( John Wiley and Sons Ltd , 2021 , Article)In this study, styrene-butadiene-styrene (SBS) was used to develop a novel functionalized electrospun membrane for the effective treatment of heavy metals in direct contact membrane distillation (DCMD) applications. ... -
Emergent community architecture despite distinct diversity in the global whale shark (Rhincodon typus) epidermal microbiome
( Nature Research , 2023 , Article)Microbiomes confer beneficial physiological traits to their host, but microbial diversity is inherently variable, challenging the relationship between microbes and their contribution to host health. Here, we compare the ... -
Endophytes and Halophytes to Remediate Industrial Wastewater and Saline Soils: Perspectives from Qatar
( MDPI , 2022 , Article Review)Many halophytes are considered to be salt hyperaccumulators, adopting ion extrusion and inclusion mechanisms. Such plants, with high aboveground biomass, may play crucial roles in saline habitats, including soil desalination ... -
ENDOTHELIAL NITRIC OXIDE ACTIVITY & BIOAVAILABILITY DURING OBESITY CONDITIONS
(2017 , Poster)Obesity has been recognized as a pandemic and linked with several metabolic dysfunctions. One of the hallmarks in the onset of obesity is the development of hypertension coupled with endothelial dysfunction. (ED) A fundamental ... -
Energy depletion and opportunistic microbial colonisation in white syndrome lesions from corals across the Indo-Pacific
( Nature Research , 2020 , Article)Corals are dependent upon lipids as energy reserves to mount a metabolic response to biotic and abiotic challenges. This study profiled lipids, fatty acids, and microbial communities of healthy and white syndrome (WS) ... -
Energy efficiency of direct contact membrane distillation
( Elsevier B.V. , 2018 , Article)Membrane distillation (MD) is a promising technology due to its ability to function using low temperature differences and low-quality heat sources, thus allowing it to operate on solar or waste heat. The flux and energy ... -
