In this thesis, the synthesis and characterization of V2O5-nanostructures, as well as the gas sensing properties of V2O5-nanofibers and carbon nanotubes have been investigated. Various modifications of the nanowires have been successfully employed in order ...
We report on a study of pentacene thin-films grown by high vacuum deposition on silicon dioxide, using atomic force microscopy (AFM) and transmission electron microscopy (TEM). The nucleation density of pentacene islands on SiO2is found to rise ...
The methods for treating experimental data in the isomorphous replacement and anomalous scattering methods of macromolecular phase determination have undergone considerable evolution since their inception 50 years ago. The successive formulations used are ...
The issue of protein dynamics and its implications in the biological function of proteins are arousing greater and greater interest in molecular biology. In cryo-electron tomography experiments one takes several snapshots of a given biological macromolecul ...
Two mutations in the alpha-synuclein gene (A30P and A53T) have been linked to autosomal dominant early-onset Parkinson's disease (PD). Both mutations promote the formation of transient protofibrils (prefibrillar oligomers), suggesting that protofibrils are ...
The rotor stoichiometry of F-ATPases has been revealed by the combined approaches of X-ray diffraction (XRD), electron crystallography, and atomic force microscopy (AFM). XRD showed the rotor from the yeast mitochondrial F-ATPase to contain 10 subunits. AF ...
A dense post-rutile titanium dioxide (TiO2) phase was discovered in shocked garnet gneisses from the Ries crater by reflected-light microscopy, laser rnicroRaman spectroscopy and micro-beam X-ray diffraction. The Raman spectrum consists of nine bands at wa ...
Calcium phosphate precipitation obtained from aqueous solutions at room and body temperatures and pH 5.5-7.5 were investigated by high-resolution transmission electron microscopy (HRTEM), transmission electron diffraction, scanning electron microscopy (SEM ...
Electron crystallography and atomic force microscopy allow the study of two-dimensional membrane protein crystals. While electron crystallography provides atomic scale three-dimensional density maps, atomic force microscopy gives insight into the surface s ...
Structure and morphology of solid particles in precipitation from aqueous solutions correlate with formation (solution) conditions and thus reflect the growth mechanism. Calcium phosphate precipitation obtained from dilute aqueous solutions at room and bod ...
