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.
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.
The 100-percent solar-powered Solar Impulse plane flies on a piloted, cross-country flight this summer over the US as a prelude to the longer, round-the-world flight by its successor aircraft planned for 2015.
GE Aviation expects to chop off about 25 percent of the total 3D printing time of metallic production components for its LEAP Turbofan engine, using in-process inspection. That's pretty amazing, considering how slow additive manufacturing (AM) build times usually are.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
