TDDFT Studies on sheet size-dependency of optoelectronic properties of 2d silicon
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
Silicene, a two-dimensional (2D) silicon nanosheet, has gained immense interest due to potential applications, better compatibility, and expected integration with current silicon (Si) technology. This work explores the ...
Effect of pH on dissolution of iron sulfide scales using THPS
(
Society of Petroleum Engineers (SPE)
, 2019 , Conference Paper)
Iron Sulfides scale has been a critical problem for oil and gas wells for several decades. One of the best candidates to remove these scales is tetrakis(hydroxymethyl)phosphonium sulfate (THPS). Most studies on the dissolution ...
Development of novel thin film composite reverse osmosis membranes for desalination
(
American Institute of Physics Inc.
, 2019 , Conference Paper)
Microporous Polyetherimide (PEI) membranes were prepared by wet phase inversion at different temperatures. The thin film composites (TFC) of polyamide on microporous PEI were prepared using meta-Phenylenediamine (MPD) and ...
Application of DFT in iron sulfide scale removal from oil and gas wells
(
European Association of Geoscientists and Engineers, EAGE
, 2019 , Conference Paper)
Scale formation including those formed by iron sulfides have been a major hassle in the upstream sector of the oil and gas industry for many decades. Iron Sulfide scales including pyrite (FeS2) and troilite (FeS) often ...
Improvement of PVA gel properties for cell immobilization
(
Avestia Publishing
, 2019 , Conference Paper)
This study investigates the characterization and the ability of polyvinyl alcohol (PVA) gel to be used in the area of wastewater treatment as biomass immobilization matrix. The PVA matrix was prepared through the ...
