Bio-Based Self-Healing Concrete for Sustainable and Durable Concrete Infrastructure
( Qatar University Press , 2023 , Conference Paper)In this study, bio-self-healing concrete was manufactured using a natural phenomenon called microbial-induced calcium carbonate precipitation (MICP). The bacillus cereus bacteria isolated from Qatari soil was used for this ... -
Characterization and assessment of process water from oil and gas production: A case study of process wastewater in Qatar
( Elsevier , 2022 , Article)This study characterized and assessed three different process water (PWWs) (S-1, S-2, and S-3) from oil and gas production in Qatar. The wastewater generated in various processing stages contains many harmful components ... -
Characterization of Commercial Reverse Osmosis and Nanofiltration Membranes for Membrane Fouling
( Hamad bin Khalifa University Press (HBKU Press) , 2018 , Conference Paper)Membrane Filtration technique is being accepted worldwide as an environment friendly and energy efficient technique in Desalination Industry as compared to Thermal Desalination techniques. However, the performance of ... -
Chemical Characterization and Source Identification of Beached Oil from Two Areas Along the North-Western Coast of Qatar
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)Over the years there have been several reports of oil spills affecting particularly the northern coast of Qatar. In most cases, the source of oil spills is not identified. The spilled oils are very resistant to degradation ... -
Date pits based nanomaterials for thermal insulation applications - Towards energy efficient buildings in Qatar
( Public Library of Science , 2021 , Article)Air-conditioning systems make the most significant part of energy consumption in the residential sector. There is no denying that it is essential to produce a comfortable indoor thermal environment for residents in a ... -
Development and application of bio-waste-derived adsorbents for the removal of boron from groundwater
( Elsevier , 2022 , Article)This study investigates the development and application of bio-waste-derived adsorbents for the removal of boron from groundwater. The boron removal from groundwater was explored by bio-waste-derived adsorbents such as ... -
Evidencing the diversity and needs of adjustment of the nutritional requirements for hydrocarbon-degrading activity of: Pseudomonas aeruginosa adapted to harsh conditions using 2<sup>n</sup> full factorial design
( Royal Society of Chemistry , 2017 , Article)To overcome the partial or complete failure of oil hydrocarbon bioremediation due to weathering processes, occurring in most oil producing and spilling areas, nutritional requirements of the most widely used bacterium, ... -
Evidencing the role of carbonic anhydrase in the formation of carbonate minerals by bacterial strains isolated from extreme environments in Qatar
( Elsevier , 2022 , Article)Calcium carbonate, one of the most abundant minerals in the geological records is considered as primary source of the carbon reservoir. The role of microorganisms in the biotic precipitation of calcium carbonate has been ... -
Immobilization of heavy metals by microbially induced carbonate precipitation using hydrocarbon-degrading ureolytic bacteria
( Elsevier , 2022 , Article)Crude oil contamination introduces multiple threats to human health and the environment, most of which are from toxic heavy metals. Heavy metals cause significant threats because of their persistence, toxicity, and ... -
Interaction between indigenous hydrocarbon-degrading bacteria in reconstituted mixtures for remediation of weathered oil in soil
( Elsevier , 2022 , Article)It has been demonstrated that biostimulation is necessary to investigate the interactions between indigenous bacteria and establish an approach for the bioremediation of soils contaminated with weathered oil. This was ... -
