摘要

There is now ample evidence for the existence of a crystalline organization of nanoscopic water layers at the interface of differently polar materials. Nanoscopic water layers were first observed in air. Surprisingly, they persist in subaquatic milieus, even under nonstationary conditions, e.g., at the interface between hydrophobic substrates and evaporating water drops known to be subject to massive convective flows, capable of driving micron-sized particles to the periphery of drops. The practical importance of organized water layers is enormous. They have been identified as transmitters of first-contact information in biosystems and are a key determinant for the design of advanced biomaterials. They play a central role in the transfer of charge between ice crystals and graupel pellets, and provide an explanation to the (otherwise unexplainable) capacity of hydrophobic aerosols to act as cloud condensation nuclei and ice crystal nucleators. However, direct observation of the organization of nanoscopic water layers is difficult. Therefore, progress in the field is slow. Their special importance for biosystems follows from the new understanding that ordered water layers potentially impose order to structures suspended in biological liquidsan active function and an extension of the older concept stating that order is imposed on the water layers by the substrates. Here we present a systematic method to indirectly analyze the nature of water layers. The results suggest that sessile drop evaporation models need reconsideration, even for simple liquids.
