A method for preparing and observing clay platelets for size and shape analysis using scanning electron microscopy (SEM) was developed. Samples of the clay platelets were prepared by polyelectrolyte-assisted adsorption onto a pyrolytic graphite surface. Th ...
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 distance control system for low-temperature scanning near-field optical microscopy, based on quartz tuning fork as shear force sensor. By means of a particular tuning fork optical fiber configuration, the sensor is electrically dithered by a ...
A newly designed thin-layer STM (TLSTM) technique is presented based on a microfabricated probe combining an electrolytic STM probe with an annular iridium oxide microelectrode operating as a potential-controlled generator or scavenger of H+. This TLSTM co ...
During their production, single-walled carbon nanotubes form bundles. Owing to the weak van der Waals interaction that holds them together in the bundle, the tubes can easily slide on each other, resulting in a shear modulus comparable to that of graphite. ...
Secondary fly ash, resulting from thermal treatment processes, leads to a highly concd. chloride soln. with Cu, Pb, Cd and Zn as main heavy metals when dissolved in water. The selective electrodeposition of these heavy metals was studied. The goal was to r ...
Diamond films with different levels of doping have been the subject of applications and fundamental research in electrochemistry, opening up a new branch known as the electrochemistry of diamond. The electrochemical properties of diamond mostly depend on t ...
PLZT 4/65/35 thin films were prepared by the acetic acid based sol-gel route. The choice of lanthanum precursor, i.e., acetate or nitrate, influences the functional group content of formamide modified sols and the microstructure of the thin films. The lant ...
Electrode stability, interdiffusion, phase purity and deviation from stoichiometry at the PZT-electrode interface are key issues in PZT thin film integration. This article highlights the use of transmission electron imaging combined with energy dispersive ...
The catalytic activity of IrO2 catalyst used as an electrode on a YSZ solid electrolyte cell for the gas phase combustion of ethylene can be increased by electrochem. pre-treatment. Thus, the polarization of the IrO2 electrode for 90 min at 300 mA, relativ ...
