  - ELECTROCHIMICA ACTA - Year 2017

  Triphenylamine-based hydrazones were subjected to electropolymerization process that gave well conductive hydrazone based polymers. The first example of polyhydrazone formation during the electrochemical process was shown. The estimation of polymer structure was demonstrated using IR spectroelectrochemistry. The EPR spectroelectrochemistry allowed to explain why in some cases dimer couldn’t be formed. The results of electrochemical,...

  - ELECTROCHIMICA ACTA - Year 2015

  Acridone derivative have been synthesised and used as OLED (Organic Light Emitting Diode) emitters which were found to be electroactive. Electrochemical investigations showed a side reaction takes place inside an active layer which diminished the overall device efficiency. By using a dopant and host active layer architecture, the formation of the by product was removed. The by-product was identified as a σ-dimer formed inside an...

  - ANTI-CORROSION METHODS AND MATERIALS - Year 2012

  Celem pracy było uzyskanie informacji dotyczących zróżnicowania parametrów elektrycznych uzyskanych na podstawie zarejestrowanych chwilowych widm impedancyjnych w zakresie aktywacji i reaktywacji roztwarzania wysokostopowej stali austenitycznej AISI podczas postępującego procesu korozji międzykrystalicznej. Badania prowadzono z wykorzystaniem dynamicznej elektrochemicznej spektroskopii impedancyjnej (DEIS). Pomiary wykonywano ''on-line''...
