A Bio‐Responsive Hydrogel with Spatially Heterogeneous Structure for Treating Infectious Tissue Injuries

open access: yesAdvanced Science, EarlyView.
The hydrogel incorporates Ag⁺‐loaded Preyssler‐type polyoxometalates (POMs) that release Ag⁺ ions in response to endogenous Na⁺ ions, ensuring controlled antibacterial activity. The spatially heterogeneous structure, created through dual‐channel fiber stacking and in situ cross‐linking, enhances structural integrity and promotes tissue regeneration ...

Adaptive Urban Planning: A Hybrid Framework for Balanced City Development [PDF]

open access: yesarXiv
Urban planning faces a critical challenge in balancing city-wide infrastructure needs with localized demographic preferences, particularly in rapidly developing regions. Although existing approaches typically focus on top-down optimization or bottom-up community planning, only some frameworks successfully integrate both perspectives.

Atomic‐Level Strain Sensing and Piezoresistance Effect in a 1D Single‐Atom Chain

open access: yesAdvanced Science, EarlyView.
The atomic‐scale piezoresistance effect of the Ag single‐atom chain is explored using strain characterization and electrical measurement. Single‐atom chain has the potential to serve as a strain sensor with atomic‐level precision, overcoming the challenge of low temporal resolution in a transmission electron microscope.

Natural Toolbox–Chemical Engineering Aspect and High‐Value Applications of Janus Cellulose Nanomaterials

open access: yesAdvanced Science, EarlyView.
The Tai Ji symbol from China represents the co‐existence of two opposite substances, similar to quantum entanglement. The term Janus comes from ancient Roman religion and mythology. Janus, the god of beginnings, transitions, etc., has two faces, symbolizing duality. Janus cellulose nanomaterials show structural duality.

Single‐Pixel Infrared Miniaturized Spectrometer Enabled by Ultra‐Broadband Reconfigurable Photodetection

open access: yesAdvanced Science, EarlyView.
A near‐infrared tunable micro‐spectrometer is achieved by integrating a PbS photodetection unit and a light modulation unit based on liquid crystal tuned optical resonances, demonstrating a wavelength tuning range exceeding 850 nm. This micro‐spectrometer shows high fidelity in spectral reconstruction and is also successfully applied to plastic sorting,

The FGF13‐Caveolin‐1 Axis: A Key Player in the Pathogenesis of Doxorubicin‐ and D‐Galactose‐Induced Premature Cardiac Aging

open access: yesAdvanced Science, EarlyView.
The FGF13 level is significantly downregulated in premature aging murine hearts subject to D‐galactose and Doxorubicin. FGF13 overexpression and deficiency exacerbated and alleviated Doxorubicin/D‐galactose‐induced myocardial aging characteristics and functional impairment, respectively.
