Laser Processing Of Carbon Nanotube Transparent Conducting Films, Andrew Mann

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Transparent conducting films, or TCFs, are 2D electrical conductors with the ability to transmit light. Because of this, they are used in many popular electronics including smart phones, tablets, solar panels, and televisions. The most common material used as a TCF is indium tin oxide, or ITO. Although ITO has great electrical and optical characteristics, it is expensive, brittle, and difficult to pattern. These limitations have led researchers toward other materials for the next generation of displays and touch panels. The most promising material for next generation TCFs is carbon nanotubes, or CNTs. CNTs are cylindrical tubes of carbon no …

High Performance Two-Phase Thermosyphon For Energy-Efficient Refrigeration Applications: Modeling And Experiments, Chunlei Mei Dec 2013

High Performance Two-Phase Thermosyphon For Energy-Efficient Refrigeration Applications: Modeling And Experiments, Chunlei Mei

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

The Two-Phase Closed Thermosyphon (TPCT) is a device that transfers heat from its bottom to top and because phase change phenomenon happens both in its bottom and top, its performance is ten times better than pure metal. It has three heat transfer regimes, condenser, adiabatic section and evaporator. The mechanism of thermosyphon is the phase change cycle: liquid absorbs heat in evaporator and then vaporizes into vapor; finally the vapor condenses along the condenser wall and flow back to evaporator liquid pool. Firstly, detailed heat transfer mechanism will be discussed. Many empirical equations will be reviewed. Geometrically, TPCT contains three …

Does Lunatic Fringe Modify Itself?, Usman Aslam Dec 2013

Does Lunatic Fringe Modify Itself?, Usman Aslam

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Notch signaling plays an essential role in metazoan development, and dysregulation of its activity has been recognized as a cause for many diseases. The extracellular domain of the Notch receptor has numerous tandem epidermal growth factor-like repeats modified with O-fucose and O-glucose glycans that play important roles in Notch function. Elongation of O-fucose by β 3-N-acetylglucosaminyltransferases of the Fringe family is known to modulate Notch activity. In addition, preliminary data from the Haltiwanger laboratory suggests that one of the Fringe enzymes, Lunatic Fringe, may modify itself. Lunatic Fringe does not contain any epidermal growth factor-like repeats and is not known …

Structural And Biochemical Analysis Of The Hnrnpab Tandem Rrm Rna Binding Domain, Daniel Catt Dec 2013

Structural And Biochemical Analysis Of The Hnrnpab Tandem Rrm Rna Binding Domain, Daniel Catt

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Post-transcriptional trafficking of mRNA within the cell provides for spatial regulation of protein expression. Cis-acting localization elements known as zip codes located often in 3' untranslated regions (UTRs) of mRNA transcripts play a strong role in directing distribution within the cell through recognition by RNA-binding proteins. Hnrnpab is a protein with putative roles in this process with RNA-binding properties likely directed through tandem RNA Recognition Motifs (RRMs) that form a cooperative RNA Binding Domain (RBD). We purified this Hnrnpab RBD and carried out electrophoretic mobility shift assays (EMSAs) using the zip code region from the ActB gene to demonstrate high …

Identification Of Specific Residues Necessary For The Eviction Of H2a.Z-Containing Nucleosomes, Karole Nicole D'Orazio Dec 2013

Identification Of Specific Residues Necessary For The Eviction Of H2a.Z-Containing Nucleosomes, Karole Nicole D'Orazio

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

In this study, I investigated how the well-conserved histone variant H2A.Z is removed from promoters to prepare genes for transcription. H2A.Z is found at the majority of nucleosomes near promoters in place of the canonical histone H2A. Why H2A.Z is localized to gene promoters in all eukaryotes is unclear. One hypothesis is that H2A.Z marks nucleosomes for disassembly, thereby opening up promoters to give room for the transcription machinery to assemble. How H2A.Z-containing nucleosomes are removed from promoter sites is also unknown, but the Luk laboratory has recently found that ATP is necessary for this process. We propose that there …

Circulating Complexes Of The Vitamin D Binding Protein With G-Actin Induce Lung Injury By Targeting Endothelial Cells, Lingyin Ge

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Actin is the most abundant and highly conserved intracellular protein in all eukaryotic cells. Cell necrosis can release actin into the extracellular environment where conditions favor spontaneous generation of F-actin filaments. A robust extracellular actin scavenger system consisting of gelsolin and the vitamin D binding protein (DBP) has evolved to sever F-actin filaments (gelsolin) then bind G-actin monomers (DBP) for subsequent clearance. This study investigated the role of DBP in this process using the DBP null mouse that has a systemic deficiency of DBP. Intravenous injection of G-actin into wild-type (DBP+/+) and DBP null (DBP-/-) mice showed that, contrary to …

