The EsF 3 crystal structure is hexagonal, as in californium(III) fluoride (CfF 3) where the Es 3+ ions are 8-fold coordinated by fluorine ions in a bicapped trigonal prism arrangement. [36] [89] [90] Es(III) chloride (EsCl 3) can be prepared by annealing Es(III) oxide in the atmosphere of dry hydrogen chloride vapors at about 500°C for some 20 ...
Several different approaches have been used to develop robots that have the ability to climb vertical surfaces. One approach mimics the movements of a human climber on a wall with protrusions; adjusting the center of mass and moving each limb in turn to gain leverage.
