The Interplay of Curvature, Geometry, and Topology Shapes Tissue Organisation in Epithelial Shells

open access: yesAdvanced Science, EarlyView.
Purely geometric 3D Voronoi models predict the organisation of epithelial shells. The interplay of curvature, geometry, and topology enriches the number of pentagons in shells with lower number of cells. Small MDCK cysts and Mouse embryos match the top polygonal configurations in a compactness‐based ranking derived from the Voronoi model. In conclusion,

High‐Throughput Screening for Accelerated Oxide Glass Discovery

open access: yesAdvanced Science, EarlyView.
A high‐throughput screening platform is presented that allows for accelerating laboratory glass synthesis by a factor of 102, using multicomponent stereolithographic printing. Automatic sample evaluation is achieved via Raman spectroscopy and similarity analysis without any sample preparation.

Representing measures for the disc algebra and for the ball algebra [PDF]

open access: yes, 1991
We consider the set of representing measures at 0 for the disc and the ball algebra. The structure of the extreme elements of these sets is investigated.

Solution‐Processed Multi‐Junction Optoelectronic Synapses for Mode‐Switchable SWIR Neuromorphic Vision Sensing

open access: yesAdvanced Science, EarlyView.
A novel bias‐programmable shortwave infrared (SWIR) vision sensor is developed using multi‐junction colloidal quantum dots (QDs). Under varying applied voltage, the back‐to‐back rectifying junctions effectively tune trapping centers to switch the device between high‐speed photodetector and persistent synapse modes.

SIRT7‐Mediated H2BK120 Succinylation Drives Aberrant Mitophagy in Sepsis‐Associated Cognitive Dysfunction

open access: yesAdvanced Science, EarlyView.
Sepsis triggers hippocampal SIRT7 loss, promoting histone H2B succinylation and activation of the PD‐1/PD‐L1–PINK1 axis. This metabolic‐epigenetic cascade drives aberrant mitophagy and neuronal injury, ultimately causing cognitive deficits. Targeting SIRT7‐dependent succinylation offers a potential strategy to protect brain function during sepsis ...

Static Drainage H2/O2 PEM Fuel Cells Enabled by Water Transport Plates: Pore‐Scale Design and Transport Mechanisms

open access: yesAdvanced Science, EarlyView.
The WTP is a key component of static drainage PEMFCs, enabling cathode water removal and gas sealing through capillary forces. This work investigates the mechanisms governing WTP drainage and sealing performance and develops predictive approaches for WTP design optimization.

Synergistic Regulation of Deep‐Cycling‐Induced Zn Pulverization and Resting Galvanic Corrosion in Practical Lean Zinc Anodes

open access: yesAdvanced Science, EarlyView.
Benzotriazole (BTA) regulates Zn reduction kinetics and suppresses galvanic corrosion, simultaneously mitigating Zn pulverization during cycling and self‐corrosion during storage, thereby enabling lean Zn anodes with enhanced cycling stability and extended calendar life.

Adaptive Network Stabilization Despite Profound Structural Reorganization in Human Organotypic Cultures

open access: yesAdvanced Science, EarlyView.
Adult human organotypic cortical slices undergo marked neuronal loss, laminar disruption, and glial activation, yet their network activity progressively stabilizes after a variable period. Electrophysiology, longitudinal calcium imaging, and quantitative histology show that structurally remodeled human circuits show adaptive capacity resulting in ...

Thickness‐Gradient Liquid Metal Connectors for Seamless Electrophysiological Sensors

open access: yesAdvanced Science, EarlyView.
Thickness‐gradient liquid metal interfaces with elastomeric substrates enable seamless integration between ultrathin skin‐conformal electrodes and external interconnects. The mechanically compliant connector reduces interfacial mismatch and supports stable ECG/EMG monitoring under bending and motion.

Asymmetric Structure‐Driven Functional Synergy: A Multistimuli‐Activated Janus Nanomotor for Self‐Amplifying NO Cascade Therapy

open access: yesAdvanced Science, EarlyView.
The Janus nanomotors leverage an “asymmetric structure‐driven functional synergy” strategy to orchestrate spatiotemporally coordinated catalytic functions, in situ self‐amplifying NO generation, and deep tumor penetration, thereby enabling controllable, sustained, and uniform NO generation within the tumor microenvironment.
