Book Description
This book presents and analyzes the influence of small size particles of lead, cadmium and silver sulfide on the properties of nonstoichiometric semiconductors. Important nonstoichiometry aspects in nanostructures are discussed, such as the distribution of sulfur atoms in nanofilms, a non-periodic distribution of the atomic planes in nanoparticles, interdependent changes in crystal structure of nanocrystalline material. Tuning the stoichiometry allows to obtain superionic conductivity and catalytic activity under visible light. The wavelength of the luminescence of nanoparticles changes with the size of the nanoparticles. Various methods to prepare nanostructured sulfides are described. Special attention is given to the hydrochemical bath deposition as a universal method for the synthesis of sulfides as nanofilms, stable colloidal solutions, quantum dots, isolated nanoparticles with a protective shell and heteronanostructures. The effect of nanoparticle size and nonstoichiometry on the band gap, optical and thermal properties of nanostructured sulfides is also considered. The novel applications of sulfide nanoparticles in nanoelectronics, catalysis, nanobiology and nanomedicine are sketched.

Book Description
The book focuses on the thermal transformations of various types of metal chelates, e.g. low molecular weight and polymeric metal chelates, coordination polymers and metal-organic frameworks. It analyzes the major advances and the problems in the preparation of metal oxide materials, mixed-oxide nanocomposites, carbon materials and polymer derived non-oxide nanocomposites by the thermolysis of different metal chelates. It also highlights the influence of the spatial and electronic structure of metal chelates on the mechanism and kinetics of their thermal transformations, and discusses important issues like conjugate thermolysis and computer modelling of the thermolysis process. This book is useful for researchers experienced in thermolysis as well as for young scientists interested in this area of science.

Book Description
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.
