Abstract We investigated the origin of n-type thermoelectric properties in single-wall carbon nanotube (SWCNT) films with anionic surfactants via experimental analyses and first-principles calculations. Several types were employed to fabricate SWCNT drop-casting, followed by heat treatment at various temperatures. In particular, sodium dodecylbenzene sulfonate (SDBS) surfactant heated 350 °C ex...

This study presents the experimental results on dynamic contact angles of pure surfactants and surfactants with electrolyte solutions on PTFE (Teflon) surface. Dynamic advancing (theta(A)) and receding (theta(R)) contact angles measurements by the Wilhelmy plate technique were carried out for aqueous solution of three different surfactants Triton X-100 (TX-100), sodium dodecylbenzene sulfonate ...

The capability of image semantic segmentation may be deteriorated due to the noisy input image, where denoising prior help. Both and have been developed significantly with advance deep learning. In this work, we are interested in synergy between these two tasks by using a holistic model. We observe that not only helps combat drop accuracy input, but also pixel-wise information boosts denoising....

Considering the omnipresence of microplastics (MPs) in aquatic environments, they are expected to exert significatn impacts as carriers for diverse waterborne pollutants. In this work, adsorptive behavior two ionic components (i.e., sodium dodecyl benzene sulfonate (SDBS) and Cr(VI)) has been explored against types MPs model adsorbents, namely poly (ethylene terephthalate) (PET) polystyrene (PS...

Optical studies of single-walled carbon nanotubes (SWNTs) dispersed in aqueous surfactant suspensions have made significant progress since the discovery of their bright band-gap fluorescence in the near-infrared region [1]. In this article we report the systematic investigation of the effect of chemical purification and oxidation on the spectroscopic properties of SWNTs. The SWNTs samples we pr...

We present an analysis of the dispersion characteristics and thermal conductivity performance of copper-based nanofluids. The copper nanoparticles were prepared using a chemical reduction methodology in the presence of a stabilizing surfactant, oleic acid or cetyl trimethylammonium bromide (CTAB). Nanofluids were prepared using water as the base fluid with copper nanoparticle concentrations of ...

We report a combined shear small-angle neutron scattering (shear-SANS) and rheo-optical study of dilute aqueous suspensions of SWNT bundles dispersed using ionic surfactants. Both shear-SANS and flow birefringence reveal weak shear-induced alignment of SWNT bundles along the direction of flow. In terms of a nematic order parameter, the degree of alignment is found to increase with the shear rat...

Abstract Background Predatory flagellates and ciliates are two common bio-contaminants which frequently cause biomass losses in Chlorella mass culture. Efficient targeted ways required to control these contaminations cultivation aiming for biofuel production especially. Results Five surfactants were tested its ability bio-contaminations All five able eliminate the contaminants at a proper conce...
