A flow of He mixed with air was used to produce the dielectric barrier discharge (DBD), at the tip of the torch, using pulsed electric excitation at 12 kV. The torch, operated at a power of 750 mW/mm², was seen to completely degrade the aqueous solutions of the pollutants namely methylene blue (MB), methyl orange (MO) and rhodamine-B (RB), at around 10⁻⁴ M concentrations, the concentration of polluants is one order higher than of routinely used heterogeneous photocatalytic reactions, within 10 min of irradiation time at room temperature. UV Visible spectra of the organic dye molecules, monitored after different intervals of plasma-irradiation, ranging between 1 and 10 min, have been used as tools to quantify their sequential degradation. Further, instead of using He, only air was used to form plasma plume and used for degradation of organic dye which follow similar trend as that of He plasma. Further, Liquid Chromatography Mass Spectroscopy (LCMS) technique has been used to understand degradation pathway of methylene blue (MB) as a representative case. Total organic carbon (TOC) measurements indicates significant decrease in its content as a function of duration of plasma exposure onto methylene blue as a representative case. Toxicity studies were carried out onto Gram negative Escherichia coli. This indicated that methylene blue, without plasma treatment, shows growth inhibition, whereas with plasma treatment no inhibition was observed.1 aBansode, Avinash, H.1 aMore, Supriya, Eknath1 aSiddiqui, Ejaz, Ahmad1 aSatpute, Shruti1 aAhmad, Absar1 aBhoraskar, Sudha, V.1 aMathe, Vikas, L.  uhttp://library.ncl.res.in/content/effective-degradation-organic-water-pollutants-atmospheric-non-thermal-plasma-torch-and01350nas a2200205   4500008004100000245010200041210006900143260000800212300001200220490000800232520061900240100002900859700002000888700002000908700002800928700002100956700001900977700002700996856012101023       2017                        eng d00aRapid synthesis of highly monodispersed silver nanoparticles from the leaves of Salvadora persica0 aRapid synthesis of highly monodispersed silver nanoparticles fro  cOCT  a226-2290 v2053 aWe have demonstrated a one pot green protocol for the synthesis of highly monodispersed silver nanoparticles using leaves of Salvadora persica plant. When the leaf extract of Salvadora persica plant reacted with silver nitrate (AgNO3) solution it resulted in the synthesis of highly monodispersed silver nanoparticles with an average size of 3 nm. These nanoparticles were then completely characterized by UV-Visible spectroscopy, Transmission Electron Microscopy, Energy Dispersive Analysis of X-Rays, X-ray diffraction analysis and Fourier Transform Infrared analysis.
