The difference between the inter-diffusion kinetics of K+ Na+ in the air and tin sides of an ion-exchanged float aluminosilicate glass was investigated as a function of the exchange temperature and time.
There has to be a separation between the business and regulatory functions of the exchange".
The instantaneous concentration of a solute in single toluene droplets in water phase was measured contactless as function of the exchange time during non-stationary mass exchange by means of a modified liquid scintillation technique using two photomultipliers in coincidence, a three channel spectrometer and multichannel analyser.
The instantaneous solute concentration in freely suspended single droplets were measured as function of the exchange time by means of a radionuclide technique with and without chemical reaction in liquid liquid systems in several drop sizes covering the range of Reynolds numbers 114 443.
For the first time we have determined the quantitative amount of the metastable phase in the shell as a function of the exchange time and the shell thickness.
When the intensity of these peaks are plotted against each other as a function of the exchange mixing period at 43°C, an exchange lifetime of 3.0 s is obtained.
We aim in this study to retrieve the quantitative amount of the RS ZBB phase ratio within the shell as a function of the exchange time and the shell thickness.
In Figure 3c we depict the PL emission of all three sample series also as a function of the exchange time and can thus relate the optical performance of the core/chell NCs to their different structural and chemical compositions.
The amounts of Pb derived from both methods, RBS and ASAXS, are in very good agreement as can be seen in Figure 3d, where the Pb-concentration is plotted as a function of the exchange time.
It was found that while the functions of the exchanges produced by the ESL learners were mostly announcing, reacting, questioning, advising, and justifying, those exchanges of the native speakers were confirming, pointing, hedging, elaborating, and eliciting.
