DEGENERATIVE TRANSFER LIVING ZIEGLER-NATTA POLYMERIZATION OF α-OLEFINS
(2005-12-04)
A degenerative transfer (DT) living Ziegler-Natta polymerization system based on the cyclopentadienyl amidinate zirconium complex, (h5-C5Me5)ZrMe2[N(t-Bu)C(Me)N(Et)] (19), has been studied in detail. Compound 19 is an ...
ELECTROCHEMICAL OXIDATION KINETICS OF HYDROGEN AND HIGHER HYDROCARBON FUELS ON SOLID OXIDE FUEL CELLS.
(2007-11-27)
Solid oxide fuel cells (SOFCs) are promising electrochemical energy converting devices due to their ability to use not only hydrogen but also hydrocarbons as a fuel. Although conventional SOFCs with Ni/YSZ anodes and ...
Ethylene Polymerization Using a Zirconium Amidinate Supported Catalyst
(2004-05-07)
A series of W. R. Grace Davison IOLA(TM), methylaluminoxane-silica (MAO/Silica) and MAO/IOLA support materials were used to activate and immobilize a zirconium amidinate single site catalyst of the formula Cp*ZrMe2[tBuNC(Me)NCEt]. ...
Homoleptic Naked Clusters of Endohedral Zintl Ions
(2006-03-31)
Nanoclusters are of interest because of their remarkable catalytic properties and their application in nanotechnology fields. There is a strong preference toward bimetallic systems due to their superior catalytic properties ...
Synthesis and Characterization of Binary Clusters to Controllable Binary Nanoparticles "The New Role of Zintl Anions"
(2004-10-27)
Zintl anions are best described as polyatomic main group clusters (i.e. E73-; E = P, As, Sb) with structures characteristic of isoelectronic clusters (i.e. hydrocarbon and borohydride clusters). Combining these main ...
Reactions of Zintl ion Pb9 with Gold Precursor PPh3AuCl
(2006-12-10)
Transition metal main group clusters have been studied extensively as models for heterogeneous catalysts and metal surface reactions. In this thesis, reactions of Group 14 Zintl ion cluster Pb94- with the Au precursor ...
Intercalated MoS2 Nanoparticles for Enhanced Dispersion in Smokes and Obscurants
(2003-12-05)
The intercalation of MoS2 with diethyl oxalate (DEO) and Meldrum's Acid (MA) has been achieved via an exfoliation and reflocculation process. Ethyl diazoacetate (EDA) did not intercalate under identical conditions. The ...
Living Coordinative Chain Transfer Polymerization of 1-Alkenes
(2008-12-05)
A novel polymerization method, living coordinative chain transfer polymerization (CCTP), was recently developed with monocyclopentadienyl monoamidinate (CpAm) Group 4 metal complexes, which were previously applied for the ...
Arsenic(III) Speciation in Sulfidic- and Carbonate-Containing Waters; Thioarsenites as Ligands for Ag(I), Pb(II) and Hg(II)
(2004-11-22)
This dissertation has two objectives; the first is to investigate speciation of three d10 metals (Ag(I), Hg(II) and Pb(II)) in sulfidic solutions containing As(III) to determine if thioarsenite could act as a ligand for ...
Examination of Dynamic Processes in Living Ziegler-Natta Polymerization and New Polypropylene Architectures through Bimolecular Control
(2006-11-24)
The cationic cyclopentadienyl zirconium acetamidinate (CPZA) complex {Cp*ZrMe[N(Et)C(Me)N(tBu)]}[B(Csub6 Fsub5)sub4], (Cp* = ηsup5-Csub5Mesub5) generated through activation of Cp*ZrMesub2[N(Et)C(Me)N(tBu)] via protonolysis ...
