Ultra-strong Cellulose Fibers (image) Deutsches Elektronen-Synchrotron DESY Caption Artist's impression of the production of ultra-strong cellulose fibers: The cellulose nano fibrils flow through a water channel and become accelerated by the inflow of additional water jets from the sides. The acceleration lets all fibrils align with the direction of flow, finally locking together as a strong fiber.
