Adsorption of pepsin by gibbsite and boehmite, non-acid-reactive forms of aluminum hydroxide, was observed and related to the surface area of the adsorbent. Adsorption was pH dependent, with maximum adsorption occurring between pH 2.7-3.3 for gibbsite and pH 2.7-4.3 for boehmite. Electrostatic attra

Surface modification of aluminum was carried out using a new method named electrical discharge alloying. Deposition of titanium contained in electrodes and carbon decomposed from hydrocarbon working fluid occurs on aluminum substrates. With an electrode of a Ti-36mass%Al premixed green compact~ in s
