Recent progress concerning the development of counter electrode material (CE) from the dye-sensitized solar cells (DSSCs) and the electrode material (EM) within supercapacitors is reviewed. From composites based on carbon nanotubes (CNTs) and conducting polymers (CPs) to their biggest competitor, namely composites based on graphene or graphene derivate (GD) and CPs, there are many methods of synthesis that influence the morphology and the functionalization inside the composite, making them valuable candidates for EM both inside DSSCs and in supercapacitors devices. From the combination of CPs with carbon-based materials, such as CNT and graphene or GD, the perfect network is created, and so the charge transfer takes place faster and more easily.

The free-standing TPU-TiO NW films were prepared by a wet chemical method accompanied by a thermal treatment at 100 °C for 1 h, followed by air-drying for 2 h. X-ray diffraction (XRD) studies indicated that the starting commercial TiO NW sample contains TiO tetragonal anatase (A), cubic TiO (C), and orthorhombic TiO (OR), as well as monoclinic HTiO (M).

Raman scattering and FTIR spectroscopy studies indicate that the interaction of BP with PTA leads to the elimination of the PO layer onto the surface of the BP sheets. In the case of the chemical interaction of BP with DPA, the reaction product corresponds to DPA chemically functionalized BP sheets having an imino-phosphorane (IP) structure.

To develop new anti-melanoma biocompatible species, the series of complexes Cu(N-N)(bzac)(X)⋅nHO (N-N: 1,10-phenanthroline/2,2'-bipyridine, Hbzac: 1-phenyl-1,3-butanedione, X: NO/ClO, and = 0, 1) was studied. Single-crystal X-ray diffraction revealed a mononuclear structure for all complexes.
