Stretchable electronics have experienced remarkable progress, especially in sensors and wireless communication systems, attributed to their ability to conformably contact with rough or uneven surfaces. However, the development of complex, multifunctional, and high‐precision stretchable electronics faces substantial challenges, including instability at rigid‐soft interfaces and incompatibility with traditional high‐precision patterning technologies. Metallized electrospun nanofibers emerge as a promising conductive filler, offering exceptional stretchability, electrical conductivity, transparency, and compatibility with existing patterning technologies. Here, this review focuses on the fundamental properties, preparation processes, patterning technologies, and application scenarios of conductive stretchable composites based on metallized nanofibers. Initially, it introduces the fabrication processes of metallized electrospun nanofibers and their advantages over alternative materials. It then highlights recent progress in patterning technologies, including collector collection, vapor deposition with masks, and lithography, emphasizing their role in enhancing precision and integration. Furthermore, the review shows the broad applicability and potential influence of metallized electrospun nanofibers in various fields through their use in sensors, wireless systems, semiconductor devices, and intelligent healthcare solutions. Ultimately, this review seeks to spark further innovation and address the prevailing challenges in stretchable electronics, paving the way for future breakthroughs in this dynamic field.

High-voltage LiNi0.5Mn1.5O4 spinel material is plagued by severe capacity fading in full cells paired with carbon anode, presumably due to the consumption of active Li+ ions induced by the decomposition of electrolyte, as well as the dissolution of transition metal ions form LNMO cathode and the following deposition on carbon anode. Surface coating is considered as an effective means to alleviate the capacity fading of LNMO/carbon full cell. Mesocarbon microbeans (MCMB) particles are coated with different amounts of Al2O3 via a double hydrolysis reaction between Al(NO3)3 and NaAlO2 followed by post-annealing process. It is found that MCMB sample coated with 1 mol% Al2O3 shows better overall electrochemical performance in MCMB/Li half cell. LNMO cathode is also coated with Al2O3 via the same method. It is found that LNMO/MCMB full cell consisting of Al2O3 coated LNMO and MCMB exhibits the best cycling performance. On the cathode side, Al2O3 coating alleviates the interfacial reaction between cathode and electrolyte and the dissolution of transition metal ions from LNMO. On the anode side, Al2O3 coating with proper thickness acts as an artificial SEI to suppress electrolyte decomposition and stabilize SEI during cycling, thus reducing the consumption of active Li+ ions. Furthermore, Al2O3 coating can scavenge HF from the electrolyte, and then form a stable and effective protective layer on electrode surface. [ABSTRACT FROM AUTHOR]

Mitsugumin 23 (MG23) has been identified as a ball-shaped cation channel in the sarcoplasmic reticulum (SR) but its physiological role remains unclear. This study aimed to examine the contribution of MG23 to Ca 2+ storage function in skeletal muscle by using Mg23 -knockout ( Mg23 -/- ) mice. There was no difference in the isometric specific force of the extensor digitorum longus (EDL) and soleus (SOL) muscles between Mg23 -/- and wild-type (Wt) mice. In Mg23 -/- mice, the calsequestrin 2 content in the EDL muscle and SR Ca 2+ -ATPase 2 content in the SOL were increased. We have examined SR and myofibril functions using mechanically skinned fibers and determined their fiber types based on the response to Sr 2+ , which showed that Mg23 -/- mice, compared with Wt, had: 1 ) elevated total Ca 2+ content in the membranous components including SR, mitochondria, and transverse tubular system referred to as endogenous Ca 2+ content, in both type I and II fibers of the EDL and SOL; 2 ) increased maximal Ca 2+ content in both type I and II fibers of the EDL and SOL; 3 ) decreased SR Ca 2+ leakage in type I fibers of the SOL; and 4 ) enhanced SR Ca 2+ uptake in type I fibers of the SOL, although myofibril function was not different in both type I and II fibers of the SOL and EDL muscles. These results suggest that MG23 decreases SR Ca 2+ storage in both type I and type II fibers, likely due to increased SR Ca 2+ leakage. NEW & NOTEWORTHY The function of calcium storage within sarcoplasmic reticulum (SR) plays a pivotal role in influencing the health and disease states of skeletal muscle. In the present study, we demonstrated that mitsgumin 23, a novel non-selective cation channel, modifies SR Ca 2+ storage in skeletal muscle fibers. These findings provide valuable insights into the physiological regulation of Ca 2+ in skeletal muscle, offering significant potential for uncovering the mechanisms underlying muscle fatigue, muscle adaptation, and muscle diseases.

In order to alleviate the rapid capacity decay caused by the instability of the crystal structure and electrode/electrolyte interface, a series of Li 2 SiO 3 -coated LiNi 0.5 Mn 1.5 O 4 materials have been prepared via the lithium acetate-assisted sol-gel method followed by a short-term calcination process. During the sol-gel process, TEOS is hydrolyzed, condensed, and polymerized with the assistance of lithium acetate to form a Li + -embedded [Si-O-Si] n network structure to ensure the uniformity of the coating. By changing the amount of TEOS and lithium acetate, the coating thickness can be precisely controlled, whose effects on the structural and electrochemical properties of LiNi 0.5 Mn 1.5 O 4 materials are intensively investigated. The results show that the material with an appropriate thickness of Li 2 SiO 3 coating exhibits a larger primary particle size and reduced secondary particle agglomeration. The uniform Li 2 SiO 3 coating with appropriate thickness can not only improve Li + ion diffusion kinetics but also suppress side reactions and CEI growth at the electrode/electrolyte interface. Besides, the interaction of Li 2 SiO 3 with HF can alleviate electrode corrosion and the dissolution of transition metal ions. All the abovementioned factors together promote the significant improvement of the electrochemical performance of Li 2 SiO 3 -coated LiNi 0.5 Mn 1.5 O 4 materials.
