Spatial Coordination Structure‐Driven Enzyme‐Like Selectivity in Single‐Atom Nanozymes

open access: yesAdvanced Materials, EarlyView.
Sun et al. reviews recent progress in enhancing the enzyme‐like catalytic selectivity of SAzymes through the rational design of their spatial coordination structures. They emphasize the structure‐activity relationships of various attributes of these coordination structures in promoting selective catalytic behavior, the strategic design of coordination ...

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.

Pick‐and‐Place Grippers with Tunable Adhesion from Capped Soft Hollow Pillar Structure

open access: yesAdvanced Materials Technologies, EarlyView.
Mushroom‐shaped soft hollow pillars (SHPs) with a mushroom cap, or capped SHPs (C‐SHPs) are introduced for improved tunable adhesion under pneumatic actuation. The mushroom cap optimizes stress distribution and alters crack initiation on the contact interface, leading to significantly improved adhesion strength and tunability.

High‐Resolution Stereolithography of Amorphous, Dense and Mechanically Stable Bioactive Glass

open access: yesAdvanced Materials Technologies, EarlyView.
Porous scaffolds made of bioactive glass are of great interest for bone tissue engineering. The geometry and resolution of the scaffold is impacting its bioactive and mechanical performance. Utilizing stereolithographic 3D printing of bioactive glass, human cancellous bone scaffolds, and other structures are fabricated with features as small as 77 µm ...
