Super-Slippery Coating Inspired by Carnivorous Plant
An ultraslippery coating that repels oil and water even on vertical surfaces is created with a glass honeycomb-like structure with craters (left). This is coated with a Teflon-like chemical (purple) that binds to the honeycomb cells to form a stable liquid film. The film repels droplets of both water and oily liquids (right). Because it's a liquid, it flows, which helps the coating repair itself when damaged. (Source: Nicolas Vogel, Wyss Institute)
This is quite an interesting development, Ann, and the way scientists used their inspiration to create such a unique and useful material is fascinating. I wouldn't have even known about this plant, yet alone thought to use it to inspire a self-healing, durable material like this that could have a major impact on future product and device design. I am endlessly suprised by where researchers glean their creative inspiration for some of the inventions we cover.
Alcoa has unveiled a new manufacturing and materials technology for making aluminum sheet, aimed especially at automotive, industrial, and packaging applications. If all its claims are true, this is a major breakthrough, and may convince more automotive engineers to use aluminum.
NASA has just installed a giant robot to help in its research on composite aerospace materials, like those used for the Orion spacecraft. The agency wants to shave the time it takes to get composites through design, test, and manufacturing stages.
The European Space Agency (ESA) is working with architects Foster + Partners to test the possibility of using lunar regolith, or moon rocks, and 3D printing to make structures for use on the moon. A new video shows some cool animations of a hypothetical lunar mission that carries out this vision.
If there's one thing 3D printing's good for, it's customization. New Balance Athletic Shoe Company has begun using 3D printing to make customized spike plates for its running shoes made for members of its Team New Balance runners. They provide better traction and shave off a tiny bit of weight.
Two teams, one based in the US and one in Europe, have 3D printed space-worthy support structures for satellite antenna arrays. These aren't prototypes: they're fully functioning antenna supports that will operate while exposed to the harsh temperatures and radiation of outer space.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
