Abstract Jumping droplet thermal diodes (JDTDs) are promising candidates to achieve thermal rectification for next‐generation thermal control. However, most prior demonstrations of JDTDs have relied on monolayer‐coated copper‐based superhydroph

Thermal analogues to electrical transistors offer the potential for heat flow switching and amplification. Here, the authors demonstrate a macroscopic magnetic thermal transistor with applications in thermal control and thermal logic circuits.

Preserving the large power factor of carbon nanotubes is challenging, due to poor sample morphology and a lack of proper Fermi energy tuning. Here, the authors achieve a value of power factor of 14 ± 5 mW m−1 K−2 originating from the preserved c

Low thermal conductivities in nanomeshes have been attributed to both wave-like and particle-like behaviour of phonons. Here, the authors use periodicity-controlled silicon nanomeshes to show that the particle backscattering effect dominates for peri

We report on the latest properties of solution spun carbon nanotube fiber (CNTF) and discuss these results in the context of the field of CNTF, as well as the broader field of high-performance fibers. Using high aspect ratio, high purity carbon nanot

Theoretical considerations suggest that the strength of carbon nanotube (CNT) fibers be exceptional; however, their mechanical performance values are much lower than the theoretical values. To achieve macroscopic fibers with ultrahigh performance, we

Inorganic nanomaterials are often depicted as rigid structures whose shape is permanent. However, forces that are ordinarily considered weak can exert sufficient stress at the nanoscale to drive mechanical deformation. Here, we leverage van der Waals
