AI Article Synopsis
- - Metallic titanium nanoparticles measuring 1.5 ± 0.4 nm in diameter are created using lithium naphthalenide to reduce titanium tetrachloride in tetrahydrofuran.
- - Advanced characterization techniques like HRTEM, FFT, optical spectra, and XANES verify the nanoparticles' chemical structure.
- - The titanium nanoparticles exhibit high reactivity, which allows them to directly transform into titanium carbide (TiC) while maintaining their size.
Article Abstract
Metallic titanium (Ti(0)) nanoparticles, 1.5 ± 0.4 nm in diameter, are obtained via lithium naphthalenide ([LiNaph])-driven reduction of TiCl4× 2THF in tetrahydrofuran (THF). HRTEM, fast Fourier transformation (FFT), optical spectra and X-ray absorption near edge structure (XANES) confirm their chemical composition. Besides their pyrophoric properties, their high reactivity is validated by direct transformation of Ti(0) into TiC maintaining the size.

The future of environmental monitoring, medical diagnostics, and industrial safety depends on developing room-temperature, long-term operable, stable, miniaturized, ultrahigh-performance sensors integrated into the Internet of Things (IoT). While noble metals and high-entropy alloys (HEAs) lead in addressing the limitations of conventional transition-metal dichalcogenides (TMDs) like MoS₂, they face challenges such as high-cost, limited availability, and fabrication complexity. To address this, multifunctional, cost-effective, humidity-insensitive novel phase Ti₀.

Herein, we report for the first time the use of ternary oxide nanoheterostructure photocatalysts derived from (Nb , Ti )CT MXene in the treatment of water. Three different compositions of binary MXenes, viz., (TiNb)CT , (TiNb)CT , and (TiNb)CT (with T = OH, F, and Cl), were used as single-source precursor to produce TiNbO -3:1, TiNbO -1:1, and TiNbO -1:3 by controlled-atmosphere thermal oxidation.

Magnetoelectric (ME) small-scale robotic devices attract great interest from the scientific community due to their unique properties for biomedical applications. Here, novel ME nano hetero-structures based on the biocompatible magnetostrictive MnFe O (MFO) and ferroelectric Ba Ca Zr Ti O (BCZT) are developed solely via the hydrothermal method for the first time. An increase in the temperature and duration of the hydrothermal synthesis results in increasing the size, improving the purity, and inducing morphology changes of MFO nanoparticles (NPs).

Nanoporosity is clearly beneficial for the performance of heterogeneous catalysts. Although exsolution is a modern method to design innovative catalysts, thus far it is predominantly studied for sintered matrices. A quantitative description of the exsolution of Ni nanoparticles from nanoporous perovskite oxides and their effective application in the biogas dry reforming is here presented.

The performance of catalysts used in after-treatment systems is the key factor for the removal of diesel soot, which is an important component of atmospheric fine particle emissions. Herein, three-dimensionally ordered macroporous-mesoporous TiSiO (3DOM-m TiSiO) and its supported MnO catalysts doped with different alkali/alkaline-earth metals (AMnO/3DOM-m TiSiO (A: Li, Na, K, Ru, Cs, Mg, Ca, Sr, Ba)) were prepared by mesoporous template (P123)-assisted colloidal crystal template (CCT) and incipient wetness impregnation methods, respectively. Physicochemical characterizations of the catalysts were performed using scanning electron microscopy, X-ray diffraction, N adsorption-desorption, H temperature-programmed reduction, O temperature-programmed desorption, NO temperature-programmed oxidation, and Raman spectroscopy techniques; then, we evaluated their catalytic performances for the removal of diesel soot particles.
