Effect of different gases on the sonochemical Cr(VI) reduction in the presence of citric acid
(Pergamon-Elsevier Science Ltd, 2020-12)
The sonochemical (850 kHz) Cr(VI) reduction (0.30 mM, pH 2) in the presence of citric acid (Cit, 2 mM) was analyzed under different working atmospheres: reactor open to air without sparging (ROAWS), and Ar, O2, air and N2 ...

Limit cycles in the spectra of mass imbalanced many-boson system
(2020-10-29)
The independence between few-body scales beyond the van der Waals universality is demonstrated for the extreme mass-imbalanced case of a specific many-boson system. This finding generalizes the scaling properties of universal ...
