Diformylxylose as a new polar aprotic solvent produced from renewable biomass

Jeremy Luterbacher, Anastasiia Komarova, Graham Reid Dick

Lignin is a promising candidate for the replacement of fossil-based materials, due to its natural abundance and aromatic structure. This same structure poses major challenges to lignin's exploitation for material development. The harsh conditions generally ...

Influence of Ablation on Vacuum-Ultraviolet Radiation in a Plasma Wind Tunnel Flow

Pénélope Leyland

Plasma wind tunnel experiments have been performed simulating a Hayabusa reentry trajectory point at 78.8km altitude with a velocity of 11.7km/s corresponding to a local mass-specific enthalpy of 68.4MJ/kg and a stagnation pressure of 2.44kPa. Ablation-rad ...

Solvent-Enabled Nonenyzmatic Sugar Production from Biomass for Chemical and Biological Upgrading

Jeremy Luterbacher, Ydna Marie Questell-Santiago, Jher Hau Yeap

We recently reported a nonenzymatic biomass deconstruction process for producing carbohydrates using homogeneous mixtures of γ-valerolactone (GVL) and water as a solvent. A key step in this process is the separation of the GVL from the aqueous phase, enabl ...

Characterization of solvent-filled polyurethane/urea-formaldehyde core-shell composites

Véronique Michaud, Sam Neuser, Erica Manfredi

Encapsulation of liquid phases is a crucial step in many self-healing material systems where a healing agent has to be protected during processing and then released during a damage event. In this work, the mechanical properties of polyurethane (PU) reinfor ...

Optimisation of low pressure processing for honeycomb sandwich structures

Sandra Sequeira Lopes Tavares

Vacuum-bag processing of honeycomb sandwich structures faces particular challenges compared to autoclave sandwich fabrication for aeronautics, a consequence of using, at the most, atmospheric pressure for their manufacturing. In particular, the adhesion of ...
