"The mechanical properties of natural joints are considered unrivalled. Cartilage is coated with a special polymer layer allowing joints to move virtually friction-free, even under high pressure. Using simulations on Jülich's supercomputers, scientists from Forschungszentrum Jülich and the University of Twente have developed a new process that technologically imitates biological lubrication and even improves it using two different types of polymers."
