Improved Process for Separating TiO₂ from an Oxalic-Acid Hydrothermal Leachate of Vanadium Slag

Metals, 2022
In the present study, a process of separating high-quality TiO2 from an oxalic-acid leachate of vanadium slag was proposed. It consists of two steps; oxalic acid was firstly recovered from the leachate by the cooling-crystallization method, and ...

The interplay between dopants and oxygen vacancies in the magnetism of V-doped TiO2

, 2011
Density functional theory calculations indicate that the incorporation of V into Ti lattice positions of rutile TiO2 leads to magnetic V4+ species, but the extension and sign of the coupling between dopant moments confirm that ferromagnetic order cannot ...

Dual‐Functional Additive Regulating Zn2+ Solvation Structure and (002) Plane‐Oriented Deposition for Dendrite‐Free Zn Anodes

Advanced Functional Materials, EarlyView.
Sulfosalicylic acid (SSA) is introduced as a bifunctional additive for Aqueous zinc‐ion batteries. SSA reconstructs the solvation structure of Zn2+ through the synergistic effects of its multiple functional groups, suppressing side reactions while selectively promoting Zn (002) deposition to prevent dendrite formation.

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.
