Developers at Laser Zentrum Hanover (LZH, Germany) are using their two-photon polymerization system to create 100-200 nm structures. The idea is similar to rapid prototyping, but in 3D rather than building with 2D layers. Twin laser beams, generating femtosecond laser pulses focused at the same point in a liquid resin, sweeping through three dimensions, form the nanostructures or microstructures. Two-photon polymerization solidifies the resin at the localized focus area.
A simple new chemical method for repairing and recycling notoriously difficult carbon fiber composites has been developed by the Fraunhofer Institute for Applied Polymer Research. An entire component can be completely recycled, including reclaiming its expensive carbon fibers for reuse.
In today’s connected world we are seeing the beginning of connected homes, smart grids, self-driving automobiles, drones, and many other amazing devices. Out of all the soon-to-be connected devices, which device poses the greatest dangerous to its users and society?
