Mechanical metamaterials can be used to control wave propagation since they are flexibly adjustable. In this paper, a one-dimensional rotor-in-rotor metamaterial with internal rotor coupling is proposed. This metamaterial introduces a new connection between lattices into a rotor-in-rotor system...

With the development of nanofabrication and nanomaterials, electrokinetic nanofluidic energy conversion has been studied in nanometre-scale, even sub-1 nm channels, which can sieve organic molecules. However, achieving simultaneous nanofluidic energy conversion and organic molecular sieving...
