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

Due to changing lifestyles, millions of people worldwide experience dry eye disease (DED). The treatment for DED primarily involves the topical use of artificial tears and anti-inflammatory eye drops. Frequent administration of conventional eye drops leads to reduced patient adherence. This study aims to improve the convenience and reduce the dosing frequency, by designing dexamethasone sodium phosphate (DSP)-loaded multilayer nanofiber inserts (MLNI) for managing DED. The drug-loaded electrospun nanofibers were sandwiched between two blank nanofiber scaffolds. The outer nanofiber scaffolds will aid mucoadhesion and lubricate the cornea to reduce the dryness. 2024-12-01

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

This study presents a novel approach to converting electrospun polyacrylonitrile (PAN) nanofiber bundles into rovings, essential for nanofiber yarn spinning, through the implementation of false twisting and drawing processes. The false twisting process is optimized by varying the input bundle angle (40° to 60°), twister type (A, B, C), and rotation speed (20, 50, and 80 rpm). A bundle input angle of 55°, twister type B, and a twister rotation speed of 80 rpm show the best results in terms of longer twisted length, lower average thickness, and thickness variation values. The morphological, physical, and mechanical properties of the resulting nanofiber rovings for drawing process 2025-02-01
