The use of a three dimensional crystalline superlattice as a host for cluster synthesis adds several important dimensions to the design of semiconductor quantum confined structures. Cluster geometry and size distribution are controlled by the topography of the three dimensional host surface, making it possible to create semiconductor quantum superlattices. Novel, normally very unstable, nanosized clusters can be synthesized via encapsulation and coordination to the host framework. The use of large three dimensional surface areas permits studies of cluster interactions over a wide range of concentrations and at relatively high optical densities. Cluster electronic properties can be altered by varying the dielectric and charge properties of the nanoporous host. In addition to single crystals, the porous glasses add new possibilities for following the chemistry involved in forming small semiconductor particles, as well as determining their photophysical properties.

Metal Nano 3D Superlattices Unique view on producing metal nano 3D superlattices by differing their morphologies, crystalline structures, chemical, and physical properties After presenting an overview on the various factors involved in producing metal 3D superlattices called supracrystals by differing their morphologies, crystalline structures, chemical, physical, and intrinsic properties, Metal Nano 3D Superlattices: Synthesis, Properties, and Applications reveals the existence of new materials with unexpected properties. Readers will gain insight into the various approaches on the production and on the specific properties of nanocrystals self-assembled in 3D superlattices also called colloidal crystals, supra or super crystals. These properties open up new avenues of research and potentially aiding in major progress. Overall, the work reviews the progress of and gives perspective on assembled nanocrystals, with a concentrated focus on self-assemblies of metal nanocrystals. Sample topics covered by the highly qualified and internationally awarded author include: Syntheses of nanocrystals with low size distribution. The wide variety of self-assembled nanocrystals in 3D superlattices strongly depends on an impressive number of parameters. The intrinsic chemical and physical properties of 3D superlattices of nanocrystals opens the way to the discovery of unexpected properties. This concerns growth processes, coherent breathing of in 3D superlattices, electron transport through thick assemblies, etc. A strong analogy between atomic crystals and 3D superlattices of nanocrystals emerge: incompressible nanocrystals and coating agents act as mechanical springs holding together the nanocrystals and replace respectively, in atomic crystals, atoms and atomic bonds. The intrinsic chemical and physical properties of nanocrystals and their assemblies depend on their crystalline structures called nanocrystallinity. Collective properties due to dipolar interactions between nanocrystals are pointed out. Water soluble suprastructures act as efficient universal nanoheaters. In addition, reconstruction near the cytoplasmic membrane in tumor cells of nanocrystal self-assemblies takes place opening various biomedical applications. The physical (optical, magnetic, electronic, vibrational) properties of isolated nanocrystals remain present in addition to the intrinsic and collective properties. This allows to benefit from the unique properties of nanocrystals while avoiding their potential size-related risks in future applications. Metal Nano 3D Superlattices offers a deep dive into their synthesis, chemical and physical properties, and applications and is an essential resource for inorganic chemists, materials scientists, physical chemists, surface chemists, and medicinal chemists conducting research related to or involved in the practical application of the topics covered within.

Self-assembly is one of the key concepts in contemporary soft condensed matter. It is an umbrella term which encompasses the various modes of spontaneous organization of micrometer-and submicrometer-sized particles into ordered structures of various degrees of complexity, yet it often relies on remarkably simple interactions and mechanisms. Self-assembly is one of the key principles used by nature to construct living matter, where it frequently takes place in a hierarchical fashion. This book contains the lectures from the Enrico Fermi summer school: Soft Matter Self-assembly, held in Varenna, Italy, in June and July 2015. The primary aim of the school was to cover the most exciting modern aspects of self-assembly in soft condensed matter physics, and to enable Ph.D. students and postdocs to engage with some of the most exciting and current topics in the physics of colloids through a series of mini-courses and seminars hosted by leading figures in the field. Subjects covered include: colloids with directional bonding; pathways of self-organization; self-assembly hydrodynamics; polymer structure and dynamics; liquid-crystal colloid dispersions; and self-organizing nanosystems. The proceedings also include two reprints from Reviews of Modern Physics, and will be of interest to both students and experts in the field.

Bimetallic nanoparticles, also called nanoalloys, are at the heart of nanoscience because of their ability to tune together composition and size for specific purposes. By approaching both their physical and chemical properties, Nanoalloys: Synthesis, Structure & Properties provides a comprehensive reference to this research field in nanoscience by addressing the subject from both experimental and theoretical points of view, providing chapters across three main topics: Growth and structural properties Thermodynamics and electronic structure of nanoalloys Magnetic, optic and catalytic properties The growth and elaboration processes which are the necessary and crucial part of any experimental approach are detailed in the first chapter. Three chapters are focused on the widely used characterization techniques sensitive to both the structural arrangements and chemistry of nanoalloys. The electronic structure of nanoalloys is described as a guide of useful concepts and theoretical tools. Chapters covering thermodynamics begin with bulk alloys, going to nanoalloys via surfaces in order to describe chemical order/disorder, segregation and phase transitions in reduced dimension. Finally, the optical, magnetic and catalytic properties are discussed by focusing on nanoparticles formed with one element to track the modifications which occur when forming nanoalloys. The range and detail of Nanoalloys: Synthesis, Structure & Properties makes it an ideal resource for postgraduates and researchers working in the field of nanoscience looking to expand and support their knowledge of nanoalloys.
