Mussel‐Bioinspired Edible Ca2+‐Crosslinked Alginate Hydrogel Electrodes for Glucose Gastrointestinal Monitoring

open access: yesAdvanced Science, EarlyView.
A fully edible soft electrode is engineered from Ca2⁺‐crosslinked alginate integrated with polydopamine, silver nanoparticles, and food‐grade glucose oxidase. The hybrid hydrogel combines ionic and electronic conduction, enabling efficient glucose‐to‐H2O2 conversion and catalytic reduction in simulated intestinal fluid.

On the influence of non-linearity within two-phase poro-elasticity: Numerical examples and counterexamples

open access: yesExamples and Counterexamples
Porous materials can be described either by Biot’s consolidation theory or the Theory of Porous Media (TPM). Depending on the loading regime, permeability or compressibility of the solid matrix, either small or finite deformations occur.

3D‐MOF‐Lattice Inspired Programmable Metamaterials Based on Reconfigurable Polyhedral Origami

open access: yesAdvanced Science, EarlyView.
A novel metamaterial design strategy: inspired by MOFs crystal networks, creating reconfigurable modular polyhedral units to overcome the limitations of traditional materials. These modules exhibit adjustable stiffness, bistability, and Poisson's ratio that can be adjusted from negative to positive values.

Photochromism‐Driven Full Solar Spectrum Absorption for Efficient Photo‐Thermo‐Electric Conversion

open access: yesAdvanced Science, EarlyView.
After electron‐transfer photochromism, a black viologen‐based organic compound shows full solar spectrum absorption (250–2500 nm) and near‐infrared photothermal conversion efficiency (NIR‐PCE) >60%. Integrated with a thermoelectric generator, it outputs 1.17 V under 4 Suns irradiation, enough to drive a small fan via photo‐thermo‐electric conversion ...

Macrophagic Sclerostin Loop2‐ApoER2 Interaction Required by Sclerostin for Cardiovascular Protective Action

open access: yesAdvanced Science, EarlyView.
Sclerostin loop2‐ApoER2 interaction in macrophages is required by sclerostin to suppress NF‐κB nuclear translocation and phosphorylation, to promote macrophage conversion into anti‐inflammatory subtypes in atherosclerotic aortas, as well as to prevent atherosclerosis and aortic aneurysm development in ApoE−/− mice. Abstract Therapeutic antibody against

Direct Probing of Trap Dynamics in β‐Ga2O3 Schottky Barrier Diodes Using Single‐Voltage‐Pulse Characterization

open access: yesAdvanced Science, EarlyView.
A single‐pulse approach uncovers trap dynamics in β‐Ga2O3 Schottky barrier diodes. Transient current profiling reveals rapid electron capture, delayed trap filling, and clear thermal effects. Extracted trap densities, capture time constants, and activation energies indicate that this simple pulse technique enables effective evaluation of trap states ...

Piezo‐Phototronic PVDF/HfO2/Nano‐Cu Heterostructured Thin Film for Flexible Self‐Powered Multimodal Sensing

open access: yesAdvanced Science, EarlyView.
Electrospinning a composite of PVDF, HfO2, and nano‐Cu transforms the discrete precursors into a continuous nanofiber mesh, forming a multi‐interface heterostructure with embedded nanoparticles. The presence of HfO2 and nano‐Cu at the fiber interfaces induces a highly aligned β‐phase, which enhances piezoelectric crystallinity and improves the material'
