Photochemical Fuel Carrier Molecules for Robotic Embodied Energy

Advanced Materials, EarlyView.
We designed a novel fuel carrier photoresponsive molecule for on‐demand energy storage and release. Carrier molecules undergo bond scission under UV light to release chemical fuel and locally generate propulsive Marangoni flows. We demonstrate this photochemical embodied energy strategy in small‐scale robots and active matter systems, enabling ...

Study of a Novel Bi‐Layered Thermoplastic Polyurethane Patch for Congenital Diaphragmatic Hernia

Advanced Materials Interfaces, EarlyView.
Large congenital diaphragmatic hernia remains a challenge due to the poor compatibility of current prostheses. To tackle this problem, a bilayer thermoplastic polyurethane patch with tunable mechanical properties is engineered, whose fibrous side supports rapid fibroblast and myoblast colonization, while the smooth film limits adhesions.

Investigation of Structural, Mechanical and Electrochemical Properties of Temperature‐Dependent Dual AlN/TiAlN Coating Synthesized by CVD Process

Advanced Materials Interfaces, EarlyView.
This study investigates thermally CVD‐deposited AlN/TiAlN dual‐layer coatings over a Si substrate, focusing on the temperature‐dependent process‐structure relationship. Systematic characterization reveals that a dense AlN interlayer combined with an optimally deposited TiAlN top layer provides enhancement in mechanical strength, tribological stability,

From Copper Nanoparticles to Alumina Encapsulated Porous Layers With Enhanced Mechanical Stability

Advanced Materials Interfaces, EarlyView.
This study analyzes the synthesis‐structure relation of individual Cu nanoparticles and highly porous nanoparticle‐based Cu films using different sputtering‐based nanoparticle sources. The inherent mechanical instability of the films is tackled with Al2O3 encapsulation through atomic layer deposition, enabling 4‐fold increase in critical force in ...

War of Attrition: Evidence from a Laboratory Experiment on Market Exit [PDF]

We report an experiment designed to study whether inecient rms are systematically driven from overcrowded markets. We implement a series of 3800 wars of attrition of a type modeled in Fudenberg and Tirole (1986).
