Natural zeolites form where volcanic rocks and ash layers react with alkaline groundwater.
2.
This resulted ( according to both Deffeyes and John McPhee ) in the founding of the natural zeolite industry.
3.
"' Clinoptilolite "'is a natural zeolite comprising a microporous arrangement of silica and alumina tetrahedra.
4.
This hygroscopic property coupled with an inherent exothermic ( energy releasing ) reaction when transitioning from a dehydrated to a hydrated form make natural zeolites useful in harvesting waste heat and solar heat energy.
5.
Further development of this approach led to a new direction in NMR spectroscopy associated with the problems of heterostructured systems such as highly porous crystals and minerals, metal organic sorbents, biopolymers, etc . Having deep knowledge of various sorbents'properties, he succeeded in attracting the attention of Soviet authorities to natural zeolites as a means to overcome the consequences of Chernobyl accident in 1986.
