In existing techniques solubility of conducting component is an essential condition. Reported technique facilitates making composite of conducting polymer, which is insoluble in normal solvents, with percolation threshold of 0.5 wt%. <span style="mso-ansi-language:EN-IN">Mechanism of formation of the three component hybrid may be described as when silica <span style="mso-ansi-language: EN-IN">which acted as seed is dispersed in insulating polymer, the in-situ polymerized conducting polymer having high aspect ratio is grown over the silica surface connecting each other and making a continuous network. The star like growth of the conducting polymer can be seen under optical microscope. </span></span> Page(s): 68-72 Fri, 01 Feb 2013 00:00:00 GMT http://nopr.niscpr.res.in/handle/123456789/16157 2013-02-01T00:00:00Z http://nopr.niscpr.res.in/handle/123456789/16156 Title: <span style="font-size:15.0pt;mso-bidi-font-size: 16.0pt;font-family:"Times New Roman";mso-fareast-font-family:"Times New Roman"; mso-ansi-language:EN-US;mso-fareast-language:EN-US;mso-bidi-language:AR-SA; mso-bidi-font-weight:bold" lang="EN-US">Modelling and optimization of mechanical behaviors of Al₂O₃-coir-polyester composites using response surface methodology</span> Authors: Sathiyamurthy, S; Thaheer, A Syed Abu; Jayabal, S Abstract: <span style="font-size:9.0pt;mso-bidi-font-size:10.0pt" lang="EN-US">The tensile, flexural, impact and abrasion loss behaviors of Al₂O₃impregnated coir fiber-reinforced polyester composites are evaluated. The short untreated coir fibers are used as reinforcements in polyester matrix. The effects of fiber length, fiber diameter and filler content on the mechanical properties of alumina-coir-polyester composites are studied by developed regression models in this investigation. The optimum parameters for better mechanical properties are determined using response surface methodology approach. </span> Page(s): 59-67 Fri, 01 Feb 2013 00:00:00 GMT http://nopr.niscpr.res.in/handle/123456789/16156 2013-02-01T00:00:00Z http://nopr.niscpr.res.in/handle/123456789/16155 Title: An experimental investigation of performance, combustion and emission characteristics of mahua (Madhuca Indica) oil methyl ester on four-stroke direct injection diesel engine Authors: Solaimuthu, C; Senthilkumar, D; Ramasamy, K K Abstract: This paper is mainly concerned with an experimental investigation to study the diesel engine performance, combustion and emission characteristics using mahua (Madhuca Indica) biodiesel (mahua oil methyl ester) and its blend in different volumetric proportions with diesel. To start with, the thermo-physical properties of all the fuel blends are evaluated. A four stroke tangentially vertical (TV) single cylinder direct injection (DI) diesel engine with eddy current dynamometer is used for the study under various load conditions. Combustion and emission characteristics for different blends are evaluated in running the engine under steady state conditions. Neat diesel is called B0 and neat (mahua oil methyl ester) biodiesel is called B100. From the experiments, it is seen that B25 gives almost the same brake thermal efficiency as B0 at full load condition, compared to other blends. The blend B0 and B25 give the lowest specific fuel consumption of 0.56 and 0.27 kg/kW.h at no load and full load as compared to all other blends. At no load B100 gives the lowest NO_x emission which is 2.52% less compared to B0.

The capacitor in the floating inductor simulator is grounded, which provides suitability for integrated circuit fabrication. However, it needs resistive matching conditions. The passive inductor of a series R-L-C voltage-mode filter is replaced by the present floating inductor simulator to give an application example. In order to show performance, theoretical findings are supported via a number of SPICE simulations and some experimental measurements.
