Fig. 4: Interaction between CPAM, BPyHs and soil.
From: Fabricating supramolecular pre-emergence herbicide CPAM-BPyHs for farming herbicide-resistant rice
The change of (A) specific surface areas or (B) zeta potential of soil treated with CPAM. Difference was analyzed using the two-tailed unpaired t-test. Data represent mean ± SD. n = 3 independent experiments. Snapshot of paraquat molecules absorbed on a negatively charged nano-sphere after 6 × 106 timesteps MD simulations in (C) soil-paraquat system and (D) soil-CPAM-paraquat system. The negatively charged nano-sphere, with a radius of 1 nm, was employed to simulate soil particles. Density profile of paraquat molecules along the nanoparticle (inset) for (E) soil-paraquat system or (F) soil-CPAM-paraquat system. For the inset, one forth paraquat molecules in the MD box are removed. Variation in the interaction energy between (G) paraquat and nano-sphere in soil-paraquat system, or (H) between paraquat and nano-sphere, CPAM and nano-sphere in soil-CPAM-paraquat system within MD simulation time. Source data are provided as a Source Data file.
