DOI: 10.1063/1.5065557
Abstract: Adaptive elastic metamaterials are generally tunable but not switchable. Here, the word “switchable” means switching between different bandgap mechanisms, such as from the local resonance bandgaps to the Bragg scattering bandgaps and vice versa. In… read more here.

DOI: 10.1063/5.0152525
Abstract: We report a topology-transformable resonator with two distinct stable states, one kinematically determinate and endowed with nearly rigid-body motion at low-frequencies, and the other accompanied by a floppy pseudo zero-energy mode capable of showing low-frequency… read more here.

DOI: 10.1088/1361-6528/ac5288
Abstract: Based on the method of non-equilibrium Green’s function, we investigate the thermal transport and thermoelectric properties of graphenylene nanoribbons (GRNRs) with different width and chirality. The results show that the thermoelectric (TE) performance of GRNRs… read more here.
