Artificial muscles are reported in which reduced graphene oxide (rGO) is trapped in the helical corridors of a carbon nanotube (CNT) yarn. When electrochemically driven in aqueous electrolytes, these coiled CNT/rGO yarn muscles can contract by 8.1%, which is over six times that of the previous results for CNT yarn muscles driven in an inorganic electrolyte (1.3%). They can contract to provide a final...
In this paper, a carbon-based through-silicon via (TSV) channel, which is composed of vertical carbon nanotube (CNT) TSV and horizontal multilayer graphene (MLG) global wire, is proposed and examined by using an electrothermal co-simulation program. This program is in-house developed based on finite element method (FEM). In particular, both anisotropies and temperature dependences of material parameters,...
Nanocarbon‐based thermocells involving aqueous potassium ferro/ferricyanide electrolyte are investigated as an alternative to conventional thermoelectrics for thermal energy harvesting. The dependencies of power output on thermocell parameters, such as cell orientation, electrode size, electrode spacing, electrolyte concentration and temperature, are examined to provide practical design elements and...
