Once the microsphetes begin to jump about in Brownian movement in the solution, some of them collide with each other. What should happen when two approximately 105-cm metal spheres collide Many aspects of colloidal chemistry— and hence of molecular biology, including the electrochemical basis of the stability of blood and the forming of clots—are illuminated by a consideration of this subject. 

Cementation, the process by which a metal is reduced from solution by the dissolution of a less-noble metal, has been used for centuries as a means for extraction of metals from solution, and is probably the oldest of the hydrometallurgical processes. It is also known by other terms such as metal displacement or contract reduction, and is widely used in the recovery of metals such as silver, gold, selenium, cadmium, copper and thallium from solution and the purification of solutions such as those used in the electrowinning of zinc. The electrochemical basis for these reactions has been well established414 and, as in leaching reactions, comprises the anodic dissolution of the less-noble metal coupled to the cathodic reduction of the more-noble metal on the surface of the corroding metals. Therefore, in the well-known and commercially exploited44 cementation of copper from sulfate solution by metallic iron, the reactions are...

The two major types of localized corrosion discussed are pitting corrosion, and crevice corrosion including filiform corrosion. In spite of the different morphological appearance of these two types of corrosion (Figure 6.15), the electrochemical basis of these two types are almost the same. The difference may rise from different causes in the initiation step of pitting or crevice corrosion.25...

People living in cold-climate countries where there is plenty of snow are advised not to heat their garages in the winter. What is the electrochemical basis for this recommendation ... 

D25.12 Corrosion is an electrochemical process. We will illustrate it with the example of the rusting of iron, but the same principles apply to other corrosive processes. The electrochemical basis of corrosion that occurs in the presence of water and oxygen, is revealed by comparing the standard potentials of the metal reduction, such as... 

Hills and Kinnibrugh (47) have reported some work which is on a sound electrochemical basis, but the evidence for e"aq is much less direct. 

An appreciation of the physico- and electrochemical basis of SPR sensing [61,62] requires a basic understanding of total internal rehection (TIR), evanescent wave, and surface plasmon theory. Figures 7.3 and 7.4 illustrate the basis of the SPR-based sensor, Biacore. ... 

Electrochemical Basis for Cathodic Protection Criteria The corrosion rate of a steel structure tends to zero when it is polarized to the equilibrium potential because the rate of forward and reverse reactions becomes equal at this potential. For a neutral electrolyte, the calculated potential for the reaction of Fe is —0.59 V (versus saturated hydrogen electrode, SHE), which corresponds to —0.90 V (versus Cu-saturated CUSO4 electrode), not much varied from —0.85 V... 

Despite the enormous amount of biochemical knowledge that has accumulated over the past one hundred years, we remain generally ignorant concerning the molecular mechanisms associated with the major diseases that still afflict mankind. None of them (with the possible exception of diabetes) are associated with obvious derangement of an important metabolic pathway. One cannot help but wonder if classical biochemical knowledge is deficient in crucial areas. The interpretation of metabolism on an electrochemical basis introduces a new dimension and raises the question of whether disease states may be related to disorders of fundamental electrochemical mechanisms, associated with the living state.
