“…The binding energy difference between the Ca 2p3/2 and Ti 2p3/2 peaks at 111.3 eV agrees with a difference of 111.2-111.3 eV for the calcium phosphates on TiO2 [4]. eV agrees with that previously reported for glucose, 1.5 eV [21]. The peak at 533.1 eV in the O 1s spectra that appeared along with the growth of the CC-O peak is assigned to the OH groups of the glucose.…”

Rutile titanium dioxide (TiO2) ( 110)-(1×1) surfaces prepared in ultrahigh vacuum (UHV) were removed from the UHV, immersed in Hank's buffered salt solution (HBSS), and then re-introduced to the UHV to be examined for an atomic-level study of the osteoconductivity of TiO2. X-ray photoelectron spectroscopy (XPS) showed the adsorption of phosphate ions and divalent Ca ions from the HBSS. The density of the phosphate ions increased with the immersion time for up to 1 min and remained constant with further immersion time up to 1 week. Unlike in the case of the phosphate ions, the density of the Ca ions decreased with the immersion time after reaching the maximum value at 1 min immersion. Consequently, calcium phosphate was not formed on the (1×1) surface in the 1-week immersion. Scanning tunneling microscopy revealed molecule-sized spots covering the surfaces immersed for 1 min and longer. On the basis of density analysis by XPS, the spots were hypothesized to represent phosphate ions. Phosphate ions on the (1×1) surface are unable to undergo arrangement needed to facilitate the epitaxial growth of the brushite.

“…41 A comparison of these peaks with that of the pure glucose shows them to be shifted at lower energy indicating the glucose moiety to be present in the Ag-γ-Fe 2 O 3 composite. 58 O1s spectrum shows four bands centered at 528.7, 529.8, 532.4 and 535 eV respectively. The intense band at 528.7 eV and a shoulder at 529.8 eV has been assigned to the lattice oxygen and anionic species 59 The coating of silver causes these chains to be broken and shows the particles to be smaller, more organized and isolated as is clearly indicated by their 3D images.…”

In this work we focus on P3HT:PC61BM bulk heterojunction (BHJ) devices with MoO3 at the hole extraction side of the BHJ, which relies on the formation of a strong dipole at the BHJ/MoO3 interface, as a reference system that has been extensively studied. We have observed, depending on when the annealing is performed during device fabrication, that the device performance either increased or decreased due to formation of a sharp or relatively diffuse interface, respectively, due to diffusion of MoO x into the BHJ. The measured strength of the dipole at this interface following thermal annealing correlated well with the width of the interface and device performance, with the sharper interface resulting in a stronger dipole and in improved device performance. This is expected to be a general phenomenon for evaporated coatings onto polymeric BHJ, regardless of the polymers involved.
