To realize AlGaN-based solar-blind ultraviolet distributed Bragg reflectors (DBRs), a novel tri-layer AlGaN/AlInN/AlInGaN periodical structure that differs from the traditional periodically alternating layers of high- and low-refractive-index materials was proposed and grown on an Al0.5Ga0.5N template via metal-organic chemical vapour deposition. Because of the intentional design of the AlInGaN...
Tympanic membrane (TM) is vulnerable to a variety of middle ear diseases. In some cases, reconstruction or repair the TM essential for recovering hearing. Although there are many kinds materials and therapeutics reconstruction, tissue engineering still in its initial steps advancement. Treatment damaged usually carried out by otology-related techniques such as myringoplasty tympanoplasty. Most ...
While the mechanical behaviors of the fibrosa and ventricularis layers of the aortic valve (AV) leaflet are understood, little information exists on their mechanical interactions mediated by the GAG-rich central spongiosa layer. Parametric simulations of the interlayer interactions of the AV leaflets in flexure utilized a tri-layered finite element (FE) model of circumferentially oriented tissu...
