Cyclic Strain and Macrophage‐Mediated Transport Govern Micron‐Sized PM2.5 Translocation across the Air–Blood Barrier

open access: yesAdvanced Science, EarlyView.
Using a dynamic, tri‐culture air‐blood barrier model, this study reveals that macrophage‐mediated transport governs micron‐sized particle translocation under cyclic strain. The process is highly size‐dependent that 2 µm particles are transported by macrophages, 0.2 µm particles diffuse passively, and 5 µm particles are effectively blocked.

Patterns of recruitment and injury in a heterogeneous airway network model [PDF]

open access: yes, 2015
In respiratory distress, lung airways become flooded with liquid and may collapse due to surface-tension forces acting on air-liquid interfaces, inhibiting gas exchange.

A Super‐Capacitive Pressure Sensor with Ultrahigh Sensitivity and Wide Linear Pressure Sensing Range for Human Bio‐Signal Detection and Electronic Skin

open access: yesAdvanced Science, EarlyView.
Incorporating a PVA/H3PO4 ionic elastomer and a hierarchical hemisphere structure within the electrolyte layer, along with a curvy top electrode, enables the super‐capacitive pressure sensor to achieve ultrahigh sensitivity (34.79 nF kPa−1) and a broad linear sensing range (0–800 kPa).

Tidal dissipation in stars and giant planets

open access: yes, 2014
Astrophysical fluid bodies that orbit close to one another induce tidal distortions and flows that are subject to dissipative processes. The spin and orbital motions undergo a coupled evolution over astronomical timescales, which is relevant for many ...

Dual‐Function Piezo‐Photocatalytic Systems for Sustainable Hydrogen Evolution and Environmental Remediation

open access: yesAdvanced Science, EarlyView.
This article reviews dual‐function piezo‐photocatalytic systems that combine light and mechanical energy to produce hydrogen and clean the environment. It explains how various materials, including metal oxides, 2D structures, perovskites, and composites, enhance charge separation and reaction efficiency.

Kinematically Detected Halo Streams

open access: yes, 2016
Clues to the origins and evolution of our Galaxy can be found in the kinematics of stars around us. Remnants of accreted satellite galaxies produce over- densities in velocity-space, which can remain coherent for much longer than spatial over-densities ...

Structural Cement‐Based Supercapacitors with Multifunctional Robustness for Energy Storage

open access: yesAdvanced Science, EarlyView.
The breakthrough carbon cement supercapacitor features exceptional electrochemical performance and excellent robustness. The porous carbon cement electrode, characterized by high strength, extremely low resistance, is prepared by thermomechanical consolidation at 90 °C. Through in situ polymerization around sodium dodecyl sulfate‐mediated carbon black (
