3D characterization of sand particle-to-particle contact and morphology
Druckrey, Andrew M.; Alshibli, Khalid A.; Al-Raoush, Riyadh I. ( Elsevier Ltd , 2016 , Article)Particle morphology, orientation, and contact configuration play a significant role in the engineering properties of granular materials. Accurate three-dimensional (3D) characterization of these parameters for experiments ... -
A microbial fuel cell configured for the remediation of recalcitrant pollutants in soil environment
Mohanakrishna, Gunda; Al-Raoush, Riyadh I.; Abu-Reesh, Ibrahim M.; Pant, Deepak ( Royal Society of Chemistry , 2019 , Article)A pristine soil environment supports a healthy soil biodiversity, which is often polluted with recalcitrant compounds. The bioelectrochemical remediation of the contaminated soils using bioelectrochemical systems (BESs) ... -
Biodegradation Kinetics of Benzene and Naphthalene in the Vadose and Saturated Zones of a (Semi)-Arid Saline Coastal Soil Environment
Ngueleu, Stephane K.; Al-Raoush, Riyadh I.; Shafieiyoun, Saeid; Rezanezhad, Fereidoun; Cappellen, Philippe Van ( Hindawi Limited , 2019 , Article)Biodegradation is a key process for the remediation of sites contaminated by petroleum hydrocarbons (PHCs), but this process is not well known for the (semi)-Arid coastal environments where saline conditions and continuous ... -

Kondaveeti, Sanath; Patel, Sanjay K. S.; Woo, Janghun; Wee, Ji Hyang; Kim, Sang-Yong; Al-Raoush, Riyadh I.; Kim, In-Won; Kalia, Vipin Chandra; Lee, Jung-Kul... more authors ... less authors ( Springer , 2019 , Article)A novel cellobiohydrolase (CBH)-generating fungi have been isolated and categorized as Schizophyllum commune KMJ820 based on morphology and rDNA gene sequence. Cellulose powder was used as carbon source, the total enzyme ... -
Experimental investigation of the influence of grain geometry on residual NAPL using synchrotron microtomography
Al-Raoush, Riyadh I. ( Elsevier B.V. , 2014 , Article)The objective of this work was to investigate the impact of grain geometry (size and shape) of porous media on the morphology of residual NAPL. Synchrotron microtomography was used to obtain maps of residual NAPL in ... -
Gas driven fracture during gas production using 3D synchrotron computed tomography
Jarrar, Zaher A.; Alshibli, Khalid A.; Al-Raoush, Riyadh I.; Jung, Jongwon ( Springer Verlag , 2019 , Conference Paper)During methane gas production from hydrate bearing sandy sediments, fine particles can migrate or clog the pores of sediments. Fines clogging induces a change in pressure gradient which affects the gas flow pattern and ... -
Gas Driven Fracture during Gas Production using HeleShaw Cell
Al-Raoush, Riyadh; Jarrar, Zaher; Alshibli, Khalid; Jung, Jongwon ( Hamad bin Khalifa University Press (HBKU Press) , 2018 , Conference Paper)Methane hydrate is considered a potential energy source, with worldwide reserves on the order of 500-10,000 Gt of carbon. The production of Methane from hydratebearing sediments requires hydrate dissociation for releasing ... -
Impact of fines type on gas flow using 3D micro-computed tomography
Al-Raoush, Riyadh; Hannun, Jamal; Jarrar, Zaher; Alshibli, Khalid; Jung, Jongwon ( Society of Petroleum Engineers , 2019 , Conference Paper)Methane hydrates are promising unconventional energy source with natural reserves above 1,000 Trillion m3. Hydrates are found in saturated sandy sediments, where multi-phase flow of gas takes place through sediment's pores, ... -
Impact of Pore Morphology on Colloid Migration at Variable Saturation Levels of Natural Porous Media
Albaba, Mhd. Taisir; Hannun, Jamal; Al-Raoush, Riyadh ( Qatar University Press , 2023 , Conference Paper)The migration of colloids within porous media has a critical impact on many important industrial processes such as oil production and groundwater recharge. Colloids can clog the pore space and hence impair the permeability ... -
