Electron Dynamics in Anatase TiO

, 2019
The optical bandgap of anatase TiO2 nanoparticles is dominated by bulk absorption bands in the deep-ultraviolet due to strongly bound excitons. These spectral features can be utilized as a sensitive probe of carrier and lattice dynamics inside the TiO2 ...

Integrated Solvent‐Catalyst‐Dopant Strategy via Acidic DES for Synthesizing Lignin‐Derived Carbon Dots With High‐Quantum Yield to Achieve Efficient Photocatalytic Degradation of Tetracycline

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A deep eutectic solvent (ChCl/pTSA) platform enables integrated solvent, catalyst, and dopant functions, producing sulfur‐doped carbon quantum dots with a high sp2‐C content (82.8%) and a quantum yield of 56.9%. When combined with TiO2, the CQDs form TiOC and TiOS interfacial bridges, achieving 97.3% tetracycline photodegradation with excellent ...

Foil-based TiO₂/gel electrolyte/Ni_1-xO electrochromic device made of electrochromic pigment coatings

Acta Chimica Slovenica, 2014
Thin electrochromic coatings were obtained by co-grinding the mTiA particle aggregates (300 nm in size) with open-corner heptaisobutyl trisilanol POSS (T8 IB7 (OH)3 POSS) acting as dispersant. After the addition of titanium tetraisopropoxide (3-5 %) the

Preparation and Characterization of the Highly Regular Nitrogen Doped Anatase TiO2 Nanotube

, 2013
Nitrogen-doped TiO2 nanotabes (N-TNTs) were fabricated on the titanium foil by anodic oxidation and followed by annealing at NH3 environment. Highly ordered nanotubes, roughly 150 nm in the diameter and 20 mu m in the length, were synthesized on the ...

Engineering a Multifunctional g‐C3N4/TiO2 Active Packaging Film With Enhanced Barrier and Photocatalytic Properties for Postharvest Preservation of Plum Fruit

Future Postharvest and Food, EarlyView.
The engineered g‐C3N4/TiO2@PVA active packaging film efficiently degrades exogenous ethylene under LED irradiation, effectively suppressing the endogenous ripening pathway of “Wushan” plums. Combined with enhanced barrier properties, this multifunctional film significantly delays the climacteric respiration peak and extends fruit shelf life.

Hydrothermal Synthesis of Anatase-type ScTiNb0_6 Nanoparticles [PDF]

, 2009
A single phase of anatase with composition of ScTiNbO6 was directly synthesized as nano-sized particles from precursor solution mixtures of Sc(NO3)3，TiOSO4，and NbCl5 under weakly basic hydrothermal condition at 180℃ for 5 h in the presence of urea.

Exploring the Chemical Complexity and Toxicological Behaviour of Semi‐permanent Make‐Up Pigments: A Systematic Review

Journal of Applied Toxicology, EarlyView.
ABSTRACT Semi‐permanent make‐up (SPMU), or micropigmentation, involves implanting pigments into the dermal layer of the skin for cosmetic enhancement. Unlike topical cosmetics, which are rapidly cleared from the body, SPMU pigments persist in living tissues, raising unique toxicological considerations.

On‐site pilot‐scale advanced oxidation pretreatment of hospital wastewater: assessment of pharmaceuticals, pathogens, antibiotic resistance genes and acute ecotoxicity

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Hospital premises generate wastewater containing a wide spectrum of contaminants, such as pharmaceutically active compounds (PhACs), antibiotic resistance genes (ARGs) and pathogenic microorganisms, whilst plenty of them are classified under the antibiotic resistant bacteria (ΑRΒ) category.
