Polyoxoniobates: fundamental solubility trend and their application in solution and on the surface of thin films

Creator:: Rahman, Tasnim
Abstract:: Polyoxometalates (POMs) are anions consisting of three or more early transition metals ™ (Gr V and VI) oxoanions (in their highest oxidation state) linked together by a shared oxygen bond to form a 3D framework. Polyoxometalates (POMs) are a rapidly growing class of metal oxo clusters with a wide range...

Formation of hybrid supramolecular assemblies using biological molecules and transition metals

Creator:: Smith, Rachelle M. S.
Abstract:: Naturally occurring assemblies, such as DNA and proteins, utilize intermolecular forces (i.e H-bonding and van der Waals) to assemble. Utilizing these electrostatic interactions has only just started in the past five decades to be a tool used in synthetic chemistry in what is known as supramolecular chemistry. Supramolecular chemistry has...

Uranyl Peroxide Cluster Formation Pathway and the Role of the Alkali Counterion

Creator:: Arteaga, Ana
Abstract:: Uranyl peroxide clusters are the newest family of polyoxometalates, discovered in 2015. Although this family is new, over 70 topologies have been reported. However, we lack the fundamental understanding of assembly mechanisms, particularly the role of the alkali countercations. Here, we use a wide range of solution and solid-state characterization...

Exploring the Distinct Solution Behavior of Isostructural Polycoltanates

Creator:: Fullmer, Lauren
Abstract:: Polyoxometalates are a rapidly growing class of discrete metal oxide clusters with a wide range of applications including functional materials. These anionic clusters of the group V and VI transition metals are inexpensive and non-toxic. Within group V polyoxometalates, niobium and tantalum chemistry has been underdeveloped owing to their unique...

Isolation of New Niobium clusters with Alkali Carbonate

Creator:: Feng, Ching-Lei
Abstract:: Polyoxoniobates (PONbs) are attracting great attention in recent years due to its novelty as well as a variety of geometrical presentations in different pH conditions. In this paper we are reporting the reaction of tetramethyl-decaniobate ([(CH3)4N]6[Nb10O28]) with alkaline carbonates to observe the periodic trend of alkaline ions interacting with the...

Synthesis and Characterization of Novel Metal-Oxo Clusters as the Building Blocks in Nature and Synthesis

Creator:: Amiri, Mehran
Abstract:: Metal-oxo clusters can be described as soluble pieces of metal-oxide frameworks. Metal-oxo clusters are also the building blocks for the Metal-Organic Frameworks (MOFs) and coordination polymers. A better knowledge of metal-oxo clusters helps fundamentally understand geosciences, molecular engineering, catalysis, single-molecule magnetism, and MOFs for synthesis, design, and modification of these...

Synthesis and Characterization of Alkylammonium Salts of Butyltin-Polyoxotungstates for Thin Film Functionalization

Creator:: Olsen, Morgan R.
Abstract:: Metal-oxo clusters are discrete, soluble pieces of bulk metal oxide. Cluster size, monodispersity, and chemical properties allow for potential use as solution-based precursors for functional metal oxide films. Classical monoalkyltin-oxo clusters are either charge neutral or stabilized by anions. The structure of Cs₄.₅H₂.₅[(BuSn)₃(α-SiW₉O₃₇)]*2H₂O enables its use in established ion exchange...

Organic/Inorganic Hybrid Materials of Uranyl Peroxide Clusters and Uranium Minerals

Creator:: Neal, Harrison A.
Abstract:: Frontier research of non-aqueous actinide clusters is discussed. Since the inception of the uranyl peroxide clusters over the last decade, they have only been synthesized and characterized as solid crystals and in aqueous solution. This thesis provides thorough characterization of aqueous uranyl clusters and the first demonstration of uranyl cluster...

Using Metal-Oxo Clusters to Expand Actinide Chemistry

Creator:: Colliard, Ian
Abstract:: A molecular approach to metal oxides allows to the study to fundamental bonding and formation behavior for such metals. Moreover, the molecular nature of such oxides or metal-oxo clusters allows the possibility of exploitation of the properties of the parent oxides. The tetravalent metals, in specific, (M=Zr, Hf, Ce, Th,...
