Over the last forty years, good old-fashioned colloid chemistry has undergone something of a revolution, transforming itself from little more than a collection of qualitative observations of the macroscopic behaviour of some complex s- tems into a discipline with a solid theoretical foundation and a whole toolbox of new chemical techniques.It can now boast a set of concepts which go a long way towards providing an understanding of the many strange and interesting beh- iour patterns exhibited by natural and artificial systems on the mesoscale. In other words: colloid chemists have acquired a...
