Dealloying, the selective dissolution of less noble elements from an alloy, enables the
preparation of monolithic macroscale bodies, which at the nanostructure level exhibit a …

Metallic actuators have increasingly shown the potential to replace conventional
piezoelectric ceramics and conducting polymers. However, it is still a great challenge to …

Nanoporous metals have been used as electrochemical metallic actuators to generate large
charge-induced strain at the electrode/electrolyte interface for twenty years. However, the …

In aqueous solutions, electro/chemically deposited metals usually grow outward into
electrolyte. Here we report that the reduced Al grows inward into the sample, surprisingly …

Metallic actuator materials have been comprehensively studied during the last twenty years,
but the studies have been limited to noble metals to date. Here we report reversible …

At present, metal/metal oxide composites are considered as potential oxygen reduction
reaction (ORR) catalysts for energy-related applications like fuel cells. Here, we fabricated a …

Metallic actuators have recently aroused great interests, and alloying of noble element with
earth-abundant metal is essential to lower the cost of actuation materials while keeping a …

In recent years, studies have shown that Nanoporous (NP) metals deform in a relatively
brittle manner under tensile loading. We investigated the mechanical performance of NP …

The utilization of nanoporous copper (np-Cu) as a metallic actuator has gained attention in
recent years due to its cost-effectiveness in comparison to other precious metals. Despite …

Nanoporous metallic actuators for artificial muscle applications are distinguished by
combining the low operating voltage, which is otherwise reserved for polymer-based …
