High-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 کاملHandy tool for high-resolution microscopy
738 C onventional fl uorescent microscopes normally reach their resolution limit at around 200 nm. and colleagues present a super-resolution microscopy technique capable of localizing individual fl uores-cent molecules at the 2–25-nm scale. When two or more fl uorescent proteins in a cell are less than 200 nm apart, their separate signals will be indistinguishable by the average fl uorescent mi...
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 کاملChromosome centromeres: structural and analytical investigations with high resolution scanning electron microscopy in combination with focused ion beam milling.
Whole mount mitotic metaphase chromosomes of different plants and animals were investigated with high resolution field emission scanning electron microscopy (FESEM) to study the ultrastructural organization of centromeres, including metacentric, acrocentric, telocentric, and holocentric chromosome variants. It could be shown that, in general, primary constrictions have distinctive ultrastructur...
متن کاملHigh resolution electron spin resonance microscopy.
NMR microscopy is routinely employed in fields of science such as biology, botany, and materials science to observe magnetic parameters and transport phenomena in small scale structures. Despite extensive efforts, the resolution of this method is limited (>10 microm for short acquisition times), and thus cannot answer many key questions in these fields. We show, through theoretical prediction a...
