The modification in oxidation state of polyaniline when it was doped with anthracene was studied through UV-VIS Absorption studies and FTIR measurements. UV-VIS absorption studies indicated that with increasing dopant concentration the intensity of absorption at 600 nm increases. This is attributed to the change in population of quinoid imine units in the polymer backbone. Two significant changes were observed in the FTIR spectrum of bare and doped polyaniline. First is appearance of a peak at...

Ac conductivity in the frequency range of 5×103 to5×103 Hz of Phthalocyaninato Aluminum Chloride (PcAlCl) was measured, which consists of frequency dependent and independent parts. The Dc conductivity is attributed to the charge carrier’s transition, between valance and conduction bands, while the Ac conductivity is due to hopping of charge carriers, between the localized sites around Femi level which is an indication of degree of imperfection around Fermi level in the crystal lattice.The...

Life and water are linked closely as it is essential for life to begin and for life to live on. Water passes through soil and aquifers often come in contact with minerals which at the correct environmental conditions, dissolve in the ground water to make it hard. The high mineral content water is normally not dangerous to human’s health, but it causes many household problems which makes it less desirable. A physical technique using magnetic field to purify water is cheap, require no energy to...

Abstract — Coir pith is a byproduct of coir industry. It is dumped as an agricultural waste for a long period of time. Usually it is disposed by burning which may release lot of carbon into atmosphere causing air pollution. Coir waste has a high lignin and cellulose content. its carbon nitrogen ratio is around 100:1. Because of the high lignin content Left to itself, coir waste takes decades to decompose.Thus it is leached out during course of time due to rain in to water resources causing...

The resistances of an iron wire and a Pt-wire, wound on the same support and enclosed /b in vacuo/ in quartz glass, were compared at very short intervals of time during heating and cooling. Six iron thermometers were used from three samples, and all gave the same characteristics for pure iron. The resistance of iron increases from 0 degrees C. Without anomalies and with a gradually increasing temperature-coefficient until the neighbourhood of A1 is reached, As A2 is approached the resistance...

Measurement of soil components such as microbial population, minerals and obviously the content of organic carbon play the important roles for the productivity of crops and plants. The present study was attempted to evaluate the impact of Mr. Trivedi’s biofield energy treatment on soil for its physical (electrical conductivity), chemical (minerals) and microbial flora (bacteria and fungi). A plot of lands was assigned for this study with some already grown plants. This plot was divided into...

The goal of this SBIR project, which has completed Phase I and is in the process of starting Phase II, is the development of highly accurate, yet low-cost sensors for the measurement of oceanographic electrical conductivity, temperature, and depth (CTD). The project s initial focus is on developing an expendable device (XCTD). These low-cost XCTDs will affordably provide the greater utility of simultaneous, collocated conductivity and temperature profile measurements (as compared to just...

The passage from electrical super-conductivity to normal conductivity of metals at low temperatures may be attained with a critical current density or by the application of a critical magnetic field. The author regards these two means as interdependent. In a previous paper the case of a wire conveying a current was treated and the magnetic field resulting was such as to give rise to a central superconducting core with an outer resisting layer. This condition is unstable. The present note...

The electrical conductance of sodium chloride in glycerol-water mixture has been measured at 25 C to test the validity of the Fuoss-Onsager theory in the case of a mixture with viscosity varying in a very large range. With the mixture used as a solvent, it is possible to vary the viscosity by a factor of a thousand. For all the mixtures the concentration method has been used. For the solution in pure glycerol the dilution method has been used due to the high viscosity. The results show that the...
