Benchmarking the Self-Assembly of Surfactin Biosurfactant at the Liquid–Air Interface to those of Synthetic Surfactants
(
Springer-Verlag
, 2016 , Article)
The adsorption of surfactin, a lipopeptide biosurfactant, at the liquid–air interface has been investigated in this work. The maximum adsorption density and the nature and the extent of lateral interaction between the ...
Influence of polyelectrolyte architecture on the electrokinetics and dewaterability of industrial membrane bioreactor activated sludge
(
Academic Press
, 2019 , Article)
Improvement of sludge dewaterability is greatly hindered by the presence of large amounts of interstitial water molecules trapped in the sludge as a result of strong hydrophilic characteristics. This study has investigated ...
Corrosion study of carbon steel in CO 2 loaded solution of N-methyldiethanolamine and L-arginine mixtures
(
Elsevier B.V.
, 2019 , Article)
This study presents an electrochemical corrosion investigation of carbon steel in blends of methyldiethanolamine (MDEA) and arginine (ARG) at different molar concentrations and solvent proportions. The effects of three ...
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 ...
Self-assembly of a surfactin nanolayer at solid-liquid and air-liquid interfaces
(
Springer Verlag
, 2016 , Article)
Surfactin, a sustainable and environmentally friendly surface active agent, is used as a model to study the adsorption of biosurfactants at hydrophobic and hydrophilic solid–liquid interfaces as well as the air–liquid ...
Influence of modified clay on the structure and performance of polysulfocomposite membrane
(
Desalination Publications
, 2018 , Article)
Highly porous modified clay material with large surface area known as ?Filtralite? was used as a filler for the preparation of polysulfone (PSf) composite membranes. Filtralite concentration in the membrane composition was ...
Carbamate Formation and Amine Protonation Constants in 2-Amino-1-Butanol–CO2–H2O System and Their Temperature Dependences
(
Springer New York LLC
, 2018 , Article)
The apparent protonation constant of an amino butanol (AB) and its carbamate formation constant in the CO2–H2O–AB system were determined at T = 298.15–328.15 K, and at various ionic strengths up to 0.2 mol·L−1 by potentiometric ...
Aqueous dispersions of carbon black and its hybrid with carbon nanofibers
(
Royal Society of Chemistry
, 2018 , Article)
The aqueous dispersions of a special type of carbon black (CB) in 1 M lithium bis(trifluoromethanesulfonimide) electrolyte is mainly controlled by the affinity of the aqueous electrolyte towards the CB particles rather ...
Fabrication of high flux nanofiltration membrane via hydrogen bonding based co-deposition of polydopamine with poly(vinyl alcohol)
(
Elsevier B.V.
, 2018 , Article)
The use of bio-inspired polydopamine (PDA) chemistry for membrane development has attracted increasing interest in recent years. This paper reports on the fabrication of new nanofiltration (NF) membrane with a robust and ...
Thermal degradation of aqueous amine/amino acid solutions in the presence and absence of CO 2
(
Institute of Physics Publishing
, 2018 , Conference)
The stability to thermal degradation of aqueous solutions of methyldiethanolamine (MDEA) and their mixtures with glycine (Gly), in the absence and the presence of CO 2 , was investigated by Gas chromatography-flame ionization ...
