61. What Are Electron Microscopes? The Transmission electron Microscope (TEM) was the first type of electron Microscope to be developed and is patterned exactly on the Light Transmission http://www.unl.edu/CMRAcfem/em.htm

Electron Microscopy What are Electron Microscopes? Electron Microscopes are scientific instruments that use a beam of highly energetic electrons to examine objects on a very fine scale. This examination can yield the following information: Topography The surface features of an object or "how it looks", its texture; direct relation between these features and materials properties (hardness, reflectivity...etc.) Morphology The shape and size of the particles making up the object; direct relation between these structures and materials properties (ductility, strength, reactivity...etc.) Composition The elements and compounds that the object is composed of and the relative amounts of them; direct relationship between composition and materials properties (melting point, reactivity, hardness...etc.) Crystallographic Information How the atoms are arranged in the object; direct relation between these arrangements and materials properties (conductivity, electrical properties, strength...etc.) Where did Electron Microscopes Come From?

64. SEM Issues Or Questions To Gary.Bauchan@ars.usda.gov The ECM Unit is equipped with state of the art scanning and transmission electron microscopes. The scanning electron microscope includes a cryostage that http://emu.arsusda.gov/

Lots of changes at ECMU including a new name, Dr. Gary Bauchan will be introducing Confocal Microscopy to the mix here in Beltsville, as well as picking up the SEM duties. And it is with much regret we say "Happy Retirement" to Eric Erbe who has moved on to new challenges after 35 years contributing science to the research community. There is no charge to collaborating management units to work with Electron Microscope Unit for short-term projects. For projects that might involve a long-term commitments or that might dominate the staff's, time then the Electron Microscope Unit will provide training and facilities for a member of the collaborator's staff. The Unit functions as a Beltsville Area facility and is funded by a service CRIS. Beltsville scientists who wish to use the Unit should discuss their prospective project with the appropriate member of the Unit's staff, Dr. Gary Bauchan :, specialist in scanning electron microscopy, Charles Murphy :, specialist in transmission electron microscopy or Christopher Pooley :, specialist in digital imaging and computer techniques.

Electron micrograph maps of Drosophila melanogaster polytene chromosomes December 1997 Anja O. Saura , Asko J. Saura and Veikko Sorsa Department of Biosciences, Division of Genetics and Department of Computer Science, University of Helsinki, Finland Contents Background References X divisions 1-10 X divisions 11-20 ... 4th chromosome divisions 101-102. See also the figures in Chromosoma 111:273-283 (2002). Chromocenter Background Polytene chromosomes (X, 2L, 2R, 3L, 3R, 4) of Drosophila melanogaster consist of 102 divisions according to the standard drawn reference maps of Bridges. Chromosome maps are needed and used when, for example, the position of a gene, the breakpoint in a chromosome rearrangement, or the location of DNA by in situ hybridization, is determined. Electron micrograph (EM) maps of the polytene salivary gland chromosomes of D. melanogaster have been published piecemeal in 1979-1996 mainly in the journal Hereditas (see the list of references Hereditas Springer-Verlag and Georg Thieme Verlag have granted permission to republish these maps on the Internet. The EM maps can be used as an additional reference to check the locations of subdivision boundaries or the names of individual bands of a chromosome region in real chromosomes instead of in a drawing.

78. A Networked Scanning Electron Microscope A laboratory designed for teaching the operation of a scanning electron microscope (SEM) has been developed at Iowa State University. http://www.tms.org/pubs/journals/JOM/9509/Chumbley-9509.html

The following article appears in the journal JOM 47 (9) (1995), pp. 13-17. JOM is a publication of Featured Overview L.S. Chumbley M. Meyer K. Fredrickson , and F.C. Laabs Introduction System Hardware System Software ... References A laboratory designed for teaching the operation of a scanning electron microscope (SEM) has been developed at Iowa State University. The laboratory was developed to enhance the education of undergraduate and graduate students in the use of the electron microscope by allowing more students to gain hands-on experience at operating an SEM. While the system was designed for teaching purposes, the concept of a multi-user SEM has clear applications for industry and research as well. For example, researchers will be able to conduct SEM investigations from their offices using desktop computers; live images can be acquired and displayed during staff meetings in a conference room; production engineers can view quality-control samples while on the production floor. In short, a multi-user SEM possesses enormous potential for a wide variety of applications. INTRODUCTION The scanning electron microscope (SEM) has become one of the most widely utilized instruments for materials characterization. Given the overwhelming importance and widespread use of the
