Phase change materials (PCMs) can alleviate concerns over energy to some extent by
reversibly storing a tremendous amount of renewable and sustainable thermal energy …

Diffusion driven by temperature or concentration gradients is a fundamental mechanism of
energy and mass transport that inherently differs from wave propagation in both physical …

The description of phonon heat conduction has typically been based on Fourier diffusion
theory. However, over the past three decades, a host of interesting phonon transport …

Motivated by the synthesized Cu 4 Ti Se 4 with ultralow room-temperature thermal
conductivity [Angew. Chem., Int. Ed. 60, 9106 (2021)], we systematically investigate its …

The reduced dimensionality makes low-dimensional nanomaterials possessing diverse
unusual size-dependent transport properties, due to the distinct quantum confinement …

Phononic crystals (PnCs) control the transport of sound and heat similar to the control of
electric currents by semiconductors and metals or light by photonic crystals. Basic and …

Achieving nanocomposites with simultaneous highly anisotropic thermal and electrical
conductivities using carbon materials remains challenging as carbon material tends to form …

Electrochemical ion insertion involves coupled ion–electron transfer reactions, transport of
guest species and redox of the host. The hosts are typically anisotropic solids with 2D …
