Interface hybrid

A distinct characteristic of hybrid materials is that not only are their properties related to the chemical nature of the inorganic and organic components, but they also rely heavily on their synergy. Therefore, the interface between inorganic and organic domains is of paramount importance. Indeed, one key point is the control of this interface, the hybrid interface.

Fig. 4 Ligand assisted templating mechanism for the synthesis of niobium oxide. The amine surfactant forms covalent bonds with the niobium (V) ethoxide, resulting in the formation of a hybrid interface. Upon exposure to water, the system organizes into various structures such as bidimensional hexagonal (Nb-TMSl), three-dimensional hexagonal (Nb-TMS2), lamellar (Nb-TMS4), or a cubic phase. (Nb-TMS3 is not shown in the figure.) (From Ref...

The resultant hydrolyzed, polar species can have a better interaction with the polar head group of the surfactant, resulting in the formation of ordered structures. Soler-illia et al. reported a modulation of hybrid interface approach, which relies on the addition of controlled quantities of water to the solution of the inorganic precursor and a nonionic surfactant in an organic solvent to obtain ordered mesostructures.

Tlie involvement of the visual cortex in tactile discrimination of orientation was demonstrated experimentally, thus pointing to the necessity to take the wider concept of perceptions into account when developing advanced hybrid interfaces for prosthetics. 

A generalized cooperative mechanism of formation was proposed based on the specific electrostatic interactions between an inorganic precursor / and a surfactant head group S. The hybrid inorganic-surfactant mesophases obtained are strongly dependent on the interactions between the surfactants and the inorganic precursors (i.e. the hybrid interface).

The self-assembly concept also allows for the preparation of mixed lipid membranes that can offer a larger variety of lipid-based membranes with diverse functionalities that can be of interest in different technological applications [208]. These hybrid layers are composed of individual membrane leaflets of different molecules [209-211]. Such a hybrid interface has been assembled on sepiolite and was composed of an inner phosphatidylcholine mmiolayer (ML-PC)...

Composite materials are made by combining two or more materials to give a imique combination of properties. Many common materials are indeed composites, including wood, concrete, and metals alloys. However, fiber-reinforced composite materials differ from these common materials in that the constituent materials of the composite (eg the two or more phases) are macroscopically distinguishable and eventually mechanically separable. In other words, the constituent materials work together hut remain essentially in their original bulk form (apart from the thin hybrid interface between the phases).

So the sheer number of possible scenarios and hybrid composites is certainly overwhelming. Yet the same question as in the discussions in the preceding chapters applies here, too Is it possible to reveal generic features in adsorption processes and, in the same context, what can we learn about the specificity of hybrid interfaces ... 

The trade-off may be a model that consists of a combination of coarse-grained and atomic interactions. Such a model will not only be computationally feasible, it will also allow to treat essential specific properties of hybrid interfaces of proteins and solid...
