Construction of a 10nm planar confinement cell for helium-4 and studies on the empty cell
During the construction of the cell, unexpected bonding problems were encountered. Therefore, this work discusses the numerous attempts and new bonding techniques, like vacuum bonding, that were applied in order to solve ...
Hybrid semiconductor nanomagnetoelectronic devices
The subject of this dissertation is the exploration of a new class of hybrid semiconductor nanomagnetoelectronic devices. In these studies, single-domain nanomagnets are used as the gate in a transistor structure, and the ...
Kinetic theory of anisotropic magnetoresistance in copper
The anisotropic magnetoresistance (MR) in Copper (Cu) is studied, using kinetic theory and a simplified Fermi surface with necks. Cu's Fermi surface has "necks" located in the <111> direction. If the electron, which ...
Study on manganese doped III-V semiconductors and spintronic devices
Manganese doped III-V semiconductor materials, such as GaAs/Mn digital alloys and GaMnSb random alloys, are prepared with low temperature molecular beam epitaxy (LTMBE) technique. Magnetic properties of those materials are ...
The development of new nanoelectrospray techniques and a noble stable isotope labeling method for bioanalytical mass spectrometry
With the advance of science, the demand of new analytical techniques with much higher sensitivity increases. Especially, in the mass spectrometry community, one of the successful responses to that kind of demand is the ...
Mechanistic studies for transesterification of RNA analogues catalyzed by a dinuclear zinc(II) complex
RNA cleavage, as catalyzed by self-cleaving ribozymes, is dependent on metal ions involved in the active sites. To better understand the roles of the metal ions and to develop efficient artificial RNA-cleaving agents, ...
Tellurium heterocycles: New tellurophenes and an optimized route
The synthesis of new tellurophenes has been achieved. Facilitating this work is the process development of optimized routes to the requisite precursor molecules. Further, the work required to furnish the scaffold for ...
Robust microbial fabrication of plant pharmaceuticals: Complexities and solutions
Abstract not available.
Insight into the syntheses and the reactions of ethylene complexes of iridium (I) alkylphosphines
Arguably, one the most important reactions in organometallic chemistry today is nucleophilic attack on a coordinated olefin. Previous research has shown that platinum(II) complexes could be used as catalyst precursors for ...
Geologic map of MTM quadrangles -15257 and -20257 of western Hesperia Planum, Mars
The volcanic edifice of Tyrrhena Patera (approximately -22°N, 252°W), Mars, stands 1800 m above the surrounding plains of Hesperia Planum, approximately 2000 km northeast of the center of the Hellas impact basin. Shallow ...
