The aza-Michael reaction as an alternative strategy to generate advanced silicon-based (macro)molecules and materials
TL;DR: Aza-Michael reaction can be improved by adding different co-reactants (polar protic solvents, catalysts) and/or adjusting the external energy sources (e.g. moderate to high temperatures or high pressures) as mentioned in this paper.

Toward replacement of styrene by bio-based methacrylates in unsaturated polyester resins
Sylvain Cousinet,Sylvain Cousinet,Ali Ghadban,Ali Ghadban,Etienne Fleury,Etienne Fleury,Frédéric Lortie,Frédéric Lortie,Jean-Pierre Pascault,Jean-Pierre Pascault,Daniel Portinha,Daniel Portinha +11 more
TL;DR: In this article, the compatibility of bio-based methacrylate derivatives with SMC/BMC processes has been studied in terms of volatility, miscibility with UPR and viscosity.

‘Pancake’ vs. brush-like regime of quaternizable polymer grafts: an efficient tool for nano-templating polyelectrolyte self-assembly
Pierre Laurent,Pierre Laurent,Pierre Laurent,Grégoire Souharce,Grégoire Souharce,Grégoire Souharce,Jannick Duchet-Rumeau,Jannick Duchet-Rumeau,Jannick Duchet-Rumeau,Daniel Portinha,Daniel Portinha,Daniel Portinha,Aurélia Charlot,Aurélia Charlot,Aurélia Charlot +14 more
TL;DR: In this paper, a tunable strategy based on the combination of Surface-Initiated Atom Transfer Radical Polymerization (SI-ATRP) and the Layer by Layer (LbL) deposition of polyelectrolytes, was exploited to design tailor-made poly electrolyte multilayers (PEM) with unusual nanometric features.

Nanomechanical and tribological characterization of the MPC phospholipid polymer photografted onto rough polyethylene implants
Na Wang,Ana-Maria Trunfio-Sfarghiu,Daniel Portinha,Sylvie Descartes,Etienne Fleury,Yves Berthier,Jean-Paul Rieu +6 more
TL;DR: Tribological measurements using a homemade biotribometer confirm that, despite heterogeneity thickness, the p(MPC) layer covers the roughness of the UHMWPE substrate and acts as an efficient lubricant with low friction coefficient and no wear for 9h of friction.
