Carbon nano tubes applications

Several studies have been dedicated to the application of amine-modified carbon nano tubes (CNTs) as solid sorbents for C02 separation [65-69]. Industrial grade CNTs have been functionalized with tetraethylenepentamine (TEPA) by Liu et al. [65], and the effects of amine loadings on the C02 uptake, heat of adsorption, and adsorbent regenerability were investi-... 

It has been pointed out however that further innovative steps are needed before single nano-tubes devices with adequate reproducibility can be made. A paper by Zhang et al. (2006) indicates parallel research lines intended to develop the various complementary aspects of nano-sciences and their applications. They observed that metallic and semi-conducting carbon nano-tubes generally coexist in as grown... 

The above analysis takes the synthesis methods, the performance affected by the dispersion of CNTs, enhanced physical properties and the latest applications of carbon nanotube/polyurethane composites described in literature reports as the reference point. In the interest of brevity, this is not a comprehensive review, however, it goes through numerous research reports and applications which have been learned and described in the recent years. Despite that, there are still many opportunities to synthesize new carbon nano-tube/polyurethane systems and to modify carbon nanotubes with new functional groups. The possibility of producing modern biomedical and shape memory materials in that way makes the challenge of the near future.

In this study, we developed and set up the DNA/RNA extraction method using carbon nano-tubes as vehicle to trap, isolate, and purify the DNA/RNA of the bacterial and vii pathogens from the clinical samples ready for the PCR and qPCR testing. The object of this study is to evaluate the potential applications of the novel carbon nano-tube in a modem diagnostic laboratory. 

The (semi)conductive properties of fullerene derivatives and carbon nanotubes have been a topics of intense recent interest. Unfortunately, at the time of writing it is still not possible to obtain well-defined samples of nano-tubes in sufficient amounts to carry out PR-TRMC measurements. Relatively pure, powder samples of C60 were however available in the mid-1990s and large, if short-lived, PR-TRMC transients could be observed. More recently attention has focused on the methyl ester of phenyl-C61-butyric acid (PCBM) which is a soluble C60 derivative that has found applications as the electron accepting component in hetero-junction materials for solar energy conversion. 

With the directed synthesis of individual species of carbon nanotubes remaining unfeasible in the foreseeable future, the available mixtures have to be separated for their components before any application requiring specific kinds of tubes. This task turned out rather complex, and a conclusive solution is still pending, but some partial successes have been achieved nevertheless. These at least allow for the enrichment of certain nano tubes. 

There has been a trend in recent years to move towards the electrostatic deposition of paints for exterior automotive applications. Reasons for this include improved paint transfer efficiency. Normally, plastic parts need to be painted with a conductive primer prior to the electrostatic painting of base and clear coats. One of the most recent developments in the area of external automotive applications is that of intrinsically conductive resins for electrostatic painting. Currently there are commercial applications for body panels that utilize PPE/PA that contains carbon black as the conductive component. In the USA, a mirror shell application uses PPE/PA where the conductivity is achieved through the incorporation of graphite nano-tubes. 

The discovery of fullerenes in 1985 (1) sparked the interest of researchers in novel crystalline forms of carbon. As a result, while hollow carbon filaments and nano-tube-like stractures had been reported many years before (2), the publications of lijima and Ichihasi (3, 4) and Bethune et al. (5), shortly after the development of fullerenes, generated an unprecedented wave of excitement and intense research in academic as well as industrial labs around the world. Nobel laureate Richard Smalley, co-discoverer of fullerenes, was a strong advocate of nanotube research and his endorsement strengthened the field. The results of such an extensive effort quickly demonstrated the unique properties of these carbon structures, as well as a cornucopia of potential applications in many fields of technology (6).
