Janice E. . Reutt-Robey. , University of Maryland College Park, DMR 0520471. A microscope technique called “Kelvin probe microscopy” (KPM) is used to map the differences in the electrical potential on the surface of graphene on silicon carbide, shown here as different colors. KPM identifies single layer graphene (SLG), bilayer graphene (BLG), and two types of interfacial layer (IL1 and IL2). . http://biology.unm.edu/ccouncil/Biology_203/Summaries/Microscopes.htm. 1.

Compound – uses a set of lenses or lens systems (this is the type of microscope we use in class, it has the eyepiece lens (ocular) and the objective lens). October , 2017. Background Information. The microscope is one of the most commonly used instruments in the medical colleges, and in clinical laboratories. Students of physiology use it in the study of morphology of blood cells and in counting their numbers. . Always carry your scope with 2 hands (One around the handle/Arm; One supporting the base). The Handle/Arm and oculars should be facing you when using the microscope.. Only use lens paper to clean the objectives. (provided in each Student Drawer) . Depth of . f. ield: small. Magnification.
