Journal of inclusion phenomena and molecular recognition in chemistry, 1995
Molecular sieves are crystalline materials with open framework structures. Of the almost two billion pounds of molecular sieves produced in 1990, 1.4 billion pounds were used in detergents, 160 million pounds as catalysts, and about 70 million pounds as adsorbents or desiccants [1].

The problem of launching rockets to explore conditions in interplanetary space formed the subject matter of a previous note by the author. In this note further aspects of such exploration by probes are considered.The orbits considered in the previous note were elliptic, and touched the orbit of the Earth at the conclusion of each journey around the Sun.

Abstract Ever since the time when Copernicus advanced, with convincing logical argument, the theory that it is the earth that revolves round the sun and not the sun that moves round the earth, the problem of the distances of the stars has exercised a fascinating hold upon the attention of astronomers.

Robotic space probes usually do not look like people or animals. Rather than resembling the human-looking science fiction movie robots C3PO and Data, they have more in common with the squat, cylindrical R2D2. Like this famous robot from Star Wars, our spacecraft normally do not sport arms, legs, eyes and ears as we do, but they nevertheless function ...
