Bio-Inspired Hierarchical Micro-/Nanostructures for Anti-Icing Solely Fabricated by Metal-Assisted Chemical Etching [PDF]
Micromachines, 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]
Materials (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]
ACS 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 ...

Numerical and experimental studies of the carbon etching in EUV-induced plasma [PDF]
, 2016 We have used a combination of numerical modeling and experiments to study carbon etching in the presence of a hydrogen plasma. We model the evolution of a low density EUV-induced plasma during and after the EUV pulse to obtain the energy resolved ion ...

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