Conductivity and aging behavior of Sr(TiFe) O mixed conductor materials.

Perovskite materials play a significant role in oxygen sensors due to their fascinating electrical and ionic conductivities. The sol-gel technique was employed to prepare various compositions of B-site-deficient Fe-doped SrTiO (iron-doped strontium titanate) or Sr(TiFe) O , where = 0.01, 0.

Experimental and Theoretical Studies on Optical Properties of Tetra(Imidazole) of Palladium (II) Phthalocyanine.

In this work, the optical properties of tetra(imidazole) of palladium phthalocyanine (PdPc(Im)) in solution form and thin films on glass and fluorine-doped tin oxide (FTO) substrates were investigated via the thermal evaporation technique. The optical band gap was evaluated by ultraviolet-visible spectroscopy (UV-Vis). The energy band gap values were determined based on the Tauc graph.

Physical and Dielectric Properties of Ni-Doped InS Powders for Optical Windows in Thin Film Solar Cells.

This paper reports the effect of Nickel (Ni) on indium sulfide (InS) powder. This work presents a systematic study of the physical and dielectric properties of InSNi powders with 0, 2, 4, and 6 at.% of nickel.

Impedance Spectroscopy and Dielectric Relaxation of Imidazole-Substituted Palladium(II) Phthalocyanine (ImPdPc) for Organic Solar Cells.

In this study, we investigated the potential of palladium tetrakis (imidazole) phthalocyanine (PdPc(Imz)) for use as an organic semiconductor for improving the photovoltaic performance. In order to get more information about the prevailing model of the conduction mechanism (correlated barrier hopping (CBH)) for PdPc(Imz), electrical impedance measurements were performed at different temperatures and the obtained data were simulated by the Kohlraush Williams Watt (KWW) approach. Theoretical studies (density functional theory (DFT)) were performed and molecular electrostatic potential (MEP) maps were also extracted to understand the relationship between the molecular structures and the molecular electronic structure of PdPc(Imz) and its semiconductor properties.

Synthesis of Electrospun TiO Nanofibers and Characterization of Their Antibacterial and Antibiofilm Potential against Gram-Positive and Gram-Negative Bacteria.

Recently, titanium dioxide (TiO) nanomaterials have gained increased attention because of their cost-effective, safe, stable, non-toxic, non-carcinogenic, photocatalytic, bactericidal, biomedical, industrial and waste-water treatment applications. The aim of the present work is the synthesis of electrospun TiO nanofibers (NFs) in the presence of different amounts of air-argon mixtures using sol-gel and electrospinning approaches. The physicochemical properties of the synthesized NFs were examined by scanning and transmission electron microscopies (SEM and TEM) coupled with energy-dispersive X-ray spectroscopy (EDX), ultraviolet-visible spectroscopy and thermogravimetric analyzer (TGA).
