Research topic
We investigate the use of supercritical fluids in different processes:
1) Deposition of metal nanoparticles within porous supports using supercritical CO2 for catalytic and biomedical applications. [Sánchez-Miguel et al., Green preparation of PtRu and PtCu/SBA-15 catalysts using supercritical CO2, J CO2 Utilization 22, 382–391 (2017)]
2) Surface modification of materials for CO2 capture and metal absorption. [Sanchez-Vicente et al., A new sustainable route in supercritical CO2 to functionalize silica SBA-15 with 3-aminopropyltrimethoxysilane as material for carbon capture, Chem. Eng. J. 2015, 264, 886-898; M.J. Tenorio et al., Thiol group functionalization of mesoporous SiO2 SBA-15 using supercritical CO2, Microporous and Mesoporous Materials, 256,147-154 (2018)]
3) Micronization of pharmaceutical and nutraceuticals and composite materials by the Supercritical Antisolvent Technique (SAS).[Cuadra et al., Pharmaceutical co-crystals of the anti-inflammatory drug diflunisal and nicotinamide obtained using supercritical CO2 as an antisolvent. J. CO2 Utilization 2016, 13, 29-37.]
4) Encapsulation of pharmaceutical and nutraceuticals by Supercritical Fluid Extraction of Emulsions (SFEE).[Prieto and Calvo, Supercritical fluid extraction of emulsions to nanoencapsulate vitamin E in polycaprolactone, Journal of Supercritical Fluids 119 (2017) 274-282]
5) Sterilization of sensitive materials using Supercritical Fluids. [Calvo and Casas, Method for sterilization with CO2 and water, ES 2533537 A1, 2014.]
6) Thermodynamic properties of mixtures with supercritical fluids: a) Experimental determination of the phase behavior, solubilities and calorimetric properties and b) Modeling of the data with equations of state and semiempirical methods.[Morere et al, Solubility of two meta
