Abstract The potential applications of high‐power sodium‐ion batteries are numerous, including use in distributed energy storage power plants and electric vehicles. In order to develop anode materials with fast reaction kinetics high reversibility, the deep eutectic supramolecular polymers electrode is pioneered. LA‐DESP situ polymerized on Ti 3 C 2 T x MXene surface, resulting that exhibit rapid high‐capacity retention. polymer network constructs channels for high‐speed transport ions electrons, also provides more Na + pseudocapacitance sites. addition, superior mechanical properties help protect structure from damage during cycling, ultrastable storage. hopping migration mechanism through polymer‐constructed ion proposed. As SIBs half‐cells, it exhibits remarkable cycling performance 114.4 mAh g −1 a capacity loss only 5.1% at 1000 mA after 1500 cycles. This study opens new way rationally design promotes application electrodes.

MXenes‐based flexible electronics for wound monitoring and treatment

Deleted Journal, Год журнала: 2025, Номер unknown

Опубликована: Май 15, 2025

Abstract Wound healing is a dynamic and overlapping bio‐process with varied cellular molecular characteristics involved. Traditional wound dressings have made significant achievements in accelerating healing; however, they lack the ability to monitor changes of wounds, which limits effectiveness management. Currently, development flexible electronics‐based intelligent that can real‐time manner make positive impact on clinical practice. MXenes, also known as type 2D inorganic compound, are generally considered ideal precursors for fabricating electronics. MXenes‐based electronics not only biomarkers wounds (e.g., temperature, pH, lactic acid) but promote by combining other bio‐activities. This review begins brief introduction challenges associated early diagnosis wounds. It then provides comprehensive summary discussion fabrication applications monitoring treatment. Finally, it explores current future directions this cutting‐edge field.

A new two-dimensional (2D) non-MXene transition metal carbide, Mo3C2, was found using the USPEX code. Comprehensive first-principles calculations show that Mo3C2 monolayer exhibits thermal, dynamic, and mechanical stability, which can ensure excellent durability in practical applications. The optimized structures of Lix@(3×3)-Mo3C2 (x = 1–36) Nax@(3×3)-Mo3C2 1–32) were identified as prospective anode materials. metallic sheet low diffusion barriers 0.190 eV for Li 0.118 Na average open circuit voltages 0.31–0.55 V 0.18–0.48 Na. When adsorbing two layers adatoms, theoretical energy capacities are 344 306 mA h g−1 Na, respectively, comparable to commercial graphite. Moreover, substrate maintain structural integrity during lithiation or sodiation process at high temperature. Considering these features, our proposed slab is a potential candidate an material future Li- Na-ion batteries.
