Scaffold RNA Reengineering for a Leakage‐Suppressed CRISPR/Cas12a Cascade System Toward Precise Nucleic Acid Diagnostics

open access: yesAdvanced Science, EarlyView.
Schematic illustration of the CALCas system, in which a conformational switch in the 3' terminal DNA extension of scaffold RNA (3'D‐SR) drives cascade‐activatable Cas12a cleavage while suppressing leakage. ABSTRACT Amplification‐free CRISPR detection has attracted significant attention for its capacity to circumvent the intricacies of nucleic acid ...

Hydrogen Production from Ammonia Electrochemical Cracking

open access: yesAdvanced Science, EarlyView.
NH3 electrochemical cracking (e‐cracking) is a complementary technique to centralized thermal cracking for releasing H2 from NH3. In this article, we review recent advances in catalyst development for these cracking techniques and conduct a techno‐economic analysis (TEA) to evaluate the economic feasibility of e‐cracking.

Skyrmion Bubbles by Design in a Centrosymmetric Kagome Magnet

open access: yesAdvanced Science, EarlyView.
Chemical tuning of magnetocrystalline anisotropy in the centrosymmetric kagome magnet TmMn6Sn6 is shown to drive a spin reorientation transition via an intermediate magnetic fan state and to stabilize an emergent skyrmion bubble lattice. Four‐dimensional cryogenic Lorentz scanning transmission electron microscopy confirms the nanoscale texture ...

Precision Nanomedicine for Traumatic Neural Injury: Functional Paradigms and Translational Frameworks

open access: yesAdvanced Science, EarlyView.
This review presents a pathology‐driven framework unifying nanomedicine across TBI, SCI, and PNI. Epidemiological evidence and comparative single‐cell transcriptomic reanalysis define shared pathological modules, injury‐specific effectors, and therapeutic bottlenecks. Six functional paradigms connect nanomaterial structure and biological fate to injury‐

Decoupling Stable Cyclic Deformation From Defect Accumulation in Metals

open access: yesAdvanced Science, EarlyView.
Introducing amorphous nanoparticles into a metal matrix enables a cyclic deformation regime where strain hardening and defect accumulation are decoupled. These nanoparticles act as dislocation sinks and undergo reversible shear transformations, sustaining microstructural stability over millions of cycles.

Deciphering Electrochemical Generation, Transport, and Reactivity of Hydrogen Species in the Electrochemical Palladium Membrane Reactor

open access: yesAdvanced Science, EarlyView.
This study elucidates hydrogen transport and reaction mechanisms in ePMR using 1‐hexyne hydrogenation as a model reaction. Hydrogen transport operates via dual pathways involving hydrogen atom permeation and H2‐mediated re‐dissociation on secondary metal layers.
