Study on the two dealloying modes in the electrooxidation of Au–Sn alloys by in situ Raman spectroscopy

In situ observation of liquid metal dealloying and etching of porous FeCr by X-ray tomography and X-ray diffraction

“…In the last decades, the attraction of nanoporous metals due to their excellent functional properties have risen [1][2][3][4]. Because of their availability, cost and abundance, porous structures of common metals such a-Ti-based, Fe-based...) alloys are highly desired for various applications including energy-harvesting devices [5].…”

“…Dealloying by free corrosion in an aqueous solution has already been studied by various methods such as in situ electrochemical noise or Raman spectroscopy, for example [4,[21][22][23]. It was even 3D imaged in situ to study the evolution of the dealloying front and coarsening and the effect of different parameters on the dealloying process such as precursor composition or acid concentration [24][25][26].…”

Anodically-bondable LTCC substrates with novel nano-structured electrical interconnection for MEMS packaging

“…Nanoporous metals is widely studied on science and material researches since reported in Nature in 2001 [3] however its functionalities are missed out on applied researches. In general, nanoporous metals are made by dealloying an alloy sheet [4,5] or electroplated alloy structures [6]. Usually, the electrodeposition of gold alloy on microelectronic devices is performed using a bath containing gold cyanide complexes due to their highest stability coefficients.…”

Study on the electrodissolution and roughening of a palladium electrode in chloride containing solutions

“…Raman spectroelectrochemistry is a promising tool to understand the physicochemical processes that occur at these metal/solution interfaces on the molecular level, and has been employed to investigate the electrodissolution course of many metals like Cu [1,2], Au [3][4][5], Co [6], Hg [7], Fe [8][9][10], Fe-P [11], carbon steel [12][13][14][15], Au-Sn [16], Pt-Ni alloy [17] and so on.…”
