Mechanical and Electrochemical Performance of a PETEA‐Based Solid‐State Electrolyte for Multifunctional Structural Battery Composites

Nano Select, EarlyView.
Multifunctional structural battery composites can store electrical energy while bearing mechanical loads, thereby reducing parasitic mass and volume. We present a novel solid‐state PETEA‐based electrolyte, which can be cured in situ after infiltration into the reinforcement fibers in its monomer form.

Reactive Nanoparticle Composed Bilayers: An Alternate Route Toward the Production of Pt/Al Nanofoils

Small, EarlyView.
Spark ablation‐assisted gas phase electrodeposition is an alternate route toward Pt/Al self‐propagation reactive system synthesis. Pt film morphology‐dependent reaction kinetics is a significant advantage. Low spark power and gas flow rate produce porous films and slow speeds, while high power and flow rate give three orders of magnitude faster ...
