Effect of Sintering Temperature on Current-Voltage Characteristics of Nanostructured Manganites
Abstract: Normal 0 false false false EN-IN X-NONE GU MicrosoftInternetExplorer4 In the present communication, nanostructured Y0.95Ca0.05MnO3 manganites using low cost sol-gel method have been synthesized. Samples were sintered at different temperatures in order to change the particle size of the samples. The crystallite size is found to increase with sintering temperature due to crystal agglomeration effect. To understand the transport properties of the presently studied samples, current-voltage (I-V) characteristics have been …

Voltage-controlled TCR (Temperature Sensitivity) in Nanostructured Y0.95Ca0.05MnO3/Si, p-n Junction Diode
Abstract: The authors deposited a p-type Y0.95Ca0.05MnO3 on the n-type Si substrate using chemical solution deposition and form nanostructured Y0.95Ca0.05MnO3/n-Si, p-n junction diode with typical thickness of about 100 nm with polycrystalline in nature. The diode exhibits rectifying properties over the temperature range of 100–300 K. Voltage-dependent temperature sensitivity of Y0.95Ca0.05MnO3/n-Si, p-n junction diode has been studied in current perpendicular to film plane (CPP) geometry. The maximum percentage of TCR values …

Characterization and Stability Study of Synthesized Gold and Silver Nanoparticles
Abstract: A basic initial characterization and stability study of synthesised gold and silver nanoparticles was carried out. Silver nanoparticles were synthesised by modified Creighton's method. Gold nanoparticles were synthesised by Turkevich method. The synthesised nanoparticles were subjected to characterization studies using DLS, UV-VIS spectrophotometer, pH meter, and the size characterization was studied using Mie plot and NNLs software. The objective of the study being to check the stability of the nanoparticles …

Studies on Cr (VI) Removal from Aqueous Solution using Al2O3 and ZnO Nanoparticles Composite
Abstract: Cr (VI) is a heavy metal and is considered to be toxic both to environment and human beings after a permissible limit. The removal of Cr (VI) using conventional methods was ineffective. With introduction of nanotechnology, the remediation of Cr (VI) has become more easy and effective. Nanoalumina has been an efficient adsorbent system for the adsorption of different heavy metals. It has an excellent adsorption capacity for metal ions …

Minimizing the Synthesis Time of Nanostructured Powders in Planetary Mills using Biogeography-based Optimization (BBO) Algorithm
Abstract: A key objective in processing of nanostructured powders via high-energy ball milling is to minimize the synthesis time. This paper presents the application of biogeography-based algorithm for optimization of milling parameters in order to minimize the synthesis time of nanostructured powders in planetary mills. At first a direct relationship between the inverse of the milling time and the power of the planetary mill was established, which allows the validation of …
