Web2. Pause in the presentations as appropriate to demonstrate use of the microscope on the podium. a. (Slides 2,3) Materials science and technology relates to the relationships between structure, properties and processing of materials. Typical examination of metals relates to the observation of the microscopic structure, called "microstructure." WebLamellae can also describe the layers of atoms in the crystal lattices of materials such as metals. In surface anatomy, a lamella is a thin plate-like structure, often one amongst many lamellae very close to one another, with open space between. In chemical engineering, the term is used for devices such as filters and heat exchangers.
