Cellulose Acetate Modification Towards Antibiofilm Properties via Chemical Attachment of Quaternary Ammonium Compounds using Supercritical CO2
(13th International Symposium on Supercritical Fluids Montreal, ISSF2022, Canada, May 15-18, 2022, 2022)
There is an urgency to develop novel materials capable of preventing the adherence of microorganisms to
their surface. Such materials with antibiofilm properties are needed in hospitals and public places, animal
farms ...
The influence of thermodynamic parameters on alkaline activators of geopolymers and the structure of geopolymers
(Macedonian Journal of Chemistry and Chemical Engineering, 2021)
Thermodynamic parameters (densities, viscosities, speed of sound, and refractive index) of four series of alkaline activators were determined over the temperature range from 15 to 60 degrees C for the process of ...
Application of Supercritical Solvent Impregnation for Production of Zeolite Modified Starch-Chitosan Polymers with Antibacterial Properties
(MDPI, Basel, 2020)
In the present study, supercritical solvent impregnation (SSI) has been applied to incorporate thymol into bio-composite polymers as a potential active packaging material. Thymol, a natural component with a proven antimicrobial ...
Supercritical CO2 Impregnation of Thymol in Thermoplastic Starch-Based Blends: Chemico-Physical Properties and Release Kinetics
(MDPI, 2022)
The aim of the present study was to investigate starch-based materials, prepared in an environmentally friendly way and from renewable resources, suitable for the development of biodegradable active food packaging. For ...
The integrated process of supercritical CO2 extraction from Helichrysum italicum and supercritical impregnation of biocompatible polymers with the obtained extract
(18th European Meeting of Supercritical fluids (EMSF), 3-6 May 2021, Bordeaux, France, 2021)
The coupling of supercritical fluid extraction and supercritical solvent impregnation processes has been proved to be convenient in cases where the active substance, to be incorporated in the solid carrier, is supercritical ...
