Burebrot [SEP] material used
Burebrot
Burebrot, Bauernbrot, Pain paysan or Pane del nonno () is a bread made in Switzerland. "Bauernbrot" is also made in Germany. Unlike most other breads, which are mainly composed of flour, yeast and water, the "Burebrot" also contains milk.
The bread is made by mixing rye and wheat flour, water, salt, yeast and a leavening agent into a dough, which is formed into a round shape. After 70 to 90 minutes, the surface is cut with a knife
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
