MgCl2/NaCl/KCl salt appeared as a high-potential heat transfer fluid for concentrated solar application, offering wide operating range and low cost. Nevertheless, MgCl2 hydrates atmosphere relative humidity are the limiting factors real scale CSP plant, leading to severe corrosion. Thus, Inconel 617 was tested at 700ºC up 24 h in air simulate punctual failure inertization system of plant. XRD S...

The effects of bivalent cations on cytochrome b5 reduction by NADH:cytochrome b5 reductase and NADPH:cytochrome c reductase were studied with the proteinase-solubilized enzymes. Cytochrome b5 reduction by NADH:cytochrome b5 reductase was strongly inhibited by CaCl2 or MgCl2. When 1.2 microM-cytochrome b5 was used, the concentrations of CaCl2 and MgCl2 required for 50% inhibition (I50) were 8 an...

The physicochemical properties of nuclear and cytosolic glucocorticoid-binding components from corticoid-sensitive (CS) and corticoid-resistant (CR) mouse lymphoma P1798 cells have been compared. Nuclei or cytosol fractions were prepared from lymphocytes that had been labeled at 37 or 4 degrees, respectively, with 30 nM [3H]triamcinolone acetonide ([3H]TA). [3H]TA was extracted with 0.6 M KCl, ...

Abstract: To study the effects of inherent and external alkali and alkaline earth metallic species (AAEMs, i.e., K, Ca and Mg) on the behavior of N-containing species release during rice straw (RS) pyrolysis, different pretreatments were applied in numerous experiments. Results indicate that ammonia (NH3) and hydrogen cyanide (HCN) are the major N-containing species and that the yields of isocy...

We have examined binding of the CREB B-ZIP protein domain to double-stranded DNA containing a consensus CRE sequence (5'-TGACGTCA-3'), the related PAR, C/EBP and AP-1 sequences and the unrelated SP1 sequence. DNA binding was assayed in the presence or absence of MgCl2 and/or KCl using two methods: circular dichroism (CD) spectroscopy and electrophoretic mobility shift assay (EMSA). The CD assay...

Transport properties of concentrated electrolytes have been analyzed using classical molecular dynamics simulations with the algorithms and parameters typical of simulations describing complex electrokinetic phenomena. The electrical conductivity and transport numbers of electrolytes containing monovalent (KCl), divalent (MgCl2), a mixture of both (KCl + MgCl2), and trivalent (LaCl3) cations ha...
