3D organization

Usually, the zeolite inner surface characteristics are rather complex as a consequence of the (3D) character of the porous topologies of most of the zeolite types. The porous framework is a (3D) organization of cavities connected by channels. Inner surfaces are composed of several sorption sites characterized by their local geometry and curvature. Illustrative examples of such inner surface complexity are represented on Figures 1 and 2 they concern the Faujasite and Silicalite-I inner surfaces respectively. 

Three-dimensional (3D) conjugated systems do not exist but one can conceive 3D organic semiconductors comparable to the inorganic ones (Ge, GaAs). There, besides contributions from points Eg and lines Ej, will also contain contributions from critical sur-...

D organization of metal nanoparticles is easy to be reached compared with 2D or even ID, since nature tends to organize itself three-, but not two- or one-dimensionally. The most convenient way to get 3D assemblies of metal nanoparticles is to let them crystallize. Usually crystallization happens with identical molecules or with oppositely charged ions. Surprisingly, nanoparticles can form 3D crystals even if they are not identical in size and shape however, it is obvious that deviations should be as small as possible. 

Compared with 3D organizations and with some respect also with ID arrangements, ordered monolayers (2D) earn by far most interest owing to their potential applicability in future storage systems based on nanoparticulated building... 

We return to the self-trappping (ST) of Frenkel excitons in 3D organic structures. As a result of the Franck-Condon principle, photo-exciting a crystal from its ground state, with a regular lattice, leads to the initial creation of a coherent... 

In microcrystalline or amorphous materials, EXAFS has proved its usefulness since a long time. Limits and weaknesses of the technique have also been put forward variation of the EXAFS signal with temperature, occurrence of multiple scattering or destructive interference effects which complicate the extraction of the information. Sect. 2.2 presents how it is possible to overcome these apparent drawbacks and to obtain from them more information about the coordination site, its possible distortion and even about 3D organization of the material. 

As the knowledge of CuC O structure is necessary to explain its magnetic properties, an EXAFS analysis of this compound was undertaken in order to settle the correct model, since it is typically the kind of problem that EXAFS can solve in 3D organized compounds. 

Microfluidic Devices in Tissue Engineering, Fig. 6 Microfluidic channels in many ways resemble the vascular network In our body. Microfluidic networks made out of degradable materials like PLGA can be used to provide a structural backbone for seeding and culture of endothelial cells with perfusion and further construction of complex 3D organ and tissue architectures. Shown are the microfluidic network and endothelial cells seeded within the network [13]...
