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 ...
Role of ultrasound in the management of diabetes in pregnancy
(
Taylor and Francis Ltd.
, 2015 , Article)
The purpose of this review is to discuss the established role of ultrasound (US) in the management of pregnancy complicated by diabetes mellitus (DM), as well as new developments with regard to the use of US in this ...
Synoptic analysis of direct contact membrane distillation performance in Qatar: A case study
(
Elsevier B.V.
, 2015 , Article)
The aim of this study is to evaluate a bench scale direct contact membrane distillation (DCMD) performance using flat sheet polytetrafluoroethylene (PTFE) membrane at different inlet flow rates, temperatures, and salinity ...
The application of iron coated activated alumina, ferric oxihydroxide and granular activated carbon in removing humic substances from water and wastewater: Column studies
(
Elsevier B.V.
, 2010 , Article)
The efficiency of iron coated activated alumina, ferric oxihydroxide and granular activated carbon for the removal of humic substance (HS) from water and wastewater was demonstrated in batch studies. This paper investigated ...
Removal of carbamazepine from water by a novel TiO2-coconut shell powder/UV process: Composite preparation and photocatalytic activity
(2013 , Article)
A novel TiO2-coconut shell powder (TCNSP) composite, prepared by the controlled sol-gel method with a subsequent heat treatment, was investigated as an innovative photocatalytic absorbent for the removal of carbamazepine ...
Phenol degradation by powdered metal ion modified titanium dioxide photocatalysts
(2012 , Article)
Conventional water purification and disinfection generally involve potentially hazardous substances, some of which known to be carcinogenic in nature. Titanium dioxide photocatalytic processes provide an effective route ...
A solid-phase extractant based on microemulsion modified date pits for toxic pollutants
(2013 , Article)
Application of microemulsion modified raw date pits as an inexpensive solid extractant for removing methylene blue (MB), copper ion (Cu2+) and cadmium ion (Cd2+) has been presented. The results summarised herein are also ...
Bioenergy II: Bio-ethanol from municipal solid waste (MSW): The role of biomass properties and structures during the ethanol conversion process
(
Berkeley Electronic Press
, 2010 , Article)
The emerging biofuel industry demands large amount of biomass feedstock. Although commercial ethanol has been produced from primary biomass sources such as corns, the global food crisis caused by the use of primary biomass ...
Kinetics of humics removal from water and wastewater using granular activated carbon, iron-coated activated alumina, and beta ferric oxihydroxide
(2010 , Article)
Application of kinetic models to represent the removal of humic substances from water and wastewater was investigated. An adsorbate-adsorbent system was represented by humic substances and three adsorbents, namely granular ...
Study on hydroxylammonium-based ionic liquids. II. Computational analysis of CO2 absorption
(
American Chemical Society
, 2011 , Article)
In the previous work of this series, we reported a wide experimental and computational analysis of the properties of hydroxylammonium-based ionic liquids. This family of ionic liquids shows very favorable economical, ...
