ZnO Nanofiber Derived from Zinc Loaded Chitosan Nanofiber as an Efficient Adsorbent for Congo Red from Aqueous Solution at Salimpour Site.

As the global facial mask market continues to grow, consumers have put forward higher requirements for the functionality and ingredients of mask products. Ordinary facial masks mostly use ordinary non-woven fabrics as the mask base fabric and are used with essence. Preservatives are generally added. At the same time, they are susceptible to the influence of the external environment and are easily oxidized, causing the mask to deteriorate and cause skin allergic reactions. In addition, traditional facial masks have problems such as poor fit with the skin, poor breathability, insufficient absorption of nutrient solutions, and easy dripping. 2024-06-01

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

In this study, we developed a new technique, simultaneous foam electrospinning and electrospraying (FE/E), that produces nanofiber/nanoparticle electrodes at higher production rates compared to needle‐based electrospinning and electrospraying (E/E). Herein, the nanofiber amount was precisely controlled by applying various voltages on the foam electrospinning process at a fixed platinum (Pt) loading, which enables an exclusive investigation into the impact of ionomer nanofiber on fuel cell performance at ultra‐low Pt loadings for proton exchange membrane fuel cells. The results show that fuel cell performance is strongly dependent on ionomer nanofiber content. At 0. 2024-11-01

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

Proc. 2025, 21, 1. Abstract: Carbon nanofiber mats can be applied for diverse energy applications. Usually, they should be freestanding and show sufficient structural stability. Poly(acrylonitrile) (PAN) is often used as the base material for electrospinning due to its high carbon yield during carbonization. Carbonized PAN nanofiber mats, however, may be brittle and break under mechanical load. Here, we report a study of the impact of ZnO and tetraethyl or-thosilicate (TEOS) as nanoparticle additives on the 2025-02-01
