Effect of solution-blown polyamide-6 nanofiber interlayer on drilling performance of carbon fiber reinforced composites at Salimpour Site.

Objective: This study aims to formulate a ketoconazole patch containing electrospun nanofibres and enhance the solubility due to theincreased particle surface using the electrospinning method. Methods: The Design-Expert version13 software was used in experimental designing, to ensure an efficient nanofiber preparation process. Several nanofiber formulations were prepared with different concentrations of drug and polymers. In this study, Ketoconazole was selected as the model drug, ketoconazole is widely used as an antifungal drug in the treatment of fungal infections. Eudragit and Polyethylene glycol polymers were used with ketoconazole to formulate electrospun nanofibers. 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

This study successfully fabricated polyacrylonitrile (PAN) nanofiber in various thicknesses as particulate matter (PM) filtration membranes using the electrospinning method. The PM source used was derived from cigarette smoke. Scanning electron microscopy (SEM) images and Fourier-transform infrared (FTIR) spectra are provided in the manuscript to observe the morphology and chemical composition of the fabricated nanofiber membrane. The thickness of the nanofiber was controlled based on the volume of the polymer solution, which was 4 mL, 6 mL, and 8 mL, and had a thickness of (52 ± 2) µm, (176 ± 27) µm, and (479 ± 38) µm, respectively (denoted as NF-4, NF-6, and NF-8 membranes). 2024-12-01

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

This study presents a comparative investigation into the effects of four different nanofibers—PA66, PStX, PAN, and PVB—on the mechanical performance and failure mechanisms of epoxy adhesive films. These nanofiber‐reinforced adhesive layers were manufactured via a dry‐reinforcement resin film infusion method and tested under uniaxial tensile loading. Mechanical results showed that PA66 and PStX nanofibers improved tensile strength by up to 25%, primarily by mitigating crack initiation at free edges and promoting effective fiber–matrix bonding. In contrast, PAN nanofibers induced micro‐cracks at the fiber–resin interface, amplifying crack coalescence and reducing strength by 25%. 2025-03-01
