Summary: This study reveals that electrospun silica nanofiber membranes have great potential in environmental applications, but their mechanical performance is not well known. Compared to conventional nanofiber membranes, silica nanofiber membranes exhibit a completely different deformation behavior due to their unique chemical and physical properties. Additionally, storing the membranes at room temperature results in significant changes in failure mechanisms, which can be accelerated through thermal treatment. These findings demonstrate the possibility of mechanical tunability in silica nanofiber membranes by adjusting the storage or treatment conditions.

Summary: Multiferroic BiFeO3 particles with size of about 50 nm and good crystallinity were prepared via a simple sol-gel method and annealing. The VOCs sensing properties of BiFeO3 sensor were tested under both traditional thermal excitation and synergetic thermal-magnetic excitation, and the results showed improved performance under the latter condition. The effect of magnetic field on the sensor can be attributed to decreased defects on domain walls, excitation of gas molecules, and activation of surface-absorbed oxygen species.

Summary: xCuO-(1-x)Fe2O3 composite nanofibers for gas-sensing applications were investigated using on-chip electrospinning. The composite nanofibers showed improved sensor response compared to single metal oxides. The optimal composition of 0.5CuO-0.5Fe2O3 formed a complex oxide of copper ferrite (CuFe2O4) and exhibited the highest response to H2S and NO2 gases. The gas-sensing performance was attributed to the nanograin-based structure, formation of CuFe2O4 oxide, and heterojunctions in the composite nanofibers.

Summary: In this study, biocompatible ultrafine fibers based on talc nanosheets (TNS)/PVDF composites were fabricated, showing robust electromechanical responses. Piezoresponse force microscopy (PFM) was used to analyze ferroelectric and piezoelectric coefficients. The 0.5 wt% TNS dispersed ultrafine fibers exhibited well-defined ferroelectric characteristics with an enhanced piezoelectric coefficient (d(33)) of approximately 43.3 pm/V. The piezoelectric coefficients strongly depended on the morphology and electroactive phase fraction of the composite ultrafine fiber. In vitro cytotoxicity tests showed that the TNS/PVDF composite ultrafine fibers had no cytotoxic response and promoted cell viability. These TNS/PVDF piezoelectric ultrafine fibers are thus suitable for bioelectronics applications, especially as flexible wearable electronic devices and sensors.

It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
