Additive-free carbon nanotube dispersions, pastes, gels, and doughs in cresols [Engineering]

29-May-2018 | Kevin Chiou; Segi Byun; Jaemyung Kim; Jiaxing Huang, Proceedings of the National Academy of Sciences current issue, 2018

Carbon nanotubes can now be produced in the ton scale in the form of powders, but they need to be further processed, usually by solution-based routes, into disaggregated and more usable forms for applications. There has been extensive effort to search and design solvents that can disperse ...

PEG-nanotube liquid crystals as templates for construction of surfactant-free gold nanorods

28-May-2018 | Naohiro Kameta; Hidenobu Shiroishi, Chemical Communication, 2018

Lyotropic liquid crystals, in which nanotubes coated with polyethylene glycol were aligned side-by-side in aqueous dispersions, acted as templates for the construction of surfactant-free gold nanorods with controllable diameters, functionalizable surfaces, and tunable optical properties.

Self-templated fabrication of FeMnO3 nanoparticle-filled polypyrrole nanotubes for peroxidase mimicking with a synergistic effect and their sensitive colorimetric detection of glutathione

27-May-2018 | Maoqiang Chi; Sihui Chen; Mengxiao Zhong; Ce Wang; Xiaofeng Lu, Chemical Communication, 2018

A self-templated approach has been developed for the preparation of FeMnO3 nanoparticles filled in the hollow core of polypyrrole (PPy) nanotubes by an in situ polymerization process accompanied by the etching of FeMnO3 nanofibers. The prepared FeMnO3@PPy nanotubes exhibited a superior ...

Modelling of adsorption and intercalation of hydrogen on/into tungsten disulphide multilayers and multiwall nanotubes

27-May-2018 | José I. Martínez; Alex Laikhtman; Hoi Ri Moon; Alla Zak; Julio A. Alonso, Physical Chemistry Chemical Physics, 2018

Understanding the interaction of hydrogen with layered materials is crucial in the fields of sensors, catalysis, fuel cells and hydrogen storage, among others. Density functional theory, improved by the introduction of van der Waals dispersion forces, provides an efficient and practical workbench ...

Evidence for the electrochemical production of persulfate at TiO2 nanotubes decorated with PbO2

26-May-2018 | José Eudes L. Santos; Marco Antonio Quiroz; Monica Cerro-Lopez; Dayanne Chianca de Moura; Carlos A. Martín ..., New Journal of Chemistry, 2018

It is well known that PbO2-based electrodes are considered to be non-active anodes, producing higher concentrations of hydroxyl radicals in aqueous solutions, and consequently, favouring the electrochemical degradation of organic pollutants. However, no evidence has been reported on the ...

Patterned polyaniline encapsulated in titania nanotubes for electrochromism

26-May-2018 | Haiming Lv; Yi Wang; Lei Pan; Leipeng Zhang; Hangchuan Zhang; Lei Shang; Huiying Qu; Na Li; Jiupeng Zhao; Yao Li, Physical Chemistry Chemical Physics, 2018

In this article, we report the preparation of a TiO2 nanotube array (TNA) film used as a transparent electrochromic material and a TNA/polyaniline patterned hybrid electrochromic film utilized as an information display material. The TNA film was fabricated by an anodizing process, and a surface ...

Halloysite nanotubes sandwiched between chitosan layers: a novel bionanocomposite with multilayer structure.

25-May-2018 | Vanessa Bertolino; Giuseppe Cavallaro; Giuseppe Lazzara; Stefana Milioto; Filippo Parisi, New Journal of Chemistry, 2018

This work is a contribution to the design of multilayer biocomposites based on halloysite nanotubes (HNTs) and chitosan. Both the polymer and nanotubular inorganic additive have been selected among easily available green materials. An innovative preparation procedure based on the sequential ...

Origin of enhancement in Raman scattering from Ag-dressed carbon-nanotube antennas: experiment and modelling

23-May-2018 | T. V. Raziman; J. A. Duenas; W. I. Milne; O. J. F. Martin; P. Dawson, Physical Chemistry Chemical Physics, 2018

The D- and G-band Raman signals from random arrays of vertically aligned, multi-walled carbon nanotubes are significantly enhanced (up to ∼14×) while the signal from the underlying Si substrate is simultaneously attenuated (up to ∼6×) when the nanotubes are dressed, either capped or coated, with ...
