Reversible Phase Transitions of Anionic and Cationic Surfactant Mixtures Drive Shape Morphing Droplets

open access: yesAdvanced Materials, EarlyView.
A light‐controlled, reversible phase transition of ionic surfactant assemblies, coupled with dynamic partitioning between bulk phases and interfaces, induces rapid, and order‐of‐magnitude changes in oil–water interfacial tension. Surpassing the capabilities of conventional stimuli‐responsive surfactants, this transient, collaborative mechanism enables ...

Boosting capacitive blue-energy and desalination devices with waste heat

open access: yes, 2014
We show that sustainably harvesting 'blue' energy from the spontaneous mixing process of fresh and salty water can be boosted by varying the water temperature during a capacitive mixing process.

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.
