Palladium-Nanoparticles Biohybrids in Applied Chemistry

Green Chemistry Approach for Synthesis of Effective Anticancer Palladium Nanoparticles.

The purpose of this study was to design and synthesize Palladium nanoparticles (PdNPs) using an environmentally friendly approach and evaluate the in vitro efficacy of PdNPs in human ovarian cancer A2780 cells. Ultraviolet-Visible (UV-Vis) spectroscopy was used to monitor the conversion of Pd(II) ions to Pd(0)NPs. X-ray diffraction (XRD) revealed the crystallinity of the as-synthesized PdNPs an...

Metadiscourse in Applied Linguistics and Chemistry Research Article Introductions

This study examined disciplinary rhetoric in research articles, focusing on different traditions in structuring text discourses from a metadiscourse-move analytic approach. The corpus consisted of 72 research article Introductions (RAIs): 36 in applied linguistics and 36 in chemistry. Swales’ CARS model (1990, 2004) and Hyland’s interpersonal model of metadiscourse (2005) were used as analytica...

Microbial synthesis of core/shell gold/palladium nanoparticles for applications in green chemistry

We report a novel biochemical method based on the sacrificial hydrogen strategy to synthesize bimetallic gold (Au)-palladium (Pd) nanoparticles (NPs) with a core/shell configuration. The ability of Escherichia coli cells supplied with H(2) as electron donor to rapidly precipitate Pd(II) ions from solution is used to promote the reduction of soluble Au(III). Pre-coating cells with Pd(0) (bioPd) ...
