Organoferrate als Intermediate in Eisen-Katalysierten Kreuzkupplungsreaktionen
(2019-05-24)In the context of this work a combination of ESI mass spectrometry, mößbauer spectroscopy and electrical conductometry was used to identify and characterize a large number of organoferrates. These anionic species, which ... -
Der Einfluss von Defekten auf das Schaltverhalten ferroelektrisch modulierter Substanzen
(2016-04-26)The influence of defects on the phase transition behavior of A2BX4-compounds was studied by diffraction methods, impedance spectroscopy and atomic force microscopy. It was found that chemical point defects have a strong ... -
Strukturaufkälrung von Natrium-Solvens-Clustern durch IR-anregungsmodulierte Photoionisatiosnspektroskopie
(2012-10-09)In this work the method of IR-excitation modulated photoionisation mass spectroscopy is introduced. As a preparation, it is shown in a photoionization study that at least two classes of isomers exist for larger sodium doped ... -
Partikelbildung bei der Alkenozonolyse und ihre Kopplung an die Radikalchemie
(2012-08-21)Global warming is one of the most crucial and challenging problems in recent times. However, many aspects of this field are highly fraught with uncertainty, including the new particle formation in the atmosphere. Aside ... -
Fluorfunktionelle 1,3-Diaza-2-sila-cyclopentene -Synthese, Reaktionen und Kristallstrukturen
(2009-02-09)The synthesis of new, unknown aluminium, gallium and amino-substituted diaza-silacyclopentenes-compounds is the point of interests of this work. Lithiumsalts react like iminosilenes with elment-compounds of the 13. main-group. ... -
Lithiumamide, -hydrazonide und -ketazide als Bausteine acyclischer, cyclischer und spirocyclischer Bor-, Phosphor- und Siliciumverbindungen sowie monomerer und dimerer Amino-imino-borene
(2009-02-09)Flurorosilylhydrazones are obtained from the reaction of lithiated hydrazones with fluorosilanes. On subsequent reaction with tert-butyllithium, cyclization takes place, to give ... -
Oberflächenchemie an Silicium-Nanopartikeln
(2009-02-05)Two nanocrystalline silicon powders from industrial production that differ in their primary particle size (50-300 nm and 5-10 nm), were used for surface modifications on the nanometer scale. ...
