Preparation of Homogeneous Regenerated Cellulose Nanofiber based Membrane Adsorber for Membrane Chromatography Applicati 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

Ceramic fibers have the advantages of high temperature resistance, light weight, favorable chemical stability and superior mechanical vibration resistance, which make them widely used in aerospace, energy, metallurgy, construction, personal protection and other thermal protection fields. Further refinement of the diameter of conventional ceramic fibers to microns or nanometers could further improve their thermal insulation performance and realize the transition from brittleness to flexibility. Processing traditional two-dimensional (2D) ceramic fiber membranes into three-dimensional (3D) ceramic fiber aerogels could further increase porosity, reduce bulk density, 2024-05-01

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
