Diffusion and wave propagation are both fundamental transport mechanisms, but they have
intrinsically different dynamics, governing equations, and applications. Over the past …

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 concept of metamaterials originates from the proposal of left-hand materials with
negative refractive index, followed by which, varieties of metamaterials with kinds of fantastic …

We demonstrate the emergence of a pronounced thermal transport in the recently
discovered class of magnetic materials—altermagnets. From symmetry arguments and first …

Phononic crystals (PCs) and metamaterials (MMs) can exhibit abnormal properties, even far
beyond those found in nature, through artificial design of the topology or ordered structure of …

Projection micro stereolithography (PμSL) is a high-resolution (up to 0.6 μm) 3D printing
technology based on area projection triggered photopolymerization, and capable of …

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

Thermal metamaterials have exhibited great potential on manipulating, controlling and
processing the flow of heat, and enabled many promising thermal metadevices, including …

The concept of topological energy bands and their manifestations have been demonstrated
in condensed matter systems as a fantastic paradigm toward unprecedented physical …

Acoustic metamaterials can manipulate and control sound waves in ways that are not
possible in conventional materials. Metamaterials with zero, or even negative, refractive …
