Shape-Controllable Nanofiber Core-Spun Yarn for Multifunctional Applications 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

Nanoscale optical fibers, capable of confining light at the nanoscale, exhibit nonlinear effects and generate a strong evanescent field interacting with the surrounding environment. In this study, we compared various nanofibers composed of different glasses, closely matching the refractive index of silica, while immersed in acetone. Our objective was to optimize the Kerr effect contributions from either the core or the cladding, dependent on factors such as nanofiber dimensions, core optical properties, and the effective area of the fundamental mode HE11 both inside and outside the nanofiber core. Our findings reveal that the fluorophosphate (S-FPM3) nanofiber exhibits a dominant Kerr 2024-02-01

Nanofiber technology is emerging as a transformative approach in the fields of wound healing and dermal regeneration, providing innovative solutions that significantly enhance traditional treatment methods. Nanofibers, with their high surface area-to-volume ratio, intrinsic porosity, and mechanical robustness, closely mimic the extracellular matrix, thereby promoting cell adhesion, proliferation, and migration essential for effective tissue repair. This abstract delves into the multifaceted applications of nanofibers in wound care, highlighting their capacity to deliver therapeutic agents in a controlled manner, retain moisture, and provide antimicrobial properties, 2024-07-01

The nanofiber materials of three-dimensional spatial structure synthesized by electrospun have the characteristics of high porosity, high specific surface area, and high similarity to the natural extracellular matrix (ECM) of the human body. These are beneficial for absorbing wound exudate, effectively blocking the invasion of external bacteria, and promoting cell respiration and proliferation, which provides an ideal microenvironment for wound healing. Moreover, electrospun nanofiber dressings can flexibly load drugs according to the condition of the wound, further promoting wound healing. Recently, electrospun nanofiber materials have shown promising application prospects as medical 2024-09-01

As a previous study showed, however, the homogeneity of such large nanofibrous membranes regarding thickness and mass per unit area is relatively low. Here, the homogeneity of a gelatin nanofiber mat was investigated, electrospun by a Nanospider Lab from gelatin. Measurements of the mass per unit area, optical transmission, nanofiber diameter distribution and nanofiber orientation as well as surface roughness in various positions distributed over the nanofiber 2024-10-01
