Femtosecond quantum control and adaptive polarization pulse shaping
… und insbesondere Moleküle, die eine chemische Reaktion durchlaufen, sind durch speziell geformte, Femtosekunden-Laserimpulse kontrolliert worden. Diese Methode erlaubt es, nicht nur das Quantensystem zu beobachten, sondern einen Schritt weiterzugehen und aktive Kontrolle über …

Zur Aromatenfunktionalisierung in Gegenwart ionischer Flüssigkeiten
The goal of this dissertation was to identify ionic liquids with a catalytic effect on the test reactions (aromatic Halex reaction and Friedel-Crafts-Acylation). Beside that, ionic liquids have been synthesized in pure form and characterised by NMR, cyclovoltammetrie, UV-vis-spectroscopy and …

Untersuchungen zur Hochtemperaturchemie quecksilberfreier Metallhalogenid-Entladungslampen mit keramischem Brenner
The development of mercury-free metal halide lamps requires a modification of the burner vessel design and of the metal halide filling, compared to mercury-containing lamp types. Metal halides as NaI, TlI, DyI3 are added to discharge lamps in order to achieve a line-rich emission spectrum, …

Quasistationarität und fast-invariante Mengen gewöhnlicher Differentialgleichungen
The objective of the present paper is to analyse the concept of quasi-stationarity, which is motivated from bio-chemistry, and to investigate it from a matematical perspective. In Chapter 1 the concept of quasi-stationarity is presented in the context of chemical reactions. Examples, particularly …

Computergestützte Analyse des reaktiven Strömungsmischens in T-Mikroreaktoren
Due to the large area-to-volume ratio micro-reactors exhibit an effective mass and heat transfer. They also show immediately responses to changes in operating conditions. Therefore micro-reactors are suitable for the analysis of fast exothermic chemical reactions. The multiscale analysis of laminar …

Mathematical approaches to modelling and controlling blood thrombin formation
Chapter 1 is a brief description of the blood coagulation system. Besides making an excursion through the nomenclature and the principal properties, we are confronted with the pertinence of questions that are in nowadays object of discussion among the scientific community investigating the process …
