Engineered nanoparticle–support interaction is an effective strategy for tuning the structures and performance of engineered nanoparticles. Here, we show that tuning the dehydroxylation of kaolinite nanoclay as the support could induce zinc oxide–kaolinite interactions.

Desirable exposure of nanoparticle sites and the geometrical and crystal structure were obtained by tuning the interface interaction

Oxidative degradation of lipids, proteins, food and cosmetics involves a radical-chain reaction with release of free radicals. These free radicals are extremely reactive and can even attack relatively stable molecules like the DNA bases. With a recent rise in diseases associated with increased oxidative stress, a good antioxidant seems t
