High-purity titanium has been subjected to dynamic compression with a strain rate of 103 s−1 activate {112-2} and {112-4} contraction twins. Electron backscatter diffraction (EBSD), transmission electron microscopy (TEM), high-resolution TEM (HRTEM) were performed observe the morphologies twin boundaries The results show that twins are predominant twinning mode, as well formation due change in ...

Recent years have witnessed the rise of an emerging class synthetic two-dimensional (2D) materials-2D polymers. The combination organic chemistry and rational design polymeric crystals has stimulated tremendous research efforts in controlled synthesis 2D However, despite advancement methodologies, structural characterization polymers remains a significant challenge. Although aberration-correcte...

ZnO nano-particles is synthesized using hydrated zinc chloride (ZnCl2.2H2O) as main raw components. It calcined at different temperatures (i.e., 200 ⁰C, 400 ºC, 600 ⁰C and 800 ⁰C). Synthesized characterized by XRD, SEM/EDS, HRTEM, UV Visible, Band Gap. XRD result showed pure wurtzite-structure crystalline nature. Both results SAED obtained from pattern HRTEM studies are indicated similar inform...

In order to achieve this goal, the respective samples should be both simultaneously: eminently thin and free-standing. With respect to this technological challenge, world wide only few successful experiments are known. In case of semiconductor nanofoils so far no experiments are known. In case of graphene there is one, but very elaborate measuring principle. On this, a sheet of graphene is moun...

The S-state model describes the dynamical scattering of electrons in a specimen foil, consisting of atom columns parallel to the beam direction, such as a crystal or a particular crystal defect. In this model the electrons are considered to be trapped in the electrostatic potential of an atom column, in which it scatters dynamically. This picture allows physical insight, and it explains why a o...

Defect structures in CuZr martensite are studied by conventional and high-resolution transmission electron microscopy. Two different types of planar defects are observed. It is concluded that both defect types can be inherited from anti-phase boundaries in the austenite phase. With respect to the martensitic transformation, both defect types can be explained by the different shuffles of atoms a...
