The 3D brick approach to self-assembly at the nanoscale is based on short synthetic strands of DNA that form building blocks, which self-assemble into 100 different, precise 3D shapes such as letters and numbers. Like the models of 80 of these shapes shown here, each unique shape measures about 25 nm per side.
Because all of this work is still in R&D it might be easy to dismiss it as blue-sky. But I discovered while doing the background research for this article that many of these projects have been underway for several years, and much of what's being done now is second- or even third-generation R&D. There's an awful lot of brains and money aimed at developing self-assembling. self-reconfiguring robots. I came away with the feeling that the future is going to be very different, indeed.
Thanks, Rob. Yes, it's already starting to look like robots are replacing cheap labor again, even in China. It's been reported that Foxconn plans to "solve" it's widely publicized labor problems by replacing humans with millions of robots:
This slideshow includes several versions of multi-materials machines, two different composites processes including one at microscale, and two vastly different metals processes. Potential game-changers down the line include three microscale processes.
UL is partnering with metals additive manufacturing (AM) supplier EOS to provide AM training to EOS's customers. It's designed to promote correct usage of AM technologies by OEMs and others in manufacturing.
To commemorate Earth Day, we take a look at the state of ocean plastic. If things don't change, by 2050 the oceans will contain more plastic than fish by weight. Here are the problems, as well as some solutions.
