A new concept of critical point is expounded by analysing the potentiometric titration curves of aluminium salt solutions under the moderate slow rate of base injection. The critical point is defined as the characteristic spot of the Al salt solutions potentiometric titration curve, which is related to the experiment conditions. In addition, the changes of critical points reflect the influence ...
We have explored the refractive index changes (RIC) in single-mode aluminum silicate ytterbium-doped optical fibers induced by optical pulses at 980 nm and report dynamical fundamentals of the process. The RIC dynamics is shown to follow the population dynamics of the excited and unexcited ions with a factor proportional to their polarizability difference (PD). The PD dispersion profile indicat...
The effect of chemical composition on the Raman spectra of a series of natural calcalkaline silicate glasses has been quantified by performing electron microprobe analyses and obtaining Raman spectra on glassy filaments (~450 µm) derived from a magma mingling experiment. The results provide a robust compositionally-dependent database for the Raman spectra of natural silicate glasses along the c...
