  bibo_abstract:
  - We study the variation of the adhesion forces between wet TiO2 nanoparticles as
    a function of their size and the ambient relative humidity. Combining all-atom
    molecular dynamics and capillary simulations we demonstrate that the linear scaling
    of the interparticle forces with the particle diameter, well established for microscopic
    and macroscopic particles, can be extended down to diameters of a few nm. At this
    size scale, however, the molecular nature of the water adsorbates dictates the
    adhesion forces both via solvation effects and influencing parameters of analytical
    capillary models such as the equilibrium particle–particle separation distance
    and the water/particle contact angle. Moreover, the water surface tension becomes
    considerably larger than the macroscopic bulk value due to combined effects of
    thin-film confinement and tight curvature, in a way that strongly depends on humidity
    and particle size. Taking these effects into proper account, classical capillary
    equations can be used to predict the interparticle forces even of the smallest
    particles considered here (4 nm), although the circular approximation fails to
    reproduce the distance at which the water meniscus breaks. Finally, the transition
    between the dominating effects at the nanoscopic scale and conventional capillary
    theory valid at microscopic size scales can be only rationalized if the presence
    of roughness asperities on the surface of the large particles is explicitly taken
    into account.@eng
