Review Paper: Embryonic Stem Cell and Osteogenic Differentiation
Bone tissue engineering has been one of the most promising areas of research, providing a potential clinical application to cure bone defects. Recently, various stem cells, including embryonic stem cells (ESCs), bone marrow-derived mesenchymal stem cells (BM-MSCs), umbilical cord blood-derived mesenchymal stem cells (UCB-MSCs), adipose tissue-derived stem cells (ADSCs), muscle-derived stem cell...

متن کاملMonochromator for Aberration-Corrected STEM
In a scanning transmission electron microscope (STEM), the elemental analysis at atomic resolution is realized by the combination with electron energy-loss spectroscopy (EELS), since an aberration corrected probe forming lens system enables us to obtain an electron probe sized about 0.1 nm [1]. In EELS, the energy resolution is mainly limited by the energy spread of the electron source, which i...
متن کاملHitachi’s Spherical Aberration Corrected STEM: HD-2700
INTRODUCTION AS VLSI (very large scale integration) technology evolves toward ever smaller features and multilayer designs, analysis and control of structures and compositions at the atomic level is becoming increasingly important. In 1998 Hitachi HighTechnologies Corporation released the HD-2000, a STEM (scanning transmission electron microscope) that was very well received for combining the e...
متن کاملAberration corrected STEM of iron rhodium nanoislands
Iron-rhodium (FeRh) nanoislands of equiatomic composition have been analysed using scanning transmission electron microscopy (STEM) electron energy loss spectroscopy(EELS) and high angle annular dark field (HAADF) techniques. Previous magnetometry results have lead to a hypothesis that at room temperature the core of the islands are antiferromagnetic while the shell has a small ferromagnetic si...
