Advanced electron microscopy can provide the fundamental knowledge that will enables us not only to understand, but also to control the physical and chemical behavior of nanostructured materials. The electron microscopy facility at the 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 research projects that we lead to further the DOE’s energy mission.

Electron microscope From Wikipedia, the free encyclopedia   (Redirected from Electron microscopy Jump to: navigation search Diagram of a transmission electron microscope A 1973 Siemens electron microscope, Musée des Arts et Métiers Paris An electron microscope is a type of microscope that produces an electronically-magnified image of a specimen for detailed observation. The electron microscope (EM) uses a particle beam of electrons to illuminate the specimen and create a magnified image of it. The microscope has a greater resolving power than a light-powered optical microscope , because it uses electrons that have wavelengths about 100,000 times shorter than visible light ( photons ), and can achieve magnifications of up to 2,000,000x, whereas light microscopes are limited to 2000x magnification. The electron microscope uses electrostatic and electromagnetic "lenses" to control the electron beam and focus it to form an image. These lenses are analogous to, but different from the glass lenses of an optical microscope that form a magnified image by focusing light on or through the specimen. Electron microscopes are used to observe a wide range of biological and inorganic specimens including microorganisms cells , large molecules biopsy samples

Transmission electron microscopy From Wikipedia, the free encyclopedia Jump to: navigation search A TEM image of the polio virus. The polio virus is 30 nm in size. Transmission electron microscopy TEM ) is a microscopy technique whereby a beam of electrons is transmitted through an ultra thin specimen, interacting with the specimen as it passes through. An image is formed from the interaction of the electrons transmitted through the specimen; the image is magnified and focused onto an imaging device, such as a fluorescent screen, on a layer of photographic film , or to be detected by a sensor such as a CCD camera TEMs are capable of imaging at a significantly higher resolution than light microscopes, owing to the small de Broglie wavelength of electrons. This enables the instrument's user to examine fine detail—even as small as a single column of atoms, which is tens of thousands times smaller than the smallest resolvable object in a light microscope. TEM forms a major analysis method in a range of scientific fields, in both physical and biological sciences. TEMs find application in cancer research, virology, materials science as well as pollution and semiconductor research. At smaller magnifications TEM image contrast is due to absorption of electrons in the material, due to the thickness and composition of the material. At higher magnifications complex wave interactions modulate the intensity of the image, requiring expert analysis of observed images. Alternate modes of use allow for the TEM to observe modulations in chemical identity, crystal orientation, electronic structure and sample induced electron phase shift as well as the regular absorption based imaging.

Home Faculty Adviser Daniela Nicastro Rosenstiel 449 nicastro@brandeis.edu MRSEC Facilities Electron Microscopy Electron Microscopy Brandeis We are establishing a new facility for correlative light and electron microscopy that will allow us to study structural details of materials at scales, ranging from nanometers to many microns. The basic idea is to bring together light and electron microscopy techniques in a facility that will be unique in the nation. The correlative approach will provide a new window into the functional organization of cells and other materials. We have been able to win a major NSF-MRI grant ($930,000) to support the initiative and to buy equipment, such as light microscopes and sample preparation gear. The new instrumentation includes a high pressure freezer with rapid specimen transfer unit, a freeze substitution device, a cryoultramicrotome and two different confocal light microscopes. The lab space will be reconfigured to accommodate the space and climate-control requirements of the instruments.

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?

ELECTRON MICROSCOPY I. Limits to Resolution A. AbbeFourier Optics apply diffraction theory to coherent imaging. The lens focuses the diffracted rays from the object to form the Fraunhofer diffraction pattern of the object at the back focal plane of the lens (Fig. 1a); this is a spatial frequency analysis of the object, i.e. a Fourier Transform. The image is formed by a 2nd Fourier transformation and is a magnified inverted image of the object. The magnification is R /R o , the ratio of the lens-image distance the lens-object distance. The image is not a "true" representation of the object because: lens aberrations alter the Fourier Transform the lens aperture (expressed by its half angle, a ) may limit how many diffraction orders pass ===> resolution is limited Fig. 1 a b Quantitation : If 2 image points are separated by a distance, d, then their first diffraction order will occur at an angle, q which will permit the path difference for light waves diffracted from the two points to constructively interfere; this means that the path difference, d , for the two waves must equal the wavelength, l , of the radiation or d = d n sin( q l where n is the index of refraction of the medium (Fig. 1b). The resolution limit is (approximately) equal to the d which corresponds to a first order diffraction at
