During calcination the dissociation of the [Pt(NH3)4]2+ complexes in the [Pt(NH3)4](HC03)2 nano fibers starts at about 423 K with the removal of ammine ligands. Above 573 K the ammine ligands decompose to N2 and H2 [21]. The produced H2 induces the reduction of the Pt2+ ions and due to this autoreduction metallic Pt is formed even in oxygen atmosphere ...

POSS was mechanically dispersed in a functionalized polysiloxane gum using a speedimix (needs some details) and the mix cured using tin catalyzed condensation chemistry. Silica and Carbon nano fiber composites were produced by mixing the fiber into functionalized polysiloxane gum and the mix cured using tin catalyzed condensation chemistry. 

The SEM picture in Figure 7 shows a cut surface from a PDMS modified with silica nano fibers. The picture shows two fibres protruding from the surface and two holes resulting from fibres being pulled free from the material shown. Clearly this is indicative of a weak interface between the PDMS matrix and silica nano fibers. It should be noted that the production process for the silica nano fibre results in a significant amount of small particulate material. However, the stress strain response obtained from the PDMS systems formulated with the nano fibre shows some interesting trends.

At present a few studies of nanofibers and nanombes are focused on CNS drug delivery. One study evaluated electrospun nanofibers of a degradable polymer, PLGA, loaded with antiinflammatory agent, dexamethasone, for neural prosthetic applications (Abidian and Martin, 2005). A conducting polymer, poly(3,4-ethylenedioxythiophene), was deposited to the nano-fiber surface and the coated nanofibers were then mounted on the microfabricated neural microelectrodes, which were implanted into brain. The drug was released by electrical stimulation that induced a local dilation of the coat and increased permeability.

The composite displayed a strong mechanical resistance, neither formation of fine powder nor nanofiber loss being observed after sonication treatments (weight loss lower than lwt.%). This indicates the strong anchorage of the carbon nano fibers on the macroscopic graphite felt, which is required to resist the industrial conditions of use. 

Fluids containing suspensions of nanometer-sized solid particles are popularly known as nano-fluids. The solid nano-particles or nano-fibers size vary typically in the range of 1-100 nms. Nano-fluids have attracted great interest recently, particularly in... 

Fig. 9 Schematic representation of the hierarchal molecular assembly used to form a supramolecular hydrogel. The artificial glycolipid mimic GalNAc-suc-glu-lO-metyl-cyc-hexyl) forms incipient nano-fibers based on a bimolecular layer structure. Such fibers contain extensive hydrophobic domains in their cores with oriented saccharide arrays exposed at the interfaces. The incipient nano-fibers are bimdled to give thicker fibrils whose entangling results in the formation of a hydrogel...
