The 21^st International Symposium on Solubility Phenomena and Related Equilibrium Processes (ISSP21) took place from 9-13 September 2024, in Novi Sad, Serbia. In the year when ISSP celebrates its 40^th birthday since the first symposium in London, Ontario Canada in 1984, and 50 years of the Solubility data project, whose first meeting happened in Montreal, Canada in 1974, the conference was organized by the University of Novi Sad and chaired by Slobodan Gadžurić (University of Novi Sad, Serbia). The ISSP21 is a continuation of the successful IUPAC conference series, which brings together new results of our scientific work and presents and discusses new findings on various scientific and technological issues related to solubility phenomena and chemical equilibria.

The conference covered various scientific topics, including:

Aqueous Solutions
Biofuels
Computer Assisted Equilibrium Calculation
Deep Eutectic Solvents
Environmental Equilibrium Processes and Applications
Fluid Phase Equilibria
Molten Salts
Ionic Liquids
Nuclear Wastes
Solution Chemistry Complex Equilibria
Solubility Phenomena in Pharmaceutical applications

The conference was attended by more than 60 registered participants from 17 countries worldwide. The invited speakers delivered 5 plenary and 8 keynote talks.

Plenary lectures

Ivo Leito, University of Tartu, Estonia – Using the available pK_a data in non-aqueous solvents
Clara Magalhães, University of New South Wales, Australia – Chemistry in Art and Art in Chemistry
Andrea Mele, Politecnico di Milano, Italy – Thirty years of Ionic Liquids
Mirjana Minčeva, Technical University of Munich, Germany – Exploring the Potential: Design Strategies and Applications of Deep Eutectic Solvents
Zdenek Wagner, Czech Academy of Science, Czechia – Calorimetric and phase equilibrium data: from design of measurements methods to assessment of uncertainty and critical evaluation

Keynote lectures

Magdalena Bendová, University of Chemistry and Technology, Czechia – Solution behaviour of chiral organic chlorides in water and wet octanol
Blanka Kubiková, Slovak Academy of Sciences, Slovakia – Study of solubility of oxides in molten salts
Miha Lukšič, University of Ljubljana, Slovenia – The Intricate Role of Salts and Sugars in Biomolecular Complexation
Demetrio Milea, Università degli Studi di Messina, Italy – Modeling the dependence of stability constants on medium and ionic strength. The pure water model
Caroline Da Ros Montes d’Oca, Federal University of Paraná, Brasil – Ionic Liquids in organic synthesis: mechanistic aspects in Knoevenagel reactions
Ricardo Simões, Universidade de Lisboa, Portugal – Solute Aggregates in Solution and the Crystallization of Organic Molecules
Tatjana Trtić-Petrović, University of Belgrade, Serbia – Insight into the impact of ionic liquids on forming aqueous biphasic systems
Tatjana Verbić, University of Belgrade, Serbia – Drug solubility enhancement: from buffer complexes formation to acid-base supersolubilization

The program was compiled from 34 oral presentations. In addition, 25 posters were presented. The Book of Abstracts comprising all contributions is available on the conference web page.

All oral and poster presentations of the early-stage researchers were evaluated by five poster evaluators (Clara Magalhães, Wolfgang Voigt, Demetrio Milea, Earl Waghorne, and Glenn Hefter), and the best oral and the best poster presenters were awarded during the conference dinner a book voucher of 250 euros sponsored by SPRINGER. The awarded students are:

Bence Kutus, University of Szeged, Hungary for the best oral presentation, and
Dajana Lazarević, Vinča Institute of Nuclear Sciences, Belgrade, Serbia for the best poster presentation.

In addition, two Franzosini prizes were presented to:

Cezary Gumiński from the University of Warsaw, Poland, and
Christian Ekberg from the University of Göteborg in Sweden,

for their work dedicated to solubility phenomena and critical evaluation of the equilibrium data.

The workshop on Assessment of Reliability and Uncertainty of Solubility Data on the 9th September afternoon.

For the first time, the newly established Balarew Award was given to promising young scientist working in the field of solubility and related equilibrium processes. The first awardee was presented to:

Märt Lõkov from the University of Tartu, Estonia.

During this conference, Clara Magalhães, the IUPAC representative at ISSP21, gave a presentation on the various activities of IUPAC.

A half-day Workshop on Assessment of Reliability and Uncertainty of Solubility Data sponsored by IUPAC was also organized in a hybrid model. The speakers were:

Zdeněk Wagner, Institute of Chemical Process Fundamentals of the Czech Academy of Sciences, Czechia – Assessment of repeatability and reproducibility and robust regression of non-normally distributed data
Earle Waghorne, University College Dublin, Ireland – Calculation of consensus values
Ala Bazyleva and Vladimir Diky, National Institute of Standards and Technology, USA – Reliability of thermodynamic property data
Johan Jacquemin, Mohammed VI Polytechnic University, Morrocco Thermodynamic data mining and data curation

On Sunday, 8 September 2024, the Annual meeting of the IUPAC Subcommittee on Solubility and Equilibrium Data (SSED) was held at the Faculty of Science, University of Novi Sad from 9am to 6pm in a hybrid form.

In addition to the busy scientific program, the conference was also rich in social events. The conference city tour and wine tasting took place on Wednesday, September 11, 2024, in the afternoon. The conference banquet took place on Thursday, September 12, in the evening in the national restaurant Aqua Doria, which offers traditional Serbian cuisine.

Springer offers the possibility to publish articles from the conference in a special issue of the Journal of Solution Chemistry after a peer-review process. Plenary and keynote speakers have been invited to publish their papers in a special issue of Pure and Applied Chemistry.
