Brief Introduction to Freeze Fracture and Etching
Freeze fracture describes the technique of breaking a frozen specimen to reveal internal structures. Freeze etching is the sublimation of surface ice under vacuum to reveal details of the fractured…Read article
Analysis of Oil Shale as an Alternative Source of Energy
For some years now, the search for alternative sources of raw materials has concentrated on oil shale deposits. As the exploitation of these raw materials is still extremely complex and expensive,…Read article
Brief Introduction to Coating Technology for Electron Microscopy
Coating of samples is required in the field of electron microscopy to enable or improve the imaging of samples. Creating a conductive layer of metal on the sample inhibits charging, reduces thermal…Read article

Brief Introduction to Critical Point Drying
One of the uses of the Scanning Electron Microscope (SEM) is in the study of surface morphology in biological applications which requires the preservation of the surface details of a specimen. Samples…Read article
Focussed Ion Beam Milling and Scanning Electron Microscopy of Brain Tissue
This protocol describes how biological samples, like brain tissue, can be imaged in three dimensions using the focussed ion beam/scanning electron microscope (FIB/SEM). The samples are fixed with…Read article
