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 ...
Investigating the effect of temperature on calcium sulfate scaling of reverse osmosis membranes using FTIR, SEM-EDX and multivariate analysis
(
Elsevier B.V.
, 2020 , Article)
Membrane fouling is one of the major hurdles in widespread use of seawater reverse osmosis (SWRO) in desalination industry. There are various factors that affect the inorganic fouling or scaling of Reverse osmosis (RO) ...
Total Hg levels distribution in fish and fish products and their relationships with fish types, weights, and protein and lipid contents: A multivariate analysis
(
Elsevier
, 2023 , Article)
This study investigates the mercury (Hg) levels distribution in fish and fish products and their relationships with fish types, weights, protein, and lipid contents in Qatar. Principal component analysis (PCA) was employed ...
Improving properties of thin film nanocomposite membrane through polyethyleneimine intermediate layer: A parametric study
(
Elsevier B.V.
, 2021 , Article)
In this work, the polyethyleneimine (PEI)-interlayered thin film nanocomposite (iTFN) membranes were developed by establishing graphene oxide (GO)-incorporated polyamide (PA) layer atop PEI-coated polysulfone (PSf) substrate ...
Uptake of Reactive Black 5 by pumice and walnut activated carbon: Chemistry and adsorption mechanisms
(
Korean Society of Industrial Engineering Chemistry
, 2014 , Article)
The potential of using pumice and walnut wood activated carbon as low-cost adsorbents for the removal of the diazo dye Reactive Black 5 (RB5) from aqueous solutions was investigated. The Langmuir isotherm fit to the data ...
Investigating chlorophyll and nitrogen levels of mangroves at Al-Khor, Qatar: an integrated chemical analysis and remote sensing approach. Environmental Monitoring and Assessment
(
Springer Verlag
, 2016 , Article)
Mangroves are unique ecosystems that dominate tropical and subtropical coastlines around the world. They provide shelter and nursery to wide variety of species such as fish and birds. Around 73 species of mangroves were ...
Manganese-Loaded Activated Carbon for the Removal of Organosulfur Compounds from High-Sulfur Diesel Fuels
(
WILEY-VCH Verlag
, 2014 , Article)
The adsorptive capacity of activated carbon (AC) is significantly enhanced toward weakly interacting organosulfur compounds (OSC) from sulfur-rich diesel fuel. Sulfur compounds are selectively removed from diesel after ...
Caught basking in the winter sun: Preliminary data on winter thermoregulation in the Ethiopian hedgehog, Paraechinus aethiopicus, in Qatar
(
Academic Press
, 2016 , Article)
Biologists focus on thermoregulation of desert mammals in terms of how they minimize heat gain, and put less effort on how they maximize heat gain during the cooler months. Heat gain may contribute to significant energy ...
Novel bioadsorbents based on date pits for organophosphorus pesticide remediation from water
(
Elsevier Ltd
, 2020 , Article)
The aim of the study was to examine the efficiency of date pits as an adsorbent to remove the organophosphate pesticide (profenofos) from water. A thermodynamic study was carried out to determine the homogeneity and ...
Mechanistic understanding of the adsorption and thermodynamic aspects of cationic methylene blue dye onto cellulosic olive stones biomass from wastewater
(
Nature Research
, 2020 , Article)
In the current study, the mechanistic understanding of the adsorption isotherm and thermodynamic aspects of cationic methylene blue (MB) dye adsorption onto cellulosic olive stones biomass from wastewater were investigated. ...
