Bioactive compounds from natural sources Isolation, characterisation and biological properties.

When temperatures are low enough, every substance in thermal equilibrium must become ordered. Since some materials remain fluid to the lowest temperatures, it is a fascinating question as to how this ordering can take place. One possibility is the formation of a superfluid state, in which there is macroscopic quantum order-effectively quantum mechanics in a tea-cup. The author begins Basic Superfluids with these ideas. The book assumes some knowledge of quantum, statistical and thermal physics, and builds on this background to give a readable introduction to the three superfluids of low temperature physics. It introduces the topic to final-year undergraduates or starting postgraduate students.
