Abstract: Diffusion of volatile flammable species in the air can cause a fire risk within the nuclear reactor containment. However, computational prediction on species concentration distributions remains significantly difficult due ...

Abstract: 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 unit cells. This emerging class of ...

Abstract: Many biological materials have outstanding properties unparalleled by artificial materials because of their periodic and/or hierarchical structures. In this paper, the longitudinal elastic wave propagation in nacrelike ...
