Nano assemblers

Knowledge about protein folding and conformation in biological systems can be used to mimic the design of a desired nanostructure conformation from a particular MBB and to predict the ultimate conformation of the nanostructure [152]. Such biomimetic nano-assembly is generally performed step by step. This wiU allow observation of the effect of each new MBB on the nanostructure. As a result, it is possible to control accurate formation of the desired nanostmcture. Biomimetic controlled and directed assembly can be utilized to investigate molecular interactions, molecular modeling, and study of relationships between the composition of MBBs and the final conformation of the nanostmctures. Immobilization of molecules on a surface could facilitate such studies [153].

Nano-photosynthesis can produce sugar and starch for food and further synthesis of cellulose can produce paper and wood to avoid clear-cutting forests. Carbon retrieved from the atmosphere and recycled from existing wastes by MNT will be used to make carbon nano-tubes, with superior properties to steel. Carbon will be the most common structural and functional element for a MNT-based civilization [32,33]. A carbon-based MNT material production model is conceptualized as in Fig. 9. If there is a specific need for metal, a nano-factory with trillions of nano-assemblers will synthesize steel, copper, and alloys in order to skip mining and refining [32,33]. Therefore, industrial wastewater, hazardous wastes and air pollution will all vanish.

Evans et al. also showed that the 1 1 mixture of BAN and (3, y-distearoyl-phos-photidylcholine (DSPC) gives a smectic A texture in the temperature range of 57.3 to 100°C [21]. This is the first notice of lyotropic lamellar liquid crystals formed in the ionic medium. Additionally, Seddon et al. [28] and Neve et al. [29] have described the long-chained A-alkylpyridinium or l-methyl-3-alkylimidazolium ions to display smectic liquid-crystalline phases above their melting points, when Cl or tetrachloro-metal anions like CoCl " and CuCl " are used as the counter ions. Lin et al. have also noted the liquid crystal behavior of 1-alkylimidazolium salts and the effect on the stereoselectivity of Diels-Alder reactions [30]. However, liquid crystals are classified as ionic liquid crystals (ILCs), and they are distinguished from liquid crystals that are dispersed in ionic liquids. Although the formation of micelles and liquid crystal phases in ionic liquids have been thus reported, there has been no mention of the self-assembly of developed nano-assemblies that are stably dispersed in ionic liquids. In the next section the formation of bilayer membranes and vesicles in ionic liquids is discussed.

As shown in the table, most of the nanostructure-based nano assembled systems belong to this. A nano property element is the properties that are inherited, induced, or designed from nano assembly and its framework. Some of them could be the same properties as macroscale counterparts but in the nanoscale while others are those that emerge only when the systems have nanoscale features. A nano mechanical element is the unit operations... 

Figure 6.7 presents the general rules of nano assembly and their relationship with nanoelements. As a nano assembly becomes more desired (moving toward the right hand direction on the horizontal arrow of attrae-tive interaction-repulsive interaction balance), the nano element that will be expressed is a nano structural element. Typical nano pores, nanoparticles, nano crystals, nano emulsions, and nano composites are more likely to be obtained on this side of the arrow. On the other hand, if a nano assembly moves toward the left-hand side, it is more likely to obtain nano assembled systems that usually need an aid of external foree for their assembly. Colloidal erystal is one good example, especially when the size of nano assembly building unit (colloidal particle) is increased. Many top-down operation-based nanoelements are other examples. 

When a nano assembly is involved with a directional interaction, the most likely nano element will be a film or surface-based nanoscale operation. Examples include most of the nano-structured films regardless of their detailed morphology. Nano porous film, nano layered film, and nano patterned film are among them. It also includes most of the nanoscale products that are obtained as a result of directional growth (from the spherical-shape) such as nano rods, nano needles, and nanotubes. A good deal of... 

It is also important for many unique types of nano mechanical elements. By coupling with the external stimulus-specific nano assembly, the development of nanoelements on this side (right-hand side of both external stimulus-specific and chiral nano assemblies) can be much more fruitful. As far as the application for nanotechnology systems goes, the other side (left-hand side) of both diagonal arrows does not have mueh use in the development of specific nanoelements [52].
