An inorganically template metaphosphoric acid containing copper salt, nanomaterial, has been synthesized and characterized with different measurement techniques such as Differential Scanning Calorimeter (DSC), UV-Vis-NIR, HRTEM, VSM, PPMS and X-RD. The thermal property of this salt has been studied at a low temperature up to 223 K from 298 K with DSC. The specific heat capacity of this complex has been measured in atmospheric O2 at a rate of 10 K min-1 from 298 K to 223 K and vice versa in two thermal cycles. The net specific heat capacity of this salt is found -88.28 J/gm.K and - 86.56 J/gm.K in first and second thermal cycles, respectively. There is a discontinuity in the specific heat at 106 s while measuring the specific heat capacity of the above nanomaterial at constant temperature 283 K. This particle size of this nanomaterial is ∼ 10 nm. The paramagnetic Curie temperature (θP) and Curie constant (C) are 18.29 K and 1.35x10-3 respectively. This material founds insulator from PPMS and UV-Vis-NIR measurements. So, it can be used as thermal interface material as a composite component with some organic polymers such as paraffin wax, ethylene-vinyl acetate etc. © 2016 Author(s).

Two inorganic mixtures of copper and sodium compounds have been synthesized and characterized with different measurement techniques. The thermal property of these mixtures has been studied to low temperature up to 223 from 573 K with DSC. The specific heat capacity of this mixture has been measured in atmospheric O2 at a rate of 10 K min−1 from 573 to 223 K and vice versa in two thermal cycles. The net specific heat capacity of these mixtures is found endothermic in first and second thermal cycles. The net specific heat capacity of 0.5Cu2(PO4)(OH); 3.5CuH(PO4)2·H2O; 2NaHSO4·H2O (CuPHS) during first thermal cycle is −71203.05 J kg−1 K−1 and in second thermal cycle is −73881.67 J kg−1 K−1 between temperature range of 303–223 K. The net specific heat capacity of mixture 0.5Cu2(PO4)(OH); 3.5CuH(PO4)2; 2Na2SO4(CuPS) in first thermal cycle is −21158.37 J kg−1 K−1 and in second thermal cycle is−45739.92 J kg−1 K−1 between temperature range of 298–573 K. As both mixtures are endothermic in nature in all cycles, it can be used as heat storage material.The average crystallite size of mixture 0.5Cu2(PO4)(OH); 3.5CuH(PO4)2·H2O; 2NaHSO4·H2O and 0.5Cu2(PO4)(OH); 3.5CuH(PO4)2; 2Na2SO4 is ~47 and ~17.3 nm, respectively. © 2016 Springer Science+Business Media New York

Substitution reactions of complex [PtI(dien)] + (where, dien=diethylenetriamine ) with sulfur-containing peptide l-cystine has been studied in 1.0 × 10 -1M aqueous perchlorate or acetate medium between 298 ≤ T (K)≤323 and 2.30 ≤ pH ≤ 4.45 using a UV-visible spectrophotometer. Products obtained have characterized from their physico-chemical and spectroscopic methods at various pH and temperatures. From this characterization, products have indicated that [PtI(dien)] + has formed a complex with l-cystine and acts as a bidentate ligand, through Pt-S bond at 2.30 ≤ pH ≤ 3.30 and through Pt-N and Pt-S bond of cystine in 3.95 ≤ pH ≤4.45. At 2.30 ≤ pH ≤3.30, ring opening and closing of dien have occurred at 308 and 323 K, respectively, and the same has happened at pH ≤ 3.95. All reactions have followed the rate law - d[mixture]/dt=(k 1+k 2 [cystine]) [Pt(II)], where k 2 denotes the second-order rate constant. Activation parameters E a,Δ H# and ΔS# have been determined. Product formation and reversible and forward reaction rate constants have also been evaluated. © 2010 Taylor & Francis.

Substitution reactions of the complex [Pt(dien)H 2O] 2+ (where dien = diethylentriamine or 1,5-diamino-3-azapentane) with sulfur-containing L-cystine have been studied in a 1.0×10 -1 mol dm -3 aqueous perchlorate medium at various temperatures (298-323 K) and 4.45≤pH≤2.15 using UV-vis spectroscopy. The products obtained have been characterized by their infrared and 1H NMR datasets at various pH levels and temperatures. From infrared and 1H NMR data, products have indicated that [Pt(dien)H 2O] 2+ reacted with L-cystine forming a Pt-S bond at low pH. At high pH, a product complex through the Pt-N bond has been formed. All rate constants have been evaluated from nonlinear double exponential plots. The activation parameters ΔH# and ΔS# have been determined using the Eyring equation. The products, SNi, and reversible rate constants have been evaluated.

An inorganically template metaphosphate of Co(II) complex has been synthesized and thermal properties have been studied at a low temperature up to 173 K from 298 K by the Differential Scanning Calorimeter (DSC). The specific heat capacity is measured in atmospheric O 2 at a heating rate of 283 Kmin -1 from 298 K and kept constant at 173 K for 4 minutes then reversed to 298 K again. The bulk critical temperature of superconductivity of metaphosphatecobalt( II) salt was found at 173 K. © Springer Science+Business Media, LLC 2012.

A new inorganically template metaphosphate of Co(II) complex has been synthesized and characterized by different measurements such as DSC, FT-IR, C-H-N-O-S, ESR, TG-DTA and X-RD. Differential Scanning Calorimeter (DSC) elucidated negative specific heat of the system and has used to evaluate some thermo dynamical constants like activation energy (E a), frequency factor (A), enthalpy and entropy of that system. The specific heat capacity of the system is measured both in atmospheric O 2 and N 2 atmosphere at different heating rates of 278, 283, 293 and 298 K min -1 in room atmosphere and 288 K min -1 in N 2 atmosphere. © 2010 Akadémiai Kiadó, Budapest, Hungary.

Post-war telecommunications network is completely damaged by aerial bombings as mostly towers and elevated structures are bombarded. This brings hindrances to the postwar information retrieval as it becomes extremely difficult to communicate using the previously established communication system. The aim of this paper is to fabricate a MANET based emergency communication system containing Damage Assessment Subsystem, Data Processing Subsystem and a Data Localization Subsystem. Apart from theoretically formulating the Post-War Information Retrieval System (PWIRS), this paper focuses on collaborative information gathering and independent processing of data through the MANET based networking infrastructure. © 2015 IEEE.

The kinetics of the oxidation of L-cystine by the di-oxo-bridged Co(III) complex have been studied at various temperatures, 298 K to 323 K, and pH, 3.30 to 4.45, using UV-vis spectroscopy in NaClO4 medium.
