The use of copper tailings as supplementary cementitious material can reduce the environmental impacts concrete production and mining industry. A key concern limiting its application is potential leaching toxic metals from matrix, especially copper. To analyze risk leaching, mechanisms by which entrapped in matrix were investigated, combining microscopic spectroscopic approaches. Decreasing wat...

This integrated study provides significant insight into parameters controlling the dynamic and static elastic behaviors of shale. Acoustic geomechanical measurement from laboratory have been coupled with detailed petrographic geochemical analyses, microtexture observations on shale samples Wufeng?Longmaxi Formation southeast Sichuan Basin. The major achievement is establishment link between dep...

Non-derivatised cellulose is generally assumed to have poor surface activity and therefore be unsuitable as a water in oil (W/O) emulsifier. In this work, “natural” microgel (CMG) fabricated via top-down approach used stabilize W/O emulsions, without employing chemical modification. The coagulated from an ionic liquid through solvent-exchange process, the presence absence of added sunflower oil...

Abstract The Seve Nappe Complex (SNC) comprises continental rocks of Baltica that were subducted and exhumed during the Caledonian orogeny prior to collision with Laurentia. tectonic history central SNC is investigated by applying in-situ zircon monazite (Th-)U–Pb geochronology trace element analysis (ultra-)high pressure (UHP) paragneisses in Avardo Marsfjället gneisses. Zircons Gneiss exposed...

Abstract The ionoSolv process is one of the most promising technologies for biomass pretreatment in a biorefinery context. In order to evaluate transition from bench-scale experiments commercial scale, there need get better insight intensification. this work, effects loading, particle size, pulp washing protocols and 100-fold scale up grassy Miscanthus giganteus with IL triethylammonium hydroge...

The Sargaz granitic intrusion has been emplaced in Sargaz ophiolitic suite, south-east of Sanandaj-Sirjan metamorphic zone, south of Kerman province. The central part of the intrusive body contains pinkish coarse-grained granite, but the fractured northern part, neighboring Chah-Mazraeh fault, has been subjected to pervasive Na-metasomatism and related subsolidus reactions. In the northern alte...

A new D-A-π-A-D molecule (Spiro-BTA) containing two 2,1,3-benzothiadiazole (BTA) as the acceptor (A) and triphenylamine as the donor (D) bridged by a spirobifluorene moiety has been synthesized. The novel D-A molecule shows intense red emission (612 nm) with a high PL quantum yield (Φ(PL) = 0.51) in a solid film. A cyclic voltammogram of Spiro-BTA in 1:2 MeCN:benzene/0.1 M Bu(4)NPF(6) shows two...

Disposing of plastic wastes to landfill is becoming undesirable due to legislation pressures, rising costs and the poor biodegradability of commonly used polymers. In addition, incineration meets with strong societal opposition. Therefore, recycling either mechanical or chemical, seems to be the only route of plastic wastes management towards sustainability. Polyolefins, mainly polyethylene (LD...

Tourmalines are a group of minerals which may concentrate various accessory 16 components, e.g. Cu, Ni, Zn, Bi, Ti, Sn. The paper presents fluor-elbaite and elbaite from a dyke of 17 the Julianna pegmatitic system at Piława Górna, at the NE margin of the Bohemian Massif, SW 18 Poland, containing up to 6.32 and 7.37 wt.% ZnO, respectively. Such high amounts of ZnO are 19 almost two times higher ...

Currently, performance assessment (PA) modelling for nuclear waste repositories reliesheavily on the Kd approach which empirically averages contaminant retardation over a range ofconditions in the hope that uncertainties are treated conservatively. Mechanistic approaches arerare or non-existent, often because of lack of information. However, recently developed high-resolution, s...
