Generation of silicone poly-HIPES with controlled pore sizes via reactive emulsion stabilization

open access: yes, 2016
Macrocellular silicone polymers are obtained after solidification of the continuous phase of a PDMS (polydimethylsiloxane) emulsion, which contains PEG (polyethylene glycol) drops of sub-millimetric dimensions. Coalescence of the liquid template emulsion

Supramolecular Design of Polymeric Random Lasers

open access: yesAdvanced Optical Materials, Volume 13, Issue 20, July 11, 2025.
This research investigates the application of PolyHIPE scaffolds as scattering media inRLs. By modifying the scaffold's morphology, pore size, and surface chemistry, the dye distribution within the material is precisely controlled, achieving a tunable laser threshold.

Experimental and Modeling of Sulfonation of Styrene‐Based Resins Crosslinked With DVB and TMPTA

open access: yesChemical Engineering &Technology, Volume 48, Issue 6, June 2025.
This study explores how reaction conditions influence the performance of sulfonated styrene resins cross‐linked with DVB and TMPTA. Results show that tuning parameters like temperature and solvent swelling significantly enhances sulfonic group incorporation, especially in TMPTA‐based resins. Modeling reveals key structural differences and insights into
