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 …

Classical thermodynamics often helps to passively describe macroscopic heat phenomena
of natural systems, which means people almost cannot change the heat phenomena, but …

Simulated reality encompasses virtual, augmented, and mixed realities—each characterized
by different degrees of truthfulness in the visual perception:“all false,”“coexistence of true …

Conduction and convection are two fundamental methods of heat transfer, which are
generally considered independent. We manage to unify them by coining a complex thermal …

Existing thermal metamaterials are mostly designed to work at room temperature, where
thermal conduction is the dominant method of heat transfer. Unfortunately, as the …

Intelligent metamaterials have aroused intensive research interest due to their adaptive
responses to environmental changes. However, existing transformation-thermotics-based …

Almost all thermal metamaterials are essentially achieved by tailoring asymmetric interaction
between matrices and embedded particles. However, the asymmetric interaction results in …

The concentrating efficiency of a thermal concentrator can be reflected in the ratio of its
interior to exterior temperature gradients, which, however, has an upper limit in existing …

Compared with conventional topological insulator that carries topological state at its
boundaries, the higher-order topological insulator exhibits lower-dimensional gapless …

Janus metamaterials, metasurfaces, and monolayers have received intensive attention in
nanophotonics and 2D materials. Their core concept is to introduce asymmetry along the …
