or fix. Paying attention to small things can really save your ass sometimes. For instance, if the tone drops on the vacuum cleaner, you have a slipping belt. If you ignore it, you get melted rubber all over the floor. An untrained person doesn't notice this, and has to pay to replace burned carpet. A machine has similar problems. You can't simply automate cleanup crews.