Structure And Assembly Of Saccharomyces Cerevisiae Outer Spore Wall, Pei-Chen Coney Lin Dec 2013

Structure And Assembly Of Saccharomyces Cerevisiae Outer Spore Wall, Pei-Chen Coney Lin

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

In Saccharomycs cerevisiae, spores are a quiescent, stress-resistant cell type, which can survive for extended periods of time in unfavorable conditions until nutrient conditions are suitable. The outer layers of the spore wall contain chitosan and dityrosine, which are macromolecules specific for the spore. These layers are critical for resistance of the spores to adverse environmental stresses. The dityrosine layer is an unique polymer component of cross-linked N, N'-bisformyl dityrosine. This layer provides a shield from protein-sized attack such as lytic enzymes. For structural studies, we took advantage of the insolubility of the spore wall materials by using solid-state NMR …

Structural Characterization Of Individual Domains Of An Energy Dependent Mitochondrial Protease, Faiza Sheikh

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

The ATP- dependent i-AAA protease pulls in and unwinds improperly folded and short-lived membrane proteins in order to maintain the integrity of the mitochondrial inner membrane. The i-AAA protease consists of an N-terminal domain, a single trans-membrane domain, a AAA ATPase domain and a metalloprotease domain. The role of the AAA domain is to unfold and translocate targeted proteins to protease domain where they are degraded. To further our understanding of the mechanism of this important enzyme, I sought to isolate and gain structural information on the individual domains of the i-AAA protease from the thermophilic eukaryote Myceliophthoya thermophile. I …

An Exploration Of Alkyne-Alkyne Cross-Coupling Reactions And Attempts Towards Controlled Polymerization Of Diiodooctatetrayne, Allison Black

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Polyynes are one-dimensional rigid carbon rods composed of alternating triple and single bonds. They have attracted much interest due to their electronic, optical, and physical properties. These carbon oligomers can serve as possible precursors to polydiacetylenes or graphitic ribbons, as subjecting ordered aggregates to heat and/ or irradiation can lead to topochemical polymerization. Furthermore, polyynes can act as models for understanding conjugation, and may be used to predict the properties of carbyne, the linear allotrope of carbon. In this work, model Stille and Cadiot-Chodkiewicz coupling reactions using iodoalkyne substrates were thoroughly investigated. Once optimal conditions were determined for each system, …

Part I. Stereospecific Synthesis Of Vinyl Iodides: Iododesilylation Of Homoallylic Alcohol Derivatives Part Ii. Model Studies, A Formal Synthesis Of (-)-Englerin A, And The Total Synthesis And Biological Evaluation Of New Englerin Analogs, Daniel Craig Elliott

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Part I. Vinyl iodides with defined geometry are important chemical building blocks. Their preparation by iododesilylation of the corresponding vinyl silane is an attractive method. Kishi et al. have shown that if iododesilylation is carried out with N-iodosuccinimide (NIS) in an acetonitrile/chloroacetonitrile mixture, one obtains vinyl iodides in which the geometry of the olefin is highly retained. By carrying out iododesilylation with NIS in hexafluoroisopropanol, Zakarian et al. have shown that the olefin geometry is also retained, but to a larger degree. Previously, the Parker group has applied this methodology to a synthetic study of trisubstituted vinyl iodides. Therein, they …

Untangling The Interactions: Structural Basis Of Nitric Oxide Regulated Cyclic-Di-Gmp Metabolism In Bacteria, Tanaya Lahiri

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Bacteria use numerous small molecules for cellular signaling. These primary and secondary messengers act within the cell to relay signal transduction and regulate distinct pathways. Among these the diatomic gas molecule nitric oxide (NO) and the nucleotide cyclic-di-GMP play central role in virulence, quorum sensing, and biofilm formation. In this dissertation, we have focused on H-NOX, a heme-nitric oxide/oxygen binding protein in the biofilm-dwelling bacterium Shewanella woodyi (Sw), which mediates NO-induced biofilm dispersal by modulating the activity of a dual-functioning diguanylate cyclase/phosphodiesterase enzyme that we have named HaCE, (H-NOX-associated cyclic-di-GMP enzyme). These enzymes tightly regulate the intracellular spatio-temporal concentrations of …

Macrocyclic Host-Guest Framework For Polymerization Of Diiodobutadiyne, Xianzhi Liu

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Conjugated organic polymers have optical and electronic properties that make them candidates for applications in organic field effect transistors (OFETs) and light emitting materials. Polydiacetylenes (PDAs) are an important branch of conjugated polymers with alternating poly(ene-yne) structure. The all-carbon polymer without any side groups is carbyne, which has only alternating single and triple carbon-carbon bonds. Carbyne provides a good opportunity to investigate the inherent properties of conjugated polymers. Polydiiododiacetylene (PIDA), a simple PDA with only iodine atom substituents, can be successfully obtained by the topochemical polymerization of the monomer diiodobutadiyne. This polymerization is achieved through the use of bis(nitrile) or …

