The diffractive imaging process used for retrieval of an aberration-free exit-wave function of a complex-valued object is optimized with a newly developed automated chaining diffraction (ACD) algorithm. Our algorithm enables automatic recovery of the amplitude and phase of the complex-valued objects with diffraction-limited resolution, starting from selected-area electron diffraction (SAED) pat...

Electron microscopy techniques yield information for crystal structure analysis that is remarkably complementary to that obtained from X-ray powder diffraction data. Structures of polycrystalline materials that resist solution by either method alone can sometimes be solved by combining the two. For example, the intensities extracted from an X-ray powder diffraction pattern are kinematical and c...

The ordered tin disulfide (SnS(2)) nanowire arrays were first fabricated by sulfurizing the Sn nanowires, which are embedded in the nanochannels of anodic aluminum oxide (AAO) template. SnS(2) nanowire arrays are highly ordered and highly dense. X-ray diffraction (XRD) and corresponding selected area electron diffraction (SAED) patterns demonstrate the SnS(2) nanowire is hexagonal polycrystalli...

Pure and doped ZnS nanocrystalline phosphors were prepared at room temperature using a chemical synthesis method. Transmission electron microscopy observation shows that the size of the ZnS crystals is in the 2-3 nm range and SAED pattern confirms the cubic and crystalline nature of the observed samples, which are in agreement with X-Ray analysis. Interesting luminescence characteristics such a...

Transition metal fluoride/carbon nanocomposites have been under extensive investigation in the past ten years due to their theoretical high capacity in the range of 500 to 800 mAh/g [1]. In this study, the structural changes of FeOF/C positive electrode during lithiation/delithiation have been studied as a function of number of cycles (up to 20) under constant cycling current of 50 mA/g and at ...

LDH nanosheets were obtained via continuous impaction and exfoliation by herring sperm DNA molecules using a constant vibration method. DNA-LDH nanohybrids were composed by electrostatic forces and they exhibited DNA-enhanced peroxidase-like activity. The morphology and structure of DNA-LDH nanohybrids were analyzed by transmission electron microscopy (TEM), selected-area electron diffraction (...
