Characterization of water sorption cycle in the cement microstructure of controlled oxide composition
This thesis investigates the water vapour sorption behaviour of samples with maximized calcium-silicate-hydrate (C-S-H) content. Primarily, the role of heterogeneous and homogeneous cavitation has been studied during the drying of cementitious materials. C ...
EPFL2022A smart low molecular weight gelator for the triple detection of copper (II), mercury (II), and cyanide ions in water resources
Novel supramolecular gelators based on quinoline-indolin-2-one structure were synthesized. These gelators formed stable organogels in a mixture of DMSO/H2O (1:1). The scanning electron microscopy (SEM), IR and NMR spectroscopies, and rheological measuremen ...
ELSEVIER2020Influence of curing temperature on cement paste microstructure measured by H-1 NMR relaxometry
Karen Scrivener, Arnaud Charles Albert Muller
H-1 nuclear magnetic resonance (NMR) relaxometry, supported by X-Ray diffraction and thermogravimetric analysis, has been used to characterise microstructure of white cement pastes underwater cured at temperatures in the range 10 degrees C to 60 degrees C. ...
PERGAMON-ELSEVIER SCIENCE LTD2019Water Redistribution-Microdiffusion in Cement Paste under Mechanical Loading Evidenced by H-1 NMR
The mobility of water within the microstructure of hardened cement paste has been at the center of a long-lasting debate, motivated by the need to understand the fundamental mechanisms that play a role in drying, shrinkage, creep, and thermal expansion. Ou ...
AMER CHEMICAL SOC2019Equilibrium and Out-of-Equilibrium Adherence of Hydrogels against Polymer Brushes
Jennifer Mary Adrienne Alice Macron, Costantino Creton
At low pH, underwater adherence between poly(N,N-dimethylacrylamide) hydrogels and poly(acrylic acid) brushes is due to the formation of multiple hydrogen bonds. The effect of the key parameters controlling the formation of these interactions (contact time ...
AMER CHEMICAL SOC2018A reassessment of mercury intrusion porosimetry by comparison with H-1 NMR relaxometry
Karen Scrivener, Arnaud Charles Albert Muller
This paper shows how MIP measurements can give an accurate picture of the capillary porosity of cement pastes. Regions of the intrusion curves can be identified corresponding to capillary or gel pores. The amount of capillary pores is in excellent agreemen ...
Elsevier2017Assessment Of The Dispersion Quality Of Refractive Index-Matched Nanodispersions
Dispersion quality has a large influence on the resulting properties of filled polymers, hybrids and nanocomposites in general. Reducing the van der Waals forces and therefore, matching the refractive index between the filler and the matrix should improve ...

Paul Muralt, Thomas Maeder, Bo Jiang, Shuangyi Zhao, Matthias M. Koebel, Eunho Jeong, Nayoung Kim
With growing public interest in portable electronics such as micro fuel cells, micro gas total analysis systems, and portable medical devices, the need for miniaturized air pumps with minimal electrical power consumption is on the rise. Thus, the developme ...
Amer Chemical Soc2015A four-component organogel based on orthogonal chemical interactions
Kay Severin, Kurt Schenk, Nicolas Luisier
A thermoresponsive organogel was obtained by orthogonal assembly of four compounds using dynamic covalent boronate ester and imine bonds, as well as dative boron-nitrogen bonds. It is shown that the gel state can be disrupted or reinforced by chemicals whi ...
Royal Society of Chemistry2014New analytical tools combining gel electrophoresis and mass spectrometry
Proteomics has been one of the main projects challenging biological and analytical chemists for many years. The separation, identification and quantification of all the proteins expressed within biological systems remain the main objectives of proteomics. ...
