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.

Treatment of Illitic Clays from Latvia with Organic Acids
Naturally occurring clays typically are mixtures of clay minerals and non-clay minerals, such as quartz, feldspar, carbonates, metal oxides and hydroxides.The use of particular clays often depends on their mineralogical composition, because the presence ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...
