Effect of solution-blown polyamide-6 nanofiber interlayer on drilling performance of carbon fiber reinforced composites in ssalimpour

Finding a green approach for silver nanoparticle (AgNP) synthesis and as an adsorbent for safe contaminant removal in water has become a challenge. In this study, AgNP were green synthesised into a biopolymer matrix (natural rubber latex/polyvinyl alcohol (PVA/NRL)) via electrospinning. Efficiency of the synthesised nanofibre composites in removing mercury (Hg) from an aqueous solution was examined. SEM and TEM analysis showed that AgNP were more visible on the fibre’s surface at a lower concentration (0.01 M AgNP), whilst at a higher concentration (0.015 M AgNP), relatively more AgNP were found within the fibre. The average sizes of the AgNP were relatively larger (8.15 ± 0.09 nm) in 0. 2023-11-01

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

The aim of this study was to develop polyvinyl alcohol (PVA)/carboxymethyl cellulose (CMC)/graphene oxide (GO) nanofiber mats using electrospinning fabrication technique. Polymer solutions were prepared with PVA at a concentration of 6% w/v, CMC ranging from 0.5% to 1.5% w/v, in a 1:1 polymer blend ratio, and GO nanofiller from 0.1% to 0.5% w/v. Addition of CMC and GO amend the solution properties such as conductivity and viscosity, leading to notable alteration in nanofiber diameters from 90.514 to 169.225 nm. As evidenced by rheological analysis, addition of GO significantly enhanced the storage moduli and shear stress of PVA/CMC/GO solutions compared to PVA and PVA/CMC. 2025-01-01

Field-effect transistors (FETs) based on indium oxide (In2O3) nanofibers demonstrate significant potential for applications in next-generation electronic devices. However, In2O3 nanofiber FETs typically exhibit deteriorated electrical performance and bias stability due to the disordered arrangement of nanofibers and a high concentration of oxygen vacancy defects. In this study, In2O3 nanofibers were prepared by electrospinning, and the effects of nanofiber orientation and Y2O3 passivation on FET electrical performance were systematically investigated. The results indicate that after Y2O3 passivation, the aligned In2O3 nanofiber FETs exhibit enhanced electrical performance and superior 2025-02-01
