Advanced electron microscopy can provide such knowledge that will enable us not only to understand, but also to control the physical and chemical behavior of nanostructured materials. The electron microscopy facility at CFN focuses on identifying nanoscale structure-property relationships of energy related materials by employing state-of-the-art instruments. We emphasize technique development that will enhance our facility capabilities for user based science as well as our own research projects.

Extractions: A imaging mode in a TEM that uses only Unscattered Electrons to form the image. Contrast in such an image is due entirely to thickness and density variations in a sample. Produced by an incident electron colliding with an atom in the specimen which is nearly normal to the incident's path. The incident electron is then scattered "backward" 180 degrees with no appreciable loss of energy, an elastic collision. The production of backscattered electrons varies directly with the specimen's atomic number. This differing production rates causes higher atomic number elements to appear brighter than lower atomic number elements. This interaction is utilized to differentiate parts of the specimen that have different average atomic number. (See Interaction Volume) An example is shown in the SEM output section, specifically the mechanically alloyed specimen micrograph. Detection of Backscattered Electrons is achieved by using a "donut" shaped solid state semiconductor device mounted on the bottom of the objective lens. When Backscattered Electrons strike the detector electron-hole pairs are created which are then counted. This quantity is translated into a pixel intensity and displayed on the CRT, forming the image. See the

I am going to add more pictures every week or when I get time for scanning in the pictures. These pictures were taken on cell lines available in my laboratory and using monoclonal antibodies developed in my lab. The herpesvirus information page will be added soon. The Flash 4 program ( virtual microscope) for fluorescence and electronmicroscopic pictures will be added (finally it start to work), which will allow to view the pictures, presented in the image gallery, at various magnifications and to move around in the picture. The web page containing various protocols will also be updated regularly. Link to this page is available from my research page.

Electron Microscopy Introduction. Electron microscopy is an imaging technique that uses an electron beam to probe a material. Since the wavelength of electrons is much smaller than the wavelength http://www.chemistry.adelaide.edu.au/external/soc-rel/content/emicrosc.htm
Extractions: Department of Chemistry Stage 2 Chemistry Social Relevance Projects. Home Contents Cross Referenced Index Experimental Procedures ... Data Analysis Electron microscopy is an imaging technique that uses an electron beam to probe a material. Since the wavelength of electrons is much smaller than the wavelength of visible light diffraction effects occur at much smaller physical dimensions. The imaging resolution in electron microscopy is therefore much better than in light microscopy The use of electron beams requires that the sample be placed in a vacuum chamber for analysis. An electron beam is produced by applying a high voltage to a hot tungsten filament, and accelerating the emitted electrons through a high electric field, 10-50 kV. The electron beam is then focussed with magnetic field lenses to a spot of 100 nm or less on the sample. A recent innovation in electron microscopy is the use of several stages of differential pumping between the electron gun and the sample, which is placed in a vacuum of a few torr. This method is called environmental electron microscopy and allows imaging of samples that would quickly vaporize in a high-vacuum environment. TEM images the electrons that pass through a sample. Since electrons interact strongly with matter, electrons are attenuated as they pass through a solid requiring the samples to be prepared in very thin sections. The image of the sample is observed on a phosphor screen below the sample, and can be recorded with film.
