The subsequent annealing process further transforms the melamine absorbed on the surface of graphene into melon (C6N9H3)x, which is one type of condensation product of melamine, and simultaneously dopes the graphene with nitrogen.
Thus, more amine molecules can be absorbed on the surface.
In that case the nitrate anions should be absorbed on the surface of the nanoparticles.
In our case, PAA absorbed on the surface improves the hydrophilicity and biocompatibility of the nanoparticles.
Upon addition of NaCl into the BAgNP, the Cl− ions were absorbed on the surface of BAgNP in a triangle, and the remnant H2O2 can be also absorbed on the surface.
And H + ions can also be absorbed on the surface of the nanowires, acting as extra carriers [14, 55].
When the Fe3O4 NPs were produced, the Fe3+ ions were absorbed on the surface of the Fe3O4 NPs.
One end of C18H33O2 − plunges into the solution, and another end was absorbed on the surface of nanoparticles.
The organic coating of PEG resists the nitrogen to be absorbed on the surface of ZnO particles.
The unreacted ions are absorbed on the surface of the newly formed clusters to form a charged cluster.
Secondly, the SF nanoparticles absorbed on the surface of R-GO have high dispersion, which can improve magnetic loss [55].
