Fields of activity

The author is sure that the readers will find ample opportunity to learn from his experience and apply this information to their field of activities. The book aims to provide a bridge between the concept and the application. With this book by his or her side, an engineer should be able to apply better, design better and select better equipment for system needs and ambient conditions. It should prove to be a handy reference to all those in the field of design and application, protection and testing, production, project engineering, project implementation or maintenance, in addition to the sales and purchase of these products. 

The increasing volume of chemical production, insufficient capacity and high price of olefins stimulate the rising trend in the innovation of current processes. High attention has been devoted to the direct ammoxidation of propane to acrylonitrile. A number of mixed oxide catalysts were investigated in propane ammoxidation [1]. However, up to now no catalytic system achieved reaction parameters suitable for commercial application. Nowadays the attention in the field of activation and conversion of paraffins is turned to catalytic systems where atomically dispersed metal ions are responsible for the activity of the catalysts. Ones of appropriate candidates are Fe-zeolites. Very recently, an activity of Fe-silicalite in the ammoxidation of propane was reported [2, 3]. This catalytic system exhibited relatively low yield (maximally 10% for propane to acrylonitrile). Despite the low performance, Fe-silicalites are one of the few zeolitic systems, which reveal some catalytic activity in propane ammoxidation, and therefore, we believe that it has a potential to be improved. Up to this day, investigation of Fe-silicalite and Fe-MFI catalysts in the propane ammoxidation were only reported in the literature. In this study, we compare the catalytic activity of Fe-silicalite and Fe-MTW zeolites in direct ammoxidation of propane to acrylonitrile.

How much detail does a student need to know and how much detail should a textbook then contain This is an almost unsolvable problem because of the diversity of students and their analytical needs. The majority of students will eventually move on into special fields in (bio)chemistry, molecular or systems biology or polymer chemistry. For them mass spectrometry will only be one of the commodities to help them solve their problems, which are defined by their field of activity, not the analytical technique. How much of the basics in mass spectrometry will they need to know Again, this depends on the problem at hand. For many a routine application of commercial instalments and the manufacturers manuals will suffice. However, if the problem is not routine the analytical technique cannot be either. Mass spectrometry is and, most probably, will remain a rather complex technique. To fully exploit its tremendous potential, but, equally important, to avoid its many pitfalls, a deeper understanding of the mechanisms and the technology will be mandatory. This book will, hopefully, help students to lay the basis for this expertise and, once the need arises, allow them to go back to the more specialized literature at a later time. It is in this sense that I hope this book will be a real help to many of them. 

Isabelle Stengers first studied chemistry, then philosophy, which later became her main field of activity (she is presently professor of philosophy of science at ULB). She did her PhD thesis under the direction of Prigogine, on the problem of time.

The high intensity of laser light (lots of photons per cm3) gives significant probability to transitions in which two photons, rather than one, are absorbed. Such two-photon processes are a field of active study. 

It would appear that the study of the diffusion equation subject to a phase change at one boundary is in a relatively satisfactory state, provided simple boundary conditions of the first, second, or third kind are specified. From a mathematical point of view, the interesting features of the problem arise from the nonlinearity, exhibited for all but a few particular boundary motions. A wide variety of approximate and numerical methods have been employed, and it has frequently been difficult for workers in one specialized field of activity to become conversant with similar approaches made by investigators in other areas. It is hoped that the present work will, to some extent, alleviate this problem. 

The restricted space of this introductory article does not allow us to give further attention to Ya.B. s papers on the physical chemistry of combustion and detonation.4 In Ya.B. s own words, the science of combustion and detonation is dear to him because it provided him, at the beginning of his life and career, with a wide-open field of activity both as a theorist and as a bold experimenter. Important problems of a fundamental nature were being solved, problems which were related to important technological applications. The tremendous contribution which Ya.B. made to this science is the pride and showpiece of the Soviet school of combustion. Ya.B. s work on the theory of detonation and combustion was recognized by awarding him the State Prize of the USSR in 1943. 

F or centuries man has attempted to devise an effective process by which combustible materials could be rendered noncombustible or at least fire-resistant, but until about 10 years ago progress in this field was very limited and the effectiveness of the processes was questionable. Back in the days of the Roman Empire, efforts were made to reduce the fire hazard in props, curtains, and decorative-effect materials used in stage and theatrical plays by impregnating the fabrics with fine clay, and at about the same time clay, gypsum, and other types of plaster were used to coat wood, in an effort to make it resistant to fire. Since that time there has been steady progress in the field of fire-resistive and fire-retardant treatment processes, but it has been slow and the field of activity has been rather limited. 

We hope that our general aim may be reached to arouse the interest of the environmental scientist who has not yet much concerned himself with chemometric methods and the use of the tools of chemometrics in his own field of activity.
