  • This first part is concerned with processes in which the kinetic behaviour of a gaseous phase is rate-determining. The range of processes includes some which are carried out in vacuum systems in which Knudsen or free evaporation occurs from a condensed phase, to transport reactions where a chemical reaction occurs between a solid and the gaseous phase to produce molecular species containing some or all of the elements occurring in the solid phase.

  • enzymes are powerful biological catalysts that are essential for the proper maintenance and propagation of any organism. these properties make them excellent candidates as therapeutic targets to combat diseases of either genetic or pathogenic origin. in this regard, one goal of molecular medicine is to develop and implement effective agents that can modulate the activity of various enzymes involved in essential biological pathways. the process of developing and characterizing these small molecules, i.e., rational drug design, often requires a priori knowledge of the enzyme in question....

  • Cellobiohydrolases (exocellulases) hydrolyze cellulose processively, i.e. by sequential cleaving of soluble sugars from one end of a cellulose strand. Their activity generally shows an initial burst, followed by a pronounced slowdown, even when substrate is abundant and product accumulation is negligible.

  • We live in the age of biology—the human and many other organisms’ genomes have been sequenced and we are starting to understand the function of the metabolic machinery responsible for life on our planet. Thousands of new genes have been discovered, many of these coding for enzymes of yet unknown function. Understanding the kinetic behavior of an enzyme provides clues to its possible physiological role. From a biotechnological point of view, knowledge of the catalytic properties of an enzyme is required for the design of immobilized enzyme-based industrial processes.

  • Crystallization is one of the most ancient and interdisciplinary topics of research known to mankind. Crystals can be organic or inorganic and may be produced from melts, liquid solutions, vapors or even in solid state. Notwithstanding its inherently high complexity, the crystallization process is part of our everyday lives, from ice making in our homes to the most state-of-the-art chemical and electronic industry.

  • This book is an introduction to the quantitative treatment of chemical reaction engineering. The level of the presentation is what we consider appropriate for a one-semester course. The text provides a balanced approach to the understanding of: (1) both homogeneous and heterogeneous reacting systems and (2) both chemical reaction engineering and chemical reactor engineering. We have emulated the teachings of Prof. Michel Boudart in numerous sections of this text.

  • The significant research in adsorption in the 70s through the 90s could be attributed to the discovery of many new porous materials, such as carbon molecular sieve, and the invention of many new clever processes, notably Pressure Swing Adsorption (PSA) processes. This evolution in adsorption research is reflected in many books on adsorption, such as the ones by Ruthven (1984), Yang (1987, 1997), Jaroniec and Madey (1988), Suzuki (1990), Karger and Ruthven (1992) and Rudzinski and Everett (1992).

  • Three-phase fixed-bed reactors are very often encountered in industrial applica- tions for carrying out different chemical reactions between gaseous and liquid reactants on porous catalysts, in processes such as, hydrogenation, hydrotreating, purification, the Fischer–Tropsch synthesis, and in many others. These processes form the basis for production of a large variety of intermediate and ultimate products in refinery, bulk and fine chemistry, in manufacture of monomers, sol- vents, pharmaceuticals, fragrances, fuels, food additives, etc....

  • One of the key economic functions of credit institutions is to convert short- term deposits into long-term loans. Depending on the scale of this maturity transformation – which essentially determines the risk arising from a bank’s balance sheet structure – sharply fl uctuating market interest rates can have a considerable impact on banks’ earnings and on their capital base. The increas- ing complexity of markets makes effective processes for measuring and man- aging interest rate exposure an essential business requirement for credit insti- tutions.

  • The 3¢-processing of viral DNA extremities is the first step in the integra-tion process catalysed by human immunodeficiency virus (HIV)-1 integrase (IN). This reaction is relatively inefficient and processed DNAs are usually detectedin vitro under conditions of excess enzyme. Despite such experi-mental conditions, steady-state Michaelis–Menten formalism is often applied to calculate characteristic equilibrium⁄kinetic constants of IN.

  • The aim is that the pupils are able to transform the knowledge and methodology they have achieved with animation to other learning processes such as video productions and essay writing. Through the work with animation, the children will get to know storytelling, create an awareness of the moving picture language, and develop an ability to distinguish critically. Animation includes different types of aesthetic learning processes and is best suited for processoriented teaching methods.
