----------------------------------------------------ABSTRACT----------------------------------------------------To control the steric interactions induced by disubstitution in the polythiophene and its derivatives a series of 3,4-disubstituted polythiophene derivatives have been described. In the present study the eff…
Extraction of Heliotropium curassavicum. Aerial parts resulted . The crude extract was evaluated for their antibacterial and antifungal activity. The results indicate that Ethyl acetate and methanolic extracts, exhibited significant antimicrobial activity.
Polarization in antiferroelectric liquid crystals has two origins: The piezoelectric polarization which is of chiral origin and the flexoelectric polarization which originates in different orientation of tilts in neighboring layers. The flexoelectric polarization is perpendicular to the tilt direction only if the stru…
Zinc Cadmium thiocyanate single crystal was grown from aqueous solution by slow cooling technique. The lattice parameters of the crystal have been obtained by single crystal X ray diffraction analysis. Kurtz-Perry test confirms the emission of green radiation from the sample thus exhibiting SHG. Thermal stability and…
This paper presents the effect of temperature on mechanical properties of reactive powder concrete (RPC) at elevated temperatures. The influences of temperatures, polypropylene (PP) fibre and steel fibre content, hold time, dimension of specimens and explosive spalling were investigated. The microstructure of RPC was…
CuO showed good efficiency towards the degradation of Methyl green dye in a wastewater sample. The process obeyed a first kinetics model and the results showed the best degradation rates at the following conditions: pH=6.5, dye concentration; 35 ppm.
Copper antimony sulfide, CuSbS2 nanoparticles have a large potential of being a good thermoelectric material because they are made up of earth abundant elements. Thermoelectric materials can convert thermal energy into electricity, so that the wasted energy can be saved. Also, by using this earth abundant material, we…
Samples from sheets of the polymeric material cellulose triacetate have been exposed to alpha particles in the dose range 20 - 100 Gy . The modifications induced in the molecular and optical properties of cellulose tri acetate samples due to a lpha particles irradiation have been studied through different characteriza…
a new species of Encyonema was found in several rivers and reservoirs in Western Pennsylvania, USa, in 2013. the new species, E. appalachianum , has only very slightly dorsiventral valves, which is one of the characters separating the genus Encyonopsis from Encyonema . on the other hand, the long, sharply bent termina…
Abstract Abstract Abstract Abstract Evaluation of different approaches to scale up PBMR (Packed Bed Membrane Reactor) for HI decomposition has been carried out using numerical simulations. Numerical simulations involve coupled solution of momentum, energy and species transport equations. The results suggest that, to p…
Parkinson’s disease is a debilitating neurological disorder characterized by selective and progressive degeneration of neurons in the substantia nigra pars compacta and by abnormal aggregation of α-synuclein. It is believed that cellular secretion of the protein fibrils or fibril precursors and subsequent endocytosis…
Hausmannite Mn3O4 nanorods were successfully prepared via solid- state thermal decomposition route with manganese(III) Schiff base complex (Mn(Brsal-mepn)(l1,3-N3))n as manganese source in air at 400 C for 4 h. Powder X-ray diffraction, Fourier transform infrared spectrometry and scanning electron microscopy were used…
Synthesis of Zn-Al-EDTA hydrotalcite and its application as adsorbent for Pb2+ ion have been studied. The aim of this research was to study the ability of Zn-Al-EDTA hydrotalcite as adsorbent of Pb2+ ion. Acidity condition, kinetics, and adsorption capacity along with characterization of Zn-Al-EDTA hydrotalcite solid…
Single and bi-layer thin films of LaMnO3 and La0.67Ba0.33MnO3 were deposited on amorphous fused silica substrate via pulsed laser deposition technique (PLD). In this work, the effect of stacking sequence in bi-layer manganite films of LaMnO3 and La0.67Ba0.33MnO3 was reported. The crystal structure formation, magnetic,…
Corrosion behavior of pure Al and Al/ Al 2O3 composite with five weight percent of Al 2O3 particles (5,10,15,20 and 25) were investigated in 0.1M H 2SO4 and 3.5 % NaCl solutions at room temperature. The composites were prepared by powder metallurgy and their corrosion behavior were evaluated by potentiostatic polariza…
Polypropylene/Multiwall carbon nanotubes/Montmorillonite (PP/MWNTs/MMT) hybrid nanocomposites were prepared by using twin-screw extruder incorporating the polypropylene grafted maleic anhydride (PP-g-mA) as compotibilizer is used for better dispersion of nanoclay in the polymer matrix. The effect of MWNTs and MMT on t…
Statistical analyses of three probability density functions, from Normal, Rayleigh and Weibull distributions, were applied for studying steel-rebar corrosion risk/probability in inhibitor admixed steel-reinforced concrete immersed in aggressive media of 3.0% NaCl and 0.5 M H2SO4. For these, different concentrations, r…
