Two copper(II) complexes, both involving the anionic 3,5-bis(trifluoromethyl)benzoate ligand (TFMBz), have been prepared and their structure elucidated by single crystal-X ray diffraction. [Cu(TFMBz)2(ISNA)2] (1) is a mononuclear complex, in which the sphere of coordination of Cu(II) is completed by two neutral isonicotinamide (ISNA) auxiliary ligands. [...]

Here, we report the design, synthesis, and functional testing of enzyme-powered porous micromotors built from a metal-organic framework (MOF). We began by subjecting a presynthesized microporous UiO-type MOF to ozonolysis, to confer it with mesopores sufficiently large to adsorb and host the enzyme catalase (size: 6-10 nm). [...]

14 p, 2.5 MB Clay minerals formed during propylitic alteration of a granite and their influence on primary porosity : A multi-scale approach / Cassiaux, M. (University of Poitiers) ; Proust, D. (University of Poitiers) ; Siitari-Kauppi, M. (University of Helsinki) ; Sardini, P. (University of Poitiers) ; Leutsch, Y. (ANDRA)
The porosity of a propylitized granite from Charroux (France), with no fractures or sealed fractures, inreases by more than four times from the unaltered (0. 3%) to the altered rock (1. 4%). This evolution results from several local porosity modifications which occur at different scales in the rock: (1) at the core scale, from 10 to 10 m, where rock porosity changes as a function of rock-forming mineralogical composition; (2) at the mineral scale, from 10 to 10 m, where porosity depends both on the nature of the rock-forming mineral and its clay mineral alteration.

9 p, 839.9 KB Some physicochemical properties of the white sepiolite known as pipestone from Eski̇şehi̇r, Turkey / Önal, Müserref (Ankara University. Department of Chemistry) ; Yilmaz, Hamza (Ankara University. Department of Chemistry) ; Sarikaya, Yüksel (Ankara University. Department of Chemistry)
Various physicochemical characteristics of a sepiolite sample from the Eskişehir area, Turkey, were investigated to help in making predictions about possible uses of the material. The sample was examined by chemical analysis (CA), thermal analysis (DTA/TGA), X-ray diffraction (XRD) analysis, particle-size analysis (PSA), linear dilatometry (LD), scanning electron microscopy (SEM), mercury porosimetry (Hg-Por.

16 p, 1.2 MB Effect of the size of aggregates on pore characteristics of minerals measured by mercury intrusion and water-vapor desorption techniques / Jozefaciuk, Grzegorz (Institute of Agrophysics of the Polish Academy of Sciences)
The size, shape, and continuity of pores in mineral solids greatly influence the behavior of percolating liquids and solids in porous media, which has significant practical environmental implications. [...]

15 p, 2.3 MB Mineral preferred orientation and microstructure in the Posidonia Shale in relation to different degrees of thermal maturity / Kanitpanyacharoen, Waruntorn (University of California. Department of Earth and Planetary Science) ; Kets, Frans B. (University of Leeds. School of Earth and Environment) ; Wenk, Hans-Rudolf (University of California. Department of Earth and Planetary Science) ; Wirth, Richard (GeoForschungsZentrum)
The thermal maturity of samples of the Posidonia Shale collected from the Hils Syncline, northern Germany, varies significantly as a function of location indicating variations in local history. Synchrotron X-ray diffraction was used to document the composition and the preferred orientation of four samples of the Posidonia Shale with different degrees of maturity (0. [...]

We report the use of bis-catecholic polymers as candidates for obtaining effective, tunable gatekeeping coatings for mesoporous silica nanoparticles (MSNs) intended for drug release applications. In monomers, catechol rings act as adhesive moieties and reactive sites for polymerization, together with middle linkers which may be chosen to tune the physicochemical properties of the resulting coating.
