Expansion of biologically stimulated investigational progressions for the synthesis of nanoparticles is developing into a significant stem of nanotechnology. The bioreduction performance of different plant leaf remove such as Helianthus annus (Asteraceae), Sorghum bicolour, Basella alba (Basellaceae), Oryza sativa, Saccharum ojficinarum and Zea mays (Poaceae) in the synthesis of Ag nanoparticles was examined utilizing UV/Visible spectrophotometry, XRD (X-ray diffraction) and SEM (Scanning Electron Microscopy). Helianthus annus was found to exhibit strong potential for rapid reduction of Ag ions. It was observed that there is no association forever between the colour growth and the augment in absorbance displayed by the nanometal synthesised. The study adds to the corroboration of earlier reports on biosynthesis of nanometals using plant leaf extracts. © 2010 Asian Network for Scientific Information. Source

This study centers on development of the enzyme presentation as a cathode catalyst. Laccase enzyme is immobilized at nano meter scale in quaternary ammonium bromide salt treated Nafion polymers and assorted with high surface area carbon powders that are then deposited onto a solid support to create the cathode electrode. Optimization of the synthesis circumstances resulted in notably enhanced performance toward oxygen reduction reaction. © 2010 Asian Network for Scientific Information. Source

In current study, it reported the synthesis of water soluble; monos disperse Al/Au bimetallic nanoparticles with a middling length of 7 nm. Synthesis engages concurrent reduction of Al3+ and Au3+ in water to give way bimetallic nanoparticles. The elemental content of Al is 1.5%. Nanoparticles display ferromagnetic performance as deliberate by SQUID. These particles can be effortlessly conjugated to thiolated DNA, as confirmation by mobility shifts in agarose gel electrophoresis. Nanoparticles heat in solution to temperatures above 40°C, representative appropriateness for hyperthermia. © 2010 Asian Network for Scientific Information. Source

We investigate the reflection of laser pulse from a uniformly moving mirror at relativistic speeds in the general case of inclined mirrors. We use geometrical optics to derive general relations for length, frequency, wavelength and electric field of the pulse after reflection from inclined mirror in the lab frame. In addition, the pulse geometric deformation from reflection is investigated and simulated in two dimensions. © 2015 Elsevier GmbH. All rights reserved. Source

In this research article, a novel, selective, and sensitive modified carbon paste electrode (CPE) using CdS quantum dots (QDs) is presented. The highly stable CdS QDs were successfully synthesized in an in situ process using Na2S2O3 as a precursor and thioglycolic acid as a catalyst and capping agent. The synthesis of CdS QDs was studied using X-ray diffraction (XRD) and transmission electron microscopy (TEM) techniques. The synthesized CdS QDs were used for preparation of a modified carbon paste electrode (CdS/CPE). The electrochemical behavior of the electrode toward p-aminophenol (PAP) and acetaminophen (Ac) was studied, and the results demonstrated that the CdS/CPE exhibited good electrocatalytic performance toward PAP and Ac oxidation. The oxidation peak potential of each analyte in the mixture was well separated. As a result, a selective and reliable method was developed for the determination of PAP and Ac simultaneously without any chemical separations. Application of the fabricated electrode for monitoring the process of Ac preparation from PAP was investigated. The obtained results show that CdS/CPE has satisfactory analytical performance; it could be a kind of attractive and promising nanomaterial-based sensor for process monitoring via the electrochemical approach. © 2016 Elsevier Inc.
