Degradation of Carbon Nanofiber-Reinforced Composite Under Loading and Environmental Conditions at Salimpour Site.

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

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

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
