Improvement of the photocatalytic activity of ZnO thin films doped with manganese [PDF]

Heliyon, 2023
In the herein report, we synthesized ZnO thin films doped with manganese (Mn). We studied the impact of Mn doping loads (1 %, 3 %, 5 % wt.) on physicochemical properties of the compounds. Furthermore, we presented the photocatalytic efficiency in removal

Photochemical formation of oxetanes derived from aromatic ketones and substituted thiophenes and selenophenes

International Journal of Photoenergy, 2000
The photochemical formation of oxetanes from different heterocycles have been investigated for many years in this laboratory. Thus far, only correlation between quenching effect of the heterocycles and capability of forming oxetanes have been established

Polyploidy promotes divergent evolution across the leaf economics spectrum and plant edaphic niche in the Dianthus broteri complex

Journal of Ecology, Volume 110, Issue 3, Page 605-618, March 2022., 2022
Our results indicated shifts in ecological strategies across Dianthus broteri cytotypes and suggested a powerful role of polyploidy in overcoming constraints for the evolution of plant functional traits. Abstract The evolution of the leaf economics spectrum (LES) is known to be constrained by genetic relatedness but also promoted at small geographical ...
