Microalgal carotenoid recovery in a biorefinery approach

Christof Holliger, Christian Ludwig, Jean-Paul Schwitzguebel, Mariluz Bagnoud, Olivier Laurent Emery

Introduction Microalgae culture to be effective as feedstock for bio-energy production needs to overcome constraining biotechnological, technological and economic factors [1]. In order to establish an economically viable process, the co-production of renew ...

Minimal State Representation for Open Fluid-Fluid Reaction Systems

Dominique Bonvin, Philippe Müllhaupt, Michael Amrhein, Nirav Pravinbhai Bhatt

Reaction systems are typically represented by first-principles models that describe the evolution of the states (typically concentrations, volume and temperature) by means of conservation equations of differential nature and constitutive equations of algeb ...

Three-dimensional phase-field simulation of micropore formation during solidification: Morphological analysis and pinching effect

Michel Rappaz, Alain Jacot, Jean-Luc Desbiolles, Hossein Meidani

A three-dimensional (3-D) multiphase-field model has been developed in order to study the formation of a micropore constrained to grow in a solid network (i.e. pinching effect). The model accounts for the pressure difference due to capillarity between liqu ...

Interfacial Self-Assembly of Water-Soluble Cationic Porphyrins for the Reduction of Oxygen to Water

Hubert Girault, Astrid Johana Olaya Avendano, Pierre-François Marie Brevet

Meet at the border: Assembly of the water-soluble cobalt tetrakis(N-methylpyridinium-4-yl)porphyrin [CoTMPyP]4+ at soft interfaces is enhanced and stabilized by its interfacial interaction with the lipophilic anion (C6F5)4B−. The supramolecular structure t ...

Au/Mo2N as a new catalyst formulation for the hydrogenation of p-chloronitrobenzene in both liquid and gas phases

Lioubov Kiwi, Fernando Cardenas Lizana, Daniel André Samuel Lamey

The batch liquid phase hydrogenation of p-chloronitrobenzene over MO2N resulted in the sole formation of p-chloroaniline. Incorporation of Au nanoparticles (mean size = 8 nm) enhanced hydrogen uptake with a fourfold increase in rate, retention of ultrasele ...

Immunosuppressive Activity of Size-Controlled PEG-PLGA Nanoparticles Containing Encapsulated Cyclosporine A

Li Tang

We encapsulated cyclosporine A (CsA) in poly(ethylene glycol)-b-poly(d,l-lactide-co-glycolide) (PEG-PLGA) nanoparticles (NPs) by nanoprecipitation of CsA and PEG-PLGA. The resulting CsA/PEG-PLGA-NPs were
