Fabrication of H2S sensitive gas sensors formed of SnO2–Fe2O3 composite nanoparticles
(
Elsevier B.V.
, 2021 , Article)
Nanocomposites of metal oxide are considered promising candidates for developing novel gas sensors of exceptional performance. Composite SnO2–Fe2O3 nanoparticles are produced in this work by a modified sole-gel method, and ...
Circular Economy in Basic Supply: Framing the Approach for the Water and Food Sectors of the Gulf Cooperation Council Countries
(
Elsevier
, 2021 , Article)
The circular economy concept can enhance sustainability through restructuring consumption and production patterns using innovative designs and business models. This core premise is highly relevant for the interlinked water ...
Cultivating microalgae in desert conditions: Evaluation of the effect of light‐temperature summer conditions on the growth and metabolism of nannochloropsis qu130
(
MDPI
, 2021 , Article)
Temperature and light are two of the most crucial factors for microalgae production. Variations in these factors alter their growth kinetics, macromolecular composition and physiological properties, including cell membrane ...
Biocrude oil and high-value metabolite production potential of the Nitzschia sp.
(
Springer Science and Business Media Deutschland GmbH
, 2021 , Article)
Diatom biomass could be an alternative feedstock for producing bio-oil through hydrothermal liquefaction (HTL) technique. Additionally, diatom biomass could have high-value metabolites, such as pigments and polyunsaturated ...
Potential of microalgae as a sustainable feed ingredient for aquaculture
(
Elsevier B.V.
, 2021 , Article)
An increase in fish consumption, combined with a decrease in wild fish harvest, is driving the aquaculture industry at rapid pace. Today, farmed seafood accounts for about half of all global seafood demand for human ...
Treatment of wastewaters by microalgae and the potential applications of the produced biomass-a review
(
MDPI AG
, 2021 , Article)
The treatment of different types of wastewater by physicochemical or biological (nonmicroalgal) methods could often be either inefficient or energy-intensive. Microalgae are ubiquitous microscopic organisms, which thrive ...
Nutrients and energy digestibility of microalgal biomass for fish feed applications
(
MDPI
, 2021 , Article)
Aquafeed accounts for at least 75-90% of aquaculture's operating costs. Traditional aquafeed ingredients such as fishmeal, fish oil, and soybean meal are unsustainable; further, their increasing cost necessities developing ...
Potential utilization of waste nitrogen fertilizer from a fertilizer industry using marine microalgae
(
Elsevier B.V.
