Capacitive Deionization for the Removal of Paraquat Herbicide from Aqueous Solution
(Hindawi, 2021-10-08)In comparison to other conventional methods like adsorption and reverse osmosis (RO), capacitive deionization (CDI) has only been investigated extensively for the removal of inorganic pollutants from water, demonstrating ... -
A Review on Computational Fluid Dynamics Applications in the Design and Optimization of Crossflow Hydro Turbines
(Hindawi, 2021-10-15)In recent years, advances in using computational fluid dynamics (CFD) software have greatly increased due to its great potential to save time in the design process compared to experimental testing for data acquisition. ... -
Catalytic supercritical water gasification of biomass waste using iron-doped alkaline earth catalysts
(Springer Nature Switzerland AG., 2022-05-18)The objective of this study is to optimise the process of supercritical water gasification of rice husk biomass utilising a low-cost catalyst made from alkaline-earth materials. The interactions between catalyst loading ... -
Electrospun carbon nanofibers for use in the capacitive desalination of water
(Elsevier, 2022-12)Capacitive deionization (CDI) has rapidly become a promising approach for water desalination. The technique removes salt from water by applying an electric potential between two porous electrodes to cause adsorption of ... -
Rheological and Physicochemical Analysis of Nonedible Oils Used for Biodiesel Production
(ACS Omega, 2022-10-13)Rheological and physicochemical characteristics of edible oils used for biodiesel production are well established; nonetheless, the rheological and physicochemical characteristics of nonedible oils are yet to be established. ... -
Water defluoridation using Al/Fe/Ti ternary metal oxide-loaded activated carbon by capacitive deionization
(Royal Society of Chemistry, 2023-01-26)Capacitive deionization (CDI) is an environmentally friendly water treatment technology with low energy consumption. For a long time, activated carbon has been a preferred electrode material for CDI owing to its availability, ... -
