Three-Dimensional Morphology of Polymer Nanocomposites Characterized by Transmission Electron Tomography
… increment and reconstruction algorithms are three of the main factors affecting the quality of tomograms. An anisotropic degradation can be observed with restricted tilting range and increment. Therefore, this study was carried out to investigate the accuracy of the reconstruction results of …

Microbial Communities of Healthy and Diseased Corals
… extent of phenotypic plasticity in the corallite morphology of colonies of M. annularis s.s. was determined by analyzing the three-dimensional morphology of calical surfaces and the two-dimensional corallite morphology as represented in transverse thin sections. Significant phenotypic plasticity …

Automatic 3D Neuron Tracing from Optical Microscopy Images.
Neuron tracing is the process of reconstructing three-dimensional morphology of neurons from microscopy images. It is essential for delivering more comprehensive understanding of the relationship between neuronal structure and function, which is the fundamental to know how the brain works. However, …

Electron microscopy characterisation of size-selected Pd clusters and industrial Pd catalysts
This thesis presents an investigation into the morphology of palladium (Pd) size selected clusters and industrial Pd catalysts using high angle annular dark field scanning transmission electron microscopy (HAADF-STEM) technique. The driving force of this work is to establish reliable and efficient …

High-Resolution Imaging of Dense Gas Structure and Kinematics in Nearby Molecular Clouds with the CARMA Large Area Star Formation Survey
… to quantify the hierarchical nature and three-dimensional morphology of cloud structure. I first describe the CARMA Large Area Star Formation Survey, which provides spectrally imaged \NtwoH{}, \HCO{}, and HCN ($J=1\rightarrow0$) emission across diverse regions of the Perseus and Serpens …

Contributions to late Ediacaran geobiology in South China and southern Namibia
… as their taxonomic affinities, paleoecology, and morphology. All of these factors were examined through taphonomic investigations and this can be seen in the analytical path through my chapters. In chapter two I examined the preservation of trace fossils in the late Ediacaran. In chapter three I …

Synthesis of III-V nitride nanowires with controlled structure, morphology, and composition
… nanowires with control over material structure, morphology, and composition. First, GaN nanowires were synthesized with control over nanowire orientation, morphology, and defect density. Substrate orientation was used to control whether nanowires grew preferentially in the polar [0001] direction …
