Understanding the Dynamics of Nanoparticle Formation and Evolution in Functional Oxides via In Situ SAXS/WAXS

open access: yesAdvanced Materials Interfaces, EarlyView.
In situ SAXS/WAXS enables real‐time tracking of nanoparticle formation and evolution in exsolved and infiltrated Ni‐based perovskites under reducing conditions. The combined technique captures nucleation, growth, and coarsening dynamics with high temporal resolution, providing statistically robust insights into structural and morphological ...

Energy- and Regularity-Dependent Stability Estimates for Near-Field Inverse Scattering in Multidimensions

open access: yesJournal of Mathematics, 2013
We prove new global Hölder-logarithmic stability estimates for the near-field inverse scattering problem in dimension d≥3. Our estimates are given in uniform norm for coefficient difference and related stability efficiently increases with increasing ...

Advanced Design for Weakly Coupled Resonators by Automatic Active Optimization

open access: yesAdvanced Materials Technologies, EarlyView.
An Automatic Active Optimization (AAO) strategy integrates machine learning predictors and genetic algorithms in a closed‐loop workflow. By iteratively expanding its dataset with new discoveries, AAO overcomes the limits of conventional methods. This approach finds superior microstructural designs beyond the initial sample space. We demonstrate this on

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

open access: yesAdvanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Application of solving inverse scattering problem in holographic bulk reconstruction

open access: yesJournal of High Energy Physics
We investigate the problem of bulk metric reconstruction in holography by leveraging the inverse scattering framework applied to boundary two-point correlation functions. We generalize our previous work of scalar field and show that reconstruction can be
