Wilberg

In the mid-1800s, Thomas Wilberger Evans (1823—1897) introduced the practice of using an amalgam of silver, which is a solution-type alloy (mixture) of mercury and silver. (Sometimes tin is also added.) In essence, the mercury is used to cement or bind the silver so that it can be used as a filling for decayed teeth. Due to the toxic nature of mercury, fillings are now made with mercury-free, nontoxic compounds.

With very few exceptions, the natural configuration of lycopene in plants is all-trans. Thermodynamically, this corresponds to the most stable configuration (Emen-hiser et al., 1995 Wilberg and Rodriguez-Amaya, 1995). Upon exposure to high temperatures, light, catalysts, or active surfaces, seven of the double bonds of lycopene can isomerize to the less stable mono- or poly-civ- conformations. Stereoisomeric forms of lycopene have also been described with special emphasis on the light absorption properties of different molecular structures (Zechmeister, 1962).
