Kerr effect optimization in acetone-immersed optical nanofibers at Salimpour Site.

Finding a green approach for silver nanoparticle (AgNP) synthesis and as an adsorbent for safe contaminant removal in water has become a challenge. In this study, AgNP were green synthesised into a biopolymer matrix (natural rubber latex/polyvinyl alcohol (PVA/NRL)) via electrospinning. Efficiency of the synthesised nanofibre composites in removing mercury (Hg) from an aqueous solution was examined. SEM and TEM analysis showed that AgNP were more visible on the fibre’s surface at a lower concentration (0.01 M AgNP), whilst at a higher concentration (0.015 M AgNP), relatively more AgNP were found within the fibre. The average sizes of the AgNP were relatively larger (8.15 ± 0.09 nm) in 0. 2023-11-01

In this study, a cryogel/nanofiber hybrid material was developed using a new lotus-leaf-inspired strategy. The lotus effect was generated via beaded poly( ε -caprolactone) (PCL) nanofibers produced from the 9 wt% PCL solution with low viscosity and high surface tension via electrospinning. A poly(hydroxyethyl methacrylate) (PHEMA) cryogel layer was constructed through polymerization onto the beaded PCL nanofibrous mat. The thickness of the PHEMA cryogel/beaded PCL nanofiber hybrid material was 3.19 ± 0.07 mm. Morphological characterization studies of the hybrid material were conducted by scanning electron microscopy (SEM). The mean diameter of the beaded PCL nanofibers was 97.22 ± 21.18 nm. 2024-03-01

In this study, uniform Zn 2+ incorporated chitosan nanofibers were first prepared by electrospinning with PEO as the cospinning agent and ZnO as the Zn 2024-08-03

In this study, uniform Zn²⁺ incorporated chitosan nanofibers were first prepared by electrospinning with PEO as the cospinning agent and ZnO as the Zn²⁺ source. Then, these composite nanofibers were carbonized at 600 oC under argon atmosphere to achieve ZnO embedded carbon (Zn@C) nanofibers. Afterward, these ZnO@C nanofibers were annealed at 400 oC under air atmosphere to prepare ZnO nanofibers. SEM, XPS and TEM results confirmed the successful preparation of ZnO nanofibers. The BET analysis shows that the surface area of ZnO nanofibers was up to 154.5 m²/g. These ZnO nanofibers exhibited excellent adsorption performance for Congo red with adsorption capacity of up to 224.2 mg/g. 2024-08-01

Particulate matter and volatile organic compounds (VOCs) are major sources of air pollution both indoors and outdoors. Recently, air pollution from particulate matter and VOCs has become a significant threat to human health. Nanofiber membranes, known for their high strength, large specific surface area, fine dimensions, and flexibility, offer numerous advantages and are widely used in filtration applications. This study prepared a series of Pt/Co 3 O 4 -CeO 2 @PI nanofiber filters with catalytic properties using electrospinning, wet impregnation, and thermal treatment. The results reveal that the Pt/Co 3 O 4 -CeO 2 @PI nanofiber membrane, produced via electrospinning, 2025-02-01
