Numerical simulations of heat conduction. (a) Simulated three-dimensional temperature profile of a heated GNR-FND nanohybrid in water. The simulation was conducted with COMSOL based on a volume-equivalent sphere approximation for both FND and GNR with \(\sigma I = 7\mbox{ $\upmu$W}\). (b) Simulated distance dependence of the temperature rises along the symmetry axis (z-coordinate) of the heated GNR-FND nanohybrid with \(n = 1\). (c) Simulated distance dependence of the temperature rises along the symmetry axes of the heated GNR-FND nanohybrids with \(n = 1\mbox{-}10\) (bottom to top curves). Inset: Three-dimensional temperature profile of two GNR spheres anchored on the north and south poles of a FND sphere. Only a quarter of the temperature profile is shown. (d) Simulated temperature rises, \(\Delta T_{\mathrm{GNR}}\) and \(\Delta T_{\mathrm{FND}}\), and their ratios as a function of the number of GNRs attached to the FND.
