The aqueous extract of Chinese winter jujube (Ziziphus jujuba Mill. cv. Dongzao) was used as reducing and capping agents for the synthesis of silver nanoparticles (AgNPs) for the first time. The resulting AgNPs were characterised by UV/Visible (UV-Vis) spectroscopy, atomic force microscope, transmission electron microscopy, selected area electron diffraction, X-ray diffraction, scanning electron microscopy,...
The present work was focused on isolating a bacterial strain of Pseudomonas sp. with the ability to synthesise AgNPs rapidly. A strain of Pseudomonas aeruginosa designated JO was found to be a potential candidate for rapid synthesis of AgNPs with a synthesis time of 4h in light, at room temperature which is a shorter time period noticed for the synthesis when compared to the previous reports Biosynthesis...
Poly(ester-imide)s (PEI)s are a kind of non-vinyl polymers which can be prepared via step-growth polymerization. They contain ester and imide linkages in the polymer backbones and lately show significant applications, such as adhesives, printed circuit boards, membranes, and engineering thermoplastics. Synthesis of chiral polymers is an important field in macromolecular science, they have attracted...
Recently gold/iron oxide composite nanoparticles have attracted much attention as promising biomedical materials. In this paper, a novel laser soldering method called 'nano-soldering' is employed to prepare gold/iron oxide composite nanoparticles. The structural properties were examined by X-ray diffractometry (XRD), field emission scanning electron microscopy (FE-SEM) and transmission electron microscopy...
The purpose of this study was to prepare a 3D nanocomposite bone substitute prepared from gelatin (GEL) and synthesized hydroxyapatite (HAP) in order to mimic natural bone feathers through a novel layer solvent casting combined freeze-drying technique. The adhesion between superimposed layers was ensured by applying a GEL solution. Furthermore, samples were cross-linked with 1% glutaraldehyde (GA)...
