Abstract: Due to their stability and reversible redox activity, PEDOT-based copolymers are extensively investigated for electrochromic applications. For that reason, different modifications have been tried on the structure of PEDOT polymer in order to control both electrochemical and optical characteristics. Copolymerization of EDOT with carbazole monomer is one of the used modifications to alter and improve electrochromic properties. Despite these modifications, the electrochemical stability of the PEDOT-based copolymers is still a debate. To this end, a star-like shape of poly (EDOT-co-OctaCBz-POSS) copolymer was electrochemically synthesized by incorporating a carbazole-substituted polyhedral oligomeric silsesquioxane.......

Abstract: Treatment of infectious diseases has become more challenging and has had a major influence on treatment rates due to the advent of new transmissible diseases and the rise in resistance of pathogens to available antibiotics. The use of nanoparticles as an antibiotic replacement has also gained attention due to the multidrug resistance of antibiotics to bacterial infections. This study investigated the synthesis and characterization of iron doped copper oxide nanoparticles (Fe-CuO Nps). Different characterization techniques which include X-ray diffraction (XRD), Scanning Electron Microscopy (SEM)/Energy Dispersive X-ray Spectroscopy.......

ABSTRACT: A novel pyrazole derivative, 3-(1,3-bis(4-bromophenyl)-1H-pyrazol-4-yl)-2-(4-bromophenyl) acrylonitrile (BPPBPA), has been successfully synthesized and investigated as a highly selective and sensitive chemosensor for the detection of Cu (II) ions. Both absorption and emission spectroscopic studies clearly demonstrate the sensing capabilities of BPPBPA. Upon interaction with Cu (II) ions, the absorption spectrum exhibited a noticeable red-shift......