Poly(Diiododiacetylene): A Potential Precursor For New All-Carbon Materials, Daniel Joseph Resch

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Poly(diiododiacetylene) (PIDA) is a polymer consisting entirely of carbon and iodine. The polymer is prepared by cocrystallizing a bis(nitrile) oxalamide host with the monomer diiodobutadiyne. These compounds are held together by a halogen bond and an ordered 1,4-topochemical polymerization occurs in the solid state. The formation of the monomer cocrystals was found to be highly solvent dependent. Acetonitrile was found to greatly improve the yield of cocrystals over solvents used in the past. Cocrystals could not be obtained from other solvents such as dimethoxyethane and acetone. THF did give some cocrystal but the yield was poor. The use of acetonitrile …

The Structural And Relative Stability Of Temperament In Young Children Based On A Laboratory-Observational Measure, Margaret Wegner Dyson Dec 2013

The Structural And Relative Stability Of Temperament In Young Children Based On A Laboratory-Observational Measure, Margaret Wegner Dyson

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Despite the continued debate regarding the structure of temperament in young children, it is often assumed that temperament traits demonstrate temporal stability over time. This research has relied predominately on parent-report measures. The present study used an alternative approach, a laboratory-observational measure (Laboratory Temperament Assessment Battery [Lab-TAB]), to examine the structural and relative stability of temperament traits in a community sample of young children (N = 440). Using structural equation modeling (SEM), we derived a similar five-factor structure consisting of the dimensions of Positive Affect/Interest, Sociability, Dysphoria, Fear/Inhibition, and Impulsivity vs. Constraint at both age 3 and 6 years, suggesting …

Investigation Of The Mouse Sperm Acrosome Reaction With Synthetic Glycopolymers, Linghui Wu Dec 2013

Investigation Of The Mouse Sperm Acrosome Reaction With Synthetic Glycopolymers, Linghui Wu

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

The sperm acrosome reaction (AR), an essential step in mammalian fertilization, is mediated by a highly species-specific interaction of sperm surface molecules with glycan moieties on the egg. Many previous studies indicate that a subset of terminal carbohydrate residues on the mouse egg zona pellucida (ZP) trigger the AR by cross-linking or aggregating receptors on the sperm membrane. However, the exact role of those carbohydrates in AR has not been identified and the mechanism underlying the induction of the AR still needs further investigation. To study this process, a series of synthetic glycopolymers were synthesized. The glycopolymer is composed of …

Auditory Classification Of Vehicles For Scene Understanding, Scott Bejan Kaghaz-Garan

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

There have been numerous studies on the classification of auditory signals. In contrast,there have been very few studies in the implementation and classification of vehicles using purely auditory signals. This thesis presents an implementation of auditory vehicle identification using support vector machines. It explores how granular classification can be, from what type of vehicle to what action the vehicle is preforming. The granularity of the classification will greatly aid in auditory scene understanding. The classifications are done with computational complexity in mind, so embedded systems can utilize the findings. A simple averaging algorithm will also be explored that aids in …

Extinction Risk Assessment As A Tool For Biological Conservation, Jessica Carol Stanton Dec 2013

Extinction Risk Assessment As A Tool For Biological Conservation, Jessica Carol Stanton

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Effective conservation of biological diversity requires accurate assessments of species extinction risks. Both under- and over-estimating extinction risks can have serious consequences. Overlooking species that are in need of conservation management can result in extinction or expensive recovery efforts. Misidentifying species which have stable populations as threatened can misdirect limited conservation resources or unnecessarily halt economic activity and development. I used a retrospective multi-modeling framework to explore the extinction of a once abundant and wide-spread North American species, the Passenger Pigeon (Ectopistes migratorius). I simulated three different types of anthropogenic impacts: harvest, habitat loss, and nest disturbance. I …

Systematic Modeling And Characterization Of Analog Circuits Using Symbolic And Data Mining Techniques, Cristian Ferent

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Analog circuit design activities mainly depend on designers' expertise and their ability to produce new designs by combining basic devices, sub-circuits, and ideas from similar solutions as the source for innovation. There are very few systematic methods that can characterize similarities and differences between analog circuits while maintaining the correlation between design variables, performance, and trade-offs. Moreover, many computer-aided design tools are focused only on routine tasks, like transistor sizing and layout design. This dissertation presents novel techniques to automatically characterize the analog design space based on feature uniqueness and variety and to perform systematic circuit comparisons using symbolic models. …
