Development and evaluation of methods to follow microstructural development of cementitious systems including slags

Production of cementitious materials causes the emission of CO2 gas, which has detrimental impact on the environment augmenting the global warming process. Using by-products such as slags is a possible strategy to limit the environmental impact of cementit ...

Relationship Between Structure and Solubility of Thiol-Protected Silver Nanoparticles and Assemblies

Francesco Stellacci

The solubility of alkylthiol-coated silver nanoparticles and the energetics of the ligand disordering have been investigated. Calorimetry measurements have provided correlations between the nature of the ligands and the enthalpy of the ligand disordering, ...

Modeling of thermal responses for FRP composites under elevated and high temperatures

Thomas Keller, Yu Bai, Till Vallée

Based on temperature-dependent thermo-physical property models developed previously, a one-dimensional model was proposed to predict the thermal responses of FRP composites in time and space domain, up to high temperatures. An implicit finite differential ...

Rational Tuning of Melting Entropies for Designing Luminescent Lanthanide-Containing Thermotropic Liquid Crystals at Room Temperature

Jean-Claude Bünzli, Frédéric Gumy, Annina Aebischer

The connection of twelve peripheral and divergent dodecyloxy chains to a central tridentate aromatic binding unit provides the dodecacatenar ligand L11, for which room- temperature mesomorphism is detected. An enthalpically unbalanced large melting entropy ...
