Resumen

The High Voltage Electron Microscopy Laboratory [HVEM] at the University of Wisconsin-Madison, a National Institutes of Health Biomedical Research Technology Resource, has recently been renamed the Integrated Microscopy Resource for Biomedical Research [IMR]. This change is designed to highlight both our increasing abilities to provide sophisticated microscopes for biomedical investigators, and the expansion of our mission beyond furnishing access to a million-volt transmission electron microscope. This abstract will describe the current status of the IMR, some preliminary results, our upcomin

Resumen

Diagnostic electron microscopy is a useful technique for the identification of viruses associated with human, animal, or plant diseases. The size of virus structures requires a high optical resolution (i.e., about 1 nm), which, for a long time, was only provided by transmission electron microscopes operated at 60 kV and above. During the last decade, low-voltage electron microscopy has been improved and potentially provides an alternative to the use of high-voltage electron microscopy for diagnostic electron microscopy of viruses. Therefore, we have compared the imaging capabilities of three l

Resumen

One class of biological structures that has always presented special difficulties to scientists interested in quantitative analysis is comprised of extended structures that possess fine structural features. Examples of these structures include neuronal spiny dendrites and organelles such as the Golgi apparatus and endoplasmic reticulum. Such structures may extend 10's or even 100's of microns, a size range best visualized with the light microscope, yet possess fine structural detail on the order of nanometers that require the electron microscope to resolve.

Resumen

For surface science, the 1980s were the decade in which the microscopes arrived. The scanning tunneling microscope (STM) was invented in 1982. Ultrahigh vacuum transmission electron microscopy (UHVTEM) played a key role in resolving the structure of the elusive Si(111)-7 × 7 surface. Scanning electron microscopy (SEM) as well as reflection electron microscopy (REM) were applied to the study of growth and islanding. And low-energy electron microscopy (LEEM), invented some 20 years earlier, made its appearance with the work of Telieps and Bauer.LEEM and TEM have many things in common. Unlike STM

Resumen

The Photoelectron Emission Microscope (PEEM) and Low Energy Electron Microscope (LEEM) are parallel-imaging electron microscopes with highly surface-sensitive image contrast mechanisms. In PEEM, the electron yield at the illumination wavelength determines image contrast, in LEEM, the intensity of low energy (< 100 eV) electrons back-diffracted from the surface, as well as interference effects, are responsible for image contrast. Mirror Electron Microscopy is also possible with the LEEM apparatus. In MEM, no electron penetration into the solid occurs, and an image of surface electronic poten

Resumen

The steady evolution of computer controlled electron microscopes is dramatically changing the way we teach microscopy. For today’s microscopy student, an electron microscope may be just another program on the desktop of whatever computer platform he or she uses. This is reflected in the use of the term Desktop Microscopy. The SEM in particular has become a mouse and keyboard controlled machine, and running the microscope is not very different from using a drawing program or a word processor. Transmission electron microscopes are headed in the same direction.While one can debate whether or not

Resumen

Light microscopic imaging has experienced a renaissance in the past decade or so, as new techniques for high resolution 3D light microscopy have become readily available. Light microscopic (LM) analysis of cellular details is desirable in many cases because of the flexibility of staining protocols, the ease of specimen preparation and the relatively large sample size that can be obtained compared to electron microscopic (EM) analysis. Despite these advantages, many light microscopic investigations require additional analysis at the electron microscopic level to resolve fine structural features

Scanning electron microscopes offer several unique advantages and they have evolved into complex integrated instruments that often incorporate several important accessories. Their principle advantage stems from the method of constructing an image from a highly focused electron beam that scans across the surface of a specimen.

In recent years the development of remote microscopy, specifically in electron microscopes, has begun to emerge as a useful research tool rather than simply an educational or teaching aid. Scientists have long been able to work collaboratively at a distance; however, it is often in terms of receiving data or sending some instructions where there may be a delay in receipt of the information. When defining remote control it is important to note that electron microscopy requires instantaneous control and receipt of the feedback (in most cases via images on a screen).

