First, added 0.01 wt % of GO to molten caprolactam (100 g) and sonicated
the mixture at 85[degrees]C for 30 min to obtain a homogeneous dispersion.

GO NPs and (b) sonicated
The pristine and functionalized CNTs were diluted in distilled water and sonicated
for 30 minutes at 40[degrees]C.
To modify the surface of CC electrode being hydrophilic, the CC was immersed in the mixture of acids ([H.sub.2]S[O.sub.4]: HN[O.sub.3] = 3:1) and then sonicated
for 5 min to produce hydrophilic carboxyl functional group (COOH) .
Co[Fe.sub.2][O.sub.4]-NPs were freshly suspended at 1 mg/mL concentration in cell culture medium with 10% FBS and sonicated
at room temperature for 15 min to avoid the aggregation/agglomeration of the nanoparticles before exposure.
Cells were sonicated
for 15 sec with 60 sec interval (5 cycles) and centrifuged (1500 xg, 10 min) at 4degC.
200 grams of the dried sweet violet flowers were soaked in flask with 1000 mL of 80% methanol, sonicated
for 24 hours, filtered with whatman no.2 filter paper, took the residue on filter and sonicated
for more 24 hours and extracted once more (1000 mL each time).
The mixture was sonicated
for 45 minutes and the resulting solution was cooled overnight in a refrigerator.
The cells were harvested and sonicated
. The lipases (LK2, LK3, and LK5) were expressed as soluble form of proteins.
Next, they were sonicated
to ensure good dispersion and measured using ICP-AES instrument.
In 100 ml measuring flask 30 mg of caffeine was transferred, added 80 ml mobile phase, sonicated
to dissolve and again mobile phase was added to made volume up to the mark.
