  • Synthetic organic chemistry is equivalent to systematic making and breaking chemical bonds of which the manipulation of carbon-carbon bonds plays an extraordinary role in construction of an organic molecule. Traditionally this chemistry was carried out in organic solutions, however, water or partially aqueous solvents gain more and more significance in organic synthesis recently. To attempt a comprehensive description of this field would be a hopless venture these days, and this chapter gives only examples of the most important ways of carbon-carbon bond formation in aqueous media. ...

  • It is traditional to begin books about polyurethanes by defining the class of polymers that has come to be known as polyurethanes. Unlike olefin-based polymers (poly- ethylene, polypropylene, etc.), the uniqueness of polyurethane is that it results not from a specific monomer (ethylene, propylene, etc.), but rather from a type of reaction, specifically the formation of a specific chemical bond. Inevitably, the discussion in traditional books then progresses to the component parts, the produc- tion processes, and ultimately the uses.

  • 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.

  • Chemical reactions take place due to the redistribution of electron density among the reacting partners. Focusing on changes in electron density, which accompany the breaking and forming of chemical bonds, instead of the changes in the wave function accompanying them, allows us to use the ‘‘classical’’ three-dimensional language. Conceptual density functional theory (DFT) quantifies the possible responses of the system to various changes in density.

  • We build a three-factor term-structure of interest rates model and use it to price corporate bonds. The first two factors allow the risk-free term structure to shift and tilt. The third factor generates a stochastic credit-risk premium. To implement the model, we apply the Peterson and Stapleton (2002) diffusion approximation methodology. The method approximates a correlated and lagged-dependent lognormal diffusion processes. We then price options on credit-sensitive bonds.
