Large-Scale Nanofiber Manufacturing| High-temperature-resistance flexiblepiezoelectric sensor via cyclized PAN/BTOnanofibers 2025-05-26

Long-term operation of equipment in high-temperature extreme environments often involves intense mechanical vibrations, posing higher demands for vibration monitoring technology. In fields such as aerospace, energy equipment, petroleum exploration, and industrial monitoring, traditional flexible piezoelectric sensors face the technical bottleneck of thermal degradation failure, making it difficult to meet long-term monitoring needs in high-temperature environments. Currently, rigid piezoelectric sensors perform well in certain applications, but their large size and limited flexibility restrict their use on complex curved surfaces, dynamic components, and microstructures. Therefore, developing sensing materials that combine high-temperature stability, excellent piezoelectric properties, and good mechanical flexibility is crucial for vibration monitoring in extreme environments.

In June 2024, a major oil spill occurred near Singapore’s Sentosa Island, releasing over 400 tons of fuel into the sea. Similarly, pollution crises have frequently erupted in recent years. Existing remediation materials, such as biomass aerogels, offer advantages like low density and high porosity but face bottlenecks like hydrophilic-induced structural collapse, poor mechanical properties, and limited functionality, failing to meet practical needs.

High-Throughput Electrospinning System| Multicolor Rare-Earth Film with Ultra-Long Afterglow forDiverse Energy-Saving Applications 2025-05-23

Rare-earth long-afterglow materials exhibit revolutionary potential in high-end anti-counterfeiting, biomedical imaging, and smart optoelectronic sensing due to their unique light-trapping and delayed-emission properties. These materials can emit light persistently after excitation ceases, offering innovative solutions for passive lighting and dynamic information encryption. However, traditional rare-earth afterglow systems face multiple technical bottlenecks due to inherent material limitations: their rigid crystal structures result in poor interfacial compatibility with flexible substrates, hindering complex morphology construction via solution processing; their single emission band and difficult tunability limit full-spectrum display requirements; and environmental humidity/temperature variations easily cause deactivation, restricting stable outdoor applications.

High-Throughput Electrospinning System| Multi-bionic Strategies Integration in Cellulose Nanofber-BasedHydrogen-Bonded Ne:twork for Solar-DrivenMetagels with StronWater Evaporation 2025-05-22

Recently, the team of Associate Professor Zhu Ruofei at Xinjiang University published their latest research, "Multi-bionic Strategies Integration in Cellulose Nanofiber-Based Metagels with Strong Hydrogen-Bonded Network for Solar-Driven Water Evaporation", in Advanced Fiber Materials. Although solar-driven interfacial evaporation (SDIE) technology has advanced rapidly in seawater desalination, water evaporation rates remain a persistent bottleneck. Salt ion accumulation and crystallization in specific device areas reduce evaporation efficiency and energy performance, hindering overall evaporation. Thus, salt tolerance and threshold evaporation rates are key challenges for SDIE advancement.

High-Throughput Electrospinning System| Porosity and Conductivity Dual-Gradient Design onUltrathin 3D Nanofbrous Anode for Flexible Zn-lonBatteries 2025-05-22

Aqueous zinc-ion batteries (AZIBs) with high energy density, low cost and excellent safety are considered one of the most promising flexible energy storage units. However, their flexible anode design faces two major challenges: (1) dendrite growth caused by non-uniform zinc deposition affecting battery stability; (2) conventional zinc foil's shape memory and metal fatigue characteristics making it unsuitable for flexible batteries. Therefore, there's an urgent need to develop new strategies for preparing highly flexible zinc anodes while effectively regulating zinc deposition behavior to suppress dendrite growth and maintain AZIBs' long-term cycling stability.
