New Phenothiazines Study Findings Have Been Reported from Birla Institute of Technology and Science

May 13, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators publish new report on Phenothiazines. According to news reporting originating from Rajasthan, India, by NewsRx correspondents, research stated, "Using the extracellular fungal proteins, a low cost and eco-friendly synthesis of zinc oxide nanoparticles has been demonstrated in aqueous solvent system. The obtained nanoparticles were characterized by transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDS), UV-visible spectroscopy and powder X-ray diffraction (XRD) measurements."

Our news editors obtained a quote from the research from the Birla Institute of Technology and Science, "The as-synthesized particles were quasi-spherical, symmetrical, polydisperse and well distributed without any aggregation with size predominantly ranging between 80 and 120 nm. Photoluminescence (PL) and fourier-transform infrared (FT-IR) spectroscopy studies revealed that nanoparticles were individually coated with protein molecules that may act as stabilizing agents. Photocatalytic studies for the degradation of methylene blue dye under UV irradiation revealed extremely high photocatalytic activity of protein-capped ZnO nanoparticles (nearly 90% degradation in 30 min) which clearly outperformed commercial bare ZnO nanoparticles (nearly 40% degradation in 30 min) under the same conditions. The remarkable photocatalytic performance originated mainly due to the presence of surface proteins which act as an effectual host for methylene blue dye and facilitates absorption of dye along with low recombination rate of the e(-)/h(+) pairs."

According to the news editors, the research concluded: "The low cost, simplicity and eco-friendly nature of the present protocol for 'one-pot' synthesis and modification of ZnO nanoparticles could be extended to synthesize other metal nanoparticles thus expanding its applicability in various fields."
