Development of Efficient Supramolecular Photostabilizer for Carotenoids and Retinoids: Analyses and Application Research. [PDF]

J Cosmet Dermatol
ABSTRACT Background Carotenoids and retinol are well known for their potent antioxidant and biological properties in pharmaceuticals, foods, and cosmetics. However, their poor photostability presents a significant challenge that cannot be effectively addressed through simple formulation strategies such as encapsulation.

Functional Polymers Through Mechanochemistry [PDF]

CHIMIA, 2019
Abstract: While coupling mechanical and chemical processes is widespread in living organisms, the idea to harness the mechanically induced dissociation of weak covalent and non-covalent bonds to create artificial materials that respond to mechanical stimulation has only recently gained attention.
