2012 ISC Overview

The Laboratory of Crystallographic Studies (CSIC-UGR) organised the 3rd International School of Crystallization (ISC2012, http://www.iscgranada.org/) under the auspices of the International Union of Crystallography through the Crystal Growth and Characterization of Materials Commission. The event took place in the Centre of the beautiful City of Granada, an ideal place to promote close scientific and social interactions between the attendees.

The School was aimed for postgraduate/postdoctoral students as well as research scientists from industry and academia that deal routinely with crystallisation processes but seek fundamental knowledge on the crystallisation phenomena and the behaviour of crystallising solutions. Students from all over the world were invited to learn from top quality international speakers, to hear case study presentations, to watch practical hands-on demonstrations, to participate in round table discussions and to present their research results in the purposely dedicated poster sessions.

ISC2012 covered five days of lectures and practical demonstrations related to the field of the crystallization of foods, drugs and agrochemical compounds, including dedicated sessions on polymorphism and mineral growth.

Organising Committee
  • Prof. Juan Manuel Garcia-Ruiz, Director of the School
  • Dr. Jaime Gómez Morales, Director of the School
  • Dr. Ulrich Griesser
  • Dr. Alfonso Garcia Caballero
  • Dr. Duane Choquesillo Lazarte
  • Dr. José Manuel Delgado López


The turnout of the School was excellent having with 115 participants from 25 different countries, most of which were students (58 students, 50.4 %) and academics (16 academics, 13.9 %), being the rest composed of industrial representatives and exhibitors (Figure 1). The participants were supported by 31 speakers and demonstrators (27.0 %).

A considerable effort was made to provide financial support to as many students as possible. In fact, all of the 26 grant applications were accepted for funding (Figure 2). Remarkably, all the students coming from outside Spain (accounting for 88,9 % of all the granted students) received financial support to attend the School.

Programme of the ISC2012

ISC2012 covered five days of lectures and practical demonstrations carried by 31 selected experts in the field of crystallisation.


Main topics of the ISC 2012

  • Solution properties
  • Nucleation: classical and non-classical approaches
  • Crystal growth kinetics and mechanisms
  • Crystallization routes
  • Crystallization techniques
  • Crystal morphology
  • Mineral textures
  • Polymorphism
  • Hydrates and solvates
  • Crystallization screening
  • Industrial (mass) crystallization
  • Crystallization and law
  • Chirality
  • Biomineralization
  • Cocrystals
  • Mineral growth
  • Special and hot topics on crystallization


The first day of the School dealt with the fundamentals of crystallisation from solution encompassing a revision of phase diagrams, speciation, supersaturation and basic concepts on crystallizing solutions, nucleation theories, crystal growth kinetics and mechanisms, crystal morphology and analytical techniques for monitoring, controlling and scaling-up solution crystallization processes (Figure 3).

The second day of the School focused on both classical and novel crystallisation techniques such as crystallisation in solution vs gel growth, crystallization from melts, supercritical crystallization, high pressure crystallization, the development of robust pharmaceutical crystallization processes and crystallization of lipids in colloidal dispersion techniques (Figure 4).

The morning session of the third day was devoted to discuss the fundamentals of polymorphism, chiral crystallization, engineering cocrystal thermodynamic stability and eutectic points via micellar solubilization and ionization and legal aspects of polymorphs and solvates (Figure 5).

Wednesday afternoon and Thursday were entirelydedicated to a 'Demonstration Fair', at which 22 specialists offered short (20-40 minutes) practical sessions periodically at scheduled times. Participants could choose what sessions they wanted to attend and in the order they wished, so that they selected their own learning programme "à la carte". The 'Demonstration Fair' proved to be an excellent teaching tool as it provided students with plenty of opportunities to interact on a personal basis with tutors and to watch closely how to perform crystallisation experiments (Figure 6).

The theme of the last day was mineral growth, including lectures on crystallization 4,6 billions years ago, nanoscale observations of mineral growth and dissolution, crystal growth of nanocrystalline apatites, bio-controlled crystal growth of the mollusk Shell, from nanoparticles to crystals: or how does a mineral form (Figure 7). The School was closed with the presentation of prizes offered by the International Union of Crystallography, IACT, CSIC and the Crystallisation Factory.

Poster Sessions

The students made a great contribution to the success of the School presenting a total of 51 posters (Figure 8). Poster sessions rounded out each of the days and proved to be a very valuable time in order to discuss the scientific work. Student teams from Spain, Germany, Japan and Czech Republic were honoured by an international panel of lecturers, who decided to award 5 prizes for the best poster presentations (Table 1). These prizes consisted of two volumes of the International Tables of Crystallography offered by the IUCr, Bernhard Rupp's book titled Biomolecular Crystallography: Principles, Practice, and Application to Structural Biology and two DVDs produced by CNRS and ARN titled "Diving into the heart of the molecules of life" offered by the Crystallisation Factory.

Social events
In addition to the scientific course, there was a parallel social programme which consisted of a welcome cocktail on Sunday, a night tour of outstanding beauty to the Moorish palaces of The Alhambra on Wednesday (Figure 9) and a Flamenco dinner party on Thursday in the gypsy district of Sacromonte (Figure 10), which is worldwide renowned for its flamenco music.

Overall, the School was deemed to be very successful as judged by the majority of positive comments written in the evaluation form by the participants. The attendees were asked about three major items: the quality of the scientific programme, the demonstrations Fair, and the organisation (see Figure 11).

There was a general feeling among the participants that the School had been very valuable partly because of the quality of the programme and partly due to the contribution of some of the best lecturers for the wide range of topics covered.
All in all, the ISC2012 was an enriching experience for all of those involved triggering several fruitful scientific discussions. The positive approach, the openness and active participation of each of the participants made it a wonderful experience worthwhile to be repeated in the future.
Finally, we would like to express our gratitude to all of the participants; to the teachers for their full commitment and to the students and colleagues from academic and industrial background for believing in these Crystallisation Schools. We also wish to express our heartfelt thanks to the Members of the Organizing Committee for their substantial contributions to the Schools. We are very grateful to all the people who have worked very hard in preparing the Schools to make it successful. Last but not least, we would also like to express our gratitude to the Sponsors and Exhibitors for their great support.
