Scientists at the State University of New York’s College of Environmental Science and Forestry are developing a way to add wood fiber to plastic to make it stronger. The process extracts nanocrystals of cellulose out of woody materials such as trees and willow shrubs and mixes them with the plastic. The result is a strong, lightweight plastic that will degrade in a landfill.
“By adding an ounce of crystals to a pound of plastic, you can increase the strength of the plastic by a factor of 3,000,” says William Winter, chemistry professor and director of the college’s Cellulose Research Institute. “And in the end, in a landfill, it’s just carbon dioxide and water, which can be taken up and made into more biomass.”
Festo's BionicKangaroo combines pneumatic and electrical drive technology, plus very precise controls and condition monitoring. Like a real kangaroo, the BionicKangaroo robot harvests the kinetic energy of each takeoff and immediately uses it to power the next jump.
Design News and Digi-Key presents: Creating & Testing Your First RTOS Application Using MQX, a crash course that will look at defining a project, selecting a target processor, blocking code, defining tasks, completing code, and debugging.
These are the toys that inspired budding engineers to try out sublime designs, create miniature structures, and experiment with bizarre contraptions using sets that could be torn down and reconstructed over and over.
