New Polymers from Biomass-Derived Hydroxycinnamic Acid Derivatives
Polymers play a central role in shaping our world across various fields, but their heavy reliance on petrochemicals poses climate change, environmental and health risks. To address and alleviate these issues, transitioning to sustainable polymers, sourced ...
EPFL2024CO2 Capture and Release in Amine Solutions: To What Extent Can Molecular Simulations Help Understand the Trends?
Wanda Andreoni, Fabio Pietrucci, Changru Ma
Absorption in amine solutions is a well-established advanced technology for CO2 capture. However, the fundamental aspects of the chemical reactions occurring in solution still appear to be unclear. Our previous investigation of aqueous monoethanolamine (ME ...
MDPI2023Mechanical reinforcement and memory effect of strain-induced soft segment crystals in thermoplastic polyurethane-urea elastomers
Nicolas Candau, Oguzhan Oguz, Adrien Julien Demongeot
An amorphous poly(urethane-urea) copolymer composed of 70 wt% poly(ethylene oxide) (PEO) soft segments (SS) (Mw = 2000 g mol−1) and 30 wt% cycloaliphatic hard segments (HS) was subjected to in-situ X-Rays during tensile deformation. Mechanical hardening at ...
2021Multifunctional hybrid alginate-based hydrogels for cell immobilization
Cell therapy could be a solution for many diseases that currently pose a huge health burden on patients. Especially, cell therapies based on cell microencapsulation are of great interest. Immunoprotection of cells would allow to avoid the need for immunosu ...
EPFL2020Pivotal Role of the Basic Character of Organic and Salt Catalysts in C-N Bond Forming Reactions of Amines with CO2
Paul Joseph Dyson, Martin Hulla
Organocatalysts promote a range of C-N bond forming reactions of amines with CO2. Herein, we review these reactions and attempt to identify the unifying features of the catalysts that allows them to promote a multitude of seemingly unrelated reactions. Ana ...
2019Organocatalysts in C-N Bond Forming Reactions of Amines with CO2
The thesis describes a simple approach for N-formylation of amines with CO2 and hydrosilane reducing agents, the use of organic salts as N-formylation catalysts, their physical properties required for high catalytic activity and their role in the catalytic ...
EPFL2019En route to CO2-containing renewable materials: catalytic synthesis of polycarbonates and non-isocyanate polyhydroxyurethanes derived from cyclic carbonates
Paul Joseph Dyson, Felix Daniel Bobbink, Antoine Philippe Van Muyden
Combining CO2-chemistry with biomass conversion allows renewable polymeric materials including polycarbonates and polyhydroxyurethanes (PHUs) to be generated. The demand for robust materials with modular properties that can be prepared on an industrial sca ...
