Journal Article
Jackson, & Montenari. (2019). Computer modeling of Zircon (ZrSiO4)—Coffinite (USiO4) solid solutions and lead incorporation: Geological implications. https://doi.org/10.1016/bs.sats.2019.08.005

The structure of zircon, ZrSiO4 is modeled using interatomic potentials. The uranium end-member, coffinite (USiO4) and intermediate solid solutions of zircon and coffinite (UxZr1–xSiO4) are then modeled, allowing the prediction of lattice parameters...

Modelling the concentration dependence of doping in optical materials (2015)
Journal Article
Jackson. (2015). Modelling the concentration dependence of doping in optical materials. IOP Conference Series: Materials Science and Engineering, https://doi.org/10.1088/1757-899X/80/1/012010

As well as understanding the location of dopants in optical materials, it is also important to understand how much dopant can be added to a given material. A method for calculating the maximum concentration of dopants has been developed, and applied... Read More about Modelling the concentration dependence of doping in optical materials.

Study of Eu3+ -> Eu2+ reduction in BaAl2O4:Eu prepared in different gas atmospheres (2015)
Journal Article
