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.

Fruit Juice fights corrosion?

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.

Beth, yes, that's what I had in mind. I have no evidence there's a parallel here, but am merely wondering, since dates are a food crop.

Uhhh, Beth, sugars deteriorate teeth because they provide a hospitiable growth environment for bacteria which cause the damage.

Seen any aluminum-eating bacteria lately?

Perhaps parallel to the corn harvest/ethanol scenario from a while back?

If I understand your statement, the date palm juice is 1/3 as good as an industrial chromate?  That's not a negative statement but simple comparison.

The lower corrosion resistance is possibly more than offset by the ease of handling of the waste.

@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.

Ann, any idea how this knowledge might be employed in future materials?

The Dutch are known for their love of bicycling, and they’ve also long been early adopters of green-energy and smart-city technologies. So it seems fitting that a town in which painter Vincent van Gogh once lived has given him a very Dutch-like tribute -- a bike path lit by a special smart paint in the style of the artist's “Starry Night” painting.
