Synergistic Charge Scavenging in Pt/C‐Polyoxometalate Systems for Scalable Biomass Power Generation via Super‐Reduced Electrolytes

Advanced Science, EarlyView.
Synergistic charge scavenging between Pt/C and liquid polyoxometalate mediators effectively dismantles the inherent biological recalcitrance of raw biowaste. This dynamic interfacial electron transfer unlocks a multi‐electron super‐reduced state (>4 electrons). By overcoming traditional electron‐harvesting ceilings, this approach enables scalable, high‐

Steric‐Pressure‐Driven Topological Reconstruction for High‐Performance Zintl Phase Thermoelectrics with Machine‐Learning Validation

Advanced Science, EarlyView.
Synergistic Sr and Ag co‐doping drives steric‐pressure‐induced reconstruction from a 2D layered structure to a cross‐linked 3D framework in the Ca9‐xSrxZn4+y‐zAgzSb9 system, enhancing carrier mobility while maintaining a large Seebeck coefficient and doubling ZT to 0.73 at 873 K, with hybrid transfer machine learning further capturing the compositional

Combinatorial Survey of Structural Phase Distribution and Magnetism in Fe‐Ge‐Te Composition‐Spread Thin Film Libraries

Advanced Electronic Materials, EarlyView.
ABSTRACT Magnetic 2‐dimensional (2D) van der Waals (vdW) materials have garnered tremendous attention. The vdW ferromagnet Fe5Ge1Te2 has a Curie temperature Tc of ≈ 270 K, which is tailorable by tuning the stoichiometry and the Fe deficiency to reach room temperature.

Determining the Relationship Between Composition, Structure, and Device Properties of GexSe1‐x‐Based Selector‐Only Memory

Advanced Electronic Materials, EarlyView.
Composition‐dependent structural evolution in GeXSe1‐X selector‐only memory (SOM) is correlated with device switching behavior. Increasing Ge strengthens network rigidity, suppresses atomic motion, and stabilizes threshold switching, while narrowing the memory window. The revealed structure–property relationship provides a guideline for compositionally

Oxygen‐Scavenging‐Driven Interlayer Engineering for Balancing Linearity and Retention in IGZO Synaptic Memristors

Advanced Electronic Materials, EarlyView.
Oxygen‐scavenging‐induced self‐formed interlayers regulate Schottky‐barrier modulation in IGZO memristors, producing a fundamental trade‐off between synaptic update linearity and retention. A preserved AlOx interlayer moderates voltage distribution and enables gradual, nearly linear conductance updates, whereas a soft‐broken SiO2 interlayer provides a ...

Handover Strategy for LEO Satellite Networks Using Bipartite Graph and Hysteresis Margin

IEEE Open Journal of the Communications Society
The low Earth orbit (LEO) satellite constellation has become a highly effective solution for non-terrestrial networks (NTN), offering reliable, uninterrupted, and high-speed global communication. However, the rapid movement of LEO satellites results in a

Dual‐Defect‐Engineered Zinc Oxynitride Thin‐Film Transistors Enabling Electrostatic Current Balancing in Geometrically Symmetric Oxide Logic

Advanced Electronic Materials, EarlyView.
Dual‐defect engineering controls subgap states in zinc oxynitride (ZnON) thin‐film transistors, yielding a field‐effect mobility of 26.58 cm2 V−1 s−1. A process‐associated threshold‐voltage shift is repurposed within a dual‐gate depletion‐mode load to electrostatically balance current in a geometrically symmetric NMOS inverter.

Dimensional Reduction of Transition Metal Dichalcogenides by Oxide Insertion: Quasi‐1D Oxychalcogenide Semiconductors

Angewandte Chemie, EarlyView.
Molecular Scissors: Oxide insertion slices the layers of MQ2 transition metal dichalcogenides (TMDs) into one‐dimensional [M3Q6] nanoribbons, giving a new family of A2Hf3Q6O (A = K, Rb, Cs; Q = S, Se) oxychalcogenides. The heteroanion‐driven dimensional reduction yields direct‐gap semiconductors with optical absorption that is tunable across the ...
