Examination of Lung Parenchyma by Electron Microscopy
In this paper many of the principal structure of the Moral Lung were studied with the help of Electron Microscopy. Detailed description was given of Granular Pneumocytes, Membranous Pneumocytes, Macrophages, and Alveolar Capillaries. A discussion followed on the form and function of Granular Pneumocytes. Acknowledgements I am grateful to the Reza Shah Pahlavi Foundation for its generou...
متن کاملAtomic resolution three-dimensional electron diffraction microscopy.
We report the development of a novel form of diffraction-based 3D microscopy to overcome resolution barriers inherent in high-resolution electron microscopy and tomography. By combining coherent electron diffraction with the oversampling phasing method, we show that the 3D structure of a nanocrystal can be determined ab initio at a resolution of 1 A from 29 simulated noisy diffraction patterns....
متن کاملHigh-resolution transmission electron microscopy
High-resolution transmission electron microscopy (HRTEM) has been widely and effectively used for analyzing crystal structures and lattice imperfections in various kinds of advanced materials on an atomic scale. This is especially the case for high Tc superconductors (HTSCs). The most characteristic feature in crystal structures of HTSCs is that there is a common structural element, a CuO2 plan...
متن کاملHigh-resolution electron microscopy and electron tomography: resolution versus precision.
The performance of high-resolution electron microscopy and electron tomography is usually discussed in terms of two-point resolution, expressing the possibility of perceiving separately two image points of an object. However, the concept resolution obtains another meaning if one uses prior knowledge about the object and the imaging procedure in the form of a parametric model describing the expe...
متن کاملElectron Diffraction Using Transmission Electron Microscopy
Electron diffraction via the transmission electron microscope is a powerful method for characterizing the structure of materials, including perfect crystals and defect structures. The advantages of electron diffraction over other methods, e.g., x-ray or neutron, arise from the extremely short wavelength (≈2 pm), the strong atomic scattering, and the ability to examine tiny volumes of matter (≈1...
