Borospherene [SEP] material used
Borospherene
Borospherene (B) is a cluster molecule containing 40 boron atoms. It is similar to buckminsterfullerene, the "spherical" carbon structure, but with a different symmetry. The discovery of borospherene was announced in July 2014, and is described in the journal "Nature Chemistry". Borospherene is the latest in a series of cluster molecules, including buckminsterfullerene (C), stannaspherene, and plumbaspherene. The newly discovered molecule includes unusual heptagonal faces.
Structure.
Borospherene has a unique axis of symmetry (a 180
to cathodically protect metals that are exposed to sea water. A zinc disc attached to a ship's iron rudder will slowly corrode while the rudder stays intact. Similarly, a zinc plug attached to a propeller or the metal protective guard for the keel of the ship provides temporary protection.
With a standard electrode potential (SEP) of −0.76 volts, zinc is used as an anode material for batteries. (More reactive lithium (SEP −3.04 V) is used for anodes in lithium batteries ). Powdered zinc is used in
