Investigation on the effect of LiTFSI salt on PVDF-based Solid Polymer Electrolyte Membranes for Lithium-Ion Batteries
(
Qatar University Press
, 2021 , Poster)
Solid polymer electrolytes provide an alternative approach to providing improved safety whilst concurrently acting as a performance enhanced separator within Lithium-ion batteries (LIBs). This investigation studies the ...
Detecting Organic Nitrogen with 1H-15N HMBC Spectra
(
Qatar University Press
, 2021 , Poster)
NMR spectroscopy has been the most important tool for organic chemistry research, providing detailed structure information. While 1H and 13C NMR spectra were frequently measured, 15N NMR spectra were relatively rare, even ...
Spectrophotometric Determination of the Honey Bee Quality
(
Qatar University Press
, 2021 , Poster)
Honey produced by bees from nectar in flowers and plants, is an aqueous supersaturated sugar solution, mainly monosaccharide (fructose and glucose) (70%–80%) and water (10%–20%). 5-Hydroxymethylfurfural (5-HMF) content in ...
Synthesis of Novel Aqua ƞ4-NNNO/Cu(II) Complexes as Rapid and Selective Oxidative Catalysts for O-Catechol: Fluorescence, Spectral, Chromotropism and Thermal Analyses
(
MDPI
, 2021 , Article)
A new tetradentate Schiff base (SB), (E)-4-fluoro-2-(1-((2-(piperazin-1-yl)ethyl)imino)ethyl)phe-nol, was synthesized from condensation of 2-(1-piperazinyl)ethylamine and 5-fluoro-2-hydroxyacetophe-none. This ligand was ...
Systematic laboratory approach to produce Mg-rich carbonates at low temperature
(
Royal Society of Chemistry
, 2021 , Article)
Dolomite is a common Mg-rich carbonate in the geological record, but the mechanism of its formation remains unclear. At low temperature, the incorporation of magnesium ions into the carbonate minerals necessary to form ...
The effect of graphene structural integrity on the power factor of tin selenide nanocomposite
(
Elsevier
, 2021 , Article)
Tin selenide graphene nanocomposites (SnSe/GNPs) were fabricated with high-energy ball milling and hot pressing by varying the milling time of graphene. The effect of ball milling time on the graphene integrity and the ...
Insights into the generation of hydroxyl radicals from H2O2 decomposition by the combination of Fe2+ and chloranilic acid
(
Springer
, 2021 , Article)
In this work, the degradation of chloranilic acid (CAA) by chemical oxidation with H2O2 alone and in the presence of ferrous iron Fe2+ catalyst was investigated in order to improve our understanding on the novel metal-independent ...
The Carcinogenic and Non-Carcinogenic Health Risks of Metal(oid)s Bioaccumulation in Leafy Vegetables: A Consumption Advisory
(
Frontiers Media
, 2021 , Article)
High levels of metal(oid)s in soil or food pose a severe health risk to humans. The potential toxicants find their way into the living systems via the food chain, following bioaccumulation in edible plants, including leafy ...
Ecological and health risks assessment of potentially toxic metals and metalloids contaminants: A case study of agricultural soils in Qatar
(
MDPI

© 2021 by the authors. Licensee MDPI, Basel, Switzerland. In recent years, Qatar has witnessed exponential growth in the human population, urbanization, and increased anthropogenic activities, including agriculture. ...
Energy recovery and nutrients recycling from municipal sewage sludge
(
Elsevier
, 2020 , Article)
Hydrothermal Liquefaction (HTL) could be a promising and better alternative to other techniques for energy recovery from municipal sewage sludge (MSS). However, the nutrients (i.e., N, and P) recovery potential from the ...
