Medical implants delivering drugs are used to ensure efficient medication at body sites, at which the conventional administration of drugs is insufficient. The application of drug-delivery coatings is a beneficial concept for implants exposed to mechanical ...
This thesis analyzes the properties of heavily doped nanocrystalline titanium dioxide. Thin films were deposited by magnetron sputtering with either water vapor as reactive gas or a periodically interrupted oxygen supply. The samples were at the same time ...
Two series of titania-based photocatalysts were prepared by the sputtering method, in pure Ar atmosphere at a pressure of 0.5 Pa using a vanadium target source in a direct dc mode with a discharge of 300 V. The time of deposition was varied between 1 and 1 ...
Two new innovative findings presented in this study are: (a) TiO2-cotton fabrics obtained by pretreatment with UVC-light (185nm) at atmospheric pressure introduced functionalities into the cotton surface enabling the chelation/binding of TiO2. This was pos ...
Titanium oxide (Ti(O)) xerogel films functionalized by protoporphyrin IX (PPIX) and ferrocene carboxylic acid (FCA) were deposited on indium tin oxide (ITO) electrodes following a sol–gel synthesis. PPIX and FCA were first complexed to titanium oxide precu ...
A review. Fluorine remains an insiders' tip in the life sciences as it enables the fine-tuning of biol. properties. However, the synthesis of fluorine-substituted target compds. is not always trivial. Virtually any fluorine atom attached to an org. backbon ...
Heterogeneous photocatalysis over TiO2 using the sunlight seems to be a promising technology for waste-water treatment and drinking water production. However, the overall efficiency of TiO2 under natural sunlight is limited to the UV-driven activity (λ < 4 ...
Abatement of trichloroethylene (TCE, 250 ppm in air) was studied in a novel nonthermal plasma (NTP) dielectric barrier discharge reactor with an inner electrode made of sintered metal fibers (SMF). The SMF electrodes modified with TiO2 and MnO2 were observ ...
Starting from six industrially available fluorinated pyridines, an expedient access to all three tetrafluoropyridines, all six trifluoropyridines, and the five non-com. difluoropyridines was developed. The methods employed for the selective removal of fluo ...
Small nanosized clusters of Co3O4 coated on PTFE (polytetrafluoroethylene) flexible film is reported as a novel supported photocatalyst effective in the fast discoloration of the azo-dye Orange II under simulated solar radiation in the presence of oxone (2 ...
