High resolution techniques for the measurement of component and device performance
… parameters and characteristics, by making use of high precision measurement techniques and incorporating a PC-based data acquisition system. An accurate and versatile measurement-card, employing a 12-bit analogue-to-digital converter, was designed and developed. The card, which plugs directly into …

Microstructure and Microchemistry of Rapidly Solidified Nickel-Base Powders
… and conventional (CTEM) modes. Using these high resolution techniques, it was possible to study the morphologies of the resultant microstructures and the associated chemical segregation on a very fine scale. Bulk undercooling experiments were also conducted and the microstructures of these …

Evaluation of null subtraction imaging and interpolation techniques for ultrasound B-mode
… attempts have been made to improve the lateral resolution through various adaptive and non-adaptive techniques. While each technique has its advantages and disadvantages, there are some challenges common to all methods. In particular, improvements in lateral resolution are often accompanied by a …

Single-molecule studies of alpha-synuclein and abeta in Parkinson’s disease derived biofluids
… internal reflection fluorescence imaging, super-resolution, and high-resolution techniques, we determined an efficient way of separating a heterogeneous protein mixture by size using a sucrose density gradient centrifugation in chapter 5. We showed that the small aggregates below 200 nm are the …

High Resolution Optical Tweezers for Biological Studies
In the past decades, numerous single-molecule techniques have been developed to investigate individual bio-molecules and cellular machines. While a lot is known about the structure, localization, and interaction partners of such molecules, much less is known about their mechanical properties. To …

Quantitative Measurements of Force Distribution in Single and Multi Cellular Systems
… of cellular events in vivo are restricted since high resolution techniques characterizing cell functions are not suitable for living organism. In respect to tissue culture techniques, introduction of artefacts in mammalian cells cultured on flat, rigid and non-natural two dimensional surfaces is …

Experimental investigation of carrier mobility degradation in metal oxide semiconductor field effect transistors of high permittivity gate dielectrics
… aggressive scaling gives rise, among others, to high gate tunnelling currents in contemporary silicon dioxide (SiO2) based Metal-Oxide- Field Effect Transistors (MOSFETs). SiO2 is therefore expected to be replaced in future technologies with alternative dielectrics. Several dielectrics with high …
