Recent progress concerning the development of counter electrode material (CE) from dye-sensitized solar cells (DSSCs) and (EM) within supercapacitors is reviewed. From composites based on carbon nanotubes (CNTs) conducting polymers (CPs) to their biggest competitor, namely graphene or derivate (GD) CPs, there are many methods synthesis that influence morphology functionalization inside composite, making them valuable candidates for EM both DSSCs in devices. combination CPs with carbon-based...
In this work, three methods for the synthesis of composites based on poly(ortho-toluidine) (POT) and WS2 are reported: (a) solid-state interaction (SSI) POT with nanoparticles (NPs); (b) in situ chemical polymerization (ICP) ortho-toluidine (OT); (c) electrochemical (ECP) OT. The preparation sheets was performed by ball milling NPs followed ultrasonication solvent N,N’-dimethyl formamide. During POT/WS2 SSI ICP, an additional exfoliation reported. we demonstrated following: ICP method leads...
This article’s objective is the synthesis of new composites based on thermoplastic polyurethane (TPU) and TiO2 nanowires (NWs) as free-standing films, highlighting their structural optical properties. The TPU–TiO2 NW films were prepared by a wet chemical method accompanied thermal treatment at 100 °C for 1 h, followed air-drying 2 h. X-ray diffraction (XRD) studies indicated that starting commercial sample contains tetragonal anatase (A), cubic Ti0.91O (C), orthorhombic Ti2O3 (OR), well...
Melanoma is a skin cancer characterized by rapid growth and spread for which current therapies produce both resistance increased risk of infection. To develop new anti-melanoma biocompatible species, the series complexes Cu(N-N)(bzac)(X)⋅nH2O (N-N: 1,10-phenanthroline/2,2'-bipyridine, Hbzac: 1-phenyl-1,3-butanedione, X: NO3/ClO4, n = 0, 1) was studied. Single-crystal X-ray diffraction revealed mononuclear structure all complexes. The ability to scavenge or trap reactive oxygen species such...
In this work, new information concerning the optical properties of black phosphorus (BP) sheets chemically/electrochemically functionalized with diphenyl amine (DPA) and its macromolecular compound (poly(diphenylamine) (PDPA)) in absence/presence phosphotungstic acid (PTA) is reported. Raman scattering FTIR spectroscopy studies indicate that interaction BP PTA leads to elimination PxOy layer onto surface sheets. case chemical DPA, reaction product corresponds DPA chemically having an...
