Feasibility of Spinal Neuronavigation and Evaluation of Registration and Application Error Modalities Using Optical Topographic Imaging
… using frame-based stereotaxy. Advances in imaging and computing power have led to the development of modern frameless three-dimensional (3D) computer-assisted navigation (CAN), employed across multiple surgical disciplines. In spinal surgery, CAN may guide implant placement, bony …

Localised Dosing and Nanodetection Using a Novel Scanning Ion Conductance Microscope and Its Application to Alzheimer's Disease
… microscopy (SICM) is a technique for non-contact topographic imaging. In this thesis, a biophysical investigation into Alzheimer's Disease (AD) was carried, with toxic oligomers dosed locally and quantitatively on to single astrocytes using SICM and simultaneously monitoring the response of the …

Residual Stress Effects on Power Slump and Wafer Breakage in GaAs MESFETs
… to have less stress than SiN passivated wafers. Topographic imaging suggests that SiN passivated wafers have larger flaws than SiON passivated wafers, and that the distribution of flaw size among SiN passivated wafers is wider than the distribution of flaws in SiON passivated wafers. These flaws …

In situ electron microscopy of nanomaterials dynamics in heterogeneous phase environments
… simultaneous acquisition of 2D projection and 3D topographic imaging in environmental TEM (ETEM) setup to analyze the structure dynamics of supported catalytic nanoparticles during heating and gas exposure. Particle migration and coalescence dominated above an onset temperature that depends on the …

Variable Temperature Scanning Tunneling Microscopy Study of a High Temperature Superconductor Bi2Sr2CaCu2O8+d
We have used a custom-built scanning tunneling microscope (STM) to investigate the electronic states of a slightly underdoped high-TC superconductor Bi2Sr2CaCu2O8+d as a function of temperature. We have demonstrated for the first time that atomicallyresolved spectroscopic studies at elevated …
