Optofluidic Raman Analysis and Capacity Recovery in Li‐ion Cells

open access: yesAdvanced Materials Technologies, EarlyView.
Operando Raman spectroscopy is used to monitor the degradation of commercial Li‐ion cells. Using a microfluidic access port, small amounts of electrolyte are sampled into a hollow‐core optical fibre, where fibre‐enhanced Raman analysis reveals Li+ solvation changes and solvent evolution.

Ultrafast (1‐5 sec) Lamination of Perovskite Solar Cells With Self‐Encapsulation Using Rapid Joule Heating

open access: yesAdvanced Materials Technologies, EarlyView.
Halide perovskite solar cells are fabricated with self‐encapsulation by lamination between two glass substrates using rapid Joule heating, yielding a 99% reduction in lamination time compared to previous studies. An 18% efficient cell is laminated in 5 s, demonstrating the potential for scalable manufacturing. ABSTRACT Perovskite solar cells (PSCs) are

Dynamic Current Routing in Conductive Liquid Crystal Elastomers for Complex Deformation Actuators

open access: yesAdvanced Materials Technologies, EarlyView.
This work introduces a novel actuation control strategy in which electrical stimulation generates localized Joule heating in conductive liquid crystal elastomer (LCE) surfaces, enabling complex 3D deformations from a single homogeneous surface without preprogramming.

New Directions in Focused Ion Beam Induced Deposition for the Nanoprinting of Functional 3D Heterostructures

open access: yesAdvanced Materials Technologies, EarlyView.
Here, it is shown that focused ion beam induced deposition (FIBID) using helium and neon ions enables advanced high‐resolution 3D nanoprinting achieving precise multimaterial architectures and engineered internal voids. Thus, FIBID with finely focused noble gas ion species is presented as a unique platform for designing functional nanomaterials for ...
