Exciplex Tuning And Optical Memory Studies For Dicyanoargentate(1) And Dicyanoaurate(1) Ions Doped In Potassium Chloride Crystals Extension To Mixed Metal Gold And Silver Systems, Samanthika Ruvinie Hettiarachchi
Exciplex Tuning And Optical Memory Studies For Dicyanoargentate(1) And Dicyanoaurate(1) Ions Doped In Potassium Chloride Crystals Extension To Mixed Metal Gold And Silver Systems, Samanthika Ruvinie Hettiarachchi
Electronic Theses and Dissertations
Exciplex tuning and optical memory behavior of [Ag(CN)2-] and [Au(CN)2-] ions doped in KCl host crystals, pure KAg(CN)2, and pure KAU(CN)2 have been studied. Additionally, d10-d10 (KAu(CN)2-KAg(CN))2) and d10-d8 (KAu(CN)2, KAg(CN)2- K2Pt(CN)4) mixed metal systems have been synthesized and characterized. Several ultraviolet and visible emission bands are observed for [Ag(CN))2-] and [Au(CN)2-] ions doped in KC1 host crystals. Each emission band becomes dominant at a characteristic excitation …
Simulation Of Structure, Dynamics And Electron Diffraction Patterns Of Heterogeneous Clusters Armn2N, W. H. Jinasena
Simulation Of Structure, Dynamics And Electron Diffraction Patterns Of Heterogeneous Clusters Armn2N, W. H. Jinasena
Electronic Theses and Dissertations
The nitrogen-argon system provides a useful paradigm for studying segregation and mixing behavior in heterogeneous clusters. Using three realistic pair potentials corresponding to argon-argon, nitrogen-nitrogen and argon-nitrogen interactions, the structures and thermodynamics of Arm(N2)n, clusters are investigated. Comparison of these results to previous simulation results on neat argon and nitrogen clusters is made. The initial focus of the study is the series of thirteen particle clusters of Arm(N2)13-m (0 ≤ m ≤ 13); molecular dynamics in the microcanonical ensemble is the principle simulation tool. The icosahedral nitrogen-argon clusters …
Stabilization Of Rutile-Related Thin Film On Tio2 Substrates, Youngnam Cho
Stabilization Of Rutile-Related Thin Film On Tio2 Substrates, Youngnam Cho
Electronic Theses and Dissertations
Conducting metal oxide thin films are of broad interest because they have a wide variety of magnetic and electronic properties. Materials exist that range from superconducting to insulating, are ferromagnetic and are ferroelectric. These properties make thin conducting oxide films attractive for many industrial applications. A class of metal oxides exists that adapt the rutile crystal structure; the structure of the mineral rutile, TiO2. These metal oxides have the general formula MO2 where M is a metal cation of valence +4. Metal oxides crystallizing in the rutile structure also display a wide variety of physical properties. The …
Effect Of Kraft Pulping On Oxygen Delignification, Haixuan Zou
Effect Of Kraft Pulping On Oxygen Delignification, Haixuan Zou
Electronic Theses and Dissertations
The objective of the study reported here was to investigate experimentally the effect of the major Kraft pulping variables on the response of brownstock pulps to medium consistency oxygen delignification. Kraft pulping was performed on mixed Northeastern hardwood chips in a laboratory rocking digester. Kraft pulps of kappa number 16 and 20 mL KMnO4 were produced by pulping under a variety of conditions. The effective alkali (EA) charged to the digester was varied over the range of 12 to 21% while the sodium sulfide content of the pulping liquor was varied between 0 to 30% sulfidity. Cooking temperatures of …
Impact Of Preservative Treatments And Fungal Exposure On Phenolic Fiber Reinforced Polymer (Frp) Composite Material Utilized In Wood Reinforcement, Cihat Tascioglu
Impact Of Preservative Treatments And Fungal Exposure On Phenolic Fiber Reinforced Polymer (Frp) Composite Material Utilized In Wood Reinforcement, Cihat Tascioglu
Electronic Theses and Dissertations
When wood products are exposed to environmental conditions conducive to biodeterioration, wood preservation becomes a necessity, especially when long-term utilization is desired. Although considerable literature exists on the treatment of laminated timbers and wood composites with wood preservatives, almost no information is available on the exposure of Fiber Reinforced Polymer (FRP) composites to wood preservative chemicals. In this work, FRP material was treated with common preservative chemicals and the effect of wood preservative treatments on mechanical properties of FRP material were investigated. Although the longitudinal elastic modulus was unaffected, some longitudinal strength losses were recorded for CCA and CDDC (water …
A Study Of The Photodegredation Of Carbaryl: The Influence Of Natural Organic Matter And The Use Of Silver Zeolite Y As A Catalyst, Marsha Kanan
Electronic Theses and Dissertations
The photodegradation of carbaryl in the presence of Suwannee River natural organic matter (NOM) as well as the presence of AgY zeolites was studied. Two NOM samples were purchased in 2000 and 2001 and labeled as NOM-2000 and NOM-2001, respectively. The synchronous-scan luminescence spectra (SSLS) indicate the presence of different luminophores in the two samples. This suggests that although the compositions of the two NOM samples are similar, isomers composing the NOM mixtures are different. This difference was observed in the effect the two Suwannee River NOM samples had on the photodegradation of carbaryl. In particular, the photodecomposition of carbaryl …
