Raman spectra obtained from pulp samples 4 to 13 are shown in Figures 2 to 4. For these samples, pulping and bleaching processes produced changes in the 850 to 1850 cm-1 spectral region. The features in these spectra are typical of lignocellulosic materials (authors unpublished work). 

This second series of techniques monographs will cover a number of radiochemical techniques which have not been reviewed elsewhere. Plans include revision of these monographs periodically as new information and procedures warrant. The reader is therefore encouraged to call to the attention of the authors any published or unpublished material on rapid radiochemical separations which might be included in a revised version of the monograph. 

I am greatly obligated to my colleagues and associates at the National Institutes of Health who contributed experimentally, conceptually, and editorially to this chapter. Special thanks are due to Drs. L. A. Cohen, E. Gross, and W. B. Lawson. Dr. C. B. Anfinsen, National Heart Institute, and Drs. A. Berger, A. Patchornik, and M. Sela from the Weizmann Institute were extremely helpful in making unpublished material available prior to publication. To them and many other cooperative authors I extend my sincere thanks. 

The author is grateful to Professor W. D. Ollis and Professor H. G. Viehe for the use of unpublished material and thanks Professor W. D. Ollis, Dr. J. F. Stoddart and Mr. M. Bailey for reading the manuscript and providing many constructive suggestions. 

Extensive literature has been published on blanket and selective CVD-W, in which a vast amount of (sometimes conflicting) information can be found. What is clearly needed is a book where all relevant and pertinent material is gathered in a condensed format. It is the intention of this book to provide such a compilation of the literature with emphasis on the material which has appeared in the last 10 years. In addition, unpublished material obtained in the laboratory of the author is included. After reading this work, the reader will have all the necessary background to bring up, fine tune and maintain successfully a CVD-W process in a production line. Others seeking a quick overview of the current status of CVD-W will also benefit from this book. 

The author gratefully acknowledges the valuable advice in the update of Sections 6.6.5 (Mutagenic Effects) and 6.6.7 (Teratogenic Effects) provided by E. Gebhart, the hitherto unpublished material by M. Anke, and the continuous help in literature searches by the Central Library of the Research Center Juelich, Director R. Ball. 

All work contributed to this book set is new, previously-unpublished material. The views expressed in this book are those of the authors, but not necessarily of the publisher. 

I apologize to authors inadvertently misquoted and will attempt to correct errors in any future editions. As it is difficult to locate many references dealing with topics discussed in this text, I solicit comments and any pertinent information that may be useful for correction of errors or for the preparation of further editions and wish to thank those who have already provided me with manuscripts, reprints, unpublished material, suggestions, and assistance in preparing this present manuscript. Ultimately, of course, I stand responsible for the conclusions and statements made in this text. 

Acknowledgement. The author wishes to thank Professor D. Arigoni (ETFI, Zurich) for many enlightening discussions, copies of Ph. D. theses, and unpublished material which assisted in the preparation of this review. 

Resistance to corrosion Most authors who compare resistance to corrosion of electroless nickel with that of electrodeposited nickel conclude that the electroless deposit is the superior material when assessed by salt spray testing, seaside exposure or subjection to nitric acid. Also, resistance to corrosion of electroless nickel is said to increase with increasing phosphorus level. However, unpublished results from International Nickel s Birmingham research laboratory showed that electroless nickel-phosphorus and electrolytic nickel deposits were not significantly different on roof exposure or when compared by polarisation data. 

In addition to providing a survey of previous studies, it is also the purpose of this chapter is to explore new avenues of potential applications to various electrochemical phenomena. A condensed theoretical background is first presented, and followed by a Markovian treatment of selected processes and phenomena of interest to electrochemists, electrochemical engineers, electrochemical technologists, and technical managers involved with electrochemical plants. Multidimensional analysis is excluded, however, from this essentially whetting the appetite exercise. Material in Section V relies heavily on author s personal (and hitherto unpublished) research. The presentation, although by no means exhaustive, intends to focus on basic concepts, potential utility and new horizons, rather than to pursue completeness. 

