Phytoextract mediated ZnO/MgO nanocomposites for photocatalytic and antibacterial activities

Abstract: This paper discusses the investigation of pure MgO, ZnO nanoparticles (NPs) and ZnO/MgO nanocomposites (NCs) via plant based green assisted simple, fast, economical and environmental friendly method with the help of Ricinus communis L. plant seedless fruit extract (SFE). The green route synthesized NPs and NCs calcinated at the temperature of 450 °C were used for further optical studies with ultraviolet–visible spectroscopy (UV–vis), structural studies by X-ray diffraction (XRD), functional analysis by Fourier-transform infrared spectroscopy (FTIR), microscopic determination by scanning electron microscope and transmission electron microscope (SEM, TEM), elemental composition analyzed by using Energy-dispersive X-ray spectroscopy (EDX). Successfully synthesized and characterized NPs and NCs were, further, used for the antibacterial studies towards Escherichia coli (E.coli), Klebsiella bacteria(s) and photocatalytic activity towards methylene blue (MB). In comparison to the pure NPs and NCs, the ZnO/MgO-NCs (1:1) exhibited an enhanced antibacterial activity and resulted in 1.5–2.8 times and 1.27–3.5 times larger radius for zone of inhibition in case of E.coli and Klebsiella respectively, where as the value for photocatalytic apparent rate constant was found to be 1.49–5.25 times more.

Third harmonic flow of charged particles in Au + Au collisions at √sNN = 200 GeV

Abstract: In this proceedings, we report measurements of the third harmonic coefficient of the azimuthal anisotropy, v3, known as triangular flow. The analysis is for charged particles near midrapidity in Au+Au collisions at GeV, based on data from the STAR experiment at the Relativistic Heavy Ion Collider. Triangular flow as a function of centrality, pseudorapidity and transverse momentum are reported using various methods, including a study of the signal for particle pairs as a function of their pseudorapidity separation. Results are compared with other experiments and model predictions.

Traditional knowledge on zootherapeutic uses by the Saharia tribe of Rajasthan, India

Abstract: The present zootherapeutic study describes the traditional knowledge related to the use of different animals and animal-derived products as medicines by the Saharia tribe reside in the Shahabad and Kishanganj Panchayat Samiti's of Baran district of Rajasthan, India. A field survey was conducted from April to June 2006 by performing interview through structured questionnaire with 21 selected respondents, who provided information regarding use of animals and their products in folk medicine. A total of 15 animal species were recorded and they are used for different ethnomedical purposes, including cough, asthma, tuberculosis, paralysis, earache, herpes, weakness, muscular pain etc. The zootherapeutic knowledge was mostly based on domestic animals, but some protected species like the peacock (Pavo cristatus,), hard shelled turtle (Kachuga tentoria), sambhar (Cervus unicolor) were also mentioned as medicinal resources. We would suggest that this kind of neglected traditional knowledge should be included into the strategies of conservation and management of faunistic resources. Further studies are required for experimental validation to confirm the presence of bioactive compounds in these traditional remedies and also to emphasize more sustainable use of these resources.
