Modeling cochlear micromechanics: hypotheses and models

Journal of Bio-X Research, 2019
Abstract. The cochlea plays an important role in the mammalian auditory system. Sound-induced cell motion in the cochlea is transformed into electrical signals that are then sent to primary auditory neurons. The most significant feature of the cochlea is the active and nonlinear amplification of faint sounds. This active process cannot be explained via

Ultrastrong TEMPO‐Oxidized Densified Bamboo via Interface Decoupling and Hierarchical Toughening

Advanced Science, EarlyView.
This study develops TEMPO‐oxidized densified bamboo that achieves ultrahigh strength and toughness by decoupling rigid hydrogen bonds into reversible van der Waals interactions. TEMPO oxidation reorganizes the cellulose hydrogen‐bonding network, facilitating energy dissipation via reversible interactions, thereby establishing a general strategy to ...
