Functional and Responsive Polymers via Controlled Radical Polymerization

This Thesis is built around 4 topics, which share in common that they all take advantage of the assets of controlled radical polymerization to either (i) prepare well-defined model systems to address fundamental research questions with regard to the sensit ...

Formaldehyde stabilization facilitates lignin monomer production during biomass depolymerization

Yiming Li, Jeremy Luterbacher, Masoud Talebi Amiri, Florent Emmanuel Héroguel, Ydna Marie Questell-Santiago, Li Shuai

Practical, high-yield lignin depolymerization methods could greatly increase biorefinery productivity and profitability. However, development of these methods is limited by the presence of interunit carbon-carbon bonds within native lignin, and further by ...

Halide removal from aqueous solution by novel silver-polymeric materials

Urs von Gunten

The objective of this study was to analyze the behavior of a new material, silver-doped polymeric cloth (Ag-cloth), in the removal of bromide and iodide from waters. Silver is immobilized on the cloth, guaranteeing selective adsorption of the halide ions a ...

Formation Mechanisms and Structural Properties of Aluminium-Chromium Based Oxynitride Thin Films Synthesized by Physical Vapor Deposition

Hossein Najafi

Oxynitride thin films, a novel class of mixed anionic solid structures, have gained an intense interest during recent years related to the unique interplay of oxygen (O) and nitrogen (N) with metals in the material structure. This matter can result in spec ...

Kinetic studies on the first dihydrogen aquacomplex, [Ru(H2)(H2O)5]2+: Formation under H2 pressure and catalytic H/D isotope exchange in water

André Merbach, Lothar Helm, Gabor Laurenczy, Oleg Yazyev, Pascal Grundler

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 ...

Stereoisomer-uniform olefins

Homogeneous stereoisomeric olefins of the general formula I (R1 and R2 = alkyl, R3 = H and(or) alkyl) were prepd. by reacting a phosphorus ylide (general formula Ar3P+:C-HR) and a carbonyl compd. R2COR3 with stoichiometric amt. of a strong base, followed b ...

Trans-selective olefin synthesis

Primarily trans-olefination has been achieved by rapid equilibration of erythro- and threo-betaines. The betaine ylides (I) are formed by the treatment of betaine-LiX adduct with PhLi or n-BuLi in 1:1 ether-tetrahydrofuran at -30 Deg. The equil. between th ...
