Bio-Inspired Hierarchical Micro-/Nanostructures for Anti-Icing Solely Fabricated by Metal-Assisted Chemical Etching [PDF]

open access: yesMicromachines, 2022
We report a cost-effective and scalable methodology for producing a hierarchical micro-/nanostructured silicon surface solely by metal-assisted chemical etching. It involves two major processing steps of fabricating micropillars and nanowires separately.

Zirconium Surface Treatment via Chemical Etching. [PDF]

open access: yesMaterials (Basel), 2023
The increased demand for implants that do not pose a threat to patients diagnosed using high-resolution magnetic resonance imaging and concerns arising from titanium allergies require the development of alternative implant materials. One promising concept is a use of zirconium as corrosion-resistant, nontoxic material that is lower in magnetic ...

Deep Etching of Silicon Based on Metal-Assisted Chemical Etching. [PDF]

open access: yesACS Omega, 2022
A deep etching method for silicon "micro"structures was successfully developed. This wet etching process is based on metal-assisted chemical etching (MACE), which was previously mainly utilized to etch the features that have lateral dimensions of "nanometers." In this novel MACE, the critical improvement was to promote the "out-of-plane" mass transfer ...

Study on the Rapid Preparation of Zinc Oxide Nanotubes by Galvanostatic Etching

open access: yesEurasian Chemico-Technological Journal, 2021
At present, most of the methods for preparing ZnO nanotubes are chemical etching of ZnO nanorods, which is inefficient and takes a long time. In this paper, ZnO nanotubes were successfully prepared by galvanostatic etching.
