Structural Color Polymer‐Based Colorimetric Sensor for Detecting Mechanical Stress in Lithium Batteries Separator

open access: yesAdvanced Materials Technologies, EarlyView.
A lithium battery separator displaying a structural color allows the visualization of mechanical phenomena in charging and discharging with color changes. The separator consists of silica nanoparticles and an acrylic polymer, enabling the simultaneous observation of the color changes, bubbles, and crystals.

Unraveling the Effects of Improved Cooling and Bias Force in the Actuation of a Shape‐Memory Soft Multimaterial Gripper

open access: yesAdvanced Materials Technologies, EarlyView.
This study examines a soft gripper with a NiTiCu6 Shape Memory Alloy (SMA) wire embedded in a graphene nanoparticle (GNP)‐functionalized PDMS matrix. Comparing GNP‐enhanced and plain elastomer prototypes, results show that GNPs improve cooling rates, accelerating release by 40%, but increase energy consumption in low‐current activations.

How to Manufacture Photonic Metamaterials

open access: yesAdvanced Materials Technologies, EarlyView.
Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.
