Luminescent Lanthanide Helicates Self-Assembled from Ditopic Ligands Bearing Phosphonic Acid or Phosphoester Units

Jean-Claude Bünzli, Anne-Sophie Chauvin, Steve Comby, Cyntia De Piano, Céline Rita Duhot, Matthias Baud

A series of hexadentate ditopic receptors incorporating benzimidazole moieties have been designed, which are fitted with phosphonic acid or phosphoethylester coordinating units. In addition, poly(oxyethylene) pendants have been introduced on the benzimidaz ...

Computational Framework for Predictive Biodegradation

Vassily Hatzimanikatis, Stacey Deleria Finley

As increasing amounts of anthropogenic chemicals are released into the environment, it is vital to human health and the preservation of ecosystems to evaluate the fate of these chemicals in the environment. It is useful to predict whether a particular comp ...

Three-dimensional extracellular matrix-directed cardioprogenitor differentiation: Systematic modulation of a synthetic cell-responsive PEG-hydrogel

Matthias Lütolf, Jeffrey Alan Hubbell

We show that synthetic three-dimensional (3D) matrix metalloproteinase (MMP)-sensitive poly(ethylene glycol) (PEG)-based hydrogels can direct differentiation of pluripotent cardioprogenitors, using P19 embryonal carcinoma (EC) cells as a model, along a car ...

Biphasic Electrospray Ionization for the Study of Interfacial Complexes

Hubert Girault, Manuel Alejandro Méndez Agudelo, Michel Prudent

Biphasic electrospray ionization (BESI) mass spectrometry is achieved by using a dual-channel microsprayer, where channels filled with different immiscible phases meet at the Taylor cone. Two types of interfacial complexation reactions have been studied: t ...

Suzuki Coupling Reactions in Ether-Functionalized Ionic Liquids: The Importance of Weakly Interacting Cations

Paul Joseph Dyson, Zhaofu Fei, Christian Hartinger, Andrew Douglas Phillips, Yuehui Li, Xuemei Yang

Imidazolium- and pyridinium-based ionic liqs. with ether/polyether substituents have been evaluated as solvents for palladium-catalyzed Suzuki C-C coupling reactions. In general, reactions proceed more efficiently in these solvents compared to other ionic ...

A Versatile Ditopic Ligand System for Sensitizing the Luminescence of Bimetallic Lanthanide Bio-Imaging Probes

Jean-Claude Bünzli, Anne-Sophie Chauvin, Caroline Vandevyver, Bo Song, Steve Comby

The homoditopic ligand 6,6’- [methylenebis(1-methyl-1H-benzimid- azole-5,2-diyl)]bis(4-{2-[2-(2-methoxy- ethoxy)ethoxy]ethoxy}pyridine-2-carboxylic acid) (H2LC2) has been tailored to self-assemble with lanthanide ions (LnIII), which results in the formatio ...

Influence of sediment settling velocity on mechanistic soil erosion modeling

David Andrew Barry, Marc Parlange

We report on a series of soil erosion experiments performed on the 2-m x 6-m EPFL erosion flume. Total sediment concentrations and the concentrations of seven size fractions (1000 mm) were measured during 1 ...
