Piezoelectric Biomaterials for Bone Regeneration: Roadmap from Dipole to Osteogenesis

open access: yesAdvanced Science, EarlyView.
Piezoelectric biomaterials convert mechanical forces into electrical signals, offering novel strategies to restore and modulate bone microenvironments for tissue engineering. This review examines molecular dipole origins, spatial arrangements, and pseudo‐piezoelectric mechanisms and highlights dipole‐engineering techniques for osteogenesis regulation ...

Microphysiological Uremia Model Reveals Biophysical Potentiators of Vascular Dysfunction

open access: yesAdvanced Science, EarlyView.
A microfluidic platform of engineered blood vessels is developed to study the role of mechanical forces in immune cell adhesion and extravasation in uremic microenvironments. Elevated pressure increases monocyte activity, with ICAM‐1 as a key driver. Matrix density influences monocyte phenotypes, but the uremic environment consistently promoted a pro ...

Surface‐Engineered Cenospheres Encapsulating Phase Change Materials for Functional Cementitious Composites

open access: yesAdvanced Science, EarlyView.
The global energy demand drives the need for advanced energy‐efficient building solutions. While current polymeric‐shell microencapsulated PCMs show promise for thermal energy storage, their use in cementitious materials is challenged by poor shell strength and interfacial bonding. This study develops novel cement‐compatible microencapsulated PCM using
