In the present work we systematically studied hydrolysis of magnesium hydride in MgCl2 aqueous solutions, which was used as a process promotor. The initial rate, pH reaction mixture, and overall yield are all found to be linearly dependent logarithm concentration. phase-structural elemental compositions formed precipitates showed that they do not contain chlorine ions solely consist Mg(OH)2. si...

Thermochemical energy storage (TcES) is a promising technology for advanced storage. This study investigated the reaction of magnesium chloride (MgCl2) and ammonia (NH3) as TcES material at approximately 100°C. Activation through NH3 absorption desorption was confirmed to increase MgCl2 surface area from 2.60 73.3 m2 g−1 create mesopores. Superior reactivity demonstrated with maximum rate 0.019...

heterogeneous ziegler-natta and homogeneous metallocene catalysts exhibit greatly different active sitenature in olefin polymerization. in our previous study, it was reported that mgcl2-supported titanocenecatalysts can generate both ziegler-natta-type and metallocene-type active sites according to the type of activators.the dual active site nature of the supported titanocene catalysts was furt...

The interaction of amphotericin B methyl ester (AME) with protoplasts of Candida albicans was measured indirectly by following the incorporation of [U-14C]phenylalanine into the acid-insoluble material. The inhibitory effects of AME at the minimum inhibitory concentration were prevented by the addition of 85 mM-KCl and 45 mM-MgCl2, as shown by Liras & Lampen (1974) for Saccharomyces cerevisiae....

The stepwise chromatographic behaviour on DEAE-Sepharose of rat Fe65, a neuronal protein, was tested, using as eluants KCl, CaCl2, and MgCl2. Assays by western blot showed that Fe65 was eluted by CaCl2, at a ionic strength 20% lower than that of MgCl2 or KCl. Interestingly, in the case of a truncated Fe65, lacking a glutamic acid rich region at the N-terminus, the ionic strengths of the various...

Transcription from P2, one of the major promoters of the cell wall protein gene operon of Bacillus brevis 47, was markedly enhanced at the early stationary phase of growth. MgCl2, when added at 1 to 5 mM to the medium, inhibited this enhancement of transcription as well as shedding of the cell wall protein layers from the cell surface. MgSO4 or CaCl2 showed an effect similar to that of MgCl2. T...

The photosynthetic oxygen-evolving activity of the photosystem 2 complex, prepared from spinach, was labile when the complex was exposed to high-salt conditions under which the extrinsic proteins were dissociated from the complex. Glycinebetaine prevented the dissociation of the 18-kDa and the 23-kDa extrinsic proteins from the photosystem 2 complex in the presence of 1 M NaCl. It also prevente...
