This thesis is devoted to the study of the dispersion polymerization of methyl methacrylate in supercritical carbon dioxide (scCO2), using a poly(dimethylsiloxane) macromonomer (PDMS macromonomer) as stabilizer. Supercritical fluids (SCF) and SCF mixtures ...
The ruthenium(II) hexaaqua complex [Ru(H2O)6]2+ reacts with dihydrogen under pressure to give the h2-dihydrogen ruthenium(II) pentaaqua complex [Ru(H2)(H2O)5]2+.The complex was characterized by 1H, 2H and 17O NMR: d H = -7.65 ppm, J HD = 31.2 Hz, d O = -80 ...
Density functional theory was employed to investigate atomic layer deposition (ALD) mechanism of zirconia on Si(100)-2 X 1 surface with single and double hydroxyl groups. The ZrO2 ALD process using ZrCl4 and H2O as precursors involves two alternate deposit ...
The discovery, study, and implementation of the Co- and Mn-catalyzed hydrohydrazination and hydroazidation reactions of olefins are reported. These reactions are equiv. to direct hydroaminations of C-C double bonds with protected hydrazines or hydrazoic ac ...
Hydrogenation of C60 at 2 GPa and 723-823 K was performed with thermal decompn. of LiAlH4 as a hydrogen source. Anal. of hydrogenation products showed that the method can produce not only C60H36, but also hydrofullerides C60Hx with 44 < x < 52. Unlike othe ...
Accelerated bleaching, photobleaching and mineralization of the non-biodegradable azo-dye, Orange II, was obsd. with oxone in solns. with Co2+-ions. The bleaching rate of Orange II in the dark was found to follow a first-order kinetics with respect to [Co2 ...
This thesis describes the synthesis, characterisation and macroscopic manipulation of carbon nanotubes. Two interconnected aspects were investigated: (i) growth of carbon nanotubes by catalytic chemical vapour deposition of acetylene and (ii) assembly and ...
In analogy to the authors' successful PX2+ insertion reactions, an AsX2+ insertion route was explored to obtain new arsenic halogen cations. Two new salts were prepd.: AsBr4+[Al(OR)4]-, starting from AsBr3, Br2 and Ag[Al(OR)4], and I2As-PI3+[Al(OR)]4 from ...
The goal of our project (HES-SO n°11246) is to develop chemometric methods that enhance the development of chemical reactions. Semi-batch experiments are performed using a fully automated chemical reactor. Real-time analytical data, infrared (IR) spectra f ...
Elucidating the structural properties of early intermediates (protofibrils) on the fibril formation pathway of Abeta and alpha-synuclein, the structural relationship among the different intermediates and their relationship to the structure of the amyloid f ...
