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

Nanofiber core-spun yarn (NCSY) combines the advantages of traditional fibers and nanofibers to be widely used in smart wearable textiles, biomedical textiles, and functional textiles. Here, for the first time, the forming process of NCSY and its shape regulation mechanism were explored via finite element analysis and response surface analysis method to obtain mathematical model for predicting the various forms of yarn. As proof-of-concept applications, shape-controllable nanofiber core-spun yarns were prepared for thermal–moisture management and solar steam generation, respectively. The as-obtained shape-controllable PAN nanofiber/cotton composite yarns could achieve an interval control of 2024-04-01

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

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

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
