A 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 ...

New analytical tools combining gel electrophoresis and mass spectrometry

Elena Tobolkina

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. ...

Densification of C-S-H Measured by H-1 NMR Relaxometry

Karen Scrivener, Arnaud Charles Albert Muller

The nanoscale morphology of, and pore water interactions in, calcium silicate hydrate (C-S-H), the active component of cement, remain uncertain. H-1 nuclear magnetic resonance (NMR) can fully characterize the nanoporosity of C-S-H in as-prepared material w ...

Coupling Isoelectric Focusing Gel Electrophoresis to Mass Spectrometry by Electrostatic Spray Ionisation

Hubert Girault, Liang Qiao, Elena Tobolkina

Gel electrophoresis has been used for decades as a high-resolution separation technique for proteins and protein isomers, but limited in the coupling with MS because of low throughput and poor automaticity compared with LC-MS. In this work, we have develop ...

Investigation of the role of anions in hydrotalcite for quasi-solid state dye-sensitized solar cells application

Michael Graetzel, Xiaoyan Wang

In recent research in clean energy applications, clay has gained significant interest, especially as a gelator in dye-sensitized solar cells (DSSCs), for its capability to resolve the leakage issue of liquid electrolyte. In this paper, anionic hydrotalcite ...

Superhard transparent hybrid nanocomposites for high fidelity UV-nanoimprint lithography

Yves Leterrier, Maïté Blank, Marina Aymara González Lazo

Transparent hyperbranched acrylate nanocomposites were produced using different combinations of silica nanoparticles and silicon-based sol-gel precursors. The nanocomposites were processed using a dual-cure UV polymerization and condensation scheme. The vi ...

A silica sol-gel design strategy for nanostructured metallic materials

Michael Graetzel, Scott Charles Warren

Batteries, fuel cells and solar cells, among many other high-current-density devices, could benefit from the precise meso-to macroscopic structure control afforded by the silica sol-gel process. The porous materials made by silica sol-gel chemistry are typ ...
