Rheological characterization of NA2CO3 activated calcium bentonite for oil and gas drilling applications
( AIChE , 2015 , Conference Paper)Calcium bentonite was activated with soda ash (Na2CO3) at various ratios and due to the ion exchange; the original Ca-bentonite was converted to Na-bentonite. It was found that the Na2CO3 activation improves the swelling ... -
Rheological evaluation of shortand long-term performance for warm mix asphalt (WMA) binders
( Kluwer Academic Publishers , 2016 , Article)Warm-mix asphalt (WMA) additives are environmentally friendly and cost-effective products that lower the viscosity of bituminous binders to allow reduction of mixing and compaction temperatures in asphalt mix production. ... -
Rheological, Thermal, and Chemical Evaluation of Asphalt Binders Modified Using Crumb Rubber and Warm-Mix Additive
( American Society of Civil Engineers (ASCE) , 2022 , Article)This study evaluates the potential of producing warm-mix asphalt (WMA) using a wax-based additive (Sasobit) in a binder modified using crumb rubber (CR). This binder is formulated for very hot climates and has a grade of ... -
Rheological, Thermodynamic, and Gas Solubility Properties of Phenylacetic Acid-Based Deep Eutectic Solvents
( Wiley-VCH Verlag , 2017 , Article)Choline chloride + phenylacetic acid-based deep eutectic solvents are studied. Their most relevant experimental physicochemical properties at different mixing ratios together with the CO2 solubility data obtained in wide ... -
Rheology of organoclay assisted extrusion of HDPE using Particle Image Velocimetry
( Institution of Chemical Engineers , 2015 , Article)Wall slip is often seen as a source of flow enhancement and can play a significant role during certain melt instabilities in polymer processing. In the present investigation, the effect of organoclay on the wall slip of ... -
Rheology of Triamine Functionalized Silica Reinforced Polymeric Gels Developed for Conformance Control Applications
( American Chemical Society , 2020 , Article)Recently, cross-linked polymers such as polyacrylamide (PAM)/polyethylenimine (PEI) have been used in conformance control applications to replace conventional lost circulation materials (LCMs). The objective of this work ... -
Rheology of upstream complex fluids
( Elsevier , 2023 , Book chapter)Rheology is an important characterizing technique as it affects all types of fluids. While oil and gas recovery is an operation that depends mainly on the interaction between different fluids, it is therefore important to ... -
Rhus coriaria induces senescence and autophagic cell death in breast cancer cells through a mechanism involving p38 and ERK1/2 activation
( Nature Publishing Group , 2015 , Article)Here, we investigated the anticancer effect of Rhus coriaria on three breast cancer cell lines. We demonstrated that Rhus coriaria ethanolic extract (RCE) inhibits the proliferation of these cell lines in a time- and ... -
Rhus coriaria L. (Sumac) evokes endothelium-dependent vasorelaxation of rat aorta: Involvement of the cAMP and cGMP pathways
( Frontiers Media S.A. , 2018 , Article)Rhus coriaria L. (sumac) is widely used in traditional remedies and cuisine of countries of the Mediterranean as well as Central and South-West Asia. Administration of sumac to experimental models and patients with diverse ... -
Rhus coriaria suppresses angiogenesis, metastasis and tumor growth of breast cancer through inhibition of STAT3, NFκB and nitric oxide pathways
( Nature Publishing Group , 2016 , Article)Recently, we reported that Rhus coriaria exhibits anticancer activities by promoting cell cycle arrest and autophagic cell death of the metastatic triple negative MDA-MB-231 breast cancer cells. Here, we investigated the ... -
