Recording and Using 4D-STEM Datasets in Materials Science
Traditional scanning transmission electron microscopy (STEM) detectors are monolithic and integrate a subset of the transmitted electron beam signal scattered from each electron probe position, shown schematically in Figure 1. These convergent beam electron diffraction patterns (CBED) are extremely rich in information, containing localized information on sample structure [1], composition [2], p...
متن کاملThree Dimensional Culturing of Human Jaw Osteoblasts in PLLA/HA Scaffold
Background & Aims: Tissue engineering using somatic cells and synthetic extracellular matrix (scaffold) represents a new approach for regeneration of mineralized tissue and bone. This study was carried out to investigate the ability of a PLLA/HA scaffold to culture osteoblast cells in a three dimensional milieu. Method: Three bony samples were taken from extraction sites during surgical extract...
متن کاملUltrafast core-loss spectroscopy in four-dimensional electron microscopy
We demonstrate ultrafast core-electron energy-loss spectroscopy in four-dimensional electron microscopy as an element-specific probe of nanoscale dynamics. We apply it to the study of photoexcited graphite with femtosecond and nanosecond resolutions. The transient core-loss spectra, in combination with ab initio molecular dynamics simulations, reveal the elongation of the carbon-carbon bonds, e...
متن کاملFour-dimensional electron microscopy.
The discovery of the electron over a century ago and the realization of its dual character have given birth to one of the two most powerful imaging instruments: the electron microscope. The electron microscope's ability to resolve three-dimensional (3D) structures on the atomic scale is continuing to affect different fields, including materials science and biology. In this Review, we highlight ...
متن کاملسنتز گرافن سه بعدی و بهینه‌سازی مورفولوژی آن
Due to electrical properties (high electron mobility) and electrochemical characteristics (high electron transport rate), graphene-based materials have been widely applied for various scientific fields. However, due to their two-dimensional structures, these materials have low active sites for reaction. Therefore, changing from two-dimensional sheets dimensional to the three-dimensi...
