One of the most important environmental concerns for the polymer industry is to produce new products with near-zero residual monomer content. A new process based on supercritical CO2 has been successfully tested for the extraction of the residual monomer and the simultaneous micronization of the polymer. The process has been tested on a pilot-scale plant.(More)
Supercritical antisolvent micronization (SAS) is a versatile technique that allows the obtainment of different morphologies and dimensions of precipitates, but only in some cases nanoparticles were produced. This work is focused on the selection of the SAS operating conditions to obtain this morphology. A series of experiments on several compounds and(More)
This paper assesses the feasibility of producing a metallurgical quality charcoal (biocoke) through slow high temperature pyrolysis of woody biomass. The samples used for the experiments were different types of olive wood biomass from southern Spain as well as eucalyptus trunks from Uruguay. The experiments were conducted in a two-step process: a pyrolysis(More)
Aerogels are a special class of nanoporous materials with increasing interest in biomedical and pharmaceutical applications due to their open pore structure and high surface area. Among them, polysaccharide aerogels are biodegradable and biocompatible and, therefore, can be used as carriers for drug delivery systems. In this work, an analysis of their(More)
Tissue engineering (TE) is an emerging field aimed at repairing defective tissues and organ, instead of relying on conventional organ transplantation. Among the polymeric materials proposed for TE applications, the water-soluble polymers have been frequently used in form of hydrogels, that are a class of highly hydrated polymer materials. Nevertheless,(More)
