Article Title: A bilayer mupirocin/bupivacaine-loaded wound dressing based on chitosan/poly (vinyl alcohol) nanofibrous mat: Preparation, characterization, and controlled drug release.
Article Snippet: An infected skin wound caused by external injury remains a serious challenge.. Electrospun drug-loaded nanofibers with antibacterial properties based on biopolymers have been widely explored for wound healing.. In this study, the double-layer CS/PVA/mupirocin (CPM) + CS/PVA/bupivacaine (CPB) mats were prepared by electrospinning method (20 % polymer weight) and then crosslinked with glutaraldehyde (GA) to optimize the water-resistant and biodegradation properties for wound dressing applications.

Article Title: Bioceramic calcium phosphate-polymer scaffolds: A promising strategy for osteochondral repair and regenerative medicine
Article Snippet: The study’s objective was to fabricate a porous scaffold with desirable biological and bioactive characteristics, utilizing freeze-drying with polyvinyl alcohol (PVA).. Subsequently, compressive strength tests and simulated body fluid (SBF) soaking experiments were performed to assess the mechanical and biological properties of the scaffold.. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used for analyzing the scaffolds.

Article Title: Elucidating the Morphology of the Endoplasmic Reticulum: Puzzles and Perspectives
Article Snippet: The PVA with a molecular weight of M w = 145 kDa was purchased from Merck, Germany.

Article Title: Facile Z-scan determination of nonlinear refractive index and absorption coefficient of dye-doped polymer film
Article Snippet: Herein, we report the nonlinear refractive index and nonlinear absorption coefficient of anthraquinone dye (disperse blue 14)-doped polymer film using a facile Z-scan technique.. The Z-scan studies were carried out using a semiconductor diode laser with a constant power output of 5 mW at a wavelength of 635 nm as the source of excitation.. The Z-scan technique consists of closed and open aperture methods, which revealed the self-defocusing and reverse saturable absorption mechanisms based optical nonlinearity.

Article Title: Electrospinning and characterization of lignin nanofibers as pH-responsive hydrogel with antibacterial activity and biocompatibility in biomedical application
Article Snippet: Lignin is a biocompatible, biodegradable and renewable biopolymer with macromolecular structure that can be used in production of hydrogel network.. The main aim of this research was to electrospin lignin hydrogel in the form of nanofibers by engineering the polymer structure to form stimuli-responsive lignin nanofibers in alkaline pH.. For this purpose, a blend of lignin/PVA (polyvinyl alcohol) and citric acid as a friendly cross-linker were electrospun.

Article Title: Selective laser sintering of distinct drug and polymer layers as a novel manufacturing strategy for individually dosed tablets.
Article Snippet: This ensured that the temperature was below the melting points of IND (158–162 ◦C) (European Pharmacopoeia, 2024d) and PVA (160–240 ◦C) (Merck KGaA, 2025) to prevent melting in the powder supply tanks.

Article Title: Fabrication of antibacterial bio‐composite from polyvinyl alcohol incorporated with <i>Azadirachta indica</i>
Article Snippet: PVA with a molecular weight of 115,000; DP of 1700–1800; viscosity 25–32 cps; and 98%–99% hydrolyzed granules were sourced from Merck, Darmstadt (Germany).

Article Title: Poly(vinyl alcohol)/Pullulan/NaCl Conductive Hydrogels with High Strength and Sensitivity for Wearable Strain Sensors
Article Snippet: Ionic conductive hydrogels have emerged as promising candidates for wearable sensors.. However, it is still challenging to fabricate hydrogels simultaneously with a balanced mechanical strength, ionic conductivity, and sensitivity.. In this work, Poly(vinyl alcohol) (PVA)/Pullulan/Sodium chloride (NaCl) ionic conductive hydrogels were prepared by soaking frozen−thawed PVA/Pullulan hydrogels in NaCl solution to obtain the balanced properties.
