Chemical etching of titanium samples
Periodica Polytechnica Mechanical Engineering, 2013 We studied chemical etching treatment on the surface of titanium implant materials, specifically 2 mm thick Grade 2 and nanoparticulate titanium discs, aiming to modify the surface roughness of samples. For chemical etching we investigated changes in reaction time on the surface (15-600 seconds). During the research we obtained the changes of thickness,

Chemical etching of silicon assisted by graphene oxide under negative electric bias. [PDF]
Nanoscale AdvChemical etching of silicon assisted by graphene oxide (GO) is attracting attention as a new method to fabricate micro- or nano- structures. GO promotes the reduction of an oxidant, and holes are injected into silicon, resulting in the preferential ...

Wet chemical thinning of molybdenum disulfide down to its monolayer
APL Materials, 2014 We report on the preparation of mono- and bi-layer molybdenum disulfide (MoS2) from a bulk crystal by facile wet chemical etching. We show that concentrated nitric acid (HNO3) effectively etches thin MoS2 crystals from their edges via formation of MoO3 ...
