Experimental and theoretical studies on the mechanical and structural changes imposed by the variation of clay loading on poly(vinyl alcohol)/cloisite 93A nanocomposites
(
John Wiley and Sons Ltd
, 2019 , Article)
Polymer nanocomposites (PNC) structures are promising materials due to their novel properties. However, many of their characteristic physical, mechanical, and chemical behavior have not been quantified. Depending on the ...
Thermochemical Upgrading of Calcium Bentonite for Drilling Fluid Applications
(
American Society of Mechanical Engineers (ASME)
, 2019 , Article)
The rheological properties of bentonite suspensions depend on the chemical composition and the contained dominant element, such as calcium (Ca), potassium (K), and sodium (Na). Na-bentonite type is the one used in drilling ...
Distinguishing characteristics and usability of graphene oxide based on different sources of graphite feedstock
(
Academic Press Inc.
, 2019 , Article)
Graphene oxide (GO) has gained popularity in scientific research and industry due to its superior properties, which can be controlled by the synthesis method and graphite feedstock. Despite the availability of different ...
Reaction kinetics of carbon dioxide in aqueous blends of N-methyldiethanolamine and L-arginine using the stopped-flow technique
(
MDPI AG
, 2019 , Article)
Reduction of carbon dioxide emission from natural and industrial flue gases is paramount to help mitigate its effect on global warming. Efforts are continuously deployed worldwide to develop efficient technologies for CO ...
Upgrading Calcium Bentonite to Sodium Bentonite Using Seawater and Soda Ash
(
American Chemical Society
, 2019 , Article)
In this paper, a new method is introduced to produce sodium bentonite by treating calcium bentonite using seawater to eliminate the use of freshwater and reduces the amount of soda ash required for the treatment, which ...
An Investigation of the Swelling Kinetics of Bentonite Systems Using Particle Size Analysis
(
Taylor and Francis Inc.
, 2019 , Article)
Particles size distribution (PSD) is introduced as a tool for analysis of bentonite aggregation and swelling kinetics. Raw Ca-bentonite was purified using a combined wet sieving and sedimentation processes, followed by ...
Molecular dynamics and combined docking studies for the identification of Zaire ebola virus inhibitors
(
Taylor and Francis Ltd.
, 2019 , Article)
Ebola virus (EBOV) is a lethal human pathogen with a risk of global spread of its zoonotic infections, and Ebolavirus Zaire specifically has the highest fatality rate amongst other species. There is a need for continuous ...
Adsorption kinetics and modeling of H2S by treated waste oil fly ash
(
Taylor and Francis Inc.
, 2019 , Article)
Waste oil fly ash (OFA) collected from disposal of power generation plants was treated by physicochemical activation technique to improve the surface properties of OFA. This synthesized material was further used for potential ...
Investigation of the rheological properties of nanosilica-reinforced polyacrylamide/polyethyleneimine gels for wellbore strengthening at high reservoir temperatures
(
American Chemical Society
, 2019 , Article)
Wellbore strengthening has been introduced recently to resolve lost circulation problems by improving the fracture gradient and hence extending the mud window. Polymeric cross-linkable solutions showed outstanding strength ...
Enhancement of CO2 biofixation and lipid production by Chlorella vulgaris using coloured polypropylene film
(
Taylor and Francis Ltd.
, 2019 , Article)
Chlorella vulgaris was cultivated with light at different wavelengths (λmax) and irradiation intensities (I) by applying a coloured tape (CT) as a simple, inexpensive light filter. C. vulgaris was cultivated in a standard ...
