Over the past 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 behavior of some complex systems into a discipline with a solid theoretical foundation and a whole to- boxofnew 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 behavior patterns exhibited by natural and artificial systems on the mesoscale. This second volume of"Topics in Current Chemistry"on Colloid Chemistry, focuses on supramolecular approaches and new approaches towards polymer colloids,also with strong emphasis on biological and biomedical applications. Again topics were chosen which are expected to have broader relevance and to be interesting to a more general readership. The volume opens with a contribution by C.M.Paleos in which new amp- philes are presented which not only self-assemble to micelles or vesicles but also possess the ability to show specific recognition of complementary H-bridge p- terns.Such structures might point a way to a rational addressing of surfaces and supramolecular structures by purely chemical means.

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 great deal of experience in the generation and control of matter with tools that are specific on a scale of some nanometers to micrometers.Modern concepts such as self-organisation,hier- chical set-up of materials,nanoparticles,functional surface engineering,int- facing and cross-talk of complex chemical objects,all of which are now in the toolbox of this 90-year old science. It is the aim of the present issue of"Topics in Current Chemistry"to highlight some of the most attractive recent developments in colloid chemistry which are expected to have broader relevance and to be interesting to a more general readership.The contributions focus both on tools and procedures as well as on potential applications.

Graphitic carbon nitride (g-C3N4) is one of the oldest functional materials reported in literature and has recently had a renaissance as researchers explore the breadth of its functionality. This book explores this active material from its history, structure, preparation, catalytic activity, and applications. This fundamental text is an ideal introduction to this fascinating material and gives a holistic overview of its preparation and potential.