Figure 18 shows the temperature dependence of the proton conductivity of Nafion and one variety of a sulfonated poly(arylene ether ketone) (unpublished data from the laboratory of one of the authors). The transport properties of the two materials are typical for these classes of membrane materials, based on perfluorinated and hydrocarbon polymers. This is clear from a compilation of Do, Ch 20, and q data for a variety of membrane materials, including Dow membranes of different equivalent weights, Nafion/Si02 composites ° ° (including unpublished data from the laboratory of one of the authors), cross-linked poly ary lenes, and sulfonated poly-(phenoxyphosphazenes) (Figure 19). The data points all center around the curves for Nafion and S—PEK, indicating essentially universal transport behavior for the two classes of membrane materials (only for S—POP are the transport coefficients somewhat lower, suggesting a more reduced percolation in this particular material). This correlation is also true for the electro-osmotic drag coefficients 7 20 and Amcoh...

The author wishes to thank D. R. Alcoba for his helpful comments and for his generous permission to use the material of his thesis and in particular for allowing her to report here some of his unpublished results. The author also thanks Prof. L. M. Tel and Dr. E. Perez-Romero for their helpful discussions. The author acknowledges financial support from the Ministerio de Ciencia y Tecnologia under project BFM2003-05133. 

In the case of a so-called zero-order reaction, i.e., one whose reaction rate is independent of the concentration of the reacting materials throughout the reaction, violation of the similarity of the concentration field and temperature field as a result of heat transfer to the outside, which does not have an analogue in diffusion, still does not over-complicate the problem. In this particular case we were able to follow in detail the effect of the heat transfer on the entire distribution of the temperature in the flame and on the propagation rate. In our approximation the activation heat is much larger than ETth, and the results of this more detailed investigation confirm all of the formulas derived above (unpublished work by the author, 1938). 

In summary, the development of a well-balanced reply to an inquiry involves the use of published materials in the same manner as that conducted in an academic or clinical setting. In an industry setting, PI information and unpublished data on file with the company are used. In addition, the information communicated must be scientifically accurate, balanced, supported by appropriate literature, and should not include the author s editorial perspectives. 

The material of this book refers to various fields of chemistry, to some mathematics and to numerous experimental works. Therefore, it was not the aim to present an exhaustive list of the appropriate references. Preferably cited are the works that seemed stimulating, representative and thorough. A few interesting older studies concerning the methods were published only in Russian and are not easily accessible here are presented some details of them. Also included are some yet unpublished results obtained by the author and his co-workers, which contribute to the analysis of the published data and of the conventional concepts. 

Hydrolysis is a mild degradation method for characterizing humic substances. It is believed that hydrolysis products may be closely related to the starting materials of humic substances, as mentioned later. Hydrolysis studies of lake humic substances were conducted by several authors (Ishiwatari, 1967a, 1970 Kemp and Mudrochova, 1973 Bourbonniere, 1979 Bourbon-niere and Meyers, unpublished) and many compounds were detected in their hydrolysates.

All readily accessible literature has been examined, including references which have appeared up to, and including, Volume 97 of Chemical Abstracts (December 1982), and some unpublished data (mainly from the author s laboratory) have been included. Because of the subjectivity inherent in choosing material for inclusion in this survey, it is possible that some important contributions have been unintentionally overlooked, for which the author expresses his sincere apologies. 

The authors would like to express their warm gratitude to the many students, colleagues, and coworkers who, during the preparation of this chapter, have supplied helpful comments, preprints of unpublished work, background material for figures, etc. Their encouragement is much appreciated. Special thanks are due to Drs. R. J. P. Williams and G. B. Jameson, who critically read and commented on an early version of the chapter. 

This is not a review chapter in the usual sense. An appreciable amount of the material describes heretofore unpublished work of the authors. In particular. Sections II.E and IV.E include previously unpublished work of Hoye and Stell, and Section IV.B includes new quantitative results of Patey and Stell. On the other hand, we have made no attempt to survey the open literature concerning our subject. (A splendid review of material that overlaps substantially with our own has recently been given by Wertheim. ) Our specific objectives have been as follows ... 

A detailed presentation of all published and unpublished data concerning ACECs and CEC-ACEC compositions is almost impossible within a framework of a review having a limited size. Nevertheless the authors hope to have described the ways of improving the properties of a definite class of polymeric materials by means of an appropriate synthesis of monomers characterized by a differentiated structure of various epoxy groups in the molecule.
