Transition Metal Dichalcogenide‐Based Composites in Powder Bed Additive Manufacturing for Electrochemical Applications—A Review

open access: yesAdvanced Materials Technologies, EarlyView.
The robust electrochemical sustainability of additively manufactured high‐performance nanocomposites is substantially dependent on overcoming material selection, process optimization, operational scalability, and design flexibility challenges. Integrating transition metal dichalcogenides into metal‐matrix composites, laser powder bed fusion directly ...

Streamlined Inkjet‐Printing of Stretchable Organic Photodetectors

open access: yesAdvanced Materials Technologies, EarlyView.
This work introduces stretchable photodetectors fully inkjet‐printed on stretchable substrates. It is demonstrated that printed stiff platforms effectively decouple strain from the stretched substrate and serve as a chemically resistant and mechanically rigid platform.

A MEMS Electromagnetic Vibration Energy Harvester with Monolithically Integrated NdFeB Micromagnets

open access: yesAdvanced Materials Technologies, EarlyView.
50µm thick sputtered arrays of NdFeB micromagnets are directly integrated into a functional MEMS in‐plane electromagnetic vibration energy harvester. A combination of analytical modeling and numerical simulations guided the design of the magnet arrays and ad‐hoc coil, to produce a high transduction factor.

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.

Frequency‐Selective Terahertz Wave Amplification by a Time Boundary in Huygens' Metasurface

open access: yesAdvanced Optical Materials, EarlyView.
In a free‐standing all‐dielectric Huygens' metasurface, ultrafast pulsed laser excitation is used to establish the time boundary for a coherent modulation to the electric and magnetic polarizability in the adiabatic limit. Amplification of THz waves at frequencies that can be continuously tuned have been achieved, showing an effective energy gain up to

Selective Color Appearance of Liquid‐Crystal‐Aided Laser‐Induced Periodic Surface Structures

open access: yesAdvanced Optical Materials, EarlyView.
Self‐assembled nano trenches on transparent electrodes are produced by irradiating femtosecond laser, and then combined with liquid crystal, showing brilliant selective color, which is electronically switchable. The nano trenches diffract light, and those totally internally reflected light propagates in the liquid crystal cell.

Locking in Color: Stable RGB Perovskite Nanocrystal Films via UV Cross‐Linking

open access: yesAdvanced Optical Materials, EarlyView.
Combining block copolymer stabilized lead halide nanocrystals with a UV light‐based cross‐linking procedure yields ultra‐stable nanocrystal thin films, which are resistant to dissolution by organic solvents and impervious to interlayer ion exchange. This allows for the fabrication of stacked layer RGB all‐perovskite white light‐emitting phosphors with ...
