Sorption of mercury from water by green synthesised silver nanoparticles supported on natural rubber latex/polyvinyl 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

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

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

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

In this study, a novel handheld battery-operated electrospinning device equipped with a nanofiber concentrator was developed to enhance target area control during nanofiber deposition. The device manipulates the electric field using the dielectric properties of a polymeric tunnel, enabling precise deposition of nanofibers with specific patterns. Low molecular weight chitosan/poly(vinyl alcohol) (CS/PVA) nanofibers with an average diameter of 65 ± 9 nm were successfully synthesized. Finite Element Analysis (FEA) simulations demonstrated the effectiveness of the nanofiber concentrator in stabilizing the whipping jet, reducing deposition area, and increasing accuracy. 2025-02-01
