Tribology is the science and technology of friction, wear, and lubrication. Atomic Force Microscopy (AFM) is an important tool for understanding nanoscale tribological phenomena. In this webinar, Asylum Research applications scientist Ted Limpoco will first introduce how AFMs can be used to measure friction at the nanoscale and show how this is used to study tribofilms, contacts in MEMs devices, and in developing bioinspired lubrication.
Dr. Shivaprakash Ramakrishna, senior scientist at ETH Zurich, will then present his research on the nanotribology of linear and cyclic polymer brushes on surfaces. These polymer “brushes” consist of macromolecules chain end-grafted to a solid surface. They have attracted the attention of researchers in applications ranging from the generation of boundary lubricants to the fabrication of biopassive interfaces in medical devices.
