Acoustic diodes
Abstract
research highlights proposed so far involve the use of phononic Twisting thread Intermolecular intrusions crystal filters. These devices need to be Science 343, 868–872 (2014) Nature Commun. 5, 3321 (2014) larger than the wavelength they filter, which Peptides that can disrupt or permeate cell limits their use for audio and low-frequency membranes have been exploited in various applications, in the wavelength range of a biomedical applications including gene few metres and above....
