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 …

Mechanical metamaterials and phononic crystals enable localizing, focusing, and guiding of
elastic or acoustic waves in various ways. Here, we describe the physical mechanisms …

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

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 …

Abstract Additive manufacturing (AM)(= 3D printing) and rational design techniques have
enabled development of meta-biomaterials with unprecedented combinations of …

Within a time span of 15 years, acoustic metamaterials have emerged from academic
curiosity to become an active field driven by scientific discoveries and diverse application …

Architectural windows that smartly regulate indoor solar radiation by changing their optical
transmittance in response to thermostimuli are developed as a promising solution toward …
