  • Here, the authors present a dual-mode solid state thermal rectification effect using a heterogeneous irradiated-pristine polyethylene nanofiber junction as a nanoscale thermal diode, in which heat flow can be rectified in both directions by changing the working temperature.

  • Heat conduction in solids is known to be contributed by phonons and electrons. Here, authors observe enhanced and non-diffusive thermal conductance mediated by surface phonon polaritons in polar dielectric nanoribbon waveguides.

  • The wafer-scale electrochemical synthesis of arrays of rough silicon nanowires is reported, as is their substantially reduced thermal conductivity, which improves their potential for thermoelectric applications.

  • Calorimetrically measuring the heat of single cells is currently not possible due to the sensitivity of existing calorimeters. Here the authors present on-chip single cell calorimetry, with a sensitivity over ten-fold greater than the current gold-standard.

  • An approach to achieve and directly measure enhancement of the thermal emission in far-field is lacking. Here, a thermometry platform was devised to extract the thermal emissivity from anisotropic nanoribbons of polar dielectrics, allowing direct quantification of the emissivity from a single nanoscale object.
