Catalyst immobilization techniques for continuous flow synthesis
… expand and evaluate techniques for immobilized catalyst systems relevant to continuous flow. Fundamental studies in characterizing mixing, dispersion, and residence time distributions in small scale continuous flow systems are also presented. Given the numerous benefits associated with studying …

Development of enzymatic biofuel cell based on carbon nanotube electrodes on porous silicon
… were synthesized directly, followed by enzyme catalyst immobilization on the CNTs. Laccase and glucose oxidase (GOx) were used as enzymatic biocatalysts, which were immobilized on the CNT walls and tips using an electrochemical technique. Cyclic voltammetry showed well-defined redox peaks which …

Amphiphile Phosphane für die Anwendung in neuen polaren Medien
… functionalised with ionic or polar groups for catalyst immobilization tasks. A point of main effort were imidazol- and imidazolium-groups who have not been systematically investigated before and to which the first part of this work has been dedicated. A novel synthesis of …

Hyperverzweigte Polyelektrolyte als Träger für lösliche, recycelbare Homogenkatalysatoren
Im Rahmen der vorliegenden Arbeit wurde die Mikroheterogenisierung von Homogenkatalysatoren durch ionische Anbindung an lösliche, makromolekulare Träger am Beispiel eines Rhodiumkatalysators untersucht. Als Träger wurden Polykationen mit Pyridinium- bzw. 1,2-Dimethylimidazoliumgruppen verwendet, …

The Use of Functionalized Zirconocenes as Precursors to Silica-Supported Zirconocene Olefin Polymerization Catalysts
… forming covalently immobilized metallocene catalysts. This dissertation concerns the synthesis of electrophile-functionalized zirconocene dihalide complexes and the use of functionalized zirconocene dihalides as precursors to silica-supported metallocene olefin polymerization catalysts. Our …
