  • The use of time modulation to break reciprocity is well understood for light, sound or charge diffusion, but it’s unclear whether it can work for thermal diffusion. Here, the authors answer in the negative by analysing diffusive processes under time modulation, and giving numerical and experimental evidence.

  • A thermal analogue of coherent perfect absorption would allow to control heat transfer using heat, but the lack of momentum propagation in a thermal field seems to prevent any role for coherence. Here, the authors allow this by introducing an imitated momentum for steady-state heat diffusion.

  • Transition metal dichalcogenides demonstrate fascinating capabilities for electrocatalytic H2 evolution, although the activities vary widely depending on nanomaterial sites available. Here, authors show the grain boundaries of atomically thin MoS2 to be especially active sites for H2 evolution.

  • The semiconductor–electrolyte interface dominates the behaviour of semiconductor electrocatalysts. Inspired by ion-controlled electronics a universal self-gating phenomenon is now proposed to explain transport modulation during electrocatalytic reaction.

  • Non-Hermitian systems can house a range of unusual physical phenomena such as the skin-effect which has been typically observed in optical lattices and electrical circuits. Here, the authors show the non-Hermitian skin effect in thermal transport, demonstrating that the topologically protected heat flow can be realized by using thermal metamaterials.
