Laboratory 6.2 “Disperse systems and rheology in clean technologies” within WP 6 “Nano-structured materials and disperse systems in clean technologies” aims at the development of new systems for clean technologies and nanotechnologies in various scientific and technological areas: new cleaning agents for hard surfaces; encapsulation and controlled release of reagents; wetting and dewetting processes. The main objectives are to conduct experimental and theoretical research and development of new dispersed systems through the inclusion of new raw materials and innovative materials, and to develop and apply theoretical models of the interactions and stability of complex dispersed systems. High scientific output of Lab 6.2 is manifested via 21 scientific publications in the fields of Dispersion Chemistry, Chemical and Materials Sciences for the period 2018 – 2024 (8 articles in Q1 journals, 6 in Q2, and 7 materials in Q4). Optimized compositions of cleaning formulations for hard surfaces with sulfonated methyl esters have been obtained [1]. New theoretical models for the interactions that determine the structures in micellar systems have been developed and applied [2]. New phenomena such as vortexing [3] and nanoemulsification [4] have been described. New methods have been proposed for obtaining emulsions and foams from triglyceride phases [5]. The role of the components and compositions for the rheology [6], wetting, and cleaning [7] has been demonstrated.
