Any improvement in drilling technology is critical for developing the oil and gas industry. The success of operations largely depends on fluid characteristics. Drilling fluids require enough viscosity to suspend particles transport them surface capability control loss into formation. Rheology filtration characteristics are crucial factors consider while ensuring effectiveness a operation. Graphene oxide (GO), xanthan gum (XG), low-viscosity carboxymethyl cellulose (CMC LV) being utilized...
Catalytically graphitized electrospun carbon nanofibers were plated with nickel using a commercial electroless bath for the first time. The nanofiber fabrication process was performed in presence of as graphitization catalyst at temperature 1400 °C. Raman spectroscopy and X-ray diffraction studies confirmed achievement satisfactory degree nanofibers. After sensitization activation processes, submerged 20 min 45 °C pH value 9. Results from scanning electron microscopy showed that pure,...
A combination of the remarkably simple technique electrospinning, developed to fabricate polymer nanofibers, and sol–gel processing has been utilized produce fine zinc oxide nanofibers with an average diameter 70 nm. non-toxic precursor solution polyvinyl alcohol acetate was electrospun resulting fibers were then calcined at a relatively low temperature ZnO nanofibers. Simultaneous thermal analyses used study formation from material. X-ray diffraction employed analyze phases different...
In this study, polyvinylidene fluoride (PVDF) membranes with various structures ranging from dense to highly asymmetric morphologies were obtained by changing the effective parameters in phase inversion process. The effect of some important processing such as solution concentration, harshness precipitation bath, exposure time before immersion coagulation bath and temperature was studied mentioned optimized. then modified nano-sized alumina powder order improve hydrophilicity PVDF membranes....
Effects of buffer salt concentration on the rate deposition, dominated deposition mechanism and subsequently structural, morphological, optical properties cadmium sulfide (CdS) thin films deposited by chemical bath (CBD) glass substrate were investigated. The precursors chosen to be chloride (CdCl 2 ) as source, thiourea (CS(NH[Formula: see text]) sulfur ammonium nitrate (NH 4 NO 3 ammonia complexing agent pH controller. influence NH structure, morphology, film uniformity, stoichiometry CdS...
Catalytically graphitized electrospun carbon nanofibers adorned uniformly with fine nickel nanoparticles were successfully prepared. The procedure was based on the electrospinning technique and use of precursor to create both under a relatively low-temperature heat treatment. X-ray diffraction Raman results clearly proved catalytic graphitization polymer-based fibers in presence catalyst. Taking from scanning transmission electron microscopies into account, it inferred that during treatment,...
