A Possible Radiation-Induced Transition from Monazite-(Ce) to Xenotime-(Y) [PDF]
Minerals, 2020 This study examines two pegmatitic monazite samples (2a and 4b, these numbers are related to a previous study) to determine their crystal chemistry and effects of internal radiation damage using synchrotron high-resolution powder X-ray diffraction and electron-probe micro-analysis. Both the huttonite and cheralite substitutions are discussed.

Synthesize of Poly (acrylamide-co-itaconic/TiO2) Nanocomposite for Ce(III) Sorption from Monazite Leachate [PDF]
Journal of Polymers and the Environment, 2021 In this study, Acrylamide (AAM), Itaconic acid (IA) and nano TiO2 were copolymerized using gamma irradiation with 60Co γ-rays at a dose of 25 KGy to form poly (acrylamide-co-Itaconic acid/TiO2) (P(AAM-co-IA/TiO2)). Different compositions of P(AAM-co-IA/TiO2) nanocomposites are prepared and examined for Ce(III) sorption.

High-pressure behavior of gasparite-(Ce) (nominally CeAsO4), a monazite-type arsenate
Physics and Chemistry of Minerals, 2022 AbstractThe high-pressure behavior of the natural arsenate gasparite-(Ce) [Ce0.43La0.24Nd0.15Ca0.11Pr0.04Sm0.02Gd0.01(As0.99Si0.03O4)] from the Mt. Cervandone mineral deposit (Piedmont Lepontine Alps, Italy), has been studied by in situ single-crystal synchrotron X-ray diffraction up to 22.01 GPa.
