Atmospheric trace gases and aerosols and climate interact in many ways. A quantitative assessment of the influence of trace gases and aerosols on climate can only be achieved if the interactions and feedbacks among these three major components are accounte ...
Both first-principles molecular dynamics and theoretical X-ray absorption spectroscopy have been used to investigate the aqueous solvation of cations in 0.5 M MgCl(2), CaCl(2), and NaCl solutions. We focus here on the species-specific effects that Mg(2+), ...
Trace metal speciation in seawater from the Bulgarian Black Sea coast was studied in situ by hollow fiber permeation liquid membrane (HF-PLM) and by diffusion gradients in thin-film gels (DGT). The concentrations of Cd, Cu, Ni, and Pb determined by HF-PLM ...
The new tris-carbene ligand [TIMEt-Bu] has been synthesized and fully characterized. Reaction of the free carbene with copper(I) salt provided an unprecedented dinuclear Cu(I)-Cu(I) complex, in which the cuprous ion is coordinated in a trigonal planar liga ...
Superparamagnetic iron oxide nanoparticles (SPIONs) were coated with polyethylenimine. Here, we briefly describe the synthesis as well as DNA:PEI:SPION complexes and the characterization of the compounds according to their particle size, zeta-potential, mo ...
The first part of this study consists in the investigation of the evaporation and the condensation rate of H2O in the presence of different types of ice in a low pressure flow reactor. The second part of the present work reports the study of chlorine activ ...
A model showing the importance of the parameters characterizing ion transport through geometrically defined nanoslits filled with electrolyte is presented. A conductance plateau sin log-log scaled at low salt concentrations in the nanometer-sized apertures ...
A description of ion transport through geometrically defined nanoslits is presented. It is characterized by the effective surface charge density and was obtained by impedance spectroscopy measurements of electrolytes with different physico-chemical propert ...
In this work the development of a low-temperature scanning probe microscope and the investigation of thin insulating films at the atomic limit is presented. The scanning probe microscope has been designed in a modular way to provide large flexibility for t ...
This thesis presents the different steps in the development of a multiple diagnostic experimental setup and the results concerning the kinetics of condensation and evaporation of water over pure ice, as well as ice films doped with a known amount of atmosp ...
