20.11.2020The intermittent ball milling procedure, in which the ball mill operates for 6 min with a pause of 3 min, was employed. The ball milling was carried out for total 9 h at a rotational speed of 400 r min −1. The suspension was subsequently filtered out and dried. The so-obtained ATP sample was collected and designated as bp-ATP.
