3D Printing and Chemical Dealloying of a Hierarchically Micro- and Nanoporous Catalyst for Wastewater Purification.

ACS Applied Materials and Interfaces, 2021
Hierarchically porous-structured materials show tremendous potential for catalytic applications. In this work, a facile method through the combination of three-dimensional (3D) printing and chemical dealloying was employed to synthesize a nanoporous ...

The Effect of Temperature on Dealloying Mechanisms in Molten Salt Corrosion

Journal of the Electrochemical Society, 2022
The mechanism of molten salt corrosion of Ni− and Fe-based model alloys is studied at different homologous temperatures relevant to molten salt nuclear reactor application.

Dealloying and Dealloyed Materials

Annual Review of Materials Research, 2016
A successful working model for nanoporosity evolution during dealloying was introduced 15 years ago. Since that time, the field has rapidly expanded, with research groups from across the world studying dealloying and dealloyed materials. Dealloying has grown into a rich field, with some groups focusing on fundamentals and mechanisms of dealloying ...

Passivation-driven speciation, dealloying and purification

Materials Horizons, 2021
Kinetics of passivating oxide growth can drive nanoscale surface order/speciation. Combined with oxide growth and thermal expansion, trapped oxide crystals (‘ship-in-a-bottle’) or extrusion of metal fingerlings (‘spiky particles’) can be achieved.

Electroless Dealloying of Thin-Film Nanocrystalline Au-Ag Alloys: Mechanisms of Ligament Nucleation and Sources of Its Synthesis Variability.

ACS Applied Materials and Interfaces, 2022
Control of ligament size in nanoporous gold through process inputs in chemical dealloying holds the potential to exploit its size dependent properties in applications in energy and biomedicine.

Dealloying of Magnesium Alloys

ECS Meeting Abstracts, 2015
The corrosion behavior of cast Mg-Al alloys such as AZ91D and AM60B is strongly dependent on the alloy composition and microstructure.  Alloy grain size, area fraction of phases and spatial distribution of the phases are important factors governing both full immersion and atmospheric corrosion behavior.

Ageing of dealloyed copper

Journal of Materials Science, 1990
A finely divided copper rod structure has been prepared by the selective dissolution of aluminium from a Cu-50wt% Al alloy in aqueous NaOH. The aging behaviour of this product has been studied by measurement of the coarsening of the pore and copper rod structure.

The Dealloying Critical Potential

Journal of The Electrochemical Society, 2002
This paper reexamines the concept of the dealloying critical potential by considering the critical potential to be a kinetically controlled morphological transition dependent not only on extensive system parameters such as alloy and electrolyte composition, but also on the rate of application of an intrinsic parameter such as the potential ramp rate ...
