Three AURIGA doctoral students — Alberto Arici, Vitor Regert and Djamel Eddine Aissaoui — presented their work at CHISA 2026, the 28th International Congress of Chemical and Process Engineering, held in Prague from 23 to 28 August 2026. Djamel Eddine Aissaoui’s contribution to the congress poster competition won the best poster award.
Best poster award
Entered in the congress poster competition, Influence of bubble release mechanism on the rise velocity and deformation of single bubbles in aqueous ionic liquid solutions was awarded the best poster prize. The work is by Djamel Eddine Aissaoui, Andrea Ferrario, Nicolò Varallo, Hendrik Hessenkemper and Giorgio Besagni, and continues the single-bubble line of the bubble-scale work package in collaboration with the Helmholtz-Zentrum Dresden-Rossendorf.
