Prospects for the Electrochemical Fabrication of Nanocompositions with HTSC Units... 

Plasma is effective in the fabrication of nanocomposites, such as nanoparticles composed of one material and covered by a nanolayer of another. Relevant examples include, in particular, carbon-coated magnetic metal particles produced in thermal arc plasma (McHenry et al., 1994), as well as polymer-coated nanoparticles with improved adhesion, corrosion resistance, and surface passivation produced in RF plasma in a fluidized bed (Shi et al.,... 

Yu et al. [112] reported the fabrication of nanocomposites of onedimensional (ID) titanate nanotubes and rutile nanocrystals by hydrothermal treatment of bulky rutile Ti02 powders. It was performed in a lOM NaOH solution without using any templates and catalysts. The iimer and outer diameters of the nanotubes were approximately 5 and 8 nm, respectively (Table 2). TEM and HRTEM images of the products revealed that many rutile nanocrystals of 5-10 nm attached to the outer surface of the titanate nanotubes. Some rutile nanocrystals of about 5 nm also existed in the interior of the nanotubes. This generates an interesting composite structure that possesses both the surface properties of rutile nanocrystals and the morphology and mechanical properties of titanate nanotubes.

The well-known nonequilibrium process of plasma chemical synthesis has found practical application for a large number of compounds and compositions. However, in recent years more attractive and well-developed processes of synthesis become gas phase condensation under quasi-equilibrium conditions of moderate heat and mass transfer. This process becomes preferable over latter plasma chemical synthesis due to its ability to control the thermal regime and more flexibility in regard to dispersion and purity of the synthesized product. Uniformity of particle size and chemical composition (powder purity) are essential for fabrication of nanocomposites or dense nanocrystalline materials with improved physical, chemical and mechanical properties. This is because the particle size distribution determines the stability of grains during consolidation of a polycrystal while the concentration of impurities affects properties of grain boundaries and entire material (Table 5.1). 

Nano-HAp was surface-treated with PMOEP in order to introduce phosphate-containing functional groups which were subsequently bonded to ethylene diamine-functionalised PLLA scaffolds or imbedded into PLLA scaffolds during fabrication. A grafting from approach made it possible to modify the surface of nano-HAp crystals. Thiol-functionalized HAp nanocrystals were used in the grafting polymerization of MOEP (unpurified). The results indicated that the PMOEP-grafted HAp nanocrystals exhibited increased colloidal stability in water. These modified nano-HAp particles were subsequently used for the fabrication of nanocomposite scaffolds. ... 

This review summarizes the recent achievements in preparation of various supermacroporous polymer cryogels via UV-induced crosslinking in partly frozen systems. The method is equally effective for the formation of cryogels from both water-soluble high molar mass linear polymers and vinyl monomers. Special attention is paid to some novel materials based on biodegradable and/or stimuli-respmisive polymers and their application in some emerging fields, as well as the fabrication of nanocomposites with intriguing properties. 

Another original approach for fabrication of nanocomposite aerogels based on CNTs and chemically cross-linked polymers was described by Zou, Liu, and Karakoti (2010). The authors first disperse MWNTs by poly(3-hexylthiophene)-b-poly(3-(trimethoxysilyl)propyl methacrylate) (P3HT-PTMSPMA) due to the n-n interaction between nanotubes and P3HT, form a physical gel and, then, cross-link the polymer layer by hydrolysis and condensation of PTMSPMA blocks (Figure 8.3). 

Design and fabrication of nanocomposites for musculoskeletal tissue regeneration... 

There are other nanocomposite materials apart from the ones mentioned in the previous sections. Table 1.1 fists a few examples of other nanocomposites employed in musculoskeletal tissue engineering. For example, carbon nanotubes have also gained a lot of interest in the fabrication of nanocomposites for musculoskeletal tissue engineering apphcations due to their unique mechanical and electrical properties (Harrison and Atala, 2007 Ahadian et al., 2014). Sitharaman et al. (2008) fabricated biodegradable...
