The biocompatibility of electrospun PVA with monolayer graphene obtained by chemical vapor deposition (PVA/CVD-grown MLG) nanocomposite was investigated. properties PVA/CVD-grown MLG were compared those mat. Raman analysis confirmed the presence on PVA. Although no significant changes in tensile observed, electrical conductivity increased from 0.1 (PVA mat) to 0.4 μS/cm MLG). Thermal stability also increased, as evidenced higher onset temperature and maximum decomposition rate determined TGA. contact angle decreased slightly, which resulted PBS absorption degradation nanocomposite. Water transmission (WVTR) 40 37 g/m2 h Cell culture studies showed better cell viability, population, growth case due improved physical, mechanical properties.

Abstract In this study, we employ first principles calculations within the framework of density functional theory to comprehensively investigate energetic stabilities and electronic properties various nitrogen dopant-vacancy complexes: N C V H , CH in graphane two-dimensional material. The creation complexes require less energy than that according formation analysis. binding energies analysis reveals all considered N-vacancy are stable when compared their isolated counterparts. Based on U-parameter values derivation, it is easier for complex (1.09 eV) undergo transition from one charge state another as (2.52 eV). induce acceptor donor states band gap, which alters during (0 −1 or 0 +1). This comparative study has provided fundamental insights into possibilities utilizing nitrogen-vacancy centers gap engineering nano-technology tailored applications.

Graphene materials and their derivatives have shown promising capabilities in removing anionic cationic dyes from wastewater. The present study aims at the synthesis of graphene-based material with a high specific surface area evaluates its use as an adsorbent for toluidine blue methyl violet aqueous solutions. physicochemical characterization before after dye adsorption is made by XRD, Raman spectroscopy, SEM, TEM, nitrogen physisorption, TG-DTA, XPS. influence solution's pH, contact time, concentration, temperature on efficiency investigated. demonstrated capacity towards (265.2 mg.g-1) (200.4 water. process both follows Langmuir model involves physical rather than chemical interactions. Kinetic parameters were also determined. studied can be attributed to combination mechanisms, including electrostatic interactions, hydrogen bonding, π-π interactions between molecules aromatic structure reduced graphene oxide. findings work highlight possibilities enhancing materials' capabilities.
