Abstract:
Core/shell structured CdS/polydopamine/TiO2 (CdS/PDA/TiO2) ternary hybrids were fabricated by sequentially coating of PDA and TiO2 on CdS nanospheres through dopamine self-polymerization and TBOT hydrolysis and hydrothermal processes. The reaction rate constants of CdS/PDA/TiO2 ternary hybrids toward the degradation of RhB, MB and phenol were more than 3 times higher than those of CdS/TiO2 hybrids. The remarkably improved photocatalytic activity was attributed to enhanced light absorption and charge carrier separation efficiency associated with the introduction of PDA.

The paradox
Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...
