In the other market areas, lead naphthenates are used on a limited basis in extreme pressure additives for lubricating oils and greases. Sodium and potassium naphthenates are used in emulsiftable oils, where they have the advantage over fatty acid soaps of having improved disinfectant properties. Catalyst uses include cobalt naphthenate as a cross-linking catalyst in adhesives (52) and manganese naphthenate as an oxidation catalyst (35). Metal naphthenates are also being used in the hydroconversion of heavy petroleum fractions (53,54) and bitumens (55). 

Depth-sensing nanoindentation is one of the primary tools for nanomechanical mechanical properties measurements. Major advantages to this technique over AFM include (1) simultaneous measurement of force and displacement (2) perpendicular tip-sample approach and (3) well-modeled mechanics for dynamic measurements. Also, the ability to quantitatively infer contact area during force-displacement measurements provides a very useful approach to explore adhesion mechanics and models. Disadvantages relative to AFM include lower force resolution, as well as far lower spatial resolution, both from the larger tip radii employed and a lack of sample positioning and imaging capabilities provided by piezoelectric scanners. 

Methacrylates possess many advantages, and alternatives to them are rarely seen in the marketplace. An early example using styrene in a structural adhesive has been reported [26]. The combination of styrene with unsaturated polyester is commonly used as a filler and bonding putty.

Inelastic electron tunneling spectroscopy has been shown to be a useful method for the study of chemisorption and catalysis on model oxide and supported metal catalyst systems. There are in addition a number of proven and potential applications in the fields of lubrication, adhesion (48), electron beam damage (49,50), and electrochemistry for the experimentalist who appreciates the advantages and limitations of the technique. 

In deciding which surface chemistry tools to use for the broad area of adhesion and for adhesive bonding in particular, a number of aspects must be considered. More often than not, a combination of instruments must be used to take advantage of the unique information provided by each method. Table 1 shows some of the important aspects of adhesive bonding and some of the characterization methods... 

Adhesives offer both advantages and disadvantages in comparison with other methods of assembly, some of the most important of which are presented in summary form at the conclusion of this chapter. (The chapter as a whole comprises an introductory section, a summary of theoretical considerations underlying the effective use of this approach, a review of the types and typical compositions of adhesives suitable for bonding plastics ( solvent-based , water-based , hot-melt , and reactive ), requirements and methods for treating the surfaces in preparation for bonding, and a number of examples of the successful use of adhesives.)... 

A variety of techniques is available for joining plastics to themselves or to other materials—mechanical fastening, welding, and bonding with adhesives—and all are used extensively. Each method has both advantages and drawbacks for plastics, bonding might be said to be preferable when they are to be joined with dissimilar materials. 

There was for some years debate over the advantages and disadvantages of electroless copper or nickel for plastics in decorative applications. It was said that since copper was more ductile it would give the better adhesion however, more recent improvements in etching and activation have tended to nullify any...
