OPTICAL PROPERTIES OF ANODIC TITANIA AND IT'S APPLICATION IN MAXILLOFACIAL SURGERY

Доклады Белорусского государственного университета информатики и радиоэлектроники, 2019
Studying of anodic titania formation has showen that anodization forming factor at low anodic voltages is 3,3 nm/V, while at high anodic voltages it’s value decreases till 1,5 nm/V. The investigation of optical properties of anodic titania has showed the

Decolorization of Ponceau Red 4R with TiO2/ZnO: Effect of calcination temperature and Fe addition

Environmental Progress &Sustainable Energy, EarlyView.
Abstract The photocatalytic degradation of azo dyes using semiconductor oxides has emerged as a promising strategy for wastewater remediation. In this study, pure, mixed, and Fe‐doped oxide catalysts based on Zinc Oxide and Titanium Dioxide were synthesized and evaluated for the degradation of Ponceau 4R under ultraviolet irradiation.

Engineering Photonic Pigments From Titania–Block Copolymer Composites

Macromolecular Rapid Communications, EarlyView.
Ligand‐functionalized TiO2 nanoparticles selectively partition into P2VP‐rich lamellae of onion‐like PS‐b‐P2VP microspheres, increasing refractive index contrast while preserving concentric order through controlled self‐assembly. The resulting dry photonic pigments display defined Bragg reflections and angle‐robust structural color.

Mixed TiO2–SiO2 thin coatings for selective adsorption and sunlight‐powered photodegradation of cationic pollutants

Responsive Materials, EarlyView.
Environmental pollution and water scarcity demand innovative purification methods. This study presents a sol‐gel approach to fabricate mixed silica–titania thin films joining photocatalytic activity with selective sorption capability. The films exhibit higher surface area, enhanced degradation of cationic and improved performance over bare titania ...

Electrocatalytically Amplified Immunosensing Enabled by Titanium Oxynitride‐Supported Ru Nanodots on Graphene Oxide Hybrid Architecture

Small, EarlyView.
A synergistic effect among the electrocatalytic Ru/TiON‐GO nanocomposite, biorecognition elements, and the [Fe(CN)6]3−/4− redox probe for highly sensitive and selective impedimetric detection of PSA protein in human serum was demonstrated. The immunosensor exhibited a limit of detection of only 0.06 ng mL−1 PSA protein, underscoring the importance and ...

Hierarchical Peptide Functionalized Titania Nanotubes: Improving Stability, Promoting Osteogenesis, and Reducing Infection Risk

Small, EarlyView.
The study demonstrates a dual‐level modification of titania nanotube surfaces through the covalent grafting of Fmoc‐FF dipeptides, followed by a secondary self‐assembled layer of FF dipeptide. This hierarchical strategy significantly enhances coating density and structural integrity without compromising the nano‐topographical and biochemical cues ...
