Two nine-coordination coordination polymers of neodymium, [Nd2(p-C8H4O4)(o-C8H4O4)2 • 4H2O] n (I), [Nd2(C10H4O8)(C10H2O8) • 2H2O] n (II), have been prepared by hydrothermal reaction of Nd(NO3)3 • 6H2O with terephthalic acid and phthalic acid, or benzenetetracarboxylic anhydride and determined by means of IR, UV, fluor…
In this paper; a new hybrid three phase four wire dynamic static compensator (3P4W DSTATCOM) is proposed for compensation of phase current harmonics; reactive power and neutral line current in three-phase four-wire electrical distribution system (3P4W). The proposed hybrid 3P4W DSTATCOM is consists of a neutral line c…
In the last few decades, energy storage systems (ESS) have become a major research area in electric, hybrid-electric, and plug-in hybrid electric vehicles (EVs, HEVs, and PHEVs) [1]. ESS mainly consists of a battery and ultra-capacitor (UC) connected together to build a system with high energy and power that can provi…
Radial flux PMBLDC motors are designed using CAD program. CAD program gives dimensions and performance of the motor and compared with finite element analysis result to validate the design. Radial flux PMBLDC motor having only one major disadvantage that is cogging torque. Cogging torque cause due to interaction betwee…
Rogers Ratio Method (RRM), Duval Triangle Method (DTM), IEC Ratio Method (IRM) (Basic Gas Ratios Method) and GB/T 7252 (National Standard of the People's Republic of China) are popular conventional methods for interpreting the possible faults indicator of transformer. Each of them has its own characteristics and these…

Metal Oxide Varistors (MOVs) are widely used in power distribution networks and electric loads and appliances in order to protect against lightning surges and transients overvoltages. Degradation and failure of the MOVs due to lightning surges are one of the concerns of surge protection designers that usually lead to…
Power transformers play a very critical role in electrical energy transmission. Abnormal performance of transformers would seriously affect the reliability and stability of power system. Non-electrical gas relays are usually used as a main protection of power transformers. Indeed, due to the inherent defects, the gas…
New technological procedure for obtaining spherical carbon sorbents was considered. The method is based on oil granulation in the technology of coal benefication. The coal dust of 2SS brand and coal tar were used to obtain spherical activated carbons with high sorption and strength characteristics. The influence exert…
The possibility of applying the method of microwave synthesis for the fabrication of nanosized particles of complex oxides has been demonstrated. The effect of fabrication conditions on the size of nanoparticles with a garnet structure has been established on the example of the Gd–Ga–Al–O system. The concentration of…
Streaming electrification has been identified as one of the main failure reasons for large power transformers. Different measurement methods including pipe flow method, rotating disk method and mini-static tester have been proposed to investigate this phenomenon. In this paper, a small scale laboratory based pipe flow…
A procedure has been proposed for the direct synthesis (without the use of reductants) of silver nanoparticles in an epoxy polymer matrix with the formation of novel nanocomposites. The average size of the formed nanoparticles has been shown to be about 18 nm. The polymer cross linking leads to the formation of chain…
Compression garments are special textile products which apply a pressure on needed body zones for supporting medical, sport or casual activities. Medical bandages are a group of these garments and they have a very common usage for compression effect on legs or arms. These bandages are generally produced by using synth…
Huge interests in usage of organic carbon in preparing counter electrode for DSSC have increased extensively among the researchers. Compositeelectrode using hydrocarbon of Dammar (Canarium strictum) (D) and Iron (III) Oxide Carbon nanoparticles (Fe2O3) were prepared as counter electrode (CE) for DSSC evaluation. Damma…
Abstract Three porous uranyl complexes {(CH 3 ) 2 NH 2 [(UO 2 )(L 1 )]⋅H 2 O} n (1) , {[(UO 2 ) 5 ( μ 2 ‐OH)( μ 3 ‐OH)(L 2 ) 2 (H 2 O) 3 ]} n (2) and {[(UO 2 ) 4 ( μ 3 ‐OH) 2 (L 3 *) 3 ]} n ( 3 ), { H 3 L 1 = 5‐((4‐carboxybenzyl)oxy)isophthalic acid, H 4 L 2 = 4,4’‐oxydiphthalic acid, and H 2 L 3 = 4,4’‐((6‐chloro‐1,3…
Abstract Thin films of Nafion of various thickness viz . 6 and 1 µm, 280, 80 and 33 nm have been probed using the fluorescent molecule 2‐(2′‐pyridyl)benzimidazole (2PBI), at low as well as high hydration levels. The acidity of these films has been found to be less than that of Nafion 117 membrane at hydrated condition…
Melt compounding of polylactide with ductile polymers is widely proposed as an efficient alternative to overcome its inherent brittleness. An ethylene alkyl acrylate is used as toughening modifier of polylactide. A two‐phase morphology is detected by melt blending of Polylactide and Biomax Strong. Furthermore, the eff…
Electrical switching with an S-shaped I–V characteristic is studied in metal/oxide/metal structures based on vanadium oxide thin films fabricated by electrochemical oxidation. This switching effect is associated with the metal–insulator phase transition in VO2, and the channels consisting of vanadium dioxide are forme…
LaMgAl11O19 was synthesized at 1550 °C using La2O3, MgO and Al2O3 as raw materials. The samples were characterization by XRD and SEM. The tablet shaped crystals free of impurity phase formed under this condition. The thermal diffusivities were measured by laser flash method and the determined intrinsic thermal conduct…
