The Effect of Alloy Composition on The Dealloying of Ni- and Fe-Based Engineering Alloys in Boiling Caustic Solutions

open access: yesJournal of the Electrochemical Society, 2022
The effect of alloy composition on the dealloying susceptibility of Ni- and Fe-based alloys is studied in near-boiling caustic solutions. A comprehensive comparison of the alloys is performed using electrochemical measurements and nanoscale ...

COMPUTER MODELS OF DEALLOYING IN BINARY METAL NANOPARTICLES

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2019
Two alternative molecular dynamics models (programs) involving the Gupta (tight-binding) potential have been used to reproduce the dealloying phenomenon in the Au – Ag nanoalloy. Program I successively removes Ag atoms from the particle surface layer (we

An atomic view of dealloying [PDF]

open access: yesScience, 2020
Nanomaterials The dealloying of metals to create nanoporous materials with bicontinuous surfaces is often modeled as a surface dissolution and diffusion process, but many of the details lack experimental verification. Liu et al. used liquid-cell high-resolution scanning transmission electron microscopy to follow the nitric acid–driven dissolution of ...

An overview of dealloyed nanoporous gold in bioelectrochemistry [PDF]

open access: yesBioelectrochemistry, 2016
Nanoporous gold (NPG) obtained via dealloying of Au alloys has potential applications in a range of fields, and in particular in bioelectrochemistry. NPG possesses a three dimensional bicontinuous network of interconnected pores with typical pore diameters of ca. 30-40 nm, features that are useful for the immobilisation of enzymes.

Spatially Regulated Silicon Clusters in Trimodal Composite Anodes for High‐Energy Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A trimodal anode architecture spatially regulates silicon clusters within confined interstitial environments formed by graphite and contorted hexabenzocoronene. This confinement suppresses silicon aggregation and localized stress while enabling efficient Li‐ion transport, achieving high‐capacity, stable lithium‐ion batteries.
