The group 2 metal halides and corresponding metal halide hydrates serve as useful model systems for understanding the relationship between the electric field gradient (EFG) and chemical shift (CS) tensors at the halogen nuclei and the local molecular and electronic structure. Here, we present a 35/37Cl and 43Ca solid-state nuclear magnetic resonance (SSNMR) study of CaCl2. The 35Cl nuclear quad...

The production of protease by Bacillus licheniformis BBRC 100053 was studied. The most appropriate medium for the growth and protease production is composed of: lactose 1%, yeast extract 0.5%, peptone 0.5%, KH2PO4 0.1%, MgSO4.7H2O 0.02%. Enzyme production corresponded with growth and reached a maximums level (589 U/ml) during the stationary phase at 35°C, pH equivalent to 10 and with 150 rpm af...

In this study, microbial production of L-Dopa and Dopamine which is an important substrance for the treatment Parkinson's disease were investigated by using Citrobacter freundii (NRRL B-2643). The effects carbon source (sucrose) and, salt concentrations (NaCl, CaCl2), initial pH, temperature, inoculum level shaking speed on dopamine investigated. amounts extracellular L-dopa determined HPLC. Ma...

Chloride molten salts have become a potential heat storage material for the design of new generation concentrating solar power (CSP) (>700 °C) due to its abundant reserves and low cost. The difficulty measuring high-temperature thermal properties chlorides can be effectively solved by using molecular dynamics simulation. However, it is challenging get thermophysical multi-component containin...

In this study, the O3 and OH radical oxidation of 2,5-dimethylfuran (2,5-DMF) were investigated in two different chambers at (296±1) K atmospheric pressure to examine secondary organic aerosol (SOA) formation. Results for OH-photooxidation indicate that SOA yieldsdecrease (from 6.2 0.4) with rise 2,5-DMF concentration (from10 1000 ppb). absence NOx under high relative humidity (RH) conditions (...

Two experiments were conducted to determine the optimum protocol for maximizing meat quality with CaCl2 injection. Experiment 1 compared the effects of 30 min or 24 h postmortem injection of 175 mM CaCl2 or water at 10% (wt/wt) to controls on various measures of meat quality. An injection of CaCl2 reduced (P < .05) shear force values in all three beef muscles evaluated (longissimus, semimembran...

‘Golden Delicious’ apples (Malus domestica Borkh) were pressure-infiltrated at harvest with a 4% CaCl2 solution either without prior heat treatment or following 4 days at 38C. Examination of the apple surfaces from both treatments by low-temperature scanning electron microscopy revealed that heat treatment changed the pattern of epicuticular wax. The epicuticular wax of nonheated fruit exhibite...
