Decorated Single- and Multi-Walled Carbon Nanotubes Aiming H2S Sensing

Verissimo C., Ding M., Abbaspourrad A., Star A., Moshkalev S., University of Campinas - UNICAMP, BR

Carbon nanotubes are suitable materials for gas sensing. To promote or improve sensitivity, as well selectivity, experimental procedures have been developed to modify CNTs by the attachment of metal and metal oxide nanoparticles on nanotube [...]

Synthesis of platelet carbon nanofibers by an injection CVD method and their applications in hydrogen storage

Wu H.C., Li Y.Y., National Chung Cheng University, TW

In this manuscript, there are some significant results summarized as follows: 1. The platelet graphite nanofiners (PGNFs)were continuously produced by a vertical chemical vapor deposition reactor. 2. A detailed study found that the sulfur concentration [...]

Platelet graphite nanofibers synthesized by the pyrolysis of poly(ethylene glycol)/hydrochloric acid mixture and nickel catalyst

Lin W-H, Li Y.Y., Lin W-H, National Chung Cheng University, TW

The synthesis of platelet graphite nanofibers (PGNFs) by the thermal decomposition of mixture contain poly(ethylene glycol) (PEG) and hydrochloric acid (HCl) at 700 oC using Ni as a catalyst.The PGNFs synthesized with mix HCl in [...]

Electrical Conductivity Control in SPNT Process

Nguyen K.C., Dinh H.P., Tran T.T., Saigon Hi Tech Park Research Laboratories (SHTP Labs), VN

Electrical conductivity in SPNT (Solid Phase Nano Tube) had been found strongly depends on baking process and baking temperature, chemistry of solid carbon source. First, in the SPNT process , the material and process control [...]

Introduction to Raman Spectroscopy as a Characterization Tool for Carbon Nanotubes, Graphene, and other Carbon Nanostructures

Wall M., Hodkiewicz J., Thermo Fisher Scientific, US

While there have been many publications produced in which Raman spectroscopy has been used to characterize various aspects of carbon nanostructures, there have been few works published which provide an overview of what the technique [...]

Scalable Single Walled Carbon Nanotube Separation: from Process to Product

Fogden S., Kim K.C., Ma C., McFarlane G., Linde Electronics, US

The extraordinary electronic and optical properties of single walled carbon nanotubes (SWNTs) are determined by their structure; SWNTs are1 either metallic or semiconducting depending on their diameter and chirality . Many valuable applications in, for [...]

Highly conductive nanotube-filled polymers with exceptional properties

Tiano T., Czerw R., Coffin R., Adams R., NanoTechLabs Inc., US

NanoTechLabs has developed new methods for preparation of highly conductive high-performance polymers. We use novel, scalable methods to incorporate high aspect ratio, low diameter, metallic multi-wall nanotubes (MWNT) into high performance engineering resins and plastics. [...]

Interfacial Shear Strengths of Carbon Nanotube Reinforced Polymer Composites

Wernik J.M., Ornwell-Mott B.J.C., Meguid S.A., University of Toronto, CA

This paper expands on the existing literature of CNT polymer interfaces and describes the development of a multiscale computational model used to investigate the interfacial properties of nonbonded CNT polymer systems. Specifically, in this work, [...]

Role of interlayer interaction in the mechanical properties of a multi- walled carbon nanotube and a single-walled carbon nanotube bundle

Talukdar K., Mitra A.K., National Institute of Technology, Durgapur, IN

Molecular dynamics simulation is performed on a SWCNT bundle made up of four (5, 5) SWCNTs and on an armchair MWCNT taking Brenner’s 2nd generation reactive empirical bond order potential. The interlayer interaction in the [...]

Carbon Nanotube Arrays with Tunable Wettability and Their Applications

Indrat Aria A., California Institute of Technology, US

A combination of UV/ozone treatment and vacuum-pyrolysis process that can be used for fine tuning the wetting properties of the CNTs is introduced. In contrast to the widely known wet-chemical methods the UV/ozone treatment is [...]
