Mechanistic studies of polyhalogenated benzenes

Creator:: Herbelin, Sharon Maley
Abstract:: Polyhalogenated benzenes have been analyzed by standard electron capture chemical ionization mass spectrometry (ECCI/MS), and electron monochromator mass spectrometer (EM/MS) systems. The EM/MS experiments distinguished electronegative compounds (especially isomers) by transient negative ions (TNIs) of the same mass but differing energies and/or the formation of distinct TNIs of different masses...

Photoresist and ion-exchange chemistry of HafSOx

Creator:: Telecky, Alan J.
Abstract:: The chemistry of hafnium oxide based and materials are described in the context of ion exchange and lithography. HafSOx, represented by the composition HfO₂₋[subscript x](SO₄)x, is described to possess a significant capacity towards ion exchange in acidic and basic solutions, enabling films of HafSOx to be cleanly and readily be...

Per- and Polyfluoroalkyl Substances (PFASs) and Aqueous Film-Forming Foam Impacted Sites : New PFAS Discovery and Sorption of Anionic, Zwitterionic, and Cationic PFASs

Creator:: Barzen-Hanson, Krista A.
Abstract:: Public attention and concern about per- and polyfluoroalkyl substances (PFASs) are increasing due to detection of PFASs in drinking water supplies, the environment, including remote locations, and wildlife and to the lowering of the federal health advisory levels of perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) in drinking water. Aqueous film-forming...

Structure-property relationships in oxides containing select platinum group metals

Creator:: Gatimu, Alvin J.
Abstract:: Oxide materials exhibit a wide variety of structures and properties. In particular, transition metal oxides tend to be highly stable while exhibiting a wide range of properties that can be used for numerous applications. This work focuses on investigating how the structures’ of 4d and 5d transition metal oxides influences...

New luminescent materials and high-performance solution-processed oxide thin films

Creator:: Jiang, Kai
Abstract:: Crystals of an incongruent-melting compound, Ba₃MgSi₂O₈, were grown by the flux method and its structure was determined by single crystal X-ray diffraction methods. Ba₃MgSi₂O₈ crystallizes in trigonal space group P-3[bar]m1 with a = 5.6123(3) Å, c = 7.2667(9) Å and Z = 1. Eu²⁺ ions prefer one crystallographic Ba site...

Iron and copper chalcogenides : photovoltaic absorber candidates and YZrF7 : a new upconversion host, Iron and copper chalcogenides : photovoltaic absorber candidates and YZrF₇ : a new upconversion host

Creator:: Jieratum, Vorranutch
Abstract:: The materials Fe₂(Si,Ge)(S,Se)₄, Cu₃PS[subscript 4-x]Se[subscript x] (0 ≤ x ≤ 4), and Cu₃PxAs[subscript 1-x]S₄ (0 ≤ x ≤ 1) have been synthesized and studied as new earth-abundant absorbers for single and multijunction photovoltaic cells as well as solar fuel generation. The synthesis, single-crystal growth, and optical and electrical properties of...

Copper and iron chalcogenides for efficient solar absorption

Creator:: Platt, Heather A. S.
Abstract:: This dissertation outlines two approaches for improving the efficiency and reducing the cost of photovoltaic energy generation. First, the structures of known binary copper and iron compounds are used to choose the promising compositions Fe₂XS₄ (X = Si, Ge), Cu₃TaQ₄ (Q = Se, Te), and BaCuQ'F (Q' = S, Se,...

Aqueous niobium chemistry at low pH : new precursors for oxide thin films

Creator:: Park, Deok-Hie
Abstract:: Phosphate and peroxide stabilize new oxo-hydroxo niobium clusters in water at low pH. The clusters open a new chapter in aqueous niobium chemistry under acidic conditions. The clusters also produce atomically smooth, amorphous niobium oxide phosphate (NbPOx) thin films. Reaction pathways from cluster solutions to amorphous niobium oxide phosphate solids...

Aqueous chemistries for oxide electronics

Creator:: Meyers, Stephen T.
Abstract:: The variegated aqueous chemistries of metal cations are applied to the design and synthesis of non-toxic solution precursors suitable for additive printing of large-area oxide electronics. Polycondensation behaviors of aqueous Al+3 and PO4 +3 are manipulated in the deposition of atomically smooth amorphous aluminum oxide phosphate (AlPO) dielectric films. AlPO...
