Fig. 1From: Effect of Titanium Surface Calcium and Magnesium on Adhesive Activity of Epithelial-Like Cells and FibroblastsXPS spectra of DW, Ca, Mg and non-process (NP) groups. a Ca2p peaks are observed between 340 and 360 eV (Ca). b Mg1s peak is observed between 1,297 and 1,309 eV (Mg). c O1s peaks comprise two peaks, namely Ti–O (approximately 530 eV) and Ti–OH (approximately 532 eV). Note that hydrothermal treatment increased surface OH regardless of the presence of cations in the solution. Red, –OH group; green, Ti–O group; blue, total oxideBack to article page
