“…On the other hand, the periodicity of LIPSSs on the 304 stainless steel surfaces in water, 5 and 10 wt% NaCl solutions, 5 and 10 wt% NaNO 3 solutions, 5 and 10 wt% Cu(NO 3 ) 2 solutions and 5 and 10 wt% CuSO 4 solutions was about 600 nm, which was about 0.56 times the laser wavelength since the refractive index of water is 1.33 [ 45 ], shortening the laser wavelength and the wavelength of the surface plasma waves. In the solutions, the periodicity is approximately the same since the refractive index of 5 and 10 wt% NaCl solutions, 5 and 10 wt% NaNO 3 solutions, 5 and 10 wt% Cu(NO 3 ) 2 solutions and 5 and 10 wt% CuSO 4 solutions is close to the refractive index of water [ 46 , 47 , 48 , 49 , 50 ].…”

Short-pulsed laser-induced periodic surface structures (SPLIPSSs) have the possibility to control tribology, wettability and biocompatibility. Nevertheless, the optimal structure depends on each functionality, which has not been clarified. The hybrid process with a short-pulsed laser and electrochemical machining (SPLECM) is, then, proposed to fabricate micro/nano hybrid structures and to modify the surface composition for providing high functionalities with material surfaces. Electrochemical machining is a well-established micro-elution and deposition method with noncontact between a workpiece and a tool. In this study, the effects of electrolytes on SPLIPSSs were investigated experimentally by the picosecond laser irradiation on 304 stainless steel substrates in various electrolytes. The geometry of SPLIPSSs depended on the types and the concentration of electrolytes. In the case of copper nitrate solution and copper sulfate solution, LIPSSs and spheroidization of copper were obtained. This study demonstrated the possibility of SPLECM to fabricate micro/nano structures and to control surface composition.

“…The researches of volume and transport properties of solutions of copper(II) nitrate trihydrate in DMSO have shown that the maximum of conductivity is observed in 0.4 M solution of copper(II) nitrate in DMSO at 15 0 C that is changed till 0.6 M at higher temperatures 13 . In this connection, for studying of possibility of electrodeposition of copper powder from dimethylsulphoxide the interval of concentration of copper salt was chosen 0.1-0.6 M. In solutions with concentration of 0.5 M of copper salt in DMSO and higher the viscosity is considerably raised that reduces the mobility of ions of metal.…”

The possibility of the electroprecipitation of copper powder via the cathodic reduction of an electrolyte solution containing copper(II) nitrate trihydrate and dimethylsulfoxide (DMSO) is shown. The effect electrolysis conditions (current density, concentration and temperature of electrolyte) have on the dimensional characteristics of copper powder is studied. The size and shape of the particles of the powders were determined by means of electron microscopy; the qualitative composition of the powders, with thermogravimetric method.