An ever-present limitation of transmission electron microscopy is the damage caused by high-energy electrons interacting with any sample.

Measuring the time to achieve an electron count threshold rather than waiting a predefined constant time improves the information obtained per electron.

Resumen

Microscopy has always been concerned with the observation of samples in their natural states. The earliest instruments, optical microscopes, did not interfere with the samples which were under observation due to the pervasive presence of visible light in the normal evolution of these entities. Man and science persisted in this direction until Ruska in 1933 invented the electron microscope and the real world changed forever (see MSA Rudenberg for an enlightening description of the early days of man's understanding of the electron and the subsequent invention of the electron microscope).

Resumen

EIGER is a single-photon-counting hybrid pixel detector developed at the Paul Scherrer Institut, Switzerland. It is designed for applications at synchrotron light sources with photon energies above 5 keV. Features of EIGER include a small pixel size (75 µm × 75 µm), a high frame rate (up to 23 kHz), a small dead-time between frames (down to 3 µs) and a dynamic range up to 32-bit. In this article, the use of EIGER as a detector for electrons in low-energy electron microscopy (LEEM) and photoemission electron microscopy (PEEM) is reported. It is demonstrated that, with only a minimal modificatio

Resumen

The strong interaction of electrons with small volumes of matter make them an ideal probe for nanomaterials, but our ability to fully use this signal in electron microscopes remains limited by lens aberrations. To bring this unique advantage to bear on materials research requires a sample space for electron scattering experiments in a tunable electron-optical environment. This is the vision for the Transmission Electron Aberration-corrected Microscope (TEAM) project, which was initiated as a collaborative effort to re-design the electron microscope around aberration-correcting optics.

Resumen

Characteristics of electron microscope film emulsions, such as the speed, the modulation transfer function, and the exposure dependence of the noise power spectrum, have been studied for electron energies (80-100keV) used in conventional transmission microscopy. However, limited information is available for electron energies in the intermediate to high voltage range, 300-1000keV. Furthermore, emulsion characteristics, such as optical density versus exposure, for new or improved emulsions are usually only quoted by film manufacturers for 80keV electrons. The need for further film emulsion studi

Resumen

The observation of nano materials or nano phases is generally performed using Transmission Electron Microscopy (TEM) because conventional Scanning Electron Microscopes (SEM) do not have the resolution to image such small phases. Since the last decade, a new generation of microscopes is available on the market. These are the Field Emission Scanning Electron Microscope (FE-SEM) with a virtual secondary electron detector. The FE-SEM have a higher brightness allowing probe diameter smaller than 2.5 nm with incident electron energy, E0, below 5 keV. Furthermore, what gives FE-SEM outstanding resolu

Resumen

Background purpose: The revolution in microscopy came in 1930 with the invention of electron microscope. Since then, we can study specimens on ultrastructural and even atomic level. Besides transmission electron microscopy (TEM), for which specimen preparation techniques will be described in this article, there are also other types of electron microscopes that are not discussed in this review. Materials and methods: Here, we have described basic procedures for TEM sample preparation, which include tissue sample preparation, chemical fixation of tissue with fixatives, cryo-fixation performed by

Resumen

The quantitative interpretation of scanning Auger electron microscope (SAM) images has been shown to require the use of multi-spectral imaging of the surface under study. In a multi-spectral analytical microscope (MULSAM) a set of maps (bands) is acquired from the same area of a sample using scattered electrons with different kinetic energies as well as other signals from the sample such as current flowing to ground, the conventional SEM signal and characteristic x-rays. The resulting set of bands is a multi-spectral image which can be processed using models of the electron scattering in the s

Resumen

Labeling textile blends requires identification and quantification of their fibrous components. Blends of specialty animal fibers with sheep's wool are of special, practical importance; for these the light microscope is the traditional tool of analysis. To investigate the actual applicability of light microscopy for analyzing such blends as an alternative to the scanning electron microscope (SEM), we analyzed in detail the results of round trials conducted in the seventies. The results confirm that light microscopy, in general, is neither an objective nor a reproducible method for analyzing wo
