Carbonate dissolution by euendolithe cyanobacterium
Bioerosion is the process of destruction of rocks by living organisms. The bioerosion of biogenic carbonates by so-called "euendolithic" cyanobacteria (which live in rocks) is a major but poorly quantified process, causing, among other things, the disintegration of coral reefs. Euendolitic ...
Impact of a treatment by plasma polymerization on the filtration performances of commercial membranes for the decontamination of solution containing metal ions.
In this project, a commercial membrane exhibiting low performances of heavy metal removal has been modified by plasma grafting of poly(allylamine). This treatment allows modifying the structural and physicochemical properties of the membrane surface and thus increasing separation performances, while ...

Control of Structures and Emission Properties of (CuI)n 2-Methyldithiane Coordination Polymers
A structurally unique and strongly luminescent nonporous 3D coordination polymer (CP) [Cu8I8(methyldithiane)4]n, CP3, has been prepared in a quasi-anticipated manner from 2-methyl-1,3-dithiane, L1, and CuI. This CP incorporates an unprecedented Cu8I8 cluster built upon two side-fused open cubanes. ...
A Fused Poly(truncated rhombic dodecahedron)-Containing 3D Coordination Polymer: A Multifunctional Material with Exceptional Properties
The design of new and inexpensive metal-containing functional materials is of great interest. Herein is reported a unique thermochromic near-IR emitting coordination polymer, 3D-[Cu8I8(L1)2]n, CP2, which is formed when ArS(CH2)4SAr (L1, Ar = 4-C6H4OMe) reacts with 2 equiv of CuI in EtCN. In MeCN, ...

Crystal structure of the coordination polymer catena-poly[[[(acetonitrile-κN)copper(I)]-μ3-1,3-dithiolane -κ3S:S:S'] hexafluoridophosphate]
The polymeric title compound, [Cu2(C2H3N)2(C3H6S2)2](PF6)2, represents an example of a one-dimensional coordination polymer resulting from the reaction of [Cu(MeCN)4][PF6] with 1,3-dithiolane. The cationic one-dimensional ribbon consists of two copper(I) centers each ligated by one acetonitrile ...
Unusual Triplet-Triplet Annihilation in a 3D Copper Chloride Coordination Polymer
A new coordination polymer (CP) defined as [Cu2Cl2(EtS(CH2)4SEt)4]n (CP2) was prepared by reacting EtS(CH2)4SEt with CuCl in acetonitrile in a 1 : 2 stoichiometric ratio. The X-ray structure reveals formation of non-porous 3D material composed of parallel 2D-[Cu2Cl2S2]n layers of Cl-bridged ...
Clay mineralogical and geochemical expressions of the "Late Campanian Event" in the Aquitaine and Paris basins (France): Palaeoenvironmental implications
Campanian sediments from two French sedimentary basins were studied, using clay mineralogy and stable isotope (δ13C and δ18O) geochemistry, in order to investigate the Late Campanian Event. The clay fraction of the Campanian sediments from the Tercis-les-Bains section (Aquitaine Basin) and from the ...
Bis{(4-methylthio)phenylthio}methane as assembling ligand for the construction of Cu(I) and Hg(II) coordination polymers. Crystal structures and topological (AIM) analysis of the bonding
The novel 1D coordination polymer (CP) [{Cu(μ2-Br)2Cu}(μ-L2)2] CP2 has been obtained by reaction of the tetrakisthioether p-MeSC6H4SCH2SC6H4SMe-p (L2) with CuBr in a 1:2 metal-to ligand ratio. In contrast to the previously described CP [{Cu(μ2-Br)2Cu}(μ-L1)2] CP1 obtained by reaction of the ...
