Interactions between Plants and Rare Earth Oxide Nanoparticles

(Corresponding) Zhang Z.
Topic: 
Nanomaterials in the environmnents applications and effects
Rare earth oxide nanoparticles (REO NPs) can be released into the environment from various application routes, but their effects on the ecosystem are still little known. In this study, we exposed cucumber seedlings to suspensions of La2O3 and CeO2 NPs for 14 d. Phytotoxicity of the two REO NPs was...Read more

Cobalt- and copper-modified coal fly ash nanozeolites for environmental protection applications

(Corresponding) Boycheva S., Marinov I., Lazarova H., Zgureva D., Václavíková M., Popova M.
Topic: 
Nanomaterials in the environmnents applications and effects
Fly ash zeolites (FAZ) are promising materials for adsorbents, ion-exchangers and catalysts. FAZ usually possess a mixed micro-mesoporous structure that facilitates mass transport phenomena through their framework. Due to the transfer of iron spinel oxides and many metal species from the raw...Read more
