Wetting of low-energy surfaces (polymers, hydrophobized glass) by the aqueous solutions of binary mixtures of nonionic (Triton X-100) and cationic (cetyltrimethylammonium bromide) surfactants at the molar fraction of cationic surfactant α = 0.2, 0.5, and 0.8 was studied in the wide concentration range. It was shown that the contact angles of mixed solutions at low-energy surfaces could be predicted on the basis of surface tension isotherms. Concentration ranges of wetting synergism were determined.

    We have performed density-functional theory calculations for LiTiO/LiTiO (LTO/Li-LTO) interfaces and made a detailed analysis of the local atomic and electronic structures. In the bulk regions of the supercell, the atomic and electronic structures are well reproduced to be similar to those of...
