Abstract:
Core-shell structured ZSM-5 zeolites (CSSZs) consisting of a micro-macroporous zeolite core and a mesoporous zeolite shell were synthesized by using a bifunctional surfactant containing an alkene group in the hydrophobic tail. The alkene tail and aluminum concentration are the key factors for the formation of the mesoporous shell in CSSZs.

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...

Dehydration Synthesis
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.
