Foams‐Induced Hierarchy for Multiscale Photonics on Flat Substrates: Lasing and Mie‐Bragg Diffraction as Case Studies.

open access: yesAdvanced Materials Interfaces, EarlyView.
Ordered and disordered complex configurations displaying two levels of functionality can be fabricated using a simple self‐assembly method involving the foaming and casting of suspensions containing monodisperse spheres on unpatterned flat substrates.

Magnetoelastic Sensing: A Study of Flexible Magnetoelastic Strain Sensors for Highly Deformed Posture Perception

open access: yesAdvanced Materials Technologies, EarlyView.
This study proposes a magnetoelastic strain sensor for highly deformed posture perception. The sensor can maintain stable sensing signal output under significant strain (200%) and at varying stretch rates (ranging from 1000 to 8000 mm min−1). The sensor design is simple and can be applied to soft robots and wearable devices.

Flexible Production of Spherical Powders of Ti‐V‐Zr‐Nb‐Mo‐Hf‐Ta‐W Refractory High‐Entropy Alloys by Plasma‐Assisted Centrifugal Atomization

open access: yesAdvanced Materials Technologies, EarlyView.
In this work, spherical powders of refractory Ti‐V‐Zr‐Nb‐Mo‐Hf‐Ta‐W high‐entropy alloys (R‐HEAs) have been fabricated in a single step by plasma‐assisted centrifugal atomization. Loss of the heaviest elements in the composition is observed only at rotational speeds higher than 13 000 rpm due to solid‐solid centrifugal separation.

Transforming Room Acoustics with Causality‐Driven Dual‐Function Passive Metamaterials

open access: yesAdvanced Materials Technologies, EarlyView.
This work presents an dual acoustic metamaterial for rooms that achieves excellent broadband performance for both sound absorption and sound diffusion. This is done by using causality formulations linking the absorption of the passive system to its volume, yielding an optimal surface area ratio required for excellent sound absorption and while ...

mathematical optimization of rolling stock rotations [PDF]

open access: yes, 2017
We show how to optimize rolling stock rotations that are required for the operation of a passenger timetable. The underlying mathematical ptimization problem is called rolling stock rotation problem (RSRP) and the leitmotiv of the thesis is RotOR, i.e., a highly integrated optimization algorithm for the RSRP. RotOR is used by DB Fernverkehr AG (DBF) in

Piezoelectric Polyurethane/Barium Titanate Composites with High Stretchability and Voltage Output for Energy Harvesting in Soft Wearable Electronics

open access: yesAdvanced Materials Technologies, EarlyView.
Piezoelectric additives are combined with an elastomer host, creating a material with properties of both parent materials: high voltage output and exceptional stretchability. These stretchable piezoelectric materials have the robustness for integration into soft wearable electronics, functioning as renewable energy harvesters to charge capacitors.

Optimizing Metamaterial Inverse Design with 3D Conditional Diffusion Model and Data Augmentation

open access: yesAdvanced Materials Technologies, EarlyView.
A generative AI model, the 3D conditional diffusion model (3D‐CDM), is introduced to enhance the inverse design of voxel‐based metamaterials. A data augmentation technique based on topological perturbation expands the dataset, further improving generation quality and accuracy.
