Background Nanoporous metals, especially copper, are critical in fields like hydrogen production, battery technology, and energy storage due to their high surface area and conductivity. However, traditional sintering methods require high temperatures, which often reduce porosity and compromise performance. Additionally, the mechanical instability of...

­Background Nanoparticle-based metallic powders are of interest for rapid sintering, thermal bonding, and electrically conductive metal pastes due to its unique properties, such as lower sintering temperature compared to bulk counterparts and efficient light absorption for photonic curing. However, there are some drawbacks associated with the production,...

Metal-assisted chemical imprinting (Mac-Imprint) is a contact-based wet etching process that combines metal-assisted chemical etching (MACE) and nanoimprint lithography (NIL). Mac-Imprint processes have been used for semiconductor patterning with arbitrary and complex 3D micro- and nano-structures. While porous catalytic metal thin-films can be used...
