Unified Phase‐Field Framework for Antiferroelectric, Ferroelectric and Dielectric Phases: Application to HZO Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
HfxZr1−xO2${\rm Hf}_x{\rm Zr}_{1-x}{\rm O}_2$ offers CMOS‐compatible nanoscale ferroelectricity yet suffers from a high Ec${\rm E}_c$ demanding large operating voltages. A unified phase‐field framework spanning AFE/FE/DE phases shows how FE grains soften neighboring AFE grains over λ$\lambda$ ≈$\approx$ 22–37 nm.

A 3D Human Neuron‐on‐Chip Platform to Monitor Neuronal Injury Responses

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents a novel 3D Neuron‐on‐Chip model that can maintain human PSC‐derived excitatory prefrontal cortex neurons in 3D hydrogels and can be used to monitor neuronal injury responses over time. Results show injury‐induced acute neuronal excitotoxicity, declining neuronal connectivity, and the activation of a neurodegenerative, SASP‐like ...

Microfluidic Nano‐Assembly of Red‐Blood‐Cell (RBC) Lipids and Components for Engineering Extracellular Vesicles

open access: yesAdvanced Healthcare Materials, EarlyView.
Engineered red blood cell‐derived extracellular vesicles (eRBCEVs) are synthesized via controlled microfluidic assembly from native RBC lipids, enabling tunable encapsulation of proteins, nucleic acids, nanoparticles, and viral vectors. The platform demonstrates reproducible nanoscale architecture, preserved membrane composition, and functional cargo ...

Flash Assembloids: A Rapid Biofabrication of a Platform for Modeling Early Glioblastoma Invasion at the Glioblastoma–Brain Organoid Interfaces

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents a bioengineered assembloid (ASM) system combining glioblastoma (GBM) cells in oxidized alginate (OA) microgels with dorsal organoids (DOs). This model simulates brain tumor‐host interactions, revealing enhanced GBM invasion, altered gene expression, and aggressive infiltration patterns, demonstrating ASM as a valuable platform for ...

Cellular Responses to Mechanical Cues Across Scales: From Fundamental Insights to Translational Potential

open access: yesAdvanced Healthcare Materials, EarlyView.
This review examines how cellular behavior is regulated by mechanical cues transmitted through soft biomaterials, from single‐cell mechanosensing to tissue‐level adaptation. It highlights why physiological relevance, rather than model complexity alone, is critical for translational mechanobiology and introduces a scoring framework linking material ...

Spontaneous Tracheal Rupture: a Case Report

Acta Chirurgica Belgica, 2004
We report the case of a spontaneous posterior tracheal wall rupture following a cough. A 67-year-old woman with a history of longstanding treatment with corticosteroids (8 years) for Giant Cell Arteritis had general anesthesia for cataract removal. Surgery and anesthesia were uneventful.

Spontaneous retropharyngeal emphysema: A case report

Nigerian Journal of Clinical Practice, 2017
Retropharyngeal emphysema is usually secondary to trauma, iatrogenic injury, and obstructive respiratory diseases. Without prompt and adequate treatment, severe complication such as airway compromise may occur. Spontaneous retropharyngeal emphysema, defined by the presence of free air in the retropharyngeal space without any precipitating cause, is a ...

Spontaneous retroperitoneal hemorrhage: A case report

Journal of Surgical Oncology, 1982
AbstractHemorrhage resulted in a large retroperitoneal mass in an adolescent male. Surgical exploration revealed only hematoma. Serum markers were useful in leading to the correct diagnosis. This presentation has not been previously reported in embryonal cell carcinoma.
