Hydrogen Underground Storage in Silica-Clay Shales: Experimental and Density Functional Theory Investigation
( American Chemical Society , 2023 , Article)In the context of reducing the global emissions of greenhouse gases, hydrogen (H2) has become an attractive alternative to substitute the current fossil fuels. However, its properties, seasonal fluctuations, and the lack ... -
Hydropriming with moringa leaf extract mitigates salt stress in wheat seedlings
( MDPI , 2021 , Article)Salinity is the major constraint that decreases the yield and production of crops. Wheat has a significant value in agricultural food commodities. The germination and growth of wheat seedlings are a big challenge in ... -
Hydrothermal liquefaction of marine microalgae biomass using co-solvents
( Elsevier B.V. , 2019 , Article)Hydrothermal liquefaction (HTL) of microalgae biomass is a promising conversion technology in which wet biomass is treated under high temperature (280–350 °C) and pressure (5–21 MPa), and the associated water in the wet ... -
Hydrothermally grown ZnO electrodes for improved organic photovoltaic devices
( Elsevier B.V. , 2018 , Article)Here we report a simple, solution based processing route for the formation of large surface area electrodes resulting in improved organic photovoltaic devices when compared with conventional planar electrodes. The ... -
Hyperhydration-induced decrease in urinary luteinizing hormone concentrations of Male athletes in doping control analysis
( Human Kinetics Publishers Inc. , 2019 , Article)Low urinary luteinizing hormone (LH) values have been discussed as a marker to detect steroid abuse. However, suppressed LH concentrations related to highly diluted urine samples could be a misleading indication of anabolic ... -
Hypertrophic cardiomyopathy-linked variants of cardiac myosin-binding protein C3 display altered molecular properties and actin interaction
( Portland Press Ltd , 2018 , Article)The most common inherited cardiac disorder, hypertrophic cardiomyopathy (HCM), is characterized by thickening of heart muscle, for which genetic mutations in cardiac myosin-binding protein C3 (c-MYBPC3) gene, is the leading ... -
Hypoxia in the central Arabian Gulf Exclusive Economic Zone (EEZ) of Qatar during summer season
( Elsevier , 2015 , Article)Abstract One of the most fascinating and unexpected discoveries during the Qatar University Marine Expeditions to the marine Exclusive Economic Zone (EEZ) of Qatar in 2000–2001, was the detection of a hypoxic water layer ... -
IBX/KI promoted synthesis of 2, 5-disubstituted 1, 3, 4-oxadiazoles
( Bentham Science Publishers B.V. , 2018 , Article)Background: Oxadiazoles are privileged scaffolds in different areas of medicinal, pesticidal, polymer and material science. They act as anticancer, benzodiazepine receptor agonists, antimicrobial, analgesic, diuretic and ... -
ICT sector, digitization and environmental sustainability: A systematic review of the literature from 2000 to 2022
( Elsevier , 2023 , Article Review)In line with an intensified call for reducing greenhouse emissions and curbing the effects of climate change, scientists and experts have looked to information communication technology (ICT) and digitization as critical ... -
Identification and mapping of brain natriuretic peptide in the normal ventricular myocardium of a desert-dwelling mammalian model, the camel (Camelus dromedarius): Immunohistochemical and ultrastructural study
( Wiley-Liss Inc. , 2019 , Article)Brain natriuretic peptide (BNP) is mainly produced in the ventricular myocardium, where it is released into the circulation, producing rapid volume decrease by diuresis, natriuresis, and water shift into the extracellular ... -
Identification of Important Sea Turtle Areas (ITAs) for hawksbill turtles in the Arabian Region
( Elsevier , 2014 , Article)We present the first data on hawksbill turtle post-nesting migrations and behaviour in the Arabian region. Tracks from 90 post-nesting turtles (65 in the Gulf and 25 from Oman) revealed that hawksbills in the Arabian region ... -
