A relevant research effort is devoted to the synthesis and characterization of phases belonging to the ternary system Cu–Sn–S, mainly for their possible applications in semiconductor technology. Among all ternary phases, kuramite, Cu3SnS4, mohite, Cu2SnS3, and Cu4Sn7S16 have attracted the highest interest. Numerous studies were carried out claiming for the description of new phases in the terna...

Lagos State has grown from 300,000 and 500,000 in 1950 and 1991 to an unprecedented population of 15.7 million (Mabogunje, 2002). Already, it is projected to have a population of 25 million by 2015 which will make Lagos the third largest megacity after Tokyo and Bombay and a population of 29 million by 2020, w ith an annual grow th rate of 8 %( UNCHS, 1996; George, 2010; LWC, 2011). This scenar...

Previous results on apple tissue equilibration during osmotic dehydration showed that, at very long processing times, the solute concentrations of the fruit liquid phase and the osmotic solution were the same. In the present study, changes in apple liquid phase composition throughout equilibrium in osmotic dehydration were analyzed and modeled. Results showed that, by the time osmosed samples r...

We have experimentally determined the coexistence surface characterizing the phase behavior of gammaD-betaB1-water ternary solutions. The coexistence surface fully describes the solution conditions, i.e., temperature, protein concentration, and protein composition, at which liquid-liquid phase separation occurs in a ternary solution. We have observed a significant demixing of gammaD and betaB1 ...

Ion-exclusion chromatography (IEC) finds applications in various different analytical separations of weak acids. Pure, deionized water or a diluted, aqueous solution of a strong mineral acid (such as, e.g., sulphuric acid) is used as the mobile phase, whereas a typical stationary phase is a strongly acidic resin in the H(+) form (e.g., the sulfonated polystyrene-divinylbenzene resin with a high...
