Journal ArticleDOI
Enhanced esterification conversion in a room temperature ionic liquid by integrated water removal with pervaporation
TL;DR: In this paper, a catalyzed esterification reaction in the ionic liquid is studied, where one of the reaction products (water) is removed by pervaporation. But the results show that water removal from the reaction medium allowed shifting the reaction towards formation of the desired product.
Journal ArticleDOI
Rearrangement of Atrial Bundle Architecture and Consequent Changes in Anisotropy of Conduction Constitute the 3-Dimensional Substrate for Atrial Fibrillation
Bart Maesen,Stef Zeemering,Carlos A. M. Afonso,Jens Eckstein,Rebecca A.B. Burton,Arne van Hunnik,Daniel J. Stuckey,Damian J. Tyler,Jos G. Maessen,Vicente Grau,Sander Verheule,Peter Kohl,Ulrich Schotten +12 more
TL;DR: During AF, atrial bundle rearrangement manifests itself in more perpendicular orientation of epicardial to endocardial bundles, which underlies endo-epicardial dissociation of electrical activity and the development of a 3-dimensional AF substrate.
Journal ArticleDOI
Ionic liquids as a convenient new medium for the catalytic asymmetric dihydroxylation of olefins using a recoverable and reusable osmium/ligand.
TL;DR: The use of room-temperature ionic liquids in the Sharpless catalytic asymmetric dihydroxylation (AD) as a cosolvent or replacement of the tert-butanol was studied in detail by screening 11 different RTILs, providing a recoverable, reusable, robust, efficient, and simple system for the AD reaction.
Journal ArticleDOI

Fritz E. Kühn,Jin Zhao,Marta Abrantes,Marta Abrantes,Wei Sun,Carlos A. M. Afonso,Luís C. Branco,Luís C. Branco,Isabel S. Gonçalves,Martyn Pillinger,Carlos C. Romão +10 more
TL;DR: In this article, the performance of complexes of the type (η 5 -C 5 R 5 )Mo(CO) 3 X (X = Me, Cl; R = H, Me), being efficient homogeneous catalysts for the epoxidation of olefins, have been examined for their catalytic performance at 55°C in systems containing room temperature ionic liquids (RTILs).
Journal ArticleDOI
Glass transition relaxation and fragility in two room temperature ionic liquids
TL;DR: In this paper, the authors investigated the features of the glass transition relaxation of two room temperature ionic liquids using DSC and concluded that these kind of materials belong to the class of relatively strong glass-forming systems.
