Tracer diffusion coefficients of Ag+ in silver polystyrenesulfonate and counterion activity coefficients of sodium and silver polystyrenesulfonates have been determined at different concentrations. The results have been ...

Electropolymerisation is a very useful methodology for conducting polymers synthesis. A total comprehension of this process will help on the designing of new materials with improved optical and electrical properties. In ...

The apparent diffusion coefficients for sucrose, NaCl and water during osmotic dehydration of tomatoes in ternary solutions were determined. Long time experiments (up to 60 h) were carried out in order to determine equilibrium ...

Apples (Fuji variety) were treated in aqueous sucrose (50% w/w) and salt (NaCl, 10% w/w) solutions for 2, 4 and 8 h (27 degrees C). Concentration profiles were determined as a function of the distance, considering the ...

Oxygen is an important element for plant growth. Reducing its concentration in the soil affects plant physiological processes such as nutrient and water uptake as well as respiration, the redox potential of soil elements ...
