Design and function of novel superplasticizers for more durable high performance concrete (superplast project)

In this article we shall describe our quest and ultimate success in furthering our understanding of the action of superplasticizers on the rheology of cement and concrete. By specifically producing superplasticizers with varied architectures, we…

Formation process of shear-induced onion structure made of quaternary system SDS/octanol/water/NaCl

The formation process of onion structure in a quaternary mixture made of water, NaCl, octanol and sodium dodecyl sulphate, have been investigated by two dimensional light scattering under various shear rates. In this Letter, we investigated the size…

Excitation transfer in functionalized carbon nanotubes

Tailoring properties of carbon nanotubes properties by functionalizing their side-wall is one of the key challenges towards the realization of carbon nanotube-based optoelectronic devices [1, 2]. This technique aims at combining the great transport…

Multicolor Emission of Small Molecule-Based Amorphous Thin Films and Nanoparticles with a Single Excitation Wavelength

Fluorescent organic nanoparticles (FON) made of small molecules recently arouse considerable interest in biomedical imaging and opto-electronics as potential microlasers or emitting displays.2 Their collective emission largely enhanced with respect…

Ruthenium(II) Complexes for Two-Photon Absorption-Based Optical Power Limiting

Long-lived excitation: Novel bifluorene-substituted 1,10-phenanthroline-based RuII coordination complexes are presented (see picture). They fulfil several requirements for optimized optical power limiting in the visible-NIR, as they are stable,…

Scanning-less wide-field single-photon counting device for fluorescence intensity, lifetime and time-resolved anisotropy imaging microscopy

A scanning-less single-photon counting system for FLIM and fluorescence anisotropy wide-field imaging is described and characterized in this paper. The two polarizations of the fluorescence are divided by a Glan prism and acquired at the same time…
