Summary: In this study, indium oxide nanostructured films were synthesized using hydrogen assisted atmospheric pressure chemical vapor deposition technique at different deposition temperatures. The films' surface morphology, crystallinity, and optical properties were characterized, and their photoelectrochemical (PEC) activity was investigated. The sample grown at 950 degrees C exhibited optimal PEC performance, with high photocurrent density, incident photon to current conversion efficiency, and applied bias to photon conversion efficiency. The superior PEC performance of the sample was attributed to the film composition, crystallinity, bandgap reduction, flat band potential, and charge carrier density.

Summary: ZnO-based anodes were studied for the photoelectrochemical regeneration of NAD(+), with different morphologies of ZnO showing varying influences on the detection of NADH. The photocatalytic activity of ZnO decreased with increasing concentrations of NAD(+), due to absorption of ultraviolet irradiation by the coenzyme. The flower-like film showed a higher electrochemical surface area and led to a significant increase in NAD(+) regeneration compared to both electrochemical oxidation and the only photochemical reaction. Tests with formate dehydrogenase demonstrated that 94% of the regenerated NAD(+) remained enzymatically active.

Summary: By manipulating the morphology of MoS2 nanostructures on graphene, the photoelectrochemical performance can be significantly improved. The quality of the heterojunction between graphene and vertically aligned few-layer MoS2 nanosheets is enhanced at low temperatures, leading to better charge transfer properties. Vertically aligned nanosheets provide highly conductive edges, serving as an efficient pathway for photo-generated carriers and achieving optimal PEC performance when controlled within the carrier diffusion length.

Summary: This study reports on the synthesis, optoelectronic and electrochemical properties, aqueous supramolecular polymerization, and conductivity of polycyclic aromatic dicarboximide amphiphiles. The introduction of heterocycles, such as thiophene, pyridine or pyrrole rings, in the chemical structure of the model perylene monoimide amphiphile led to supramolecular polymerization in water. The presence of sulfur atoms in the thiophene-containing monomer resulted in crystalline nanoribbons with significantly higher electrical conductivity.
