Scanning microscopy with electrons and x-rays.
The principle of sequential imaging, by means of a signal generated with an electron probe scanning the specimen in a regular raster, has been successfully developed into the form of practical microscopes during the past few years. The scanning electron microscope has been constructed first, but it was slow to find its proper fields of application. Now it is proving valuable primarily in solid ...
متن کاملScanning ultrafast electron microscopy.
Progress has been made in the development of four-dimensional ultrafast electron microscopy, which enables space-time imaging of structural dynamics in the condensed phase. In ultrafast electron microscopy, the electrons are accelerated, typically to 200 keV, and the microscope operates in the transmission mode. Here, we report the development of scanning ultrafast electron microscopy using a f...
متن کاملFlash Scanning Electron Microscopy
Scanning Electron Microscopy (SEM) is an invaluable tool for biologists and neuroscientists to study brain structure at the intracellular level. While able to image tissue samples with up to 5 nm isotropic resolution, image acquisition is prohibitively slow and limits the size of processed samples. In this work, we propose a novel approach to speeding up imaging when looking for specific struct...
متن کاملScanning Electron Microscopy of Dental
Dental calculus, a type of stone formed even under normal conditions, plays an important role in some periodontal diseases. Deposition of dental calculus follows plaque formation, and the variations in the degree of calcification reflect the changes in environment and form of its lamellar structure[1]. Dental plaque is composed of rods, cocci and filamentous bacteria[2], and these morphological...
متن کاملScanning Electron Microscopy of Human
I t is now generally accepted that two distinct classes of lymphocytes are present in different species including man--thymus-derived (T) cells and bone marrow or bursalderived (B) cells (1, 2). Although similar in appearance these two cell types have been demonstrated to have widely different functions. They can be distinguished electrophoretically by their different mobility (3, 4), serologic...
