ABSTRACTCarbon nanotubes (CNTs) possess superior mechanical, physical and chemical properties that make them ideal candidates for making sensors. However, challenges restricting their widespread applications in sensors still exist. To make the CNTs-based sensors own higher performance, nature has offered us with scientific and technological clues from the formation of biological composites using common organic components via naturally mild approaches. This paper reviews the recent progress on the bio-inspired synthesis of the CNTs-based sensors and their unique structures and novel properties.

Soon after the discovery of carbon nanotubes (CNTs) in the early 1990's, the B - and/or N -doped CNTs began to attract increasing interest owing to their modified structural, physical and chemical properties. In comparison with the multi-walled nanotubes and nanofibers, substitutional doping of the single-walled nanotubes (SWNTs) has proved to be much more difficult, and it is only in very recent years that some experimental studies concerning the B - and/or N -doped SWNTs are emerging. This paper intends to provide an up-to-date overview of current research on the doped SWNTs, with scopes covering both the binary system of CB x- and CN x-SWNTs and the ternary B x C y N z-SWNTs. A survey of the latest achievements in the syntheses of doped SWNTs through either the direct syntheses methods or the post-synthetic substitution reaction route is first presented; then the aspects concerning their structural features, elemental compositions, dopants bonding configuration and atomic distributions, as well as their physical and chemical properties are discussed.

AbstractThe interesting physical and chemical properties of carbon nanotubes (CNTs) have prompted the search for diverse inorganic nanotubes with different compositions to expand the number of available nanotechnology applications. Among these materials, crystalline inorganic nanotubes with well-defined structures and uniform sizes are suitable for understanding structure–activity relationships. However, their preparation comes with large synthetic challenges owing to their inherent complexity. Herein, we report the example of a crystalline nanotube array based on a supertetrahedral chalcogenide cluster, K3[K(Cu2Ge3Se9)(H2O)] (1). To the best of our knowledge, this nanotube array possesses the largest diameter of crystalline inorganic nanotubes reported to date and exhibits an excellent structure-dependent electric conductivity and an oriented photoconductive behavior. This work represents a significant breakthrough both in terms of the structure of cluster-based metal chalcogenides and in the conductivity of crystalline nanotube arrays (i.e., an enhancement of ~4 orders of magnitude).

Carbon nanotubes are structures where, due to their ideal structure, there is no electron scattering on defects in the crystal structure, so that they have high conductivity and low heat release during the passage of current. Thus, carbon nanotubes that conduct heat well are a material that can be used to achieve high thermal insulation properties. The exceptional physical and mechanical properties of carbon nanotubes make it possible to use them as nanofillers in order to obtain new materials with predictable properties and characteristics. Due to their structure and geometry, CNTS have unique mechanical, sorption and other properties. The unique structure of CNTS provides them with high surface activity, because of which they are widely used as fillers and functional additives. Modification of the material by nanotubes can lead to a significant improvement in the physical and mechanical characteristics of the original systems, as well as to an increase in their energy – saving properties. To date, the creation of composite materials based on carbon nanotubes is one of the most pressing issues, and the study of physical, chemical and mechanical characteristics of nanocomposites remains relevant, has scientific and practical significance, since the creation of such materials opens up great opportunities for their use in various fields of industry. In this work the influence of carbon nanotubes on some physical and chemical properties of GF-021 applied on various surfaces, such as brick, wood, gypsum board been, investigated. The results of the experiments show that the functional additive based on carbon nanotubes favorably influences such properties of the GF-021 primer as the drying time and stability to the static action of a 3 % solution of sodium chloride.
