This study focused on the preparation, structural characterization and evaluation of some dynamic rheological properties a new type mastic material, clay-mastic, which consists bituminous binders mixed with mineral fillers. For this purpose, samples were prepared by mixing conventional bitumen (50/70) organo-montmorillonite (OMMT) in various proportions. X-ray powder diffraction (XRD) spectra s...

Correction for ‘Sustainable pathway to furanics from biomass via heterogeneous organo-catalysis’ by Sanny Verma et al. , Green Chem. 2017, 19 164–168, https://doi.org/10.1039/C6GC02551J.

A simple and mild catalytic coupling reaction of propargyl halides with organotitanium reagents is reported. The reaction of propargyl bromide with organo-titanium reagents mediated by NiCl2 (2 mol%) and PCy3 (4 mol%) in CH2Cl2 afforded coupling product allenes in good to excellent yields (up to 95%) at room temperature. However, NiCl2(PPh3)2 was the best catalyst for substituted propargyl hali...

With the aid of more sensitive instrumental methods it is possible to determine trace elements after separation of different fractions from soil and plant samples. Fractions of soils and sediments are obtained by extraction with different reagents, chosen in function of biological, ecological or chemical considerations. In plant samples it is possible to separate free ions and organo-mineral co...

Results of ab initio molecular orbital studies are presented for one elementary reaction and two full catalytic cycles of organo-transition metal complexes: (i) the oxidative addition of H-H, C-H, N-H, 0-H and Si-H bonds to CpRh(C0) in gas phase, (ii) the full catalytic cycle of hydroboration of olefin with Rh(PR3)2Cl, and (iii) the full catalytic cycle of hydroformylation of olefin with RhH(C0...

A photolabile ruthenium-based complex, [Ru(bpy)2 (4AMP)2 ](PF6 )2 , (4AMP=4-(aminomethyl)pyridine) is incorporated into polyurea organo- and hydrogels via the reactive amine moieties on the photocleavable 4AMP ligands. While showing long-term stability in the dark, cleavage of the pyridine-ruthenium bond upon irradiation with visible or near-infrared irradiation (in a two-photon process) leads ...

The controlled bottom-up design of polymers with metal oxide backbones is a grand challenge in materials design, as it could give unique control over the resulting chemical properties. Herein, we report 1D-organo-functionalized polyoxometalate polymer featuring purely inorganic backbone. self-assembled from two types monomers, Wells–Dawson-type polyoxometalates, and aromatic organo-boronates. T...

The interface properties of Fe(101)/zinc silicate modified by organo-siloxane (KH-570) was studied using the method molecular dynamics simulation. By calculating temperature and energy fluctuation equilibrium state, concentration distribution, MSD layer different groups, interaction two models, influencing mechanism on adding organosiloxane into coating system at atomic scale. It shows that osc...

the present article reports on the application of modified organo nanoclay as a green, easily prepared and stable solid sorbent for the preconcentration of trace cobalt ion in aqueous solution. the organo nanoclay was modified by adsorption of 5-(4-dimethyl amino-benzylidene) rhodanin reagent onto it. the sorption of co2+ ions was quantitative in the ph range of 7.0 to 8.5, whereas quantitative...
