Facile method to synthesize magnetic iron oxides/TiO2 hybrid

Therefore, immobilization of TiO 2 on magnetic iron oxide NPs has been investigated intensely due to its magnetic separation properties [28-32]. Indeed, the study of core-shell magnetic NPs has a wide range of applications because of the unique combination of the nanoscale magnetic iron oxide core and the functional titania shell.

The effect of Fe–Ti oxide separation on iron isotopic fractionation

Separation of Fe–Ti oxides during magmatic differentiation plays an important role in controlling Fe isotopic evolution of residual magmas. Titanomagnetite (Tmag) is a common Fe–Ti oxide phenocryst phase in evolved basaltic lavas, but the effect of its separation on Fe isotopic evolution of residual melts remains poorly understood. Here we explore this issue with …
