Homogeneous catalysis Homogeneous catalysis In chemistry, homogeneous catalysis is catalysis in a solution by a soluble catalyst. Homogeneous catalysis refers to catalytic reactions where the catalyst is in the same phase as the reactants. Homogeneous catalysis applies to reactions in the gas phase and even in solids. Heterogeneous catalysis is the alternative to homogeneous catalysis, where the catalysis occurs at the interface of two phases, typically gas-solid. The term is used almost exclusively to describe solutions and often implies catalysis by organometallic compounds. The area is one of intense research and many practical applications, e.g., the production of acetic acid. Enzymes are
Happiness is a cigar called Hamlet Happiness is a cigar called Hamlet "Happiness is a cigar called Hamlet" is one of the best remembered British advertising campaigns for a tobacco product. It was a long-running campaign for Hamlet Cigars, lasting on television until all tobacco advertising on television was banned in the UK in 1991. They returned in cinemas in 1996, continuing there until 1999, with the final commemorative advert and the modified tagline, "Happiness will always be a cigar called Hamlet." Commercials used an excerpt from a jazz rendition of Bach's Air on the G String, played by Jacques Loussier and his trio, which is
