  Confinement can modify the dynamics, the thermodynamics and the structural
properties of liquid water, the prototypical anomalous liquid. By considering a
general anomalous liquid, suitable for globular proteins, colloids or liquid
metals, we study by molecular dynamics simulations the effect of a solvophilic
structured and a solvophobic unstructured wall on the phases, the crystal
nucleation and the dynamics of the fluid. We find that at low temperatures the
large density of the solvophilic wall induces a high-density, high-energy
structure in the first layer ("tempting" effect). In turn, the first layer
induces a "molding" effect on the second layer determining a structure with
reduced energy and density, closer to the average density of the system. This
low-density, low-energy structure propagates further through the layers by
templating effect and can involve all the existing layers at the lowest
temperatures investigated. Therefore, although the high-density, high-energy
structure does not self-reproduce further than the first layer, the structured
wall can have a long-range effect thanks to a sequence of templating, molding
and templating effects through the layers. We find dynamical slowing down of
the solvent near the solvophilic wall but with largely heterogeneous dynamics
near the wall due to superdiffusive liquid veins within a frozen matrix of
solvent. Hence, the partial freezing of the first hydration layer does not
correspond necessarily to an effective reduction of the channel section in
terms of transport properties.
