Understanding the relation between the structure and the reactivity of nanomaterials in the organism is a crucial step towards efficient and safe biomedical applications. The multi-scale approach reported here, allows following the magnetic and structural transformations of multicore maghemite nanoflowers in a medium…
Chromium oxide (Cr2O3) nanoparticles were synthesized using a sol-gel method and mixed with polyvinyl chloride (PVC). Rietveld refinement of X-ray powder diffraction (XRD) patterns of the samples revealed that the crystal structure of Cr2O3 is rhombohedral with space symmetry group. Scanning electron microscopy images…
Grain boundaries are shown to play a critical role in controlling electron mobility in nanocrystalline titanium dioxide affecting material performance for applications such as solar energy generation and catalysis. Theoretical modelling demonstrates that electron mobility can be reduced by several orders of magnitude…
In the supramolecular photocyclodimerization of 2-anthracenecarboxylate mediated by 6(A),6(D)-diguanidino-γ-cyclodextrin (CD), the chiral sense and enantiomeric excess of the photoproduct were dynamic functions of temperature and cosolvent to afford the (M)-anti head-to-head cyclodimer in 64% ee in aqueous methanol at…
Wetting-transparent graphene films grown in situ by chemical vapor deposition on hydrophobic (roughened) copper surfaces offer excellent resistance to copper corrosion while maintaining the intrinsic hydrophobicity of the surface, enabling superior performance for water-harvesting applications.
Single crystals of ice Ih, extracted from the subglacial Lake Vostok accretion ice layer (3621 m depth) were investigated by means of diffuse x-ray scattering and inelastic x-ray scattering. The diffuse scattering was identified as mainly inelastic and rationalized in the frame of ab initio calculations for the ordere…
The largest obstacles for landfill/flue gas separation using microporous materials are small adsorption values and low selectivity ratios. This study demonstrates that these adsorption and selectivity challenges can be overcome by utilizing a series of hyper-cross-linked heterocyclic polymer networks. These microporou…
Cette étude a fait l'objet de deux parties. L'une porte sur l'effet de différents types d'activation (chimique, thermique, mécanique) de kaolins (géo-matériaux riches en kaolinite) sur leurs propriétés de décoloration vis-à-vis de l'huile de riz. L'autre traite de l'effet de la taille et de la morphologie de kaolinite…

This is rather cranking the handle, but taking my previous post and altering the search definition of the crystal structure database from 4- to 5-coordinate metals, one gets the following. Fe … Co … Ni … Cu … Trigonal bipyramidal coordination has angles of 90, 120 and 180°. Square pyramidal has no 120° angles, and the…

We report a technique to realize reconfigurable colloidal crystals by using the controlled motion of particle defects above an externally modulated magnetic substrate. The transport of particles is induced by applying a uniform rotating magnetic field to a ferrite garnet film characterized by a periodic lattice of mag…
Soft and biological matter is governed by three fundamental interactions. Two of them are long-ranged, namely the van der Waals and electrostatic forces. For large separations, these two contributions can be treated in a continuum formulation in terms of Derjaguin-Landau-Verwey-Overbeek (DLVO) theory [1]. In this appr…
