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...

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,...

Total Synthesis of Isotopologues of Xanthohumol and its Congeners for Biological Studies

Creator:: Plagmann, Layhna S.
Abstract:: Xanthohumol [XN, (E)-6´-methoxy-3´-(3-methylbuten-2-yl)-2´,4´,4´´-trihydroxychalcone], the principal prenylated chalcone from hops, and its 2,3-dihydro- (DXN) and O6-desmethyl-2,3-dihydro- (DDXN) congeners, are of potential utility for the amelioration of metabolic syndrome; however, their complex bioactivity profiles cannot be properly studied and understood without access to appropriately produced synthetic materials. In the first part of...

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...

Semi-volatile fluorinated organic compounds in Asian and Pacific Northwestern U.S. air masses

Creator:: Piekarz, Arkadiusz M.
Abstract:: Current studies suggest that perfluorinated organic compounds, such as fluorotelomer alcohols (FtOHs) in the troposphere, may be precursors of perfluorocarboxylic acids and perfluorosulfonates in remote regions. Fluorinated organic compounds were investigated in archived extracts collected from remote locations in Okinawa, Japan (HSO) and Mount Bachelor, Oregon (MBO) during the springs...

Novel Charge Carriers for Aqueous Electrochemical Energy Storage

Creator:: Sandstrom, Sean K.
Abstract:: The continued long-term use of fossil fuels as a primary energy source has resulted in dramatic increases in greenhouse gas emissions and the associated concerns of climate change and environmental pollution. A key strategy to circumvent these issues is a global shift away from fossil fuels toward renewable energy sources....

Functionalization of carbon nanotubes for effective biosensing and potential biomedical applications

Creator:: Adenuga, Adeniyi A.
Abstract:: Since their discovery in the 1990s, the great potential of carbon nanotubes (CNTs) has made them a focus of many research endeavors, including their application as components of biosensors. The inherent chemical "inertness" of CNTs makes their application to biosensing a challenge. It is necessary to "decorate" their surfaces to...

Enantioselective Total Syntheses of Quinolizidine Lycopodium Alkaloid Cermizine D and Cytotoxic Marine Macrolide Mandelalide A

Creator:: Veerasamy, Nagarathanam
Abstract:: The enantioselective total synthesis of quinolizidine-containing natural product cermizine D and formal syntheses of senepodine G and cermizine C has been achieved. These natural products are members of the lycopodium alkaloids, which have attracted significant attention due to their exciting biological activities and the diverse structural scaffolds. Key steps in...

Fundamental Studies of the Structure-Property Correlations of Na-ion and K-ion Storage in Non-Graphitic Carbon

Creator:: Li, Zhifei
Abstract:: Grid-scale energy storage systems are urgently needed to increase the flexibility and rigidity of the grid for modern society and take full advantage of the renewable green energy resources such as solar energy and wind energy. Na-ion batteries (NIBs) and K-ion batteries (KIBs) have been emerged as one of the...

Rationalization and innovative design of asymmetric organocatalysts through computational investigation

Creator:: Johnston, Ryne Connell
Abstract:: My work on computing complex catalyzed organic transformations reveals that only a few subtle chemical factors, e.g. non-classical hydrogen bonding, (hyper)conjugation and steric effects, common across different catalyst manifolds are critical for catalysis and selectivity. Rational manipulation and exploitation of these factors has led to improved catalyst designs, which has...
