Magnetic particles for selective extraction of trace analytes in microfluidic devices

Creator:: Tennico, Yolanda H.
Abstract:: The development of micro total analysis systems (µTAS), also called “lab-on-a-chip”, or microfluidic analysis systems, is presented in this dissertation. Various research areas, covering subjects from magnetic particles synthesis to novel microchip fabrication techniques, are explored to develop a lab-on-a-chip system capable of performing magnetic bead-based bioassays. These devices are...

Examination of low-lying rovibrational states of D₃[subscript h] oblate top molecules using high resolution FTIR and coherent anti-Stokes Raman spectroscopies

Creator:: Kirkpatrick, Robynne
Abstract:: Interesting rovibrational characteristics of two D_(3h) oblate symmetric top molecules were studied. Hamiltonian models for the fine rovibrational level structure of [1.1.1]propellane (propellane) were obtained for many low-lying modes. Ground state parameters (GSP) that are not exclusively K^(2n) dependent were obtained. Initially, the GSP were used in conjunction with density...

Structure-property Relationships of Transition Metal Oxides Containing Precious Metals

Creator:: Hapuraja Pathirannehelage, Vidhara H. P.
Abstract:: This dissertation presents a study of structure-property relationships within 3d/4d metal oxides containing precious metals through detailed structure refinements using high-resolution neutron and X-ray diffraction data along with exploration of the resultant properties. Oxides of 4d or 5d transition metals tend to show new topological phases due to significant spin-orbit...

Hydrogen production via a sulfur-sulfur thermochemical water-splitting cycle

Creator:: AuYeung, Nicholas J.
Abstract:: Thermochemical water splitting cycles have been conceptualized and researched for over half a century, yet to this day none are commercially viable. The heavily studied Sulfur-Iodine cycle has been stalled in the early development stage due to a difficult HI-H₂O separation step and material compatibility issues. In an effort to...

Thin-Film Dielectric Structure of Spin-Coated ZrO2 from Aqueous Inorganic Solution

Creator:: Moreno Luna, Hidekel A.
Abstract:: An inorganic aqueous precursor for the deposition of ZrO2 thin films via spincoating was developed. Hydrolysis and condensation chemistries of ZrOCl₂·8H₂O were used as the principal reactions to guide the synthesis. Refractive index, n, for a film annealed at 300 °C at 550 nm was measured to be n=1.97 by...

Synthesis and Solution Behavior of Tetravalent Metal Clusters with Ammonium Counterions

Creator:: Brown, Jessica C.
Abstract:: Global interest in reducing carbon emissions by use of alternative energy sources makes nuclear energy production and the impacts of the nuclear energy cycle relevant. Studying the aqueous speciation of tetravalent metals commonly used for nuclear energy (uranium, thorium, plutonium) can inform us of general metal properties and their behavior...

Modeling Arctic melt ponds using a resolved ice model with GCM forcing

Creator:: Collins, Lee E.
Abstract:: The albedo of Arctic sea ice depends greatly on the formation of melt ponds. These ponds form in depressions on the ice as surface snow melts during the summer months, and their location is determined mainly by the initial snow topography. Using a high resolution sea ice model forced with...

Detection techniques for biomolecules using semi-conductor nanocrystals and magnetic beads as labels

Creator:: Chatterjee, Esha
Abstract:: Continued interest in the development of miniaturized and portable analytical platforms necessitates the exploration of sensitive methods for the detection of trace analytes. Nanomaterials, on account of their unique physical and chemical properties, are not only able to overcome many limitations of traditional detection reagents but also enable the exploration...

Organic Crystalline Solids : Investigating their Capability, Storage Mechanism and Structural Evolution in Dual-Ion Batteries

Creator:: Rodríguez Pérez, Ismael A.
Abstract:: Widespread installation of renewable energy sources, such as wind and solar, has been delayed by the lack of suitable stationary energy storage solutions. Current large-scale technologies, such as pumped hydro and compressed air, are geographically restricted. This is where electrochemical energy storage - batteries or hybrid capacitors can play a...

Tracking Photoinduced Primary Events with Femtosecond Stimulated Raman Spectroscopy and Calculations

Creator:: Wang, Yanli
Abstract:: Femtosecond stimulated Raman spectroscopy (FSRS) is a powerful ultrafast technique which can track photoinduced excited state structural events on femtosecond (fs) to picosecond (ps) timescales. In addition to high temporal and spectral resolutions, FSRS provides a broad spectral window from ca. 100—2000 cm-1 for detection, enabling the direct mapping of...
