“…16,17,30 In this work, the TEC properties were tested using a cup-shaped TEC and 0.4 M potassium ferro-ferricyanide aqueous solution was employed as the redox couple due to its high Seebeck coefficient. 2,7 As shown in Fig. 3a, the Seebeck coefficient was found to be $1.42 mV K À1 by linear tting of the data, which is in agreement with the previous reports.…”

“…Romano et al reported that the TEC performances of single-walled carbon nanotube-reduced graphene oxide hybrid electrodes were improved signicantly due to an enhanced mass transport property. 7 Im et al reported that decorating CNTs with Pt nanoparticles (NPs) could result in much higher conversation efficiency in comparison with pristine CNTs due to faster kinetics and larger electroactive sites.…”

Hybrid electrodes exhibit intriguing properties due to the synergetic effect of different components that are propitious for the practical applications of thermo-cells (TECs). In this study, Ag-carbon nanotube (CNT) hybrid electrodes were prepared using two simple and effective steps, involving the direct growth of CNTs on stainless steel substrates without any external catalyst, followed by decorating the CNTs with Ag nanoparticles. Ag-CNT electrodes were characterized via scanning electron microscopy, X-ray diffraction, Raman spectroscopy, and X-ray photoelectron spectroscopy and were applied in TECs for the first time. The TEC performances of the Ag-CNT electrodes were significantly enhanced compared to that of the pristine CNT electrode due to their better conductivity and thermal conductivity, as well as more activation sites. The results show that the construction of Ag-CNT hybrid electrodes can effectively improve the TEC performances of CNT electrodes, which is promising for heat energy harvesting by CNT-based electrodes.

“…Therefore, they were considered for the liquid phase exfoliation of graphite to graphene in the current study. In addition, cyclohexyl-pyrrolidone (CHP), which was found to be the most efficient solvent for the debundling of single walled carbon nanotubes (SWNTs) (surface tension of 38.8 mJ/m2) [62,63] was also considered for the solvent exfoliation process. Figure 1b shows EG dispersions in CHP, DMF and NMP after 8 h bath sonication.…”

The development of electrically conducting fibers based on known cytocompatible materials is of interest to those engaged in tissue regeneration using electrical stimulation. Herein, it is demonstrated that with the aid of rheological insights, optimized formulations of graphene containing spinnable poly(lactic-co-glycolic acid) (PLGA) dopes can be made possible. This helps extend the general understanding of the mechanics involved in order to deliberately translate the intrinsic superior electrical and mechanical properties of solutionprocessed graphene into the design process and practical fiber architectural engineering. The as-produced fibers are found to exhibit excellent electrical conductivity and electrochemical performance, good mechanical properties, and cellular affinity. At the highest loading of graphene (24.3 wt%), the conductivity of as-prepared fibers is as high as 150 S m-1 (more than two orders of magnitude higher than the highest conductivity achieved for any type of nanocarbon-PLGA composite fibers) reported previously. Moreover, the Young's modulus and tensile strength of the base fiber are enhanced 647-and 59-folds, respectively, through addition of graphene.
