Protein Structure from Scientific Research

The molecular surface electrostatic potential for the molecular structure of CDs at 325, 475, and 575 ℃ calcination conditions designed by HR-TEM images. The red region, blue region, and white region indicate the lower electron density, densely electron-dense region, and neutrality, respectively. The cyan, gray, red, and yellow spheres in the molecular structure represent carbon, hydrogen, oxygen, and silicon atoms, respectively. The ESP is electrostatic potential of the CDs.
