The invention provides a rivet and method of installing the rivet to attach honeycomb material to other materials. The coplanar type cell includes: a semiconductor substrate having a front surface and a back surface; and an anode stack and a cathode stack isolated from each other and formed on the back surface of the semiconductor substrate. By breaking andor preventing the formation of bonds that adhere lens fibers together causing hardening of the lens, the present invention increases the elasticity and distensibility of the lens andor lens capsule. The invention also relates to a method for producing solutions of sulfonated aryl phosphines by reacting the aryl phosphines with oleum, diluting the sulfonation mixture with water, extracting the aqueous solution using an organic solution consisting of an amine, and subsequently carrying out a reextraction using an aqueous solution having an inorganic base.
