Dual Valorization of Lignin as a Versatile and Renewable Matrix for Enzyme Immobilization and (Flow) Bioprocess Engineering

Jeremy Luterbacher, Jean Thierry C Behaghel de Bueren, Stefania Bertella

Lignin has emerged as an attractive alternative in the search for more eco-friendly and less costly materials for enzyme immobilization. In this work, the terephthalic aldehyde-stabilization of lignin is carried out during its extraction to develop a serie ...

New Approach to Synthesis of Tetralin via Naphthalene Hydrogenation in Supercritical Conditions Using Polymer-Stabilized Pt Nanoparticles

Lioubov Kiwi

Supercritical (SC) fluid technologies are well-established methods in modern green chemical synthesis. Using SC fluids as solvents instead of traditional liquids gives benefits of higher diffusivity and lower viscosity, which allows mass transfer intensifi ...

Mechanical energy budget and mixing efficiency for a radiatively heated ice-covered waterbody

Alfred Johny Wüest, Damien Bouffard, Hugo Nicolás Ulloa Sánchez

Ice-covered waterbodies are far from being quiescent systems. In this paper, we investigate ice-covered freshwater basins heated by solar radiation that penetrates across waters with temperatures below or near the temperature of maximum density. In this sc ...

Chemoselective three-phase hydrogenation of an Ombrabulin nitro-stilbene intermediate in a continuous-flow mobile platform

Lioubov Kiwi, Charline Berguerand

The chemoselective three-phase hydrogenation of an Ombrabulinintermediate based on a nitro-stilbene framework was used as a case study for the formation of the primary amine without affecting the double bond. Two catalysts were tested: Pt nanoparticles sup ...

Plasma deposition in an ideal showerhead reactor: a two-dimensional analytical solution

Christoph Hollenstein, Alan Howling, Boris Legradic, Michaël Chesaux

The interplay of gas flow and depletion by plasma dissociation determines the spatial distribution of species and the deposition uniformity in a plasma source. Many plasma reactors use a gas showerhead and the design of the flow dynamics is a critical aspe ...

Algebraic turbulence modeling in adiabatic and evaporating annular two-phase flow

John Richard Thome, Andrea Cioncolini

The study considers algebraic turbulence modeling in adiabatic and evaporating annular two-phase flow, focusing in particular on momentum and heat transfer (so-called 'convective boiling') through the annular liquid film. In contrast with single-phase wall ...
