Among the many various methods of obtaining metal clusters and carbon/ metal containing nanostructures the synthesis in nanoreactors is considered the most perspective [3, 12], The main advantage of the above synthetic method in comparison with the others is the possibility to predict the result obtained depending on the matrix and nanoreactor selected, as well as the basic metal. However this method has not been sufficiently developed. For its development theoretical and experimental results are required. This paper discusses the ways for the production and investigation of nanoreactors in polymeric matrixes and synthesis of nanostructures with corresponding activity in them. Nanocomposites obtained in nanoreactors can be applied as modifiers of different compositions and materials.

The formation processes of metal-containing nanostructures in carbon or carbon-polymeric shells in nanoreactors can be related to one t) e of reaction series using the terminology of the theory of linear dependencies of free energies (LFE) [16]. Then it is useful to introduce definite critical values for the volume, surface energy of nanoreactor internal walls, as well as the temperature critical value. When the ration Ig k/k is proportional -AAF/RT, the ratio WAV can be transformed into the following expression ...

In this chapter, the degree of the modification depending on the eontent of carbon metal-containing nanostructures is studied for polymers such as polycarbonate, polymethylmethacrylate and polj inyl alcohol which have different structure and different content of oxygen bound to carbon.

The method for the modification of polymer with carbon metal-containing nanostructures includes the preparation of fine-dispersed suspension (FDS) based on the solution of polymer in methylene chloride. Then, earbon metal-containing nanostructures are added into the prepared FDS. For the refinement and uniform distribution of carbon metal-containing nanostructures, the prepared mixture is treated with ultrasound. To prepare a film, the solvent is evaporated from the mixture at heating to 100°C. 

To demonstrate the utilities of salt inclusion, we review the selected zeoUte-like transition-metal-containing open frameworks (TMCOFs) and then describe the structures of non-centrosymmetric solids (NCSs) and, finally, report crystalline solids containing a periodic array of transition metal nanostructures. In particular, we will address the issues concerning the role that molten salt has in... 

In order to achieve improved nanofabrication performance, novel functional block copolymer systems are strongly desired. Many researchers have recognized this, and novel functional systems such as metal-containing block copolymer systems have significantly simplified and improved nanofabrication processes. The combination of top-down microscale patterns with the bottom-up nanopatterns are attractive for integrating functional nanostructures into multipurpose on-chip devices. However, in order to use these materials in real-time applications, further development is still needed. More ground-shaking discoveries are needed and are also fully expected.

D nanoribbons and nanowires of different metal-containing Pcs have also been prepared by organic vapor-phase deposition (OVPD), a technique used to fabricate organic millimeter-sized crystals, thin films, or nanostructures [211], Scanning electron microscopy (SEM), TEM, x-ray diffraction (XRD), and absorption measurement studies have revealed that the morphology of the nanostructures was strongly dependent on the chemical nature of the deposited macrocycle, the nature and the temperature of the substrate, and the source-to-substrate distance. 

Development and application of composites containing nanostructured forms of metals open new horizons in creation of novel composite materials with controlled-quality properties and their usage in various kinds of human activity medicine, nanophotonics, catalytic chemical and refining processes, membrane technology, ecology, climate-monitoring systems, pure energetic, etc.

The keen interest in research of planar metal-containing nanostractures is due to peculiarities of its physico-chemical parameters compared with the corresponding parameters of bulk materials and, thus, due to great promise of these stractures for nanoelectronics and optics. Recently revealed high conductivity of Cu nanostructures at room temperature stimulated an interest in scattering measurements as an alternative nondestructive statistical method to study properties of these nanoobjects. Such investigations must precede the costly near-field optical microscopy. 

Pyrolysis of phase-separated PFS block co-polymer films also allows the formation of metal-rich nanostructures. For example, pyrolysis of a thin film of PS-/)-PFS with cylinders of the amorphous PFS block perpendicular to the substrate and in a cross-linked PS matrix at 600 °C yields iron oxide-containing dots on a substrate.
