Chemically Driven Nano‐Elastic Heterogeneities Control Fragility in Volcanic Melts

open access: yesAdvanced Science, EarlyView.
The study elucidates how nanoscale structural heterogeneity governs the mechanical behavior of volcanic glasses across compositions from basalt to rhyolite. Using a physicochemical framework, correlation length (ξ) and microscopic free volume (Vc) are derived from vibrational and physical properties, revealing systematic trends with silica content that

Explicit Compression Degradation Estimations for Low‐Sampling Single‐Pixel Imaging using Hadamard Basis

open access: yesAdvanced Science, EarlyView.
This study proposes a degradation estimation technique to explicitly describe compressive sampling for low‐sampling Hadamard single‐pixel imaging. Blur kernels in explicit degradation models are estimated by the self‐supervised learning method without labeled data and implicit priors.

Aligned Nanostructures Resolve Zn2+ Transport Bottlenecks via Interfacial Kinetics–Diffusion Coupling in Aqueous Zinc‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
It is revealed that limited solid‐state Zn2⁺ diffusion within the cathode leads to interfacial Zn2⁺ accumulation, forming a transport bottleneck that distorts Zn2⁺ flux directionality. Through advanced analytical techniques, including in situ electrochemical impedance spectroscopy (EIS), distribution of relaxation time (DRT) analysis, and COMSOL ...

Dynamic Modulation of OECT‐Based Inverters for In Situ Electrophysiological Monitoring

open access: yesAdvanced Science, EarlyView.
This work presents a dynamic gain modulation system for inverter‐based in situ electrophysiological monitoring, enabling long‐term stable signal amplification via real‐time driving voltage adjustment. Moreover, stretchable complementary circuits (inverters, NAND, and NOR gates) are achieved based on a flexible PET substrate and a hexagonal network ...

Hundred‐Nanometer‐Thick Stretchable Liquid Metal Films for Ultra‐Conformal Bioelectrodes

open access: yesAdvanced Science, EarlyView.
A low‐temperature deposition strategy is proposed to fabricate 19 nm‐thick liquid metal nanofilms (conductivity: 3 × 10⁶ S m−1) for developing ultra‐thin, high‐conductivity epidermal electrodes. The 1 µm‐thick composite achieves 8.5 kΩ skin contact impedance and 26 dB EMG SNR, enabling robust dynamic electromyography during movement.

Marginal Stability of the YB1 Cold‐Shock Domain in Cells Enables Binding of Multiple Nucleic Acids

open access: yesAdvanced Science, EarlyView.
This study suggests that the marginal stability of the YB1 Cold‐Shock Domain (CSDex) allows for a balance between multifunctionality and conformational changes under physiological conditions. This balance is driven by the dynamic equilibrium between the unfolded ensemble (UE) and the native ensemble (NE) of CSDex (PDB:6LMR).

A Dynamic Gate Enables Regioselective Hydroxylation of Free Arginine by a Non‐Canonical Heme Enzyme

open access: yesAdvanced Science, EarlyView.
The YqcI/YcgG enzyme AglA employs a unique “sandwich” fold and a dynamic gating mechanism to selectively hydroxylate AMPn‐Arg at Nε. Site‐directed mutations reprogram regioselectivity or enable activity on free arginine by altering hydrogen‐bond networks, precisely positioning substrates.

Optimizing Surface *H Coverage over Cu2O/Co3O4 Heterojunction Enables Efficient Neutral Electrocatalytic Hydrogenation of 5‐hydroxymethylfurfural to 2,5‐dihydroxymethylfuran

open access: yesAdvanced Science, EarlyView.
This work presents a heterojunction strategy, wherein Co3O4 functions as a redox‐active cocatalyst to stabilize Cu⁺ sites and finely tune the electronic structure of Cu2O. Such interfacial modulation accelerates H2O dissociation kinetics under neutral conditions and enables optimal surface *H coverage, thereby facilitating efficient HMF electro ...
