Engineering Ultrastable Intrinsic Radicals: Graphene Quantum Dots With NIR‐II Emission for Dynamic Deep‐Tissue Bioimaging

Advanced Science, EarlyView.
Stable radicals are attractive for photonic and quantum information technologies but are often limited by instability. We stabilize intrinsic radicals in graphene quantum dots via 2D polymerization of perylene derivatives, where bilayer defect confinement suppresses quenching (100–500 K).

Targeting the CRYAB/β‐Catenin Axis with an MMP‐9‐Responsive Hydrogel Disrupts CTC Clusters to Suppress Progression of Hepatocellular Carcinoma after Radiofrequency Ablation

Advanced Science, EarlyView.
The graphical abstract illustrates that sublethal thermal stress after iRFA upregulates the chaperone CRYAB in residual HCC cells, which stabilizes β‐catenin and drives a dual pathological program, including EMT and N2‐TAN polarization, thereby leading to heterotypic CTC cluster formation. The MMP‐9‐responsive hydrogel (XB@Gel) delivers XAV‐939 and BMS‐

Influences of various space current systems on the geomagnetic field in near-Earth space

Earth and Planetary Physics, 2023
Ground and space-based observations of the geomagnetic field are usually a superposition of different sources from the Earth’s core, lithosphere, ocean, ionosphere, and magnetosphere, and also from field-aligned currents coupling the ionosphere and ...

Inhibition of MEKK3 Prevents Cerebral Cavernous Malformation Progression Via Restoring Endothelial Integrity and Restricting Microglial Activation

Advanced Science, EarlyView.
In this study, we demonstrate that aberrant MEKK3 signaling in endothelial cells and microglia drives the progression of cerebral cavernous malformations (CCMs). Furthermore, we identify DPDH as a potent small‐molecule MEKK3 inhibitor with substantial therapeutic potential for CCM treatment.

The effect of model errors in ensemble sequential assimilation of geomagnetic field

Earth and Planetary Physics, 2023
Earth’s magnetic field is generated in the fluid outer core through the dynamo process. Over the last decade, data assimilation has been used to retrieve the core dynamics and predict the evolution of the geomagnetic field.

A Co‐Self‐Assembled Monolayer With Enhanced Coverage and Defect Passivation for Efficient Inverted Perovskite Solar Cells

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study achieved a co‐self‐assembled monolayer (Co‐SAM) with more uniform coverage on nickel oxide substrates and enhanced passivation of buried interfaces by incorporating 4PABCz into Me‐4PACz. Perovskite solar cells fabricated with this Co‐SAM achieved an efficiency of 26.33% and exhibited enhanced stability. The combination of nickel oxide (NiOx)
