Nanoparticles: advances in synthesis, characterization, theoretical modelling and applications

Recent advances in the synthesis of nanoparticles, and in atomic-scale characterization, coupled with insights from theoretical modelling, have opened exciting possibilities to tailor nanoparticles for many applications, such as catalysis, plasmonics, sensors, magnetism, and biomedical applications.

Scope:

Nanoparticles are attracting much interest for both fundamental scientific reasons as well as for practical applications. In studying their fundamental properties, chemist, physicists, and materials scientists meet. Their properties are strikingly different from those of the corresponding macrocrystalline materials, and based on that applications can be found in fields as diverse as biomedical applications, environmental sciences, optics, electronics and catalysis. Important recent progress is due to advances in controlled assembly of nanoparticles, both by wet-chemical as well as by physical preparation techniques, impressive progress in the resolution of characerisation techniques, offering more and more the possibility to study the formation and functionality of these nanoparticles in situ, coupled to important developments in the field of computatonal chemistry and physiscs, allowing to increasingly understand the fundamental basis of their properties.

This symposium builds on last years success and will bring together again leading experts on advanced techniques for nanoparticle synthesis, in order to promote cross fertilization and to inspire progresses in the control of nanoparticle size, shape, composition and functionalization as well as in the fabrication of nanopartucles with controlled morpmplex morphologies and composition. Characterization techniques with high spatial resolution, spectroscopic capability and chemical sensitivity are an essential tool not only to investigate the output of the synthesis procedures but also to elucidate the structure-property relationships of these particles. This interdisciplinary forum will be completed by the participation of renowned experts in theoretical modelling and simulation of NPs structure and properties, which is of paramount importance both for understanding atomic and electronic structure and to predict non- trivial unexpected behaviour and new phenomena. The symposium will include also a few selected experts on functionality and practical applications of these nanomaterials. Given the “hot topic” nature of the symposium and the unique interdisciplinary discussion opportunities it will provide, we expect a numerous and high quality attendance.
