Full textThe objective of this work was to establish the binding properties of oxacalix[4]arene derivatives with different numbers of the oxa bridges, functional groups (ketones, pyridine, ester, amide and methoxy) and conformations. Their interactions with alkali and alkaline-earth, heavy and transition metal cations have been evaluated according to different approaches: (i) extraction of corresponding picrates from an aqueous phase into dichloromethane; (ii) determination of the thermodynamic parameters of complexation in methanol and/or acetonitrile by UV-spectrophotometry and microcalorimetry; (iii) determination of the stoichiometry of the complexes by ESI-MS; (iv) 1H-NMR titrations allowing to localize the metal ions in the ligand cavity. In a first part dealing on homooxacalix[4]arenes, selectivities for Na+, K+, Ca2+, Pb2+ and Mn2+ of ketones derivatives was shown. The presence of oxa bridge in these derivatives increases their efficiency while decreasing their selectivity with respect to related calixarenes. The pyridine derivative prefers transition and heavy metal cations, in agreement with the presence of the soft nitrogen atoms. In the second part, dioxacalix[4]arene ester and secondary amide derivatives were shown to be less effective than tertiary amide counterparts but to present high selectivities for Li+, Ba2+, Zn2+ and Hg2+. A third part devoted to the octahomotetraoxacalix[4]arene tetramethoxy shows that the 1:1 metal complexes formed are generally more stable than those of calixarenes, suggesting the participation of the oxygen atoms of the bridge in the complexation. Selectivity for Cs+, Ba2+, Cu2+ and Hg2+ were noted

Full textThe metalla-alcynes of group 14 –M=C- (M = Si, Ge, Sn) is a new function of organometallic chemistry, this function appears extremely promising both in terms of fundamental applied. Indeed, if the study of a new link carbon presents a clear fundamental interest, these derivatives appear especially promising for their many potential applications: organometallic precursor polymer, new ligands for transition metals chemistry, catalysis. . . No germa-alcyne has been isolated to date and a single instance, short-lived, has been characterized within our team by trapping reaction. Our strategy to prepare for such molecules involves the photochemical decomposition of a diazogermylene. In this work our effort focused more specifically on the search for substituents that could stabilize these species by electronic and steric effects. We used a new ligand (Ar = 2-diisopropylaminoethyl-4,6-ditertbutylphényl) which has the interest to add to the effect steric effect of a coordinated electronic intramolecular N> Ge. The photochemical decomposition led well then, after starting nitrogen at germa-alcyne Ar-Ge?C-SiMe3. This is the 2nd germa-alcyne known, it has been characterized by its reaction with water and tertiobutanol. The diazogermylène also offers an original and rich chemistry; it is possible to achieve particularly germathione, germa-selenone and germa-tellurone> = Ge Y (Y = S, Se, Te) surprisingly stable condition and whose monomer there are few examples

Full textMonte Carlo and Molecular Dynamic simulation methods have been performed to study hydrated Wyoming-type montmorillonite, a naturally occurring swelling clay, including different monovalent or divalent counterions. Simulations have been also performed to investigate the swelling and shrinking behaviour of montmorillonite under the influence of water content, temperature and different counterions. We found a general phenomenon of hysteresis during both the hydrate/dehydrate and the warming/cooling processes. The quantities of counterions together with their solvation characteristics and their attraction capacities have an important influence on the swelling and shrinking behaviours of this clay. Moreover, investigations on the diffusion behaviours of water and counterions in the interlayer space of montmorillonite show the effect of hydrated degree and different existing cations especially the pollutants on the diffusion of water, as well as the effect of temperature on the diffusion of interlayer particles. The agreement of our simulation results on the clay containing some common cations such as Li+, Na+, K+ and Ca2+, with available experiment and preceding theoretical works, permitted us to extend our study to the clay with heavy metal ions, such as Rb+, Cs+, Ni2+, Zn2+ and Pb2+, some of which have never been studied.Finally, detailed studies on the shrinking behaviours of hydrated montmorillonite under pressure allowed us to shed light on the rigidity of this clay affected by the hydrated degree, where we found a phase transition phenomenon in hydrated montmorillonite with the phase transition pressure less than 1GPa. According to our calculations the bulk modulus reaches extremely high values at modest pressures of ~20 GPa. It would open a route to a new family of ultra-incompressible materials of clay composition. Such materials, and their superior mechanical properties and possibly low cost, could be practically attractive for a number of uses

Full textThe present work deals with the hydrothermal synthesis of 2:1 phyllosilicate with a saponite type-like structure in fluoride medium and the soft and direct synthesis of 2:1 organophyllosilicates. The effects of the different parameters controlling the presence of aluminum in the tetrahedral sheet were studied. Saponite was only obtained for a low substitution rate of aluminum in fluoride and acidic medium, whereas high substitution rate in basic medium has been provided a saponite-like structure. A proposition of a formation mechanism is given. In basic medium, the 2:1 phyllosilicate structure is induced by the hydrotalcite formation and in acidic medium by the polysilicic acid formation. Different kind of hybrid lamellar materials were also prepared : a lamellar organoaluminosilicate having no phyllosilicate structure, a lamellar organomagnesoaluminosilicate having, as inorganic parent, a 2:1 phyllosilicate structure. A formation mechanism was proposed. These materials are very interesting in the chelating of heavy metal cations

Full textToutes ces populations sont tolerantes et accumulatrices de quantites tres importantes de zn et de cd. La tolerance a ces metaux ainsi que leurs accumulations semblent etre des proprietes constitutives de l'espece. L'etude de la descendance (f2) d'un croisement interspecifique, (a. Halleri tolerant-hyperaccumulateur) x (a. Petraea non-tolerant-non-accumulateur), a montre que la tolerance au zn semblait etre sous le controle d'un gene majeur tandis que la variation du degre de tolerance au zn semblait etre sous le controle de genes modificateurs. La tolerance au zn n'est pas due aux metallothioneines. Elles pourraient, cependant, contribuer a modifier le degre de tolerance au zn et ainsi intervenir au titre de modificateur. Les resultats preliminaires obtenus sur la tolerance et l'accumulation du cd en relation avec la tolerance et l'accumulation du zn suggerent l'independance des mecanismes lies au cd et au zn

Full textRastolnia eutropha CH34, formerly Alcaligenes eutrophus CH34, was initially isolated from a decantation tank by Houba et al. , in 1976. Studies on this strain revealed at least 11 heavy metals resistances, carryied by two megaplasmids : pMOL28 et pMOL30, which translate a bacteria adaptation system to highly polluted soils. Firstly, the czc resistance system, carried by pMOL30, is based on cadmium, zinc and cobalt efflux. Secondly, Rastolnia eutropha CH34 had developed a highly specific system for iron transport, based on siderophore affinity, because this element is weakly biodisponible in environment. These two mechanisms, the first one facultative, and the second one inducible but constitutive, seem to be associated. The knowledge of these two mechanism is very important to understand the way of heavy metal depollution processes. The main purpose of this study was to identify the proteins of czc system and the siderophore-iron receptor. Two Rastolnia eutropha CH34 derivates were used as references : Rastolnia eutropha 1153 (which overexpresses siderophores) and Rastolnia eutropha 104 which is plasmids-free). A 45kDa outer membrane protein was identified, by electrophoresis techniques. It seems to be the siderophore-iron receptor
