Abstract:

In order to improve the photocatalytic efficiency, the N doped anodic titania film for photocatalyst was synthesized by anodic oxidation of TiN layer in sulfuric electrolyte, and the photocatalytic properties of N doped TiO2layer were investigated. During the oxidation process of the TiN layer, nitrogen was doped into the anodic titania film due to the change of the titanium nitride layer to TiO2layer film. In the evaluation of dye degradation, N doped titania catalyst shows much higher efficiency than non-doped titania film.

Abstract:

Optical properties of titania thin films supported on silica plates and compounded with varying amounts of Co(II) from cobalt nitrate are reported. The ellipsometric characterization allows to model the spatial micro-structure of these thin film composites. The titania films were produced by the sol-gel method at room temperature and their thicknesses can be controlled by modifying the experimental conditions. The refractive index of the doped titania films was also determined by using ellipsometry.

Iridium serves as the active electrocatalyst in driving the hydrogen evolution reaction (HER), an important process in water-splitting technology for the production of green hydrogen.

Abstract:

Surface-Enhanced Raman Scattering (SERS) sensors are versatile biosensors for detecting very low concentrations of molecules. Their molecular and chemical sensitivity crucially depends on the tailoring of their nanostructure. These sensors rely on noble metal or oxide cluster layers, with their crystallinity and nanostructure carefully tuned to enable a maximum of plasmonic hot spots and enabling charge transfer. Typically, such sensors are in thin film geometry. In order to optimize their nanostructure and optical properties of the metal or oxide clusters, cellulose nanofibrils (CNFs) as temp

Abstract:

Photocatalytic hydrogen generation at the single nanoparticle level has the potential to reveal unprecedented insights into the fundamental mechanisms of hydrogen production. This research aims to understand the photoelectrochemical and photocatalytic properties of individual SrTiO3 nanoparticles, and how these correlate to the bulk behavior, addressing a critical gap in our understanding of nanoscale catalysis. While most single nanoparticle studies are conducted in vacuum environments, these conditions do not reflect the actual environment of H2 production from water splitting. To overcome t

AbstractLead lanthanum titanate ((Pb1−x/100Lax)Ti1−x/400O3, x=10, 20, 28) sol-gel thin films were prepared on SiO2/Si and glass substrates using lanthanum nitrate as a La precursor. The effect of the processing conditions was investigated and the optical properties of the films were measured to obtain good films for waveguide applications. The perovskite crystalline phase is achieved regardless of the heating condition but the slower heating creates better quality films. La content in the film does not effect on the refractive index and transparency of the film.

Also, to examine the possibility of oxygen contamination, we compared the infrared spectrum of the tholin film with that of a t

ABSTRACTAluminum nitride (AlN) films are being investigated for piezoelectric and high temperature applications, but the piezoelectric response is still much lower than that of more common piezoelectric materials such as lead zirconate titanate or zinc oxide.

These stack structures were created by depositing a thin, ∼50nm, metal layer in between thicker, ∼150-350nm, layers of the piezoelectric film. Platinum was chosen as the metal in

This sensitivity, along with a relative ease of manufacture, makes SAW devices ideally suited for many sensing applications including mass, pressure, temperature, and biosensors.

Strontium titanate [SrTiO3 (STO)], a perovskite oxide with an extremely high gate-tunable dielectric constant (ε) due to quantum paraelectric phases, is attracting considerable attention for yielding various physical phenomena when two-dimensional (2D) layers are integrated. Superconductivity is such a typical phenomenon. However, the influence of the STO substrates on enhancing transition temperatures (Tc) for (atomically) thin 2D flakes attached to them has been rarely investigated.
