Titanium might just be the hottest material on the planet earth right now. Out of England comes news that biochemists at Manchester Metropolitan University believe hospital superbugs could be destroyed simply by applying titanium dioxide nanoparticles to hospital surfaces, and then exposing those surfaces to fluorescent light. Titanium dioxide isn’t exactly a rare material – it’s the most commonly used white pigment. The researchers found that other paint additives, such as calcium carbonate, block the killer properties of titanium dioxide. From Toronto comes word that a company is pitching money and credit card clips made of titanium for people who don’t want to carry wallets. Why titanium? It’s lightweight, hypoallergenic, immune to salt water and extremely durable. Immune to salt water? OK, I don’t get that either. And then there’s Sarah Palin. Those titanium glasses she wears are normally slow sellers – about 9,000 a year globally. Ten days after her selection as John McCain’s running mate, the Japanese manufacturer received 12,000 orders.
