Analytical methods for nanomaterial characterization

Abstract: In recent years, it has become evident that it is necessary to systematically and accurately define particle characteristics in order to understand the potential toxicity of nanoparticles to biological systems. The properties that need to be emphasized are size, shape, dispersion, doping, aggregation, functionalization, physical and chemical properties, surface area, and surface chemistry. Route of exposure are Oral, dermal, inhalation and injection. Toxicity screening strategy; In Vitro Assays, In Vivo Assays and cell type are also an important parameter to consider while studying the toxicity of nanoparticles. These analytical methods used to check the toxicity require expensive equipment and sampling, which are time consuming. Using the bacteria, as a biosensor, solves these problems. This method is sensitive, low-cost and easily reproducible and takes 5 to 30 minutes to predict toxicity. This review focuses to develop a synergy among different paradigm of Nanomaterials characterization.

TIVA C Series Based Smart Power Analyzer

Abstract: This paper describes about the analysis of various signal characteristics which is an extended version of oscillogram for utility grid with advanced resources. The main aim of this design is to reduce the cost of manufacturing and the size of the instrument and works on low power. In this smart analyzer it is capable of monitoring the real time parameters and recording of various electrical parameters such as voltage, frequency, power active and reactive by using signal processing technique such as fast Fourier transform (FFT). we measure FFT voltage, FFT current and disturbance on voltage and the results are shown in a graphical dashboard.

3- (2-(Trifluoromethyl)phenyl)hydrazono pentane-2,4-dione

Abstract: The crystal structure of the title compound, C12H11F3N2O2, is stabilized by one N—H⋯O and two N—H⋯F intra­molecular hydrogen bonds, and by one C—H⋯F and two C—H⋯O inter­molecular hydrogen bonds. These hydrogen bonds generate R44(13)S(6)S(6)S(6)R33(20) ring motifs in the ac plane. Except for four H atoms of the methyl groups and two F atoms of three trifluoromethyl groups, all atoms are almost in the same plane, and the N—N=C—C(OCH3) torsion angles are 4.1 (3) and −175.25 (14)°.
