Applied Chemistry (PDT177/2)

The book describes the basic principles that relate to field and current inhomogeneities in semiconductors and their kinetics that occur in the regime of negative differential conductances of semiconductors. The book presents the related theory and experiment. It proceeds to give for the first time the experimental methods to observe directly these inhomogeneities within the semiconductor. It analyses in detail the different ranges in which such inhomogeneities occur, when they are stationary and when not and what technical and device application result. The accompanying film on the website demonstrates all related kinetic effects. Information on these effects was previously mostly available indirectly by interpretation of current-voltage characteristics, or by point contact probing along the surface, or by changes in the luminescence spectrum. The material is based on the original papers of the research team of the author, starting in the late 50's and updated to incl. 2008.

Chemistry and Technology of Lubricants describes the chemical components that contribute to the formulation of liquid lubricants followed by discussion of lubricant technology for specific applications. The individual components are described in Part I: Base Fluids and in Part II: Additives. Part I covers the manufacture and properties of the most common base fluid types derived either from mineral oil or by synthesis, including products from natural gas via gas-to-liquid processes. Part II describes the manufacture, mode of action and performance of the additives that are used to supplement and enhance the performance of base fluids. The use of vegetable oils is also included. Part III: Applications covers the major areas of application of liquid lubricants and each chapter is focused on technology requirements specific to the application. The book is completed by Part IV: Performance which describes more generic technology related to aspects of condition monitoring, environmental impact and industry testing.
