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 ...
Smart Synthesis of Trimethyl Ethoxysilane (TMS) Functionalized Core–Shell Magnetic Nanosorbents Fe3O4@SiO2: Process Optimization and Application for Extraction of Pesticides
(
MDPI AG
, 2020 , Article)
In the current study, a smart approach for synthesizing trimethyl ethoxysilane–decorated magnetic-core silica-nanoparticles (TMS-mcSNPs) and its effectiveness as nanosorbents have been exploited. While the magnetite core ...
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 ...
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 ...
Microbially induced calcite precipitation in calcareous soils by endogenous Bacillus cereus, at high pH and harsh weather
(
Elsevier
, 2020 , Article)
Microbially induced calcite precipitation (MICP) improves the physical properties of soils by increasing the solid content, decreasing the pore sizes and improving the rigidity of the particle-to-particle contact ending ...
Investigating the effect of polymer-modified graphene oxide coating on RO membrane fouling
(
Elsevier
, 2022 , Article)
The development of novel reverse osmosis (RO) membranes resistant to multiple types of fouling is a need to secure clean water production and meet rising water demands. In this paper, the RO membrane surface-functionalized ...
Algal-algal bioflocculation enhances the recovery efficiency of Picochlorum sp. QUCCCM130 with low auto-settling capacity
(
Elsevier B.V.
, 2023 , Article)
Large-scale production of microalgal biomass is still considered non-viable due to the high cost and energy required for harvesting. A fast, cost-effective, and successful harvesting technique has become widely sought after ...
Microalgal Feedstock for Biofuel Production: Recent Advances, Challenges, and Future Perspective
(
MDPI
, 2023 , Article)
Globally, nations are trying to address environmental issues such as global warming and climate change, along with the burden of declining fossil fuel reserves. Furthermore, countries aim to reach zero carbon emissions ...
Utilization of nitrogen-rich agricultural waste streams by microalgae for the production of protein and value-added compounds
(
Elsevier B.V.
, 2023 , Article)
Current food and feed production practices via agricultural processes generate waste streams often rich in nitrogen. Conversion of the nitrogen in agricultural waste into valuable products would prevent environmental ...
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 ...
