In this study, we investigate the effects of the duration of ultrasonic treatment during the
impregnation process of a carbon precursor with an aqueous alkaline solution on the …

Ultrasound irradiation is a technique that can induce acoustic cavitation in liquids, leading to
a highly interactive mixture of reactants. In pursuit of high-performance and cost-effective …

Glassy carbon particles (millimetric or micrometric sizes) dispersions in water were treated
by ultrasound at 20 kHz, either in a cylindrical reactor, or in a “Rosette” type reactor, for …

Biological activated carbon (BAC) filter has been widely used as an effective water treatment
but regenerations of BAC are costly. Ultrasound has been successfully applied for …

The influence of ultrasonic radiation in the cavitation regime on the structural properties of
activated carbon was studied. It was established, as the result of the X-ray diffraction, small …

In general, the activation of lignin involves acid demineralization followed by a chemical
treatment under an inert atmosphere at a high temperature. The whole process is tedious …
