The oxidation of ferrous sulphate by molecular oxygen under zinc pressure-leach conditions has been investigated. The effects of the variables temperature, acid concentration, zinc sulphate concentration, copper sulphate concentration and the addition of various sulphate salts were studied. An overall ...
Firstly, zinc sulphate and sulfurated potash were dissolved in 450 mL of water separately and filtered. Then, sulfurated potash solution was added to zinc sulfate with stirring. At last, the required amount of water was added and mixed thoroughly and sterilized. For preservative efficacy testing,...
Additionally, the increased size and weight of anions interacting with the Emim+ cation cause the dynamics to become slow. Therefore, due to the higher molecular weight, the BF4− anion has lower diffusion than any other. Indeed, radial distribution functions between cations and anions reveal ...
To cope with very low concentrations of essential ions on mucosal surfaces, Nm carries high affinity uptake systems for those ions. For instance ZnuD has been shown to take up zinc ions at very low concentrations (Stork et al., 2010). Meningococci release small vesicles from the outer ...
Structure elucidation of unknown small molecules by mass spectrometry is a challenge despite advances in instrumentation. The first crucial step is to obtain correct elemental compositions. In order to automatically constrain the thousands of possible ca
[155,182,183]. Recent examples of this include the loading of decellularised ovine pericardial-derived scaffolds with resveratrol, which enhanced their antibacterial, swelling, and water retention capacities [184]. Similarly, the addition of zinc oxide and vitamin c to decellularised caprine small...
Although the molecular weight of the protein (28 kDa) was below the 40–60 kDa threshold for passive diffusion into the nucleus, the resulting protein was observed in both the nucleus and the cytoplasm (fig. 2), clearly different from pMT/pBac-EYFP. The failure of this fusion protein to ...
