Investigation of the application of aerobot technology at Venus
... solar heating and thermal tides. Thermal tides (diurnal variations in solar heating) result in transfers of mass in the Venus atmosphere, where atmospheric pressure becomes low where the temperature is hot, and vice versa [11]. Thus the sun may impart angular momentum directly into the atmosphere an ...

Adhesion
Adhesion is the tendency of dissimilar particles or surfaces to cling to one another (cohesion refers to the tendency of similar or identical particles/surfaces to cling to one another). The forces that cause adhesion and cohesion can be divided into several types. The intermolecular forces responsible for the function of various kinds of stickers and sticky tape fall into the categories of chemical adhesion, dispersive adhesion, and diffusive adhesion. In addition to the cumulative magnitudes of these intermolecular forces, there are certain emergent mechanical effects that will also be discussed at the end of the article.
