However, when comparing the mass ratio of sodium acrylate to water glass, it was found that the same sample with a different monomer content polymerized faster when the content was lower.
However, at the mass ratio of 1:4, the averaged crystalline size of TiO2 was increased again and the diffraction peak of cubic CeO2 became stronger, but the peak at 2I,=8.24o for Pal was almost disappeared, which might be related with the reduction of TiO2 particles, inducing the aggregation of some active species Ce on the surface of TiO2, thus the optimal mass ratio of the composite carrier was of great importance.

One challenge of successful drug loading is to identify the appropriate mass ratio of drug to carrier, such that the nanoparticles can retain colloidal stability after drug loading, with minimal interparticle bridging [17].
At the lowest MNP loadings (GO/MNP mass ratio of 1/5), the majority of the primary magnetic nanocrystals are well-distinguishable and clustering only occurs on a few locations of the GO surface, for example, near the top right corner of the image.
Define the external/internal spring rigidity ratio as [alpha] = K/k, the shell/oscillator mass ratio as [beta] = M/m, and the linear natural frequency of oscillator as [[omega].sub.n] = [square root of 2k/m] by introducing dimensionless time [tau] = [omega]t and dimensionless nonlinear coefficient [bar.[GAMMA]] = [GAMMA]/m[[omega].sup.2.sub.n].
