  • Cloud seeding
    Patent number: 5174498
    Abstract: Long-chain aliphatic alcohols are provided that induce nucleation of ice at temperatures within the range from -8.degree. C. to 0.degree. C., from supercooled water present as small drops and/or in the vapor state, and are useful for seeding supercooled clouds in order to augment rainfall.

  • N-heterocyclic amphiphilic amides
    Patent number: 5047535
    Abstract: The invention relates to novel compounds which are suited for the production of multilayer films which have piezoelectric, and pyroelectric properties, and which provide second harmonic generation. The novel compounds are amphiphilic and it is possible to prepare from same polar single-layer and multi-layer films by depositing them on a substrate. When such substrate is a solid support, polar Z-type Langmuir-Blodgett films are obtained. Upon compression of films of such compounds, at an air/water interface, stable Langmuir monolayers are formed.
