Impact of Surfactant on the Retention of CO2 and Methane in Carbonate Reservoirs
(
American Chemical Society
, 2018 , Article)
Enhanced gas recovery methods such as foamed CO2 are recommended for depleted gas reservoirs. Viscoelastic surfactant (VES) is a form of a surfactant used for forming CO2 foam. In this study, the impact of VES on CH4 and ...
Piezoresponse, mechanical, and electrical characteristics of synthetic spider silk nanofibers
(
MDPI AG
, 2018 , Article)
This work presents electrospun nanofibers from synthetic spider silk protein, and their application as both a mechanical vibration and humidity sensor. Spider silk solution was synthesized from minor ampullate silk protein ...
Molecular Modeling Study toward Development of H2S-Free Removal of Iron Sulfide Scale from Oil and Gas Wells
(
American Chemical Society
, 2018 , Article)
A common problem that faces the oil and gas industry is the formation of iron sulfide scale in various stages of production. Recently an effective chemical formulation was proposed to remove all types of iron sulfide scales ...

(
Wiley-VCH Verlag
, 2018 , Article Review)
In this paper, organic-based capacitive and resistive humidity sensors, starting from the fundamental working principles, designs, and characterization, are reviewed. The prevalent adoptions of recent technology in the ...
Recent advances in electroless-plated Ni-P and its composites for erosion and corrosion applications: a review
(
Springer Nature
, 2018 , Article Review)
The metallic coating of surfaces plays a vital role in the protection of most industrial applications. Coatings can be carried through various routes (e.g., mechanical and electrochemical plating techniques). Electroless ...
The missing piece of the puzzle regarding the relation between the degree of superhydrophobicity and the corrosion resistance of superhydrophobic coatings
(
Elsevier Inc.
, 2018 , Article)
This work supplies the missing piece of the puzzle regarding the unclear relation between the water contact angle (WCA) of a superhydrophobic coating (SHC) and its corrosion protection performance. Generally, an increase ...
Multi-component MWCNT/NG/EP-based bipolar plates with enhanced mechanical and electrical characteristics fabricated by compression moulding
(
Elsevier Ltd
, 2018 , Article)
In this work, multi-walled carbon nanotubes (MWCNTs), natural graphite (NG) and epoxy (EP) were used to fabricate bipolar plates by the compression moulding technique. The mechanical and thermal behaviours of the as-developed ...
Gelation of Emulsified Polyacrylamide/Polyethylenimine under High-Temperature, High-Salinity Conditions: Rheological Investigation
(
American Chemical Society
, 2018 , Article)
Emulsified gels are proposed as a method of water shut-off in oil and gas reservoirs and are designed to separate into a water phase and an oil phase under reservoir conditions. A first of its kind rheological study on the ...
Evaluating the effect of seasonal variations on walking behaviour in a hot weather country using logistic regression
(
Routledge
, 2018 , Article)
The city of Doha, Qatar experiences a hot and arid weather throughout the year. This study investigates the effect of season, type of day, and time of day on the walking behaviour of pedestrians in these conditions using ...
