Suggestions for Future Work

COj peaks at 790 (a) and 890 K ( ) with no evidence for the presence of CO desorption peaks at any temperature. This 

3) Based on XFS and HREELS data, peak a was believed to be due to che formation of a oligomeric COj species upon adsorption of COj on che surface. The appearance of peak fi was induced by adventitious contamination in the UHV chamber or defect sites in che Ag crystal. 

4) TPD data analysis indicated chat the desorption associated with peak a was a half order process while that related to peak fi was a first order process. 

Although the book appears quite exhaustive, there are a number of areas where more research work is needed to elucidate the subject matter further. Some of the possible areas, as perceived by the authors, are presented below. 

Chapter 4 gives master rheograms for a long list of polymers but, by no means, includes all known thermc lastics. It is, therefore, beneficial to establish the master rheograms for the thermoplastics not considered in the book along with any new polymers, time and again, when they get developed in the future. 

The upgraded master rheograms have been given in Chapter 5 for a handful of polymers. A systematic study can be initiated so that master rheograms of (q X versus (W /M ,) y/MFI can be established for all polymers 

The presented command sequences in Quqrter 7 for developing the qnead-sheet program are given only for visoosity versus shear rate curves. The step by sto procedure is vmy simple and needs to be extended for other rheologit parameters once master curves are established for a long list of polymos. 

Correlations such as those presented in Oiapter 9 can also be established probably finr a number of other parameters. Alttough such work can certainly be undertaken in future, a better effort can be directed toward the establishment of possible master curves when correlating various process, product, and property parametms with MFI. Such master curves are likely to exist, but a consorted effort is often needed to identify the correct normalizing parameter when coalescing sets of curves. 

The method of obtaining process parameters from master rheograms has been given only for a limited number of cases in Chapter 8. The idea was only to demonstrate the procedure and hence it was limited to only a few processing techniques and that too only to selected processing parameters within the treated processing technique. Extensions of these ideas to other processing parameters would be more than welcome as it would increase the utility value of the presented unification approach. 

More attention should be attached to the problem of /3-PdH involvement in the catalyzed reaction. Careful studies should reveal whether the /3-PdH phase is formed or decomposed under specified reaction conditions. Surface fugacity of hydrogen in the reaction conditions is difficult to predict, and the presence of a reactant hydrocarbon and/or solvent may inhibit/or accelerate the process of incorporation of hydrogen into the bulk of Pd. Another problem is to verify the recent suggestion as to the formation of Pd hydride also in the case of very small Pd particles. 

In conclusion, irrespective of the relevance of the experiment of Fleisch-mann and Pons (224), palladium should remain an important objective of fundamental and technological studies, certainly in the field of heterogeneous catalysis.

Development of high-temperature proton exchange membranes and catalysts for HT-PEMFCs are equally important in terms of the long-term sustainability of fuel cell technology and commercialization. Based on a review of the literature as well as our understanding, we would like to suggest several future research topics for high-temperature catalyst development

Subsequently, we arranged to have him visit our laboratories in the Chemistry Department at McGill (how simple and unsophisticated were our methods and equipment then ). Suffice it to say that we had a stimulating session with him, discussing our research on emulsion polymerization and obtaining many valuable suggestions for future work. His special contribution then, as is the case even now, was that he was aware of the wide spectrum of polymer research which was being carried out in all parts of the world, and could immediately refer you to the literature or to people who could answer your questions. 

There is clearly a strong need for further developments of analytical schemes for description of turbulent reacting flows. Based on the authors work, as summarized in this chapter and also recent contributions by others, there are some suggestions for future work. These suggestions are outlined briefly in this section together with a projection of achievements within the foreseeable future. 

In this chapter, we review the current status of doping of SiC by ion implantation. Section 4.2 examines as-implanted depth profiles with respect to the influence of channeling, ion mass, ion energy, implantation temperature, fluence, flux, and SiC-polytype. Experiments and simulations are compared and the validity of different simulation codes is discussed. Section 4.3 deals with postimplant annealing and reviews different annealing concepts. The influence of diffusion (equilibrium and nonequilibrium) on dopant profiles is discussed, as well as a comprehensive review of defect evolution and electrical activation. Section 4.4 offers conclusions and discusses technology barriers and suggestions for future work. 

Section 18.2 gives a very brief introduction to sialons. Section 18.3 outlines the challenges to be overcome in order to make toughened and strengthened sialon products. Progress in developing sialon composites forms the main part of this chapter and is discussed in section 18.4, which deals with a/p-sialon composites, particle/whisker-reinforced sialons, and fibre-reinforced sialons. In the final section, several conclusions and suggestions for future work are summarised. 

The aim of the present review is (1) to outline the experimental techniques used to explore the primary radiation induced defects in nucleic acid constituents in the solid-state, (2) to provided an updated review of what is currently known about these primary induced radiation defects in DNA, (3) to consider the transformations the primary radicals undergo in order to look at biologically relevant lesion such as strand breaks, (4) to see how theoretical calculations are currently being used to assist in making free radical assignments, and finally, (5) to look at unsolved problems and make suggestions for future work. 

In the discussions above about the complex systems studied, there were comments suggesting that further studies would be helpful. These suggestions for future work are collected below. 

Sections 2 and 3 are concerned mainly with electrochemical reactions in single solvents, and electrode reactions occurring in mixed solvents are covered in Secs. 5-7. The chapter concludes with suggestions for future work. 

Final Submission of Project, Week 12. In this final milestone of the GOLum project, the team submits to the instructor a binder containing all materials related to the project, including the audience description, the description of the presentation forum, the updated annotated bibliography, paper and/or electronic copies of all material presented to the audience, presentation assessments, analysis of outcomes, and suggestions for future work. 

Note any immediate conclusions and possible suggestions for future work. 

The aim of the present review is first to summarize what is known about the primary radiation induced defects in nucleic acid constituents from detailed EPR/ENDOR experiments, then to explore the use of theoretical calculations to assist in making free radical assignments. The theoretical calculations include estimates of spin densities and isotropic and anisotropic hyperfine couplings which can be compared with the experimental results. In many cases the theoretical and experimental results agree rather well. In other cases there are discrepancies between the theoretical and experimental results. The successes and failures of DFT to calculate spin densities and hyperfine couplings of more than twenty primary radiation induced radicals observed in the nucleobases are discussed. Some unsolved problems and suggestions for future work are also discussed. 

Keeping in mind the immense advantages of sustainable polymers, this book primarily focuses on the processing and properties of different sustainable polymers procured from diverse biorenewable resources. Several critical issues and suggestions for future work are comprehensively discussed in this book with the hope that the book will provide a deep insight into the state of the art of sustainable polymers. We would like to thank the publisher for the invaluable help in the organization of the editing process. 

This book consists of 15 chapters and gives an overview on different kinds of biopolymers, their surface modification, and successful utilization for different applications. It also summarizes the developments made in the area of surface functionalization of biopolymers. A number of critical issues and suggestions for future work are discussed in a number of chapters, underscoring the roles of researchers for the efficient development of new techniques for surface modification through value addition to enhance their use.
