Competitive adsorptive removal of promazine and promethazine from wastewater using olive tree pruning biochar: operational parameters, kinetics, and equilibrium investigations
( Springer Nature , 2023 , Article)This research aims to remove two phenothiazines, promazine (PRO) and promethazine (PMT), from their individual and binary mixtures using olive tree pruning biochar (BC-OTPR). The impact of individual and combinatory effects ... -
Computational Insights on the Electrocatalytic Behavior of [Cp*Rh] Molecular Catalysts Immobilized on Graphene for Heterogeneous Hydrogen Evolution Reaction
( Springer Nature , 2020 , Article)The heterogeneous metal-based molecular electrocatalyst can typically exhibit attractive features compared to its homogeneous analogue including recoverability and durability. As such, it is necessary to evaluate the ... -
Constituents of plants growing in Qatar - Part XIX. Flavonoids of Glossonema edule N. E. Br.
( Springer Nature , 1990 , Article)The study of the flavonoids of the unripe fruits of Glossonema edule, resulted in the isolation and identification of apigenin 6,8-di-C-glucoside (violanthin) and luteolin 7-O-glucoside. © 1990 Kluwer Academic Publishers. -
Continuous potentiometric monitoring of viagra (sildenafil) in pharmaceutical preparations using novel membrane sensors
( Springer Nature , 2006 , Article)Two potentiometric sensors responsive to sildenafil citrate (SC) drug (the active component of viagra) are described, characterized, compared and used for drug assessment. The sensors are based on the use of the ion-association ... -
Erratum to: Carbon black dispersions in surfactant-based microemulsion — Corrigendum (Journal of Materials Research, (2018), 33, 9, (1301-1307), 10.1557/jmr.2017.451)
( Springer Nature , 2018 , Other)In Youssry et al.1, the incorrect image was provided for Fig. 5. The correct figure is below. -
Human-Induced Pluripotent Stem Cell-Derived Cardiomyocytes (hiPSC-CMs) as a Platform for Modeling Arrhythmias
( Springer Nature , 2022 , Book chapter)Cardiac arrhythmias can arise due to a host of both genetic and acquired factors. Specifically, the genetic basis of arrhythmogenesis is not fully understood due to the lack of robust models that reliably recapitulate human ... -
Inner sphere oxidation of N,N′-ethylenebis(isonitrosoacetyleacetoneimine)copper(II) by N-bromosuccinimide in aqueous weakly acidic solutions
( Springer Nature , 2013 , Article)The kinetics of oxidation of N,N'-ethylenebis(isonitrosoacetyleacetoneimine) copper(II) complex, CuL, by N-bromosuccinimide (SBr) in weakly aqueous acidic solutions was studied under pseudo-first-order conditions. Plots ... -
Physical functionalization of multi-walled carbon nanotubes for enhanced dispersibility in aqueous medium
( Springer Nature , 2020 , Article)Noncovalent functionalization of multi-walled carbon nanotubes (MWCNTs) by anionic surfactants (sodium dodecylbenzene sulfonate; SDBS and sodium cholate; SC) results in stable aqueous dispersions. SDBS showed better ... -
Pinctada radiata (pearl oyster): A bioindicator for metal pollution monitoring in the Qatari waters (Arabian Gulf)
( Springer Nature , 1998 , Article)Bivalves are extensively used in monitoring programmes in the marine environment due to their ability to concentrate pollutants to several orders of magnitude above ambient levels in sea water. Commonly, the levels of ... -
Synthesis and electrochemical characterization of Cr-doped lithium-rich Li1.2Ni0.16Mn0.56Co0.08-xCrxO2 cathodes
( Springer Nature , 2018 , Article)Lithium-rich layer oxide, Li1.2Ni0.16Mn0.56Co0.08O2 (NMC), is a potential cathode candidate for high-energy density batteries. Issues such as cycling stability, rate performance, and cost are yet to be overcome before ... -
Turning waste avocado stones and montmorillonite into magnetite-supported nanocomposites for the depollution of methylene blue: adsorbent reusability and performance optimization
( Springer Nature , 2023 , Article)The existence of methylene blue (MB) in wastewater even as traces is raising environmental concerns. In this regard, the performances of four adsorbents, avocado stone biochar (AVS-BC), montmorillonite (MMT), and their ... -
Watermelon rinds as cost-efficient adsorbent for acridine orange: a response surface methodological approach
( Springer Nature , 2023 , Article)In the current investigation, watermelon rinds (WMR) have been utilized as an eco-friendly and cost-efficient adsorbent for acridine orange (AO) from contaminated water samples. Adsorption of AO onto raw (RWM) and thermally ...
