Programming Structural Symmetry and Emission in Low‐Dimensional Hybrid Perovskites via Time and Temperature

open access: yesAdvanced Science, EarlyView.
We demonstrate programmable structural symmetry and emission in benzylammonium‐based low‐dimensional hybrid perovskites. Continuous shaking transforms orthorhombic platelets into a lower‐symmetry monoclinic phase with broadband emission, whereas thermal activation drives the reverse pathways toward a higher‐symmetry configuration resembling the ...

Aberrant GRP78 Phase Transition Sustains Endothelial IRE1α Signaling and Drives Blood–Brain Barrier Failure in Cerebral Amyloid Angiopathy

open access: yesAdvanced Science, EarlyView.
Vascular Aβ40 corrupts GRP78 phase behavior in brain endothelial cells, sustaining IRE1α–TRAF2–JNK signaling and driving apoptosis, tight junction loss, and blood–brain barrier failure in cerebral amyloid angiopathy. Pharmacological IRE1α inhibition restores vascular integrity, reduces leakage, and improves functional outcomes, revealing a targetable ...

A review on the mechanism of high repetition rate pulse interference on the RF front-end of GNSS receivers

open access: yesFrontiers in Physics
With the rapid advancement of pulse technology, given the extraordinarily high repetition frequency of high-repetition pulse interference, with pulse widths typically ranging from a few nanoseconds to several hundred nanoseconds, it possesses ultra ...

YAP1‐Driven Pathogenic Fibro‐Adipogenic Progenitors Secrete IL‐6 and FGF21 to Mediate Muscle‐Bone Crosstalk and Promote Bone Loss

open access: yesAdvanced Science, EarlyView.
Fibro‐adipogenic progenitors (FAPs) in atrophic muscle undergo YAP1‐driven pathogenic activation, secreting IL‐6 and FGF21 as bone‐catabolic myokines that mediate muscle‐bone crosstalk and promote bone loss. Genetic or pharmacological targeting of this YAP1‐FAP‐myokine axis rescues skeletal deterioration, identifying FAP‐derived myokines as therapeutic

Photoelectric Imaging of the Optically Inactive Charge State of Silicon‐Vacancy Defects in Diamond

open access: yesAdvanced Science, EarlyView.
Although the doubly negative charge state of the SiV center in diamond is predicted to ionize only in the ultraviolet and is therefore considered optically inaccessible, we demonstrate visible‐range photoelectric imaging enabled by a previously unrecognized regime of laser‐assisted tunneling. ABSTRACT The investigation of optically active point defects

Engineering Morphological Anisotropy to Control the In Vivo Transport Dynamics, Clearance, and Biodistribution of Silica Nanocarriers

open access: yesAdvanced Science, EarlyView.
Morphological anisotropy directs the in vivo transport under physiological flow and clearance of silica nanocarriers. Increasing anisotropy reduces cellular uptake, suppresses hepatic and splenic sequestration, and prolongs systemic circulation by steering particles toward the central flow core.
