The main idea is to provide the phase diagram of binary and ternary alloys at the nanoscale by using nano-thermodynamics. Experimentally, it is extremely challenging to get the phase diagram of nanostructures by calorimetry due to the small mass involved; therefore, the only alternative is to use theoretical methods like nano-thermodynamics.
The goal of this project is to synthesize nanoparticles free of any surface contaminants.
This symposium aims to provide an international forum on the latest developments in nano-alloys research, including the tools used for their study, considering experimental and theoretical approaches. The focus is primarily on the synthesis, characterization and computational modeling of nanoalloys. Nowadays, a complete understanding of the nanoalloys behavior has not been yet achieved. From a theoretical perspective, this requires the use of a vast number of methodologies depending on the size ranges and time scales considered namely: Nanothermodynamics, Density Functional Theory (DFT), Molecular Dynamics (MD) and Metropolis Monte Carlo (MMC) simulations. Experimentally, calorimetry is still challenging at the nanoscale however, electronic microscopy techniques such as in-situ heating experiments using TEM can provide useful data to improve the knowledge on nanoalloys phase stability and phase transition. Finally, latest developments in synthesis should be carefully discussed in order to achieve better control in size, shape and composition. The objective of this Symposium is to bring together theoreticians and experimentalists to share ideas and encourage new collaborations on this topic. By participating in this Symposium, attendees will gain a deep insight into the current state-of-the-art research being carried out in academia, international laboratories and industries working in the field of nanoalloys.
