Stevens thermoplastic polyurethanes (TPUs) are for medical and surgical devices. These TPUs do not contain plasticizers and are suitable for high-performance products used in critical "can't fail" medical situations. Stevens Urethane Film, Sheet, and Tubing for Medical Applications brochure includes tables that compare the properties of urethane, such as elongation, tear, and strength, with other flexible materials such as PVC. Information on products using TPUs is also included.
For decades, engineers have worked to combat erosion by developing high-strength alloys, composites, and surface coatings. However, in a new paper, a team at Jilin University in China turned to one of the most deadly animals in the world for inspiration -- the yellow fat-backed scorpion.
Green energy is being billed as a way to make communities that are energy deprived more self-sustaining. So it makes sense to use natural materials to create devices that harvest this type of energy. That’s the idea behind a hybrid wind/solar energy harvester made of bamboo that’s been developed by UVM researchers.
