Journal ArticleDOI
Controlling ZIF-8 nano- and microcrystal formation and reactivity through zinc salt variations
Aleksandra Schejn,Lavinia Balan,Véronique Falk,Lionel Aranda,Ghouti Medjahdi,Raphaël Schneider +5 more
TL;DR: In this article, a simple method for controlling the crystal size and morphology of zeolitic imidazolate framework-8 (ZIF-8) nanocrystals in methanol solution was reported.
Journal ArticleDOI
Cu2+-doped zeolitic imidazolate frameworks (ZIF-8): efficient and stable catalysts for cycloadditions and condensation reactions
Aleksandra Schejn,Abdelhay Aboulaich,Lavinia Balan,Véronique Falk,Jacques Lalevée,Ghouti Medjahdi,Lionel Aranda,Kevin Mozet,Raphaël Schneider +8 more
TL;DR: In this paper, the backbones of open framework materials without losing their properties were incorporated with metal ions, and the body-centered cubic crystal lattice of the parent ZIF-8 framework was continuously maintained, regardless of the doping percentage.
Journal ArticleDOI
Fe3O4@ZIF-8: magnetically recoverable catalysts by loading Fe3O4 nanoparticles inside a zinc imidazolate framework.
Aleksandra Schejn,Thomas Mazet,Véronique Falk,Lavinia Balan,Lionel Aranda,Ghouti Medjahdi,Raphaël Schneider +6 more
TL;DR: A simple methodology for encapsulating ca.
Journal ArticleDOI
Size-controlled synthesis of ZnO quantum dots in microreactors.
Aleksandra Schejn,Mathieu Frégnaux,Jean-Marc Commenge,Lavinia Balan,Laurent Falk,Raphaël Schneider +5 more
TL;DR: Results obtained show that low reaction temperatures, high flow rates and the use of propionic acid as a stabilizing agent are favorable for the production of ZnO QDs with high photoluminescence quantum yields (up to 30%).
Journal ArticleDOI
Thermo-responsive and aqueous dispersible ZnO/PNIPAM core/shell nanoparticles
TL;DR: Results clearly evidence that both the PNIPAM layer thickness and the temperature affected the luminescence properties of the core/shell nanoparticles, but also that the P N-isopropylacrylamide layer, when it is thick enough, could stabilize the QDs' optical properties.
