Title: "Strategies and techniques for enhancing the success of crystallization"

Sessions:


T1 - Fundamentals of Crystal Growth
Session Chair: Prof. Maurizio Masi - maurizio.masi@polimi.it

This section aims at cover fundamentals of crystal growth: theory, modeling, and experiments. In particular, we will deal with the nucleation and growth mechanisms of materials formed from solution and vapor, by means of experimental observations and theoretical simulations. Peculiar attention will be paid to the role of crystal surfaces into both formation and growth of strategic materials for the industry, where the relationship between growth process performances and final material properties are today the key factor for the profitability. The structure of the bulk, and crystal/vapor and crystal/solution interfaces, along with their relationships, will also be analyzed in order to better understand the growth processes and the formation of defects in crystals.

Invited speaker:

Carlo Cavallotti, Politecnico di Milano: "Recent advancements in the automation of CVD reactors for the epitaxial deposition of Si and SiC: synergy between modeling and experiments" 
Maria Porrini, SunEdison Semiconductor Company, Merano (Bz): "Latest developments in the Industrial growth of Czochralski Silicon Crystals for the semiconductor industry"

T2 - Low Dimensional Structures: films, wires, dots

Session Chair: Dr. Silvia Rubini - rubini@iom.cnr.it

This session will focus on the growth of low dimensional crystalline materials, such as quantum dots, quantum rings, nanowires, 2D materials and epitaxial 2D layers, and on the various methodologies (including molecular/chemical beam epitaxy, metalorganic vapor phase epitaxy, chemical vapor deposition, atomic layer deposition, but also wet chemical synthesis) utilized for their self-assembly. Emphasis will be specially given to the growth mechanisms and to the study/control of the physical properties of the low-dimensional materials.

Invited speaker:
Dr. Valentina Zannier, Institute of Nanoscience CNR, Pisa: "Catalyst composition tuning: the key for the growth of straight axial nanowire heterostructures"

 
T3 - Organic-Based Materials
Session Chair: Prof. Matteo Masino - matteo.masino@unipr.it


This session is devoted to the growth of organic functional materials, in the form of single crystals, thin films, and heterostructures, also made by coupling organic and inorganic materials to form hybrid systems. Within the large variety of organic molecules, the focus will be on organic semiconductors, in terms of the growth and physical properties studied in view of applications in organic electronics. In addition, we aim at including compounds interesting in the field of biotechnology or, simply, whose affinity with biological systems may be predicted as relevant for the understanding and exploitation of specific interactions.

Invited speaker:

Dr. Tommaso Salzillo, Institut de Ciència de Materials de Barcelona (ICMAB), Spain: "Bulk and thin film polymorphs in nature inspired semiconductors by Raman microscopy"

Dr. Stefano Canossa, Università degli Studi di Parma: "Single-crystal-to-single-crystal transmetalation enables the formation of a metastable MOF"

T4 - Crystalline Materials for Energy
Session Chair: Prof. Francesca Soavi - francesca.soavi@unibo.it
Worldwide efforts are being devoted to promote an efficient use of renewable energy sources and sustainable electric transportation for a fossil fuel-free society. In such scenario, high efficiency energy conversion and/or storage systems like solar cells, fuel cells, and batteries are playing a key role. New materials hold the key to fundamental advances in the development of these devices This session is devoted to recent progresses in the synthesis and characterization of crystalline materials and in their use in energy related technologies.

Invited speakers:
Prof. Thomas Brown, Università di Roma "Tor Vergata": "Key crystalline components for solar energy conversion"
Dr. Sergio Brutti, Università degli Studi della Basilicata: "Structural properties of inorganic materials for lithium-ion batteries and beyond"
Dr. Cristina Tealdi, Università degli Studi di Pavia: "Proton conducting crystals"

T5 - Industrial Crystallization
Session Chair: Dr. Enrico Modena - enrico.modena@polycrystalline.it


The symposium’s aim is to provide some example of industrial applications of crystallization processes with a specific focus on the pharmaceutical sector. Over recent years, a significant growth of interest in solid state properties and industrial crystallization was observed, in order to achieve better control of drugs' characteristics and therefore of their quality.  Research is active on two major topics: on one hand, it is aimed to design and optimize the crystallization procedures to control the polymorphism of the APIs (i.e. to isolate a specific crystalline form):  on the other hand, the control of physical properties of particles (e.g. granulometry, morphology and rheological) appears more and more crucial.

Invited speaker:
Dr. Saverio Nanna, Solida Pharmaceutical Manufacturing, Bologna: "API polymorphism: problem or opportuinity?”

T6 - Crystallization of Biomolecules

Session Chair: Prof. Martino Bolognesi - martino.bolognesi@unimi.it

The spectacular progresses of techniques allowing to produce recombinant proteins, or to isolate ultra-pure biological macromolecules, has stirred a growing interest for crystal growth particularly in the domain of proteins. Besides isolated (globular, water soluble) proteins, the research front line is currently on macromolecular complexes (including multi-protein adducts and protein/nucleic acid complexes) and on membrane proteins, whose handling requires specific techniques as well as new concepts (e.g. cubic phase crystallization). Crystallization screening and robotic methods allow to increase the chance of success in protein crystal growth, opening the field to original biological information (new protein structures), but also to industrial applications in the search for new drugs binding specific biological systems.
