Structural and magnetic investigation of Fe3+ and Mg2+ substitution into the trigonal bipyramidal site of InGaCuO4

Creator:: Grajczyk, Rosa, Berthelot, Romain, Muir, Sean, Sleight, A. W., and Subramanian, M. A.
Abstract:: The solid solutions of InGa₁₋ₓFeₓCuO₄, InFeCu₁₋ₓMgₓO₄, and InGa₁₋ₓFeₓCu₁₋ₓMgₓO₄ were synthesized and characterized through the use of X – ray and neutron diffraction, and DC – magnetism measurements. All compositions of InGa₁₋ₓFeₓCuO₄ are single phase and crystallize in the R3m space group, but a transformation to the spinel InFeMgO₄ structure was...

The infrared spectrum of the nitrate ion in various crystalline environments

Creator:: Stewart, Julie Lingscheid
Abstract:: The infrared absorption spectra in the out-of-plane bending (v₂) region of potassium nitrate were studied for three phases. Several types of sampled were used: nujol mulls, fused samples, and N¹⁴-N¹⁵ isotopic mixtures. The existence of three of the reported polymorphic phases was confirmed by the spectra. The transitions between phase...

Prediction and Measurement of Polycyclic Aromatic Hydrocarbons (PAHs) Transformation Products in the Environment.

Creator:: Titaley, Ivan A.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are a group of environmental contaminants consisting of fused benzene rings. Parent-PAHs, methylated-PAHs (MPAHs), and PAHs with molecular weight of 302 a.m.u (MW302-PAHs) are considered as unsubstituted-PAHs. These unsubstituted-PAHs undergo transformation reactions resulting in the formation of PAH-transformation products (PAH-TPs), or substituted-PAHs, including nitrated-, oxygenated-, and...

Ionic Strength and pH: A Look at Nanostar Stability

Creator:: Aldous, Tanner J. E.
Abstract:: Nanostars have many potential applications, particularly in biomedicine, such as drug delivery, detection assays, and even cancer treatment. Seeing how their plasmon changes in response to changes to the environment of the nanostars can give us an insight to the stability of the nanostars. Our current studies involve the effect...

Probing structural evolution along multidimensional reaction coordinates with femtosecond stimulated Raman spectroscopy

Creator:: Frontiera, Renee R., Fang, Chong, Dasgupta, Jyotishman, and Mathies, Richard A.
Abstract:: Mapping out multidimensional potential energy surfaces has been a goal of physical chemistry for decades in the quest to both predict and control chemical reactivity. Recently a new spectroscopic approach called Femtosecond Stimulated Raman Spectroscopy or FSRS was introduced that can structurally interrogate multiple dimensions of a reactive potential energy...

The identification and quantitation of complex polycyclic aromatic hydrocarbon mixtures in environmental samples using comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry

Creator:: Manzano, Carlos A.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous contaminants and are mostly products of the incomplete combustion of organic material. PAHs are often found in environmental samples as a complex mixture of isomers. In addition, the same sources that produce complex PAH mixtures also produce other poorly characterized mixtures of organic compounds,...

The atmospheric chemistry of particulate-bound polycyclic aromatic hydrocarbons : concentration, prediction, laboratory studies, and mutagenicity

Creator:: Jariyasopit, Narumol
Abstract:: The trans-Pacific atmospheric transport of particulate matter (PM)-bound polycyclic aromatic hydrocarbons (PAHs) to remote sites in western North America has been well documented and has triggered research questions regarding to atmospheric transformation of PM-bound PAHs and the potential impacts on human health from their inhalation exposure. In this dissertation, field...
