Nanostructure development

Due to a low solubility product of the phases formed, nanocrystals are easily formed, and it is difficult to avoid the nanostmctural features. The nanocrystal size is often in the range 10-40 nm with an open porosity with a nano-channel width in the range 1-3 nm [2, 9]. General properties of Ca-aluminate based biomaterials due to the nanostructures developed deal mainly with...

In summary, the area of non-lithographic techniques for nanostructuring of thin films and surfaces has been reviewed. It has been shown that these techniques provide cost-effective solutions for the realization of nanostructures like nanowires, nanodots, nanocones, nanopores, nanopillars. Apart from nanostructure development, non-lithographic techniques are unique, since they cause mass re-aystallization of the materials.

The engineering of novel deviees requires, in many eases, materials with finely seleeted and preestablished properties. In partieular, one of the most promising lines of synthetic materials research consists in the development of nanostructured systems (nanocomposites). This term describes materials with structures on typical length scale of 1-100 nm. Nanometric pieces of materials are in an intermediate position between the atom and the solid, displaying electronic, chemical and structural properties that are distinct from the bulk. The use of nanoparticles as a material component widens enormously the available attributes that can be realised in practice, which otherwise would be limited to bulk solid properties. 

The discovery of nanotubes and other nanostructures has opened up an exciting new field of research. But just what other shapes are possible and what other materials will form nanotubes To find out, we will need to predict the effect of different configurations. There are also many experimental problems to be solved. For example, how would you form an electrical connection to a nanotube Methods for synthesizing the large amounts of nanotubes needed in large-scale applications of nanotube assemblies also need to be developed. 

Section 7.3 will describe tools we developed to synthesize and characterize soft dendritic nanostructured TPE biomaterials via living carbocationic polymerization, and decorate their surfaces with tissue-friendly groups. 

Increasing price of crude oil has built up pressure on tire and automobile industry to develop low rolling-resistant tire with better traction. Combination of carbon and silica with coupling agent (dual filler technology) shows low RR with better traction and skid resistance in tire tread compound. Carbon black developed by plasma process and nanostructure black are other new significant developments in filler technology. 

The nanostructured molecular arrangements from DNA developed by Seeman may find applications as biological encapsulation and drug-delivery systems, as artificial multienzymes, or as scaffolds for the self-assembling nanoscale fabrication of technical elements. Moreover, DNA-protein conjugates may be anticipated as versatile building blocks in the fabrication of multifunctional supramolecular devices and also as highly functional-... 

Most published work on the design and fabrication of nanostructures from biological macromolecules relate to DNA and proteins the use of other biopolymers, such as cyclodextrins [2], was far less developed. Because the use of DNA is intensively covered in Chapter 10 of this volume (also see Ref 3), as well as recently described by Seeman [4,5] this chapter will focus on proteins as a potential tool for the construction of nanostructures. Hence this chapter is focused on literature that may provide a basis for the identification of gnidelines, methodologies, and examples having potential for farther development of new protein-based composite nanostrnctnres integrating strnctnral and bioactive components. 

Several attempts were made to apply nanostructures made of DNA or proteins to the development of alternative computation or computer memory. The concept of DNA computing was developed as an alternative computation approach based on information and data stored as sequenced DNA nucleotides and DNA-specific hybridization and elongation as a means to reach the answer or solution to a problem. Available tools of molecular biology were employed to identify and analyze the results [66-68]. This multistage computation is based on the assumption that solutions can be sought in parallel, thus compensating for the relatively slow processing time.
