two new nano-sized lead(ii) and mercury(ii) coordination polymers, [pb(2-bpdh)(no3)2(h2o)]n(1); (2-bpdh = 2,5-bis(2-pyridyl)-3,4-diaza-2,4-hexadiene)} and [hg(4-bpdb)(scn)2]n (2); (4-bpdb= 1,4-bis(4-pyridyl)-3,4-diaza-1,3-butadiene) were synthesized by a sonochemical method. the structure of 1 may be considered coordination polymer of lead(ii) and single crystal x–ray analysis of compound 2reve...
Numerical methods for the calculation of the acoustic field inside sonoreactors have rapidly emerged in the last 15 years. This paper summarizes some of the most important works on this topic presented in the past, along with the diverse numerical works that have been published since then, reviewing the state of the art from a qualitative point of view. In this sense, we illustrate and discuss ...
A comprehensive investigation of ultrasonic frequency and its role in sonochemical activity and sonoluminescence (SL) has been performed. SL spectra and intensity were examined at four frequencies (205, 358, 618, and 1071 kHz) and in the presence of varying argon and oxygen saturation ratios. A series of highenergy reactions induced by the extreme temperatures and pressures obtained within a mi...
