Advanced Science, EarlyView.Pattern‐dependent etching is converted into a physical prior for intelligent reconstruction of high‐aspect‐ratio silicon structures. Combining YOLO‐Pose feature extraction with a topography network, the framework retrieves depth, sidewall angle, and scallop texture from minimal destructive observations, enabling accurate cross‐scale metrology and near ...

Advanced Science, EarlyView.NiNb alloys enable efficient charge‐to‐spin conversion by combining the spin Hall effect of nickel with the orbital Hall effect of niobium. Composition tuning yields spin‐torque efficiencies of −1.4 to −1.7 and a non‐monotonic efficiency‐resistivity relationship, revealing orbital‐spin synergy beyond conventional spin Hall materials and offering a ...

Temperature dependence of heavy quark diffusion from (2+1)-flavor lattice QCD
Journal of High Energy PhysicsWe present a lattice determination of the heavy-quark diffusion coefficient in (2+1)-flavor QCD with almost physical quark masses. The momentum and spatial diffusion coefficients are extracted for a wide temperature range, from T = 163 MeV to 10 GeV. The

Unveiling the Ultralow Thermal Conductivity of Hybrid Perovskites
Advanced Science, EarlyView.In hybrid perovskites, thermal energy flows through lattice vibrations of the framework (48%–65%) and organic molecules (35%–52%). When the disorder introduced by organic molecules is excluded, the temperature dependence of the vibrational thermal conductivity results from the lattice framework transits from ∼T0 to ∼T−1, and the value doubles at room ...

Photo‐Gated Corona Microfluidics
Advanced Science, EarlyView.Photo‐gated corona microfluidics decouples optical programming from electric‐field actuation to enable reconfigurable manipulation on open, electrode‐pattern‐free surfaces. Near‐infrared irradiation locally melts paraffin, creating a reversible charge‐relaxation pathway that reconstructs the electric field.

Engineering Slow‐Carrier Interfacial Recombination Enables Tailored Spectral Response
Advanced Science, EarlyView.This work demonstrates that weak‐drift slow carriers are preferentially captured at generic semiconductor surfaces/interfaces and recombine. This process is manipulated to achieve tailored spectral response. A tens of µm‐wide depletion region is created to observe surface collection rates for photocarriers generated at different positions.

Sheet‐Size‐Dependent Mosaicity of 2D Phyllosilicate Membranes
Advanced Science, EarlyView.This study explores how the size of 2D vermiculite sheets affects the structure of laminar membranes. High‐resolution x‐ray diffraction reveals how sheet size governs structural disorder and crystallinity. These changes directly impact ion permeability.

Photoelectric Imaging of the Optically Inactive Charge State of Silicon‐Vacancy Defects in Diamond
Advanced Science, EarlyView.Although the doubly negative charge state of the SiV center in diamond is predicted to ionize only in the ultraviolet and is therefore considered optically inaccessible, we demonstrate visible‐range photoelectric imaging enabled by a previously unrecognized regime of laser‐assisted tunneling. ABSTRACT The investigation of optically active point defects

Advanced Science, EarlyView.A Sr‐free air electrode for high‐temperature solid oxide cells is designed by independently tailoring electronic conduction, ionic transport, and surface catalysis using complementary Sr‐free phases and infiltrated nanocatalysts. It delivers performance comparable to state‐of‐the‐art Sr‐containing electrodes while completely suppressing Cr‐induced ...

Nanoscale Confinement Enhances Ultrafast Demagnetization
Advanced Science, EarlyView.Next generation spintronics may depend on successfully combining femtosecond spin dynamics with nanoscale device miniaturization. We address this by systematically studying the effect of nanoscale confinement on the femtosecond demagnetization of Iron. By combining ultrafast experiments sensitive to spins, charge carriers, and phonons, we uncover a nm ...
