Giant Anisotropic Spin Absorption in Chiral Hybrid Semiconductors

open access: yesAdvanced Materials, EarlyView.
Researchers uncover that chiral hybrid organic–inorganic semiconductors absorb spin differently depending on its polarization direction. This anisotropic spin absorption is primarily driven by the local symmetry breaking within the layered structure.

1T‐to‐2H Phase Evolution During Epitaxial Growth of Transition Metal Dichalcogenides

open access: yesAdvanced Materials, EarlyView.
During MOCVD growth of MoS2 and WSe2, a transient metallic 1T phase emerges in early, edge‐rich, chalcogen‐deficient domains and declines as the films ultimately coalesce as 2H material. Together, experiments and ReaxFF simulations link domain size, edge stoichiometry, and vacancies to this evolution.

Breaking Bottlenecks in Solid Electrolyte Discovery With Large Artificial Intelligence Models

open access: yesAdvanced Materials, EarlyView.
Large AI models are presented as a route to break key bottlenecks in solid electrolyte discovery by linking materials databases, machine‐learning interatomic potentials, large language models, and autonomous experiments. This perspective highlights how AI can accelerate the identification of solid electrolytes with fast ion transport, stable interfaces,

Binder‐Free Direct Ink Writing of Li6.4La3Zr1.4Ta0.6O12 Garnet Electrolytes for All‐Solid‐State Batteries

open access: yesAdvanced Materials Interfaces, EarlyView.
Polymer binders and thick pressed LLZTO pellets limit all‐solid‐state battery integration through grain‐boundary carbon and high ohmic losses. A binder‐free capillary suspension ink is direct‐ink‐written and sintered into 254 μm$\mu{\rm m}$, 95.8%‐dense Ta‐stabilized LLZTO with 17.3 mS cm−1$\text{cm}^{-1}$ bulk conductivity, enabling thinner ...

Range-ambiguous Clutter Separation and Suppression Method for Airborne Bistatic Radar Based on Beam Pattern Reconstruction

open access: yesLeida xuebao
Space-Time Adaptive Processing (STAP) is a key technique used for ground/sea clutter suppression and moving target detection in airborne radar. However, under range ambiguity conditions, the inherent clutter nonstationarity in airborne bistatic radar ...

Three-step ground moving target detection method for bistatic forward-looking SAR

open access: yesThe Journal of Engineering, 2019
Detecting ground moving target in bistatic forward-looking synthetic aperture radar (BFSAR) has become increasingly important in military and civil field. Compared with pulse Doppler radar, the long observation time and high resolution of BFSAR will lead

The Impact of Causal Ambiguity on Competitive Advantage and Rent Appropriation [PDF]

open access: yes, 2010
We seek to develop the conceptual and practical understanding of causal ambiguity. Specifically we extend current thinking by setting out three types of causal ambiguity, based on whether firm resources are perceived to display linkage and/or ...

Spatial Stiffness Programming in Single‐Filament Material Extrusion Through Data‐Driven Thermal Foaming

open access: yesAdvanced Materials Technologies, EarlyView.
Single‐filament material extrusion enables spatial stiffness programming through locally controlled thermal foaming of TPU. A data‐driven G‐code framework tunes porosity from 15.7% to 40.7% and hardness from 90 to 63 Shore A within and across layers. Monolithic hands and soft actuators consequently achieve distinct programmed motions without material ...

Range-Dependent Folded Clutter Suppression for IPPAW-Based Side-Looking Airborne Radar in Nonhomogeneous Environments

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Side-looking airborne radar (SLAR) systems employing conventional waveforms suffer from range ambiguity, whereby near-range clutter is folded into the same range segment as far-range low-velocity target echoes, thereby degrading target detection ...
