A facile method for the fabrication of dendritic gold nanoparticles (NPs) by use of an ionic polymer template has been developed. In situ generation of an imidazolium-based (cationic) polymer, poly[1-methyl-3-(4-vinylbenzyl)imidazolium], with AuCl4- counte ...
Recently, the possibility of generating nonclassical polariton states by means of parametric scattering has been demonstrated. Excitonic polaritons propagate in a complex interacting environment and contain real electronic excitations subject to scattering ...
The fluorescent imidazolium salt (1,3-bis(9-anthracenylmethyl)imidazolium chloride, [bamim]Cl) has been grafted onto the surfaces of single-walled carbon nanotubes (SWNTs) using an ion exchange strategy based on metathesis of the K+ ion in CO2K derivatized ...
We report on a microscopic investigation of the polariton parametric emission in the presence of coherent and incoherent interaction processes by means of a full quantum description based on a nonequilibrium quantum Langevin approach for open systems appli ...

We have synthesized Si Nps rich submicron area within a thin SiO2 layer using a new method called “stencil-masked ion implantation”. It consists in implanting silicon ions at ultra-low energy through windows (from 50nm to 2μm) opened in a stencil mask cont ...
The accelerated discoloration of Orange II by an innovative Co3O4/Raschig ring photocatalyst (from now on Co3O4/RR) is feasible and proceeds to completion using oxone as an oxidant within the surprisingly short time of ∼5 min. The preparation of Co3O4 smal ...
We exploited complementary synchrotron radiation spectroscopies to study the Yb 4f electronic configuration in three representative intermediate-valence materials: YbAl3, YbInCu4, and YbCu2Si2. High-resolution x-ray absorption (PFY-XAS), resonant inelastic ...
The oxygen transmission rate of 48 nm thick SiO2 coatings on a poly(ethylene terephthalate) (PET) substrate was reduced by a factor of three after applying an 8 nm thick layer of oligomerized gammaaminopropyltriethoxysilane (γ-APS). Increasing the thicknes ...
The Wien2k code is widely used for the calculation of electron energy loss spectra. Low loss spectra can be calculated with the OPTIC package while core loss spectra are calculated with the TELNES program. A new version, TELNES.2, takes into account the ef ...
The synthesis of nanosized beads of superparamagnetic iron oxide nanoparticles coated with 3-(aminopropyl)triethoxysilane is reported in this paper. The resulting beads are agglomerates of SPIONs with an open fractal like structure. These beads have been e ...
