PCR is routinely used in detection of antibiotic resistance genes including different classes of tet and erm genes. It remains unknown how PCR conditions affect detection of resistance genes in terms of genetic diversity and prevalence. In this study, numbers of PCR cycles and MgCl2 concentrations were evaluated for their effect on the diversity and prevalence of the tet genes that encode ribos...

Saline soils contain numerous salts with varying impact on seed germination. Seeds of three non-halophytic species found in Chinese sandy deserts (Artemisia ordosica, Aristida adscensionis and Bassia dasyphylla) were incubated in salt solutions (NaCl, KCl or MgCl2, each with or without CaCl2) at 20°C in the dark. The effects of each salt on the percentage of seeds from which visibly detectable ...

Polyelectrolyte multilayers (PEMs) are highly promising materials as selective separation layers on the inside of hollow fiber membranes. We investigate forward osmosis (FO) performance poly(4-styrene sulfonate) (PSS)/poly(allylamine) (PAH)- and PSS/poly(ethylene imine)-based PEM membranes apply different draw solutions. The show properties, demonstrated by their retention behavior under nanofi...

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...
