Abstract:

Nanostructured hematite thin films are doped with zirconium successfully and also modified by introducing CNT using sol-gel method for their implementation as photo-electrode in photo-electrochemical (PEC) cell for hydrogen generation. XRD, UV-visible spectroscopy and PEC study techniques are used to characterize the thin films. The PEC responses of thin films are improved by introducing carbon nanotubes (CNT).

Nanostructured Zr-Pd Metallic Glass Thin Film for Biochemical Applications

Zr-Pd metallic glassy thin films with a hierarchical nano-scale structure, produced by magnetron sputtering of the Zr and Pd powder mixture, demonstrate a unique combination of physical and biochemical properties. Thermal stability of the nano-structured glassy samples, their resistance to oxidation in dry air and phase transformation behavior are discussed in the present work. These binary all...

Atomic layer deposition and properties of ZrO2/Fe2O3 thin films

Thin solid films consisting of ZrO2 and Fe2O3 were grown by atomic layer deposition (ALD) at 400 °C. Metastable phases of ZrO2 were stabilized by Fe2O3 doping. The number of alternating ZrO2 and Fe2O3 deposition cycles were varied in order to achieve films with different cation ratios. The influence of annealing on the composition and structure of the thin films was investigated. Additionally, ...

Formation and structure of V-Zr amorphous alloy thin films

Although the equilibrium phase diagram predicts that alloys in the central part of the V-Zr system should consist of V2Zr Laves phase with partial segregation of one element, it is known that under non-equilibrium conditions these materials can form amorphous structures. Here we examine the structures and stabilities of thin film V-Zr alloys deposited at room temperature by magnetron sputtering...

Electrode dependence of hydrogen-induced degradation in ferroelectric Pb(Zr,Ti)O3 and SrBi2Ta2O9 thin films

Forming gas annealing causes changes in the remanent polarization (Pr), coercive field (Ec), and leakage current ~I! in both PZT @Pb~Zr,Ti!O3# and SBT (SrBi2Ta2O9) samples with a variety of top electrode materials ~Pt, Au, Ag, Cu, Ni, and In2O3!, and the degree of degradation depends strongly on the top electrode material. These results may be explained by a model that is based on the catalytic...

Nanostructured α-Fe2O3 platform for the electrochemical sensing of folic acid.

α-Fe(2)O(3) nanofibers are synthesized by a simple and efficient electrospinning method and the selective determination of folic acid (FA) is demonstrated in the presence of an important physiological interferent, ascorbic acid (AA), using the α-Fe(2)O(3) nanofiber modified glassy carbon (GC) electrode at physiological pH. Bare GC electrode fails to determine the concentration of FA in the pres...
