Green Fuel Combustion Synthesis of CeO2 and Ag/CeO2 Nanoparticles for Photocatalytic and Antibacterial Applications

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Silver‐doped cerium oxide nanoparticles (Ag/CeO2 NPs) were synthesized using Ricinus communis seed extract as a bio‐derived fuel in a solution combustion method. The combustion reaction, carried out at 450°C with AgNO3 and (NH4)2[Ce (NO3)6] as metal precursors, produced CeO2 and Ag/CeO2 NPs.

Preparation and Performance Evaluation of a Self‐Generated Particle Plugging Agent Based on Thermosetting Resin

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT A thermosetting in situ curing resin microsphere system has been developed. It has controllable phase transition time and particle size. This system addresses the current challenges of low strength, shear susceptibility, and short phase transition time in polymer microsphere blockers and thermoplastic particle blockers.

Preparation of MOEAMCl and MAAm Based Hydrogels and Effective Use in Anionic Dye Adsorption

Journal of Applied Polymer Science, Volume 142, Issue 16, April 20, 2025.
ABSTRACT In this study, hydrogels based on [2‐(Methacryloyloxy)ethyl]trimethylammonium chloride (MOEAMCl) and methacrylamide (MAAm) were synthesized for the removal of anionic dyes from aqueous solutions. Following detailed characterization, the use of hydrogels for methyl orange (MO) adsorption was investigated.

Ferroelectric Materials by the Sol-Gel Method

Journal of Sol-Gel Science and Technology, 1997
The sol-gel method is ideally suitable for the preparation of ferroelectric thin films such as LiNbO3, BaTiO3, KNbO3 and PZT. The preparation and properties of polycrystalline, amorphous and single crystal films of these ferroelectric oxides are summarized. The origin of “amorphous ferroelectricity” is discussed.

Combinatorial methods in sol-gel technology

SPIE Proceedings, 2000
Sol-gel processing consists several variable parameters during materials synthesis and post processing steps. The sol-gel synthesis is rather sensitive for the parameters such as pH, temperature, type of catalyst, reaction time etc. However, this sensitivity can be taken as an advantage when developing and studying new materials and their properties ...

Preparation of nanosized CoAl2O4 powders by sol–gel and sol–gel-hydrothermal methods

Journal of Alloys and Compounds, 2009
Abstract Nanosized cobalt aluminate (CoAl2O4) spinel powders were prepared by the sol–gel and sol–gel-hydrothermal methods using aluminum sec-butoxide, cobalt salts and nitric acid as oxides precursors to form sols and gels. The obtained powders were characterized by XRD, DSC–TGA and SEM.

SUPERCONDUCTIVE CERAMICS OBTAINED WITH SOL–GEL METHODS

International Journal of Modern Physics B, 1988
Several sol–gel routes have been considered, studied and developed to produce large quantities of granulates which can be processed to obtain ceramics having good superconducting characteristics. In the considered process a mixture of commercial nitrates is atomized, at room temperature, in a solution 1:1 of Primene JMT and benzene, and a pale blue ...
