Development of Laterally Graded X‐Ray Multilayer Optics
Advanced Materials Technologies, EarlyView.This work presents the development of laterally graded X‐ray multilayer optics with both constant and variable lateral gradients. By precisely controlling substrate speed profiles and mask design, these multilayers achieve highly accurate lateral gradients and excellent sagittal thickness uniformity, making them ideal for spectroscopy application at ...

Advanced Design for Weakly Coupled Resonators by Automatic Active Optimization
Advanced 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

Convexity of level sets for solutions to nonlinear elliptic problems in convex rings
Electronic Journal of Differential Equations, 2006 We find suitable assumptions for the quasi-concave envelope $u^*$ of a solution (or a subsolution) $u$ of an elliptic equation $F(x,u, abla u,D^2u)=0$ (possibly fully nonlinear) to be a viscosity subsolution of the same equation.

Advanced 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 ...

Molecular Inks for the Development of Complex 3D In‐Mold Electronics
Advanced Materials Technologies, EarlyView.Molecular inks (MINKs) enable the fabrication of thermoformed 3D circuits by decoupling the forming and metallization steps. Following thermoforming, intense pulsed‑light or thermal processing converts the patterned MINKs into complex 3D conductive tracks with improved stretchability and electrical performance, advancing low‑cost, high‑performance in ...
