The present work deals with the studies of the host matrix nature of pure and structurally modified surface roughened and coaxial hollow electrospun poly(methyl methacrylate) (PMMA) nanofibers to lead sulphide (PbS) quantum dots. The various structural and molecular analyses conducted on these samples proved the advancements and structural modifications made in the properties of pure PMMA nanofibers by electrospinning and selective dissolution. The successful incorporation of the quantum dots to pure and structurally modified PMMA nanofibers and hence the host matrix nature of these nanofibers is proved by different spectral analyses of the samples. The coaxial hollow PMMA nanofibers are found to be the best host matrix among these PMMA nanofibers as proved by the optical studies of the samples. Photoluminescence analyses of the samples showed the influence of these quantum dots on the optical properties of PMMA nanofibers. It is observed here that, the quantum dots enhance the intensity of coaxial hollow PMMA nanofibers to about four times than its virgin form. The pure and structurally modified PMMA nanofibers incorporated with PbS quantum dots are proved to be efficient for the degradation of methylene blue dye where coaxial hollow PMMA nanofibers incorporated with PbS quantum dots is the best.

Natural fibers and materials are well known for adsorption studies, whereas synthetic fibers have not received enough attention in this field. Therefore, an attempt is made here to study the adsorption properties of synthetic poly(methyl methacrylate) (PMMA) nanofibers and methods for improving or modifying their adsorption properties. PMMA nanofibers are prepared by the most recent electrospinning technique and the structural, and hence, the adsorption properties of the PMMA nanofibers are modified by preparing them in surface-roughened and coaxial hollow forms through electrospinning. Studies of the adsorption of methylene blue (MB) and brilliant green (BG) dyes by the three types of PMMA nanofiber demonstrate that all the PMMA nanofibers show a certain amount of adsorption. Fiber samples that had adsorbed MB and BG were subjected to various adsorption isotherms which confirmed the multilayer adsorption properties of the fiber samples by satisfying various isotherms, mainly the Freundlich and Elovich adsorption isotherms. Kinetic studies of pure and structurally modified PMMA nanofibers that had adsorbed MB and BG dyes proved that the intraparticle diffusion model applied to these fiber samples. Here, it is also shown that the adsorption properties of electrospun synthetic fibers can be further improved by structural modification using the possibilities of electrospinning.

This study reports a facile, cost‐effective, environment‐friendly, green, and rapid fabrication of spherical silver nanoparticles (Ag NPs) of average grain size of 25 nm within 30 minutes employing the leaf extracts of the Calamus tenuis plant. Characterization was accomplished for determining the morphology, size, crystallinity, and for the identification of functional moieties responsible for the reduction and stabilization. The phytoconstituents present in the leaf extracts of Calamus tenuis played the dual role of reducing as well as stabilizing agents eliminating the need for the addition of any external reducing and capping agents.
