The flexible joint is an important part in ultra-short-radius drilling tools, and its structural parameters motion characteristics are key factors affecting the success of drilling. In this work, a new type ball cage joint, which applied 5″ 5.5″ cased wells, was proposed based on working principle universal joint. A parameter design method for established according to geometric coordination rel...

Carbon atoms self-assemble into the famous soccer-ball shaped Buckminsterfullerene (C(60)), the smallest fullerene cage that obeys the isolated-pentagon rule (IPR). Carbon atoms self-assemble into larger (n > 60 vertices) empty cages as well-but only the few that obey the IPR-and at least 1 small fullerene (n <or= 60) with adjacent pentagons. Clathrin protein also self-assembles into small full...
