(
Academic Press Inc.
, 2021 , Article)
This study underlines the biotechnical valorization of the accumulated and unusable remains of agro-industrial orange fruit peel waste to produce α-amylase under submerged conditions by Streptomyces sp. KP314280 (20r). The ...
Functionalization of silica-coated magnetic nanoparticles as powerful demulsifier to recover oil from oil-in-water emulsion
(
Elsevier Ltd
, 2021 , Article)
This study presents an innovative approach for the preparation of Fe3O4 nanoparticles covered with SiO2 shell (denoted as Fe–Si-MNP), which were used to recover oil recovery from oil-in-water emulsion (O/W-emul). The ...
Enhanced oil recovery using hyperbranched polyglycerol polymer-coated silica nanoparticles
(
Elsevier Ltd
, 2021 , Article)
Functionalized Fe3O4?SiO2 magnetic nanoparticles (Fe?Si-MNPs) coated with hyperbranched polyglycerol polymer were prepared and tested for oil recovery from oil in water (O/W) emulsions. The structure, chemistry, and surface ...
Solar photo-catalytic production of hydrogen by irradiation of cobalt co-doped TiO2
(
Elsevier Ltd
, 2021 , Article)
Cobalt (Co) co-doped TiO2 photocatalysts (P–Cs) with differing mass fractions of Co (% wt.) were synthesized, characterized, and evaluated toward the solar photocatalytic production of hydrogen (SP–CPOH) from a pure electron ...
Application of Fe3O4 magnetite nanoparticles grafted in silica (SiO2) for oil recovery from oil in water emulsions
(
Elsevier Ltd
, 2021 , Article)
In this study, an innovative magnetic demulsifier (MD) was prepared by grafting a silica layer onto the surface of the Fe3O4 magnetic nanoparticles (MNPs) using the modified Stober process. The MD was characterized using ...
Fabrication of titanium dioxide nanomaterial for implantable highly flexible composite bioelectrode for biosensing applications
(

Implantable and stretchable electrodes have managed to progress the medical field from a medical diagnosis aspect to a patient treatment level. They offer the ability to detect biosignals and conduct electrical current to ...
Bio-sorption of toxic metals from industrial wastewater by algae strains Spirulina platensis and Chlorella vulgaris: Application of isotherm, kinetic models and process optimization
(
Elsevier B.V.
, 2021 , Article)
The present study evaluates the effect of an acidic treatment on the improvement of the percentage removal of toxic metal (%TMrem) from wastewater by algae strains (Spirulina platensis (SP) and Chlorella vulgar (CV)) under ...
Innovative bppo anion exchange membranes formulation using diffusion dialysis-enhanced acid regeneration system
(
MDPI AG
, 2021 , Article)
Recycling of acid from aqueous waste streams is crucial not only from the environmental point of view but also for maturing the feasible method (diffusion dialysis). Anion exchange membrane (AEM)–based diffusion dialysis ...
