When the Abbe Hauy pointed out the close similarity and probable identity of beryl and the emerald, Vauquelin analyzed them carefully, and found in 1798 that they are indeed identical, and that they contain a new earth, which he named glucina, but which is now known as beryllia The metal was isolated thirty years later by Wohler and Bussy independently. Boron was isolated in 1808 by Gay-Lussac and Thenard in France and by Davy in England by reduction of boric acid with potassium. Although amorphous silicon was prepared by Berzelius in 1824, the crystalline form of it was not obtained until about thirty years later, when Henri Sainte-Clarie DeviUe prepared it by an electrolytic method Aluminum was isolated in 1825 by the Danish physicist, Oersted, and two years later Wohler prepared it by a better method. Successful commercial processes for the manufacture of this important metal were perfected by Henri Sainte-Claiie Deville, by Charles Martin Hall, and by Dr. Paul L. T. Heroult. 

It is a well-known fact that upon covalent immobilization at the surface, the dissociation constant of the acid-base indicator changes by as much as 3 pK units. This shift clearly illustrates the dramatic effect that the interphase has on the ionization equilibria. It is perhaps the most serious problem with optical sensors that the surface concentration of any species is related to its corresponding bulk activity value through an adsorption isotherm which, with the exception of Henry s law, is a highly nonlinear and variable relationship. It is also known (Davies and Rideal, 1963) that the surface pH is different from the bulk value due to the electrostatic repulsion.
