fluid properties with constant improvement in efficiency have been noticeable as important criteria in drilling operation. the main drilling fluid properties highly depend on utilization of new polymers with high efficiency in drilling fluid composition. in this paper, the performance of a new polymer, called partially hydrolyzed polyacrylamide polymer (phpa), is studied which has recently ente...
Grazing Incidence Small-Angle Scattering (GISAXS) is a valuable experimental technique in probing nanostructures of relevance to polymer science [1]. Experimentalists are expressing a growing need for efficient and scalable simulation tools to dissect the massive volume of GISAXS data gathered at stateof-the-art beamlines. New high-performance computing algorithms, codes, and software tools hav...
A power conversion efficiency of 9.02% is obtained for a fully solution-processed polymer tandem solar cell, based on the diketopyrrolopyrrole unit polymer as a low bandgap photoactive material in the rear subcell, in conjunction with a new robust interconnecting layer. This interconnecting layer is optically transparent, electrically conductive, and physically strong, thus, the charges can be ...
the present research study attempted to find out the extent to which two pre-task activities of “glossary of unknown vocabulary items” and “content related support” assisted efl language learners with their performance on listening comprehension questions across two different proficiency levels (low and high). data for this study were obtained from a total of 120 language learners, female and m...
in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
Introduction:Acidic sludge is a by-product of used motor-oil reprocessing industries which is disposed of in the environment as hazardous waste material. The polymer bitumen under certain conditions is produced from mixing Bentonite soil, polymer styrene - butadiene – styrene(SBS) and acidic sludge.The aim of this study was retrieval of acidic sludge from polymer bitumen using additives such a...
Background & Aims: In this study, a magnetic molecular imprinted polymer was used to measure the diltiazem drug. Based on the structure and pharmaceutical agent group, methacrylic acid was selected as a monomer for Diltiazem. Ethylene glycol de-methacrylate and azobisisobutyronitrile were used as cross-linkers and polymerisation initiators, respectively. Also, chloroform was used as a porogenic...
