It has been recently investigated [A. Azizi and S. Ebrahimi, Nano 9, 1450088 (2004).] the Paclitaxel (PTX) anticancer drug molecule adsorption on nitrogen doped graphene (NG). However, the surface strain effect on adsorption is not considered in the literature. In this study, using molecular dynamics (MD) simulation, we show that the PTX molecule adsorption can be tuned by exploiting the rippling effect of the strained NG. The dependence of the nitrogen concentration in the presence of ripples on the surface, arising due to thermal fluctuations, is examined. We have also considered the connection between the average distance of PTX from NG surface and the maximum induced deformation on the surface structure. It is demonstrated that the average distance of PTX from NG is increased with increasing the strain until a critical value is reached, and then it has remained almost constant. To this end, the dependence of the degree of ripple-type distortion of the surface on the PTX adsorption is investigated.

The synergy between electrochemical oxidation and adsorption on particle electrodes was investigated in three-dimensional (3D) systems for p-nitrosodimethylaniline (RNO) decolorization and pesticide removal. A comparison was made between granular activated carbon (GAC) and a novel synthesized nitrogen-doped graphene-based particle electrode (NCPE). Experiments on RNO decolorization show that the synergy parameter of the 3D-NCPE system was improved 3000 times compared to the studied 3D-GAC system. This was due to the specific nanostructure and composition of the NCPE material. Nitrogen-doped graphene triggered an oxygen reduction reaction, producing hydrogen peroxide that simultaneously catalyzed on iron sites of the NCPEs to hydroxyl radicals following the electro-Fenton (EF) process. Data showed that in the experimental setup used for the study, the applied cell voltage required for the optimal value of the synergy parameter could be lowered to 5V in the 3D-NCPEs process, which is significantly better than the 15–20 V needed for synergy to be found in the 3D-GAC process. Compared to previous studies with 3D-GAC, the removal of pesticides 2,6 dichlorobenzamide (BAM), 2-methyl-4-chlorophenoxyaceticacid (MCPA), and methylchlorophenoxypropionic acid (MCPP) was also enhanced in the 3D-NCPE system.
