New reaction of dithiophosphoric acids with O-thioacylhydroxylamines. Nucleophilic substitution or single electron transfer process?
PublicationUdowodniono, że dipodstawione lub sterycznie przeszkodzone hydroksyloaminy reagują z przestrzennie rozbudowanymi S-tioacyloditiofosforanami dając odpowiednie O-tioacylohydroksyloaminy. Dalsza reakcja O-tioacylohydroksyloaminy z kwasem ditiofosforowym prowadzi do powstania disiarczku acylowo tiofosfo-rylowego oraz soli amoniowej kwasu ditiofosforowego. Wpływ pułapek rodnikowych na wydajność tej reakcji świadczy dobitnie, że w procesie...

A measurement system for nonlinear surface spectroscopy with an atomic force microscope during corrosion process monitoring
PublicationIn addition to traditional imaging the surface, atomic force microscopy (AFM) enables wide variety of additional measurements. One of them is higher harmonic imaging. In tapping mode the nonlinear contact between tip and specimen results in higher frequency vibrations. More information available from the higher harmonics analysis proves to be helpful for more detailed imaging. Such visualization is espe-cially useful for heterogeneous...
