Large-Scale Nanofiber Manufacturing| Electrospun FeVO4 nanofibers-based gassensor with high selectivity and fastresponse towards n-butanol 2025-05-16

In recent years, detection of toxic gases like NO2, H2S, and n-butanol has gained increasing attention. n-Butanol, a common industrial solvent and chemical synthesis intermediate, is widely used in chemical and pharmaceutical fields. However, being toxic and highly flammable, prolonged exposure may irritate skin and eyes, even paralyze the nervous system, causing serious health issues. Therefore, developing novel n-butanol gas-sensitive materials is crucial for personnel and environmental safety.

Large-Scale Nanofiber Manufacturing| An intelligent nanofiber membrane withdual-asymmetric wettability enablingSpontaneous directional water and oiltransportation in opposite direction 2025-05-16

With continuous socioeconomic development, oil-water separation has become essential in many fields, demanding processes with low energy consumption, high efficiency, and high speed. In recent years, fiber membrane materials with special wettability (e.g., superhydrophobic or superoleophilic) have attracted widespread scientific attention and found broad applications.Directional liquid transport textile materials (also called "unidirectional liquid transport", referring to spontaneous unidirectional liquid transport through membrane thickness) represent emerging smart materials with excellent prospects in oil/water collection and directional fluid transport. However, existing unidirectional materials only transport specific liquids unidirectionally (either water or oil), limiting their use in complex mixtures like emulsions. A material capable of simultaneously transporting water and oil in opposite directions ("bidirectional liquid transport") would enable two-way separation for more

Large-Scale Nanofiber Manufacturing| Radially unfolded nanosheets inpolyacrylonitrile nanofibers: A biomimeticsconstruct of high-performance anode forlithium-ion batteries 2025-05-16

Lithium-ion batteries (LIBs), with advantages such as high output voltage, long cycle life, safety, and pollution-free operation, remain core devices in the development of future energy storage technologies as the current mainstream electrochemical energy storage products in the market. As one of the key components of LIBs, commercial graphite anodes have reached their theoretical limits and can hardly meet the growing demands of our era. Additionally, traditional energy storage devices generally possess mechanical rigidity and cannot meet the societal need for wearable flexible products. Therefore, the development and utilization of lightweight carbon-based fiber electrode materials represent a highly promising research field.

Large-Scale Nanofiber Manufacturing| Hydrophilic-hydrophobic structure ofANF/MFC separator for high-stable dendritefree aqueous zinc-ion batteries 2025-05-16

Aqueous zinc-ion batteries (AZIBs) are considered one of the most promising next-generation battery energy storage systems. Their high theoretical capacity (820 mAh g-1) and low redox potential (-0.762 V vs SHE) have attracted significant research attention. Additionally, AZIBs' aqueous electrolytes offer advantages like non-toxicity and high safety. However, AZIBs still face application challenges including uncontrolled zinc dendrites, side reactions, hydrogen evolution reaction (HER), and passivation. Deterioration of Zn anodes leads to reduced Coulombic efficiency and short circuits, severely hindering AZIB development.

Large-Scale Nanofiber Manufacturing| Self-powered superhydrophobic/oleophobicFR-PVDF/PA6 nanofiber membrane for longterm efficient filtration and respiratorymonitoring 2025-05-15

The acceleration of industrialization and worsening atmospheric pollution severely endanger public safety, becoming a globally critical concern. Suspended particulate matter (PM) with small particle sizes in the atmosphere is a major culprit of air pollution, significantly impacting air quality and human health. Highly permeable airborne particles (PM ≤ 0.3 μm) can carry toxic substances and deadly viruses, entering human bronchi and alveoli through respiration, causing lung damage. Thus, developing effective PM filters is imperative, especially smart air filters with self-powering or sensing capabilities, which will be a future research focus.

Large-Scale Nanofiber Manufacturing| Cellular Spatial sensing Determines Cell MechanotransductionActivity on the Aligned Nanofibers 2025-05-14

Fiber-based tissue engineering has become crucial for designing scaffolds that closely mimic the extracellular matrix (ECM). The ECM consists of complex fiber networks with varying alignment patterns. Electrospun nanofibers are widely used as scaffold materials in tissue engineering, but how cells respond to differently aligned fibers remains controversial. Some studies suggest aligned fibers promote osteogenic differentiation, while others show random alignment works better. This contradiction stems from insufficient understanding of how cells perceive fiber spatial characteristics.From a mechanobiological perspective, regardless of external conditions, cell behavior is primarily governed by intracellular traction forces. These forces are generated through actin stress fibers and transmitted to the ECM via focal adhesions, then converting mechanical signals into nuclear responses that influence chromatin structure and gene expression. This mechanical feedback loop regulates cell morph
