Health risk assessment induced by trace toxic metals in tap drinking water: Condorcet principle development
(
Elsevier Ltd
, 2022 , Article)
Acute exposure to trace metals (TMs) in water is hazardous to human health. The average concentrations (Cavg.) and carcinogenic (CAR) and non-carcinogenic (non-CAR) risks of eight TMs to World Health Organization's (WHO) ...
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 ...
Paper mill sludge as a source of sugars for use in the production of bioethanol and isoprene
(
MDPI AG
, 2020 , Article)
Paper mill sludge (PMS) solids are predominantly comprised of cellulosic fibers and fillers rejected during the pulping or paper making process. Most sludges are dewatered and discharged into landfills or land spread at a ...
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
(
Elsevier Ltd
, 2021 , Article)
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 ...
Metal-organic frameworks as a platform for CO2 capture and chemical processes: Adsorption, membrane separation, catalytic-conversion, and electrochemical reduction of CO2
(
MDPI
, 2020 , Article Review)
The continuous rise in the atmospheric concentration of carbon dioxide gas (CO2) is of significant global concern. Several methodologies and technologies are proposed and applied by the industries to mitigate the emissions ...
Enhancing the production of biogas through anaerobic co-digestion of agricultural waste and chemical pre-treatments
(
Elsevier Ltd
, 2020 , Article)
Large amounts of agricultural solid wastes (ASWs) and animal dung are produced annually causing serious environmental problem that requires proper treatment. The present study proposes a strategy for optimizing the anaerobic ...
Prediction of biogas production from chemically treated co-digested agricultural waste using artificial neural network
(
Elsevier Ltd
, 2020 , Article)
The present study evaluates the effect of co-digestion of agricultural solid wastes (ASWs), cow manure (CM), and the application of chemical pre-treatment with NaHCO3 on the performance of anaerobic digestion (AD) process. ...
Solar oxidation of toluene over Co doped nano-catalyst
(
Elsevier Ltd
, 2020 , Article)
Cobalt (Co) co-doped TiO2 photo-catalysis were synthesized, characterized and tested toward solar photocatalytic oxidation of toluene (TOL). A multi-technique approach was used to characterize and relate the photo-catalytic ...
