Analysis and design of a cantilever-mounted resilient-pad gas-lubricated thrust bearing [PDF]

open access: yes
A thrust bearing consisting of pads mounted on resilient, metallic, cantilever beams is described and analyzed. Compliance and stiffness of the bearing assembly are discussed, and the effects of bearing design parameters on performance are shown.

Developmentally Inspired Bioprinting of Nascent Multicellular Human Heart Tissue Through in Situ Differentiation and Morphogenesis of iPSCs

open access: yesAdvanced Science, EarlyView.
A developmentally inspired bioprinting approach enables the fabrication of pluripotent tissues that undergo shape‐morphing and in situ cardiac lineage specification. This method employs embedded bioprinting to deposit iPSCs within soft granular hydrogels to create pluripotent tissue constructs that undergo cell‐mediated shape morphogenesis.

Size-scaling limits of impulsive elastic energy release from a resilin-like elastomer

open access: yes, 2018
Elastically-driven motion has been used as a strategy to achieve high speeds in small organisms and engineered micro-robotic devices. We examine the size-scaling relations determining the limit of elastic energy release from elastomer bands with ...

Dual‐Physical‐Field Nanocatalysis: Injectable Hydrogel Enables Piezo‐Photothermal Synergy for Breast Cancer Therapy

open access: yesAdvanced Science, EarlyView.
ABSTRACT Piezocatalytic therapy (PCT) harnesses mechanical energy to generate tumor‐lethal reactive oxygen species (ROS), but its efficacy is limited by rapid electron‐hole recombination and poor intratumoral retention. To overcome these limitations, we engineered heterostructured BiOCl@CuO nanosheets embedded in an injectable, conductive ...

Breaking the Toughness‐Stretchability Trade‐Off in Hydrogels with Dynamic Hydrogen Bonding

open access: yesAdvanced Science, EarlyView.
A novel nanocomposite hydrogel architecture overcomes the inherent conflict between toughness and stretchability by integrating uniformly dispersed aminopropyl‐hybrid‐phyllosilicate nanosheets within a polyacrylamide matrix. This design leverages a dynamic hydrogen‐bonding network to facilitate efficient energy dissipation and self‐recovery.

Multimodal Wearable Biosensing Meets Multidomain AI: A Pathway to Decentralized Healthcare

open access: yesAdvanced Science, EarlyView.
Multimodal biosensing meets multidomain AI. Wearable biosensors capture complementary biochemical and physiological signals, while cross‐device, population‐aware learning aligns noisy, heterogeneous streams. This Review distills key sensing modalities, fusion and calibration strategies, and privacy‐preserving deployment pathways that transform ...

Mechanoadaptation via Myosin Cytoplasmic Redistribution Protects Circulating Tumor Cells From Shear‐induced Death During Hematogenous Dissemination

open access: yesAdvanced Science, EarlyView.
This study investigates how CTCs survive varying shear stress during hematogenous metastasis. We uncover a self‐protection mechanism, by which non‐adherent CTCs adapt to high shearing milieu through accumulated cytoplasmic myosin‐mediated disruption of myosin‐actin binding, attenuating force transmission into chromatin to protect CTCs from shear ...
