Eggshell membrane as a novel bio sorbent for remediation of boron from desalinated water
( Academic Press , 2018 , Article)This study investigated the use of eggshell membrane (ESM) as a bio-sorbent and the effect of temperature, pH, and initial concentration on its efficiency. Furthermore, by altering the chemical composition, modified eggshell ... -
Electronic waste considerations in the Middle East and North African (MENA) region: A review
( Elsevier , 2023 , Article Review)Waste Electrical and Electronic Equipment or e-waste is a waste stream that has multiplied profoundly in recent years. Currently, many researchers focused on the study of e-waste. The Middle East & North Africa (MENA) is ... -
Electropolymerized phenol derivatives as permselective polymers for biosensor applications
( The Royal Society of Chemistry , 2015 , Article)Amperometric biosensors are often coated with a polymeric permselective film to avoid electroactive interference by reducing agents present in the target medium. Phenylenediamine and phenol monomers are commonly used to ... -
Electrospun Al2O3 hydrophobic functionalized membranes for heavy metal recovery using direct contact membrane distillation
( 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 ... -
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 Review)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 ... -
