Article Abstract
Vanadium selenium has gained attention as a potential anode for sodium-ion batteries (SIBs) due to the tunable crystal structure, effective channels for Na diffusion, and high theoretical specific capacity. However, the pursuit of vanadium selenium remains an enormous challenge. Herein, we demonstrated that VSe nanosheets could be fabricated facilely and efficiently a one-pot synthesis method with the careful selection of the solvent/surfactant. The VSe anode have demonstrated excellent electrochemical performance for SIBs. An intercalation and conversion mechanism of Na-storage in VSe were clarified by X-ray diffraction. This work develops an effective strategy to fabricate transition metal chalcogenides for high-performance sodium storage.

Atomic-scale elucidation of phase transition pathways in two-dimensional (2D) materials is practically necessary for achieving desired architectures in next-generation devices, yet it remains hindered by insufficient understanding of defect-mediated kinetics. Here, we study the behavior of Se defects in mediating phase transitions in single-layer (SL) VSe grown on Au(111), achieved through controlled thermal annealing and selenium (Se) replenishment. Using scanning tunneling microscopy (STM) and angle-resolved photoemission spectroscopy (ARPES), we find that the initial SL VSe is a 1T phase featuring a substrate-induced moiré superstructure and that several annealing stages lead to two defective, Se-poor phases with an increased in-plane lattice constant.

Nature chose selenium as the antioxidant element center in proteins, permitting the reversible conversion of organic bioenzymes between oxidized and selenized forms. Despite the importance of such antielectronegativity reversibility, it has not yet been demonstrated in inorganic selenides. We report an unexpected example showing that oxy-substituted sites in metal selenides can be restored to selenized forms reversibly by mild electrochemical manipulation in a copper aqueous solution.

Wetlands play an important role in biogeochemical cycles, as their hydrological and edaphic properties drive chemical reactions that facilitate the storage or transfer of various elements. Some herbaceous wetlands are ecosystems dominated by grass-like communities, sedges and rushes, and the information available at international level reveals they are poorly studied ecosystems in terms of elemental analysis. This research seeks to contribute to the understanding of herbaceous wetlands producing an inventory of essential and non-essential elements, the latter expected to be increased from the direct interaction of the wetland with a road.

Alzheimer's disease (AD) is a typical neurodegenerative disorder primarily characterized by the deposition of β-amyloid (Aβ) plaques and the hyperphosphorylation of tau protein, leading to the formation of neurofibrillary tangles (NFTs). These pathological changes are closely associated with the imbalance of trace element homeostasis. Trace elements are extensively involved in fundamental physiological processes, including DNA synthesis, protein synthesis, energy metabolism, and enzymatic reactions, all of which are essential for cognitive function and brain development.
