A Hybrid Diffusion Model Enhances Multiparametric 3D Photoacoustic Computed Tomography

open access: yesAdvanced Science, EarlyView.
The hybrid diffusion PACT (HD‐PACT) system enhances dynamic multiparametric information using only 128–256 ultrasound elements. By overcoming limited‐view artifacts, HD‐PACT refines structural and functional information such as oxygen saturation observed in 3D premium PACT with > 1000 elements. Through cost‐effective and faster multiparametric imaging,

Electrosensitive Heterogeneous Short Fibers via Acousto‐Electric Coupling for Sequential Bone Regeneration in Infectious Defects

open access: yesAdvanced Science, EarlyView.
Electrosensitive heterogeneous short fibers can accurately respond to ultrasonic field regulation through the synergistic interaction of piezoelectric and conductive dual elements. At an ultrasound intensity of 1.5 W cm−2, it can effectively activate bacterial peroxisome and necrotic apoptotic pathway and promote bacterial apoptosis.
