Bearings are machine elements that reduce friction between desired moving parts. Used in any moving parts of a machine, consumer or industrial, they also help to transmit loads effectively.
Chemical engineers design large-scale processes that convert chemicals, raw materials, living cells, microorganisms and energy into useful forms and products.
The interdisciplinary field of materials science, also commonly known as materials science and engineering, involves the discovery and design of new materials, with an emphasis on solids.
