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.
, 2021 , Article)
This study investigated the feasibility of microalgal biomass production using waste nitrogen fertilizers (WNFs) generated by the Qatar Fertiliser Company (QAFCO). From the plant, three types of WNFs (WNF1, WNF2, and WNF3) ...
Model predictive control for optimal energy management of connected cluster of microgrids with net zero energy multi-greenhouses
(
Elsevier
, 2021 , Article)
This paper intends to present a cooperative control framework for a connected cluster of microgrids with multi-smart greenhouses creating a smart local electric grid in the framework of smart grids. Each microgrid comprises ...
Production and investigation of flexible nanofibers of sPEEK/PVP loaded with RuO2 nanoparticles
(
Elsevier
, 2021 , Article)
Electrospinning technique was employed to fabricate composite nanofibers/nanoparticles of sulfonated polyether ether ketone, polyvinylpyrrolidone, and ruthenium oxide (sPEEK/PVP/RuO2). The samples were synthesized with ...
Variation of soil properties with sampling depth in two different light-textured soils after repeated applications of urban sewage sludge
(
Elsevier
, 2021 , Article)
Semi-arid agricultural soils have increasingly been subjected to urban sewage sludge (USS) applications due to accelerated soil depletion and shortages in manure supply. Research studies addressing USS reuse have mostly ...
Static and dynamic investigations on leaching/retention of nutrients from raw poultry manure biochars and amended agricultural soil
(
MDPI
, 2021 , Article)
In this study, nutrients release/adsorption from/by raw poultry manure-derived biochar produced at a pyrolysis temperature of 600 °C (RPM-B) was assessed under static and dynamic conditions. Batch sequential leaching ...
Use of lignite as a low-cost material for cadmium and copper removal from aqueous solutions: Assessment of adsorption characteristics and exploration of involved mechanisms
(
MDPI
, 2021 , Article)
Lignite, as an available and low-cost material, was tested for cadmium (Cd) and copper (Cu) removal from aqueous solutions under various static experimental conditions. Experimental results showed that the removal efficiency ...
