To enhance the bonding strength between the active material and the core yarn current collector through nano-entanglement, bacterial cellulose/carbon nanotube (BC/CNT) nanofiber yarns were developed using in situ cultivation and wet twisting. This method utilizes the large specific surface area and abundant active functional groups of BC-based nanofibers. Subsequently, V2O5/BC/CNT composite yarn electrodes were fabricated, exhibiting a core-sheath structure with excellent conformal characteristics. The influence of ultrasound duration on the conductivity and electrochromic performance of composite yarns was investigated. The initial discharge-specific capacity was recorded as 105.3 mAh/g, with a capacity retention rate of 60.2% after 100 cycles. The composite yarn exhibited 100 reversible transitions between yellow and blue, with reduction and oxidation response times of 2.35 s and 3.3 s, respectively. The modulation amplitude at 532 nm during the initial cycle was 20.31%, and after 100 cycles, the modulation amplitude retention rate remained at 68%.

While electrospinning is an effective method for fabricating nanofibers with good application prospects,controlling the length of stable section of electrospinning jet is critical and remains *** the paper,the effects of electrospinning parameters on the length of stable section have been investigated experimentally using polyacrylonitrile(PAN).The results based on single factor experiments and orthogonal experiments showed that the stable⁃jet length increased with the increase of solution concentration,receiving distance,voltage and solution flow rate,and decreased with the enhanced concentration of salt which was commonly utilized as additive to facilitate the ***,experimental results based on polyethylene oxide(PEO)and polyvinyl alcohol(PVA)showed that the length of stable section changed with increasing salt concentration,and due to the parametric interaction,the change was distinct under different driving voltages or solution concentration conditions.

Warm-sector rainstorms are highly localized events, with weather systems and triggering mechanisms are not obvious,leading to limited forecasting capabilities in numerical models. Based on the ensemble Kalman filter(PSU-En KF) assimilation system and the regional mesoscale model WRF, this study conducted a simulation experiment assimilating all-sky infrared(IR)radiance for a warm-sector rainstorm in East China and investigated the positive impact of assimilating the Himawari-8 moisture channel all-sky IR radiance on the forecast of the rainstorm. Results indicate that hourly cycling assimilation of all-sky IR radiance can significantly improve the forecast accuracy of this warm-sector rainstorm. There is a notable increase in the Threat Score(TS), with the simulated location and intensity of the 3-hour precipitation aligning more closely with observations. These improvements result from the assimilation of cloud-affected radiance, which introduces more mesoscale convective information into the model's initial fields. The adjustments include enhancements to the moisture field, such as increased humidity and moisture transport, and modifications to the wind field, including the intrusion of mid-level cold air and the strengthening of lowlevel convergent shear. These factors are critical in improving the forecast of this warm-sector rainstorm event.
