Bioinspired Engineering of Streamlined Skeletal Interoception: Neural Bioprinted Piezoelectric Scaffolds for Neuro‐Vascularized Bone Regeneration

open access: yesAdvanced Science, EarlyView.
This study develops neural bioprinted piezoelectric scaffolds which construct local “sensor‐effector” circuit, inspired by the skeletal interoception system. Upon US stimulation sensing and mechanoelectrical coupling by PLLA nanofibers, the incorporated DRG neurons effect through Ca2+ influx‐induced enhanced secretion and expression of CGRP.

The Effect of Failure Criteria on Liquefaction and Pore Pressure Prediction in Non-Plastic Soils

open access: yesGeotechnics
Since the 1960s, cyclic triaxial tests have been utilized to assess the liquefaction susceptibility of cohesionless soils. While standardized procedures exist for conducting cyclic triaxial tests, there remains no universally accepted criterion for ...

Light‑Driven Propulsion of Graphene Aerogels in Microgravity

open access: yesAdvanced Science, EarlyView.
Ultralight graphene aerogels convert laser light into thrust. Parabolic‐flight experiments directly compare their motion in microgravity and at 1 g, revealing order‐of‐magnitude enhancements in distance, velocity, and transient thrust when weight and friction are removed (∼50 times enhancement).

Experimental study on deformation behaviors of saturated soft clay under intermittent cyclic loading with various drained conditions

open access: yesYantu gongcheng xuebao
In the previous studies, the cyclic triaxial tests under intermittent cyclic loading are used to study the deformation characteristics of soft clay under traffic loads. Both confining pressure and deviator stress vary cyclically in the stress field under
