Lithography‐Free Site‐Specific Synthesis of Size‐Tailored Platinum Dichalcogenides

Advanced Materials Technologies, EarlyView.
This study proposes a streamlined strategy for synthesizing site‐specific, size‐tunable Pt dichalcogenides by pre‐defining Pt templates via focused ion beam (FIB). Utilizing only FIB and thermal treatment, this approach reduces processing steps and avoids issues like carbon contamination and edge defects from lithographic etching.

A Review on Microreactor Design for Effective Fischer–Tropsch Process Intensification

Advanced Materials Technologies, EarlyView.
Design strategies for effective Fischer–Tropsch process intensification are summarized based on experimental and simulation experiences. Recommendations for catalyst loading of packed‐bed and wash‐coated microchannel, microtube, micromonolith, and microstructured reactors are discussed.

Ultra‐Thin Soft Pneumatic Actuation for Minimally Invasive Neural Interfacing

Advanced Materials Technologies, EarlyView.
Parylene C is a common polymer in bioelectronics, favored for its biological and chemical inertness. However, this makes bonding layers of Parylene C together very challenging. Here it is a laser to selectively weld layers of Parylene C to create high‐pressure fluidic actuation devices.

Mode‐dependent Far‐field Radiation of Circularly Polarized Light by a Single Plasmonic Nanohelix

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
The numerical simulations explored the chiroptical response and far‐field radiation behaviors of single plasmonic nanoantennas transitioning into helical structures. This study highlights the ability of these plasmonic nanohelices to regulate the far‐field directionality of radiation power and circular polarization in plasmon‐exciton coupled systems ...

Double Bouligand Printed Twisted Stacks: Mirrored Chiroptical Polarization and Enhanced Compressive Mechanics

Advanced Optical Materials, EarlyView.
This work demonstrates the production of nature‐inspired double Bouligand structures via shear‐aligning cellulose nanocrystals for comparison against more commonly studied single Bouligand architecture. Optical and mechanical analysis shows retained chiroptical polarization and increased mechanical integrity under compression elucidated with ...
