The potential of wood fibers as reinforcement in cellular biopolymers

Jan-Anders Edvin Maansson, Pierre-Etienne Bourban, Matthieu Cuénoud, Razvan Cristian Neagu

Wood fiber-reinforced polylactic acid composite foams have been successfully produced using supercritical carbon dioxide. The addition of fibers had a strong effect on microstructure of the foams. An increase in wood fiber content implied smaller average c ...

Interfacial Photoreduction of Supercritical CO2 by an Aqueous Catalyst

Hubert Girault, Manuel Alejandro Méndez Agudelo, Patrick Voyame

Not just a solvent anymore: CO2 reduction under supercritical conditions was achieved in a biphasic water–supercritical CO2 system using an aqueous soluble catalyst (see picture). The introduction of such an interface provides a suitable reaction medium wh ...

Optimal process design for the polygeneration of SNG, power and heat by hydrothermal gasification of waste biomass: Process optimisation for selected substrates

François Maréchal, Frédéric Vogel, Martin Gassner

Based on a previously developed thermo-economic process model, this paper presents a detailed design study for the polygeneration of Synthetic Natural Gas (SNG), power and heat by catalytic hydrothermal gasification of biomass and biomass wastes in supercr ...

Interactions and Reactivity at Liquid-Liquid Interfaces : A Bio-Inspired System

Manuel Alejandro Méndez Agudelo

The interface between two immiscible electrolyte solutions (ITIES) provides a well-defined platform for fundamental studies of adsorption processes and molecular reactivity in general. Two bio-inspired systems are considered in the present work: adsorbed p ...

The important role of pressure in supercritical fluid process development revealed by reaction calorimetry

Thierry Meyer

The technique of reaction calorimetry adapted for use with reactions in supercritical fluids was used to study some safety aspects of the free-radical dispersion polymerization of methyl methacrylate in scCO2. The reaction heat rate profile was found to ch ...
