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)
I like to read articles where we as humans take God's technology and try to improve or use it in a new way. There are so many cool things that are out in nature right now and to advance or use them in a new way is very exciting.
I woudl think the auto or possibly trucking industry would be inerested if it reduces drag and increases mpg. The trucking idustry will go nuts for a lb or two reduction in vehicle weight because of the potential cost savings.
VERY interesting post Ann. Several years ago I had a consulting job involved with mounting solar collectors used in a small "solar farm". It involved the base structures and motorized mechanisms to move the collectors across the horizon as the sun traveled east to west. On HUGE factor we somewhat overlooked was keeping the collector plates clean. It's amazing how much efficiency is lost due to dirty glazers. The material you describe in your post would be very effective keeping clean surfaces. I'm going to send your post to the gentleman I worked with just to keep him informed as to what might be one possible solution to the problem.
At this point, the primary difference I see in the product descriptions is the Rustoleum product doesn't claim complete transparency; several reviews comment on the "milky sheen" it imparts to the coated surface.
Ratsky, this material isn't even commercialized yet so it's definitely not being sold at Home Depot. There have been several similar R&D announcements in the last year or so of such slippery surface/coating technology. I'd guess the Home Depot stuff is the result of one of those.
Is this the same stuff that Home Depot has been advertising recently, from Rustoleum? Too many similarities to be a coincidence. This ad just started running a few days ago. HD website has many reviews, largely mixed.
Although plastics make up only about 11% of all US municipal solid waste, many are actually more energy-dense than coal. Converting these non-recycled plastics into energy with existing technologies could reduce US coal consumption, as well as boost domestic energy reserves, says a new study.
This year's Dupont-sponsored WardsAuto survey of automotive designers and other engineers shows lightweighting dominates the discussion. But which materials will help them meet the 2025 CAFE standards are not entirely clear.
Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
SpaceX has 3D printed and successfully hot-fired a SuperDraco engine chamber made of Inconel, a high-performance superalloy, using direct metal laser sintering (DMLS). The company's first 3D-printed rocket engine part, a main oxidizer valve body for the Falcon 9 rocket, launched in January and is now qualified on all Falcon 9 flights.
