Syntezy prowadzone były reakcji 2≡SiSH+ MnCl2 + 2Et3N = (≡SiS)2Mn + 2Et3N.HCl doprowadziły do otrzymania nowych kompleksów: [Mn{SSi(OBut)3}2(MeOH)4] (gdy jako rozpuszczalnik zastosowano MeOH) oraz [Mn{SSi(OBut)3}2(NCCH3)], gdy w badaniach posłużono się acetonitrylem.

  - ELECTROCHIMICA ACTA - Year 2018

  In this work we show the impact of applied potential on network vibrations and photoelectrochemical properties of a composite material containing hydrogenated titania nanotubes and poly (3,4-ethylenedioxythiophene) with iron hexacyanoferrate (H-TiO2/pEDOT:Fehcf) acting as a redox centre. For this purpose, Raman spectroscopy measurements under the working electrode (WE) polarization were carried out, allowing investigation of changes...

  - REACTIVE & FUNCTIONAL POLYMERS - Year 2018

  Poly(ε-caprolactone) and poly(3-hydroxybutyrate) (PCL/PHB) blends in two weight ratios (75/25 and 50/50) were reactively compatibilized in the presence of di-(2-tert-butyl-peroxyisopropyl)-benzene and dicumyl peroxide as free radical initiators. Rheological, mechanical, thermal properties and morphological features, as well as the chemical structure of PCL/PHB blends were investigated. It was found that regardless of PCL/PHB blend...

  The aim of this study was to estimate the structure of new polyurethanes with the potential to be used in medicine. Atactic poly[(R,S)-3-hydroxybutyrate], obtained via a ring-opening polymerization, and polycaprolactonediol or polyoxytetramethylenediol were used to built the soft segments. 4,4'-methylene dicyclohexyl diisocyanate and 1,4-butanediol were the components to form hard segments. Polyurethanes with low-molecular weight...

  Electrophoretic deposition (EPD) of chitosan/poly(4-vinylpyridine) (chit/P4VP) coatings on titanium substrates previously decorated with silver nanoparticles (AgNPs) was performed at different content of P4VP in the suspension and different voltage values. The results revealed that the composite coatings were formed, well-adjacent to the titanium substrate, of suitable roughness, hydrophilicity, and corrosion resistance. The voltage...

  Otrzymano nową fazę stacjonarną na bazie dibenzyloksy pochodnej kaliks[4]arenu w konformacji 1,3-naprzemianległej, chemicznie związaną z żelem krzemionkowym. Przeprowadzano badania selektywności i sprawności tej fazy w rozdzielaniu izomerów konstytucyjnych benzenu i pochodnych fenoli. Zaprezentowano wyniki badania wpływu pH fazy ruchomej oraz stężenia metanolu na zdolność rozdzielczą nowej fazy stacjonarnej.
