Developing nanofiber membrane materials with dual functionality for VOCs and particulate matter removal at Salimpour Site.

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

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

Green polymers and nanocomposites are noticed by researchers in the environmental fields. Among them, starch, polylactic acid, and cellulose nanofiber (CNF) are eco-friendly. In the present study, thermoplastic bio-nanocomposites of starch/cellulose nanofiber (SN), polylactic acid/cellulose nanofiber (PN), and starch/polylactic acid/cellulose nanofiber (SPN) are prepared by film casting. The effect of nanofibers is investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), mechanical properties, and water vapor permeability (WVP) of films. Results show that the mechanical properties of SN and PN improve with the addition of CNFs due to their uniform dispersion which are 2024-10-01

Antibacterial materials are increasingly significant, particularly for biomaterials and food packaging applications. Materials with good elasticity and antibacterial properties are crucial in this line of work. This study focused on the investigation of nanofiber properties in elasticity and antibacterial by combining Moringa oleifera (MO) zinc oxide nanoparticles (ZnO NPs) with polyvinyl alcohol (PVA) nanofiber. The PVA/MO/ZnO nanofiber is fabricated using the electrospinning method. The morphology of PVA/MO/ZnO nanofiber shows smooth and uniform fibers with 292 nm in diameter size. The EDX mapping also demonstrates the successful loading of ZnO NPs into fibers, 2024-12-01
