Holographic Whole‐Object Photopolymerization Preserving Director Alignment in Liquid Crystalline Actuators

open access: yesAdvanced Materials, EarlyView.
Holographic microlithography enables the fabrication of fully connected 3D liquid crystalline structures in a single exposure. The process maintains precise control over the director orientation within the entire object, preventing local director distortions typically observed in sequential printing.

Superionic Amorphous Li2ZrCl6 and Li2HfCl6

open access: yesAdvanced Materials, EarlyView.
Amorphous Li2HfCl6 and L2ZrCl6 are shown to be promising solid‐state electrolytes with predicted ionic conductivities >20 mS·cm−1. Molecular dynamics simulations with machine‐learning force fields reveal that anion vibrations and flexible MCl6 octahedra soften the Li coordination cage and enhance mobility. Correlation between Li‐ion diffusivity and the

The Microstructure and High‐temperature Cycle Oxidation Mechanism of the Nickel‐Based Superalloy Surface Treated by Laser Shock Processing and Ion Implantation at 1100 °C

open access: yesAdvanced Materials Interfaces, EarlyView.
Laser shock processingcombination with Hf ion implantation results in dual modification on the surface of GH202 nickel‐based superalloy, which induces a large number of crystal defects, providing channels for the diffusion of metal cations. Hf ion implantation forms an amorphous HfO2 layer.

Polystyrene/TiO2 Composite Thin Films by Powder Aerosol Deposition: Film Morphology Control Through Powder Processing

open access: yesAdvanced Materials Interfaces, EarlyView.
It's all in the mix! By employing different homogenization strategies for preparing polystyrene/TiO2 polymer‐ceramic composite (PCC) powders, we tune the morphology of PCC films obtained by powder aerosol deposition, ranging from segregated multilayer‐like to finely blended composites.

Designing Defect Structure and Interfacial Strain in an Epitaxial VN Bilayer Film by Tailoring N Concentration

open access: yesAdvanced Materials Interfaces, EarlyView.
The N concentration in an epitaxial VN bilayer is tailored from overstoichiometric V0.49N0.51 to understoichiometric V0.56N0.44. Based on ab initio, diffraction, and microscopy data, the overstoichiometric V0.49N0.51 layer contains V vacancies, N Frenkel pairs, and a high density of dislocations.

Cellulose‐Nanofiber‐Based Layered Sub‐Terahertz Absorbing Sheets for B5G/6G Applications

open access: yesAdvanced Materials Technologies, EarlyView.
We report a sub‐terahertz absorber made of biodegradable cellulose‐nanofiber (CNF), potentially useful for B5G/6G devices to achieve electromagnetic compatibility in an eco‐friendly way. The absorber is 120 µm thick and consists of two carbon‐nanotube‐dispersed CNF layers and one pure CNF layer.
