Synthesis of Group IVB Metals Oxicarbides by Carboreduction Reactions

Materials Research, 2002
The metals of the group IV B (Ti, Zr, Hf) present a series of carbides and oxicarbides with scientific and technological interest. Many of these compounds belong to the subsystem "MO - MC" of the pseudoternary "MO - MN - MC" system (where M = Ti, Zr or ...

From Food Waste to Valorized Nanomaterials: Sustainable Green Synthesis and Biomedical Applications

ChemFoodChem, EarlyView.
Food waste‐derived biomolecules act as natural reducing and stabilizing agents for the green synthesis of functional NPs with applications in antimicrobial systems, food packaging, biomedical technologies, and environmental remediation. ABSTRACT Food waste is a global issue, with billions of tons discarded and unutilized annually, causing economic ...

On the Reaction Mechanism of Nitrate Radical and DMPO in Non‐aqueous Photocatalytic Media

Chemistry – A European Journal, EarlyView.
This work identifies 2‐oxo‐5,5‐dimethyl‐1‐pyrroline 1‐oxyl (DMPOX), formed via the selective oxidation of 5,5‐dimethyl‐1‐pyrroline N‐oxide (DMPO) by nitrate radicals (NO3•) in nonaqueous media, as a distinctive EPR fingerprint of NO3•. The DFT‐supported mechanism clarifies its formation pathway and highlights DMPOX detection as a robust tool for ...

The cytotoxic targets of anatase or rutile + anatase nanoparticles depend on the plant species

Biologia plantarum, 2017
The potential toxicity of nanoparticles (NPs) is under debate. Information about TiO2 NPs phytotoxicity is still limited partly due to the different TiO2 NP forms that may be found in the environment. The present work investigated the impact of different TiO2 NPs forms (rutile and anatase) on germination, growth, cell cycle profile, ploidy level, and ...

[Ti(py)4I2] as an Entry Point to Titanium(II) Chemistry via Titanium Metal Oxidation

Chemistry – A European Journal, EarlyView.
A strategically novel approach based on the oxidation of Ti metal enables access to Ti(II) chemistry. Controlled formation and complexation of Ti diiodide affords the Ti(II) complex [Ti(py)4I2], which serves as a convenient entry point to Ti(II) compounds.

Insight Into the Origins of N2O Byproduct on Confinement Structure TiO2/MnSm Catalyst Through Sulfation Pre‐Treatment for Low‐Temperature NH3‐SCR Reaction

EcoEnergy, EarlyView.
Sulfation of TiO2 with tubular architecture assembly nanosheets cooperated with Sm modification endowed the TiO2–SO42−/MnSm catalyst with excellent low‐temperature NH3‐SCR activity, high N2 selectivity, and well H2O‐resistance. It clarifies how the Sm modification and sulfation adjusts the distribution of acid sites and modulates the activation of NH3 ...
