Silver nanoparticles in natural zeolites incorporated into ...

In this study, silver nanoparticles on chabazite, clinoptilolite, and clinoptilolite-stilbite natural zeolites were synthesized. The nanomaterials were incorporated into commercial coatings and afterward, the antibacterial activity was carried out. The zeolites were exposed to the activation step before the ion-exchange process with the precursor.

Using Zeolites To Protein Stabilize White Wines | ACS ...

The use of bentonite fining in the global wine industry causes losses in the range of US$1 billion per year. This work explores for the first time the potential use of natural zeolites as an alternative to bentonite to remove haze proteins from white wines. Wines treated with zeolites were compared to those obtained after fining using two commercial bentonites (Vitiben and Pluxcompact ...
