Figure Lengend Snippet: Figure 2. The X-ray diffraction (XRD) results for the depositions with different concentrations of (A) polyepoxysuccinic acid (PESA), (B) poly acrylic acid (PAA) at 30 ◦C, and 80 ◦C. c, a, and v represent calcite, aragonite, and vaterite, respectively.

Article Snippet: The water used in the experiment was 18.2 MΩ cm (HITECH, Medium-E400, Beijing, China) The patterns of the CaCO3 precipitations were recorded on a Bruker D8 Advance X-ray diffraction (XRD) instrument (Ettlingen, Germany), wherein the diffraction angle (2θ) was scanned in the range of 20◦–70◦.

Figure Lengend Snippet: Figure 6. The initial configurations and the optimized results of the two inhibitors on the surfaces of the calcite. For PAA, (a1,c1) represent the starting configurations on the (1 0 4) and (1 1 0) faces, respectively, while (a2,c2) are the optimized simulation results correspondingly; for PESA, (b1,d1) display the starting configurations on the investigated faces and the homologous optimal simulation results are shown in (b2,d2).
