L-asparaginato complexes of Copper(II), Zinc(II) and Cadmium(II) were synthesized from their respective metal oxide L-asparagine. These prepared characterized by content analysis, infrared, ultravioletvisible spectral studies, magnetic susceptibility measurement, thermal cyclic voltammetric measurement. Physico-chemical investigations reveal that [M(OOCCHNH2CH2CONH2)2], (M = Cu(II), Zn(II), Cd(II)) is the general formula for complexes. L-asparagine combines with oxides to form...
Abstract Lithium tungsten bronzes with a nominal composition of Li 0.4 WO 3 were synthesized by solid state reactions in silica tubes at 973 K and various low pressures. Samples characterized using X-ray single crystal powder diffraction, neutron diffraction. The air pressure inside the sealed quartz played roles for formation phases different symmetries. Whereas 10 –7 MPa pure body centered cubic ( Im <m:math xmlns:m="http://www.w3.org/1998/Math/MathML" display="block"> <m:mover...
The electrochemical redox behavior of Cu(II) has been investigated at glassy carbon electrode (GCE) in Britton-Robinson (BR) buffer as well a mixture BR and potassium chloride media. It is apparent that can act supporting electrolyte modify the ion aqueous medium. In medium, undergoes one two-electrons process, while KCl media it follows two one-electron reaction routes. Because formation hydrogen bridge bond between GCE surface, Cu(II)/Cu(0) path, presence such not formed successive...
ABSTRACT Solid complexes of tolfenamic acid (tolfH) with Mg(II), Ca(II), Sr(II), and Ba(II) have been synthesized characterized by CHN, metal contents analysis, FTIR, UV, 1 H‐NMR spectroscopy, thermal (TGA, DTG, DTA, DSC) molar conductance, powder X‐ray diffraction (XRD), scanning electron microscopy (SEM–EDX). Based on these studies, the probable formulae for are [Mg(tolf)Cl(H 2 O) 3 ].4H O, [Ca(tolf) (H ], [Sr (tolf) 4 [Ba ]. The ligand tolfenamate ion exhibited different modes...
Controlling the speed of a conveyor belt for variable loads is crucial any industrial application. Therefore, in this manuscript, simulation work proportional-integral-derivative (PID) controller-based DC motor-driven system presented. The procedure starts with selecting right model designated After specific rollers and other components selected, drive pull required to be calculated varying from no object on maximum allowable mass conditions. Based these power requirements, motor selected. A...
To cope with the uprising global demand of electricity, it is crucial to implement energy saving methods from consumer end. Increasing electricity production limited by availability fuel and other resources, which not a feasible approach without increasing efficiency system. This work proposes an method for air conditioning systems through controlling set temperature, can be implemented effectively reduce during peak hours in case response (DR) events. A responsive temperature control has...
Abstract Polycrystalline samples of tantalum and vanadium single double substituted hexagonal potassium tungsten bronzes (K-HTB’s) with nominal compositions K 0.3 (W 6+ 0.7 W 5+ 0.3–y Ta y )O 3 (0≤y≤0.3), V (0≤y≤0.18) y/2 (0≤y≤0.3) were synthesized by solid state reactions in quartz tubes at 10 –7 MPa 1073 K. The applied synthesis condition allowed WO to crystallize space group P 6 22, confirmed X-ray powder diffration Raman spectroscopic analyses. In this K-HTB composition, could fully be...
