Interaction between indigenous hydrocarbon-degrading bacteria in reconstituted mixtures for remediation of weathered oil in soil
( Elsevier , 2022 , Article)It has been demonstrated that biostimulation is necessary to investigate the interactions between indigenous bacteria and establish an approach for the bioremediation of soils contaminated with weathered oil. This was ... -
Valorization of palm tree (Phoenix dactylifera L.) leaves from harsh weather climate by silage using endogenous lactic acid bacteria, and application of MALDI-TOF MS for study of populations dynamics
( Elsevier , 2023 , Article)Preservation of green palm leaves by silage preserves them as green feed in addition to the added value of probiotics and prebiotics. In this work, the characterization of fresh palm tree leaves was performed. The isolation ... -
Shear and Tensile Strength Measurements of CaCO 3 Cemented Bonds between Glass Beads Treated by Microbially Induced Carbonate Precipitation
( American Society of Civil Engineers (ASCE) , 2023 , Article)The particle-scale shear and tensile strength measurements of microbial-induced calcite precipitation (MICP) treatment have been investigated in this paper. Glass beads were used to represent sand particles. Three ... -
A comparative physicochemical property assessment and techno-economic analysis of biolubricants produced using chemical modification and additive-based routes
( Elsevier , 2022 , Article)Several edible and non-edible oil sources are currently being developed as renewable basestocks for biolubricant production. However, these feedstocks possess undesirable physicochemical properties limiting their lubricant ... -
Microalgal bioremediation of brackish aquaculture wastewater
( Elsevier , 2023 , Article)Rapid aquaculture industry development contributed to a major increase in aquaculture wastewater generation. In the context of a circular economy, aquaculture wastewater treatment should simultaneously recover nutrients ... -
Biocrude oil production from a self-settling marine cyanobacterium, Chroococcidiopsis sp., using a biorefinery approach
( Elsevier , 2023 , Article)Although the whole microalgal biomass is typically used as a feedstock for hydrothermal liquefaction (HTL), the conversion of a primary metabolite (i.e., carbohydrate) to biocrude is very low. In this study, a self-settling ... -
Uptake of Reactive Black 5 by pumice and walnut activated carbon: Chemistry and adsorption mechanisms
( Elsevier , 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 ... -
A solid-phase extractant based on microemulsion modified date pits for toxic pollutants
( Elsevier , 2013 , Article)Application of microemulsion modified raw date pits as an inexpensive solid extractant for removing methylene blue (MB), copper ion (Cu2+) and cadmium ion (Cd2+) has been presented. The results summarised herein are also ... -
Upside-Down Preference in the Forskolin-Induced In Vitro Differentiation of 50B11 Sensory Neurons: A Morphological Investigation by Label-Free Non-Linear Microscopy.
( MDPI , 2023 , Article)In this study, we revealed a peculiar morphological feature of 50B11 nociceptive sensory neurons in in vitro culture related to the forskolin-induced differentiation of these cells growing upside-down on cover glass supports. ... -
Synthesis of nanostructured novel ion-imprinted polymer for selective removal of Cu2+ and Sr2+ ions from reverse osmosis concentrated brine
( Elsevier , 2023 , Article)This study aims to prepare an ion-imprinted polymer (IIP) using copper sulfate as a template and potassium persulfate as an initiator to selectively adsorb copper ions (Cu2+) from aqueous solutions and in an attempt to ... -
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 ... -
Recent developments in ultrafiltration membrane technology for the removal of potentially toxic elements, and enhanced antifouling performance: A review
( Elsevier , 2023 , Article)The presence of high concentrations of heavy metals (potentially toxic elements) in water bodies generates serious environmental issues and health problems that led to a dramatic increase in wastewater treatment costs. ... -
Distribution and diversity of aquatic insects in different water bodies of Qatar
( Instituto Internacional de Ecologia , 2024 , Article)Aquatic insect fauna remains an important tool for bio indication of environmental disturbance, while maintaining a healthy aquatic system. The purpose of the study was to document and to identify the diversity and ... -
Photodegradation and Its Effect on Plant Litter Decomposition in Terrestrial Ecosystems: A Systematic Review
( MDPI , 2023 , Article Review)Photodegradation is an important mechanism that affects carbon and nutrient cycling; a significant amount of data has been reported previously. The present review includes the effect of a wider spectrum of solar radiation ... -
An overview of heavy metals toxicity in plants, tolerance mechanism, and alleviation through lysine-chelation with micro-nutrients—A novel approach
( Springer , 2022 , Article Review)Abstract: Plants must adapt themselves to the prevailing conditions for their survival, resulting in the acquisition of a wide range of metal tolerance mechanisms. Although many metal elements are essential for the growth ... -
Pilot-scale crossflow ultrafiltration of four different cell-sized marine microalgae to assess the ultrafiltration performance and energy requirements
( Elsevier , 2023 , Article)Four marine microalgae (e.g., Tetraselmis, Picochlorum, Dunaliella, and Synechococcus) with different cell sizes were harvested using pilot-scale ultrafiltration. Average permeate fluxes were 16.75, 19, 25.35, and 33.75 ... -
