Today's high functionality electronic circuits require faster interconnection speed, better thermal conductivity and the good mechanical properties for reliability. These requirements calls for enhanced properties of the present solder materials. Appropriate reinforcements in the existing solder material will help in achieving much improved electrical, mechanical and thermal properties. Carbon Nano...
In the present work, we report the room temperature NH3 sensing properties of Cobalt-boride nanoparticles intercalated polyaniline (Co-B-PANI) nanocomposite films. Polyaniline nanocomposite films (PNCF's) have been deposited at room temperatures by in-situ oxidative polymerization of aniline in the presence of Co-B nanoparticles. The PNCF exhibited a highly selective, sensitive and reversible response...
The paper presents Tin oxide (SnO2) based low cost, high temperature operable resistive type low humidity (10–20%RH) sensor. SnO2 thin films were prepared by spin coating 50 μl of synthesized (SnCl2) solution on alumina substrate (1.44 cm2). Material characterization of the synthesized material was carried out using UV-Visible, SEM and XRD. To get films of higher thickness they were coated from 1...
Cadmium zinc oxide (CdXZn1−XO) thin films were deposited at low substrate temperature using advanced spray pyrolysis technique. Aqueous solution of cadmium acetate and zinc acetate were used as initial ingredients. The films were prepared by keeping optimized preparative parameters constant. Influence of variation of zinc in the ‘CdXZn1−XO’ system on the structural, electrical and gas sensing properties...
Electro-chemical discharge machining (ECDM) is a recent technique used to machine insulating materials like glass and ceramics. This paper presents the results of the combined effects of tool feed-rate and tool shape on the micro-machining of a quartz substrate using an ECDM process. The investigations show that a tool with a spherical tip provides a profile with a reduced entrance diameter and the...
Zinc oxide (ZnO) nanorod arrays were deposited on to the soda-lime glass substrates by wet chemical route using zinc acetate as precursor. The structural and surface morphological properties of the ZnO nanorod arrays (ZNAs) were investigated by X-ray diffraction (XRD), and scanning electron microscopy (SEM) respectively. The XRD pattern revealed wurtzite crystal structures of ZNAs, preferentially...
In this work, the annealing effects of e-beam deposited Ta2O5 films on the pH sensitivities of EIS based sensors are presented. XPS studies confirmed that the films annealed above 700 °C showed the best stoichiometry (Ta1.96O5.04) compared to the as deposited film and the films annealed till 600 °C. XRD spectra confirmed the amorphous nature of the as deposited film, which remained amorphous till...
In the present work, a commercial device for the detection of H2S using SnO2; CuO thin film as a sensing material has been demonstrated. A complete device consist of SnO2: CuO sensor thin film deposited on alumina substrate, teflon head in stainless steel housing containing the temperature control circuit with Pt-50 based heater and Pt-100 as reader, and a stand-alone monitor consisting of Data Acquisition...
The present paper reports room temperature operable LPG sensor based on Fe2O3-PdOdoped SnO2 thin films. Thin films were deposited by spin coating and were fired at an optimized temperature of 550°C. Single step thermal decomposition is used to get SnO2 films. The obtained films showed response from 100 to 2520 ppm of LPG. The films were characterized by XRD and UV-Vis spectroscopy. The average particle...
