I sense a bit of a recurring theme. Often mechanical designers turn to natural design to solve complicated physical problems. It seems "natural" that a chemist would turn to nature for clues to chemical problems. When considering all the lifecycle costs (including byproducts, disposal and toxicity issues) some "natural" solutions just might be better than existing "artificial solutions" in the long run.
@Dave: You are absolutely right that taking a dismissive attitude towards exploration of natural products as substitutes for industrial products is short sighted. Maybe this particular strain doesn't stand toe to toe with the industrial offering, but hopefully over time, with some research and exploration, it will.
This is an interesting development indeed. But my question is how well does it prevent corrosion in an evironment of saturated salt solution, which is more typical of the road salt contamination in this southeast corner of Michigan. Our salt is more brutal than seawater, and it is present about half of the year, until it all washes away.
My other question is about the economics of the process as compared to other methods of protection.
Chuck, at present it's a potential OEM or aftermarket anti-corrosive coating on aluminum alloys used on automotive and aerospace components. Whether it could be incorporated into other materials hasn't been determined yet.
@Ann: Thanks for the data. It looks like this coating will reduce the corrosion rate by a factor of about 3.5 at the highest concentration.
I agree with you that a dismissive attitude towards natural products is a prejudice we can ill afford. That being said, it looks like, in this case, the performance of the natural product doesn't match the performance of industrial products.
By refining topologies and using new fluid technology, Moog's new peak sine drive controller increases available power without increasing controller volume.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
