“…Sn and Sn alloys in the powder form can be obtained by electrolysis from the aqueous [9,10,[14][15][16][17][18][19][20][21][22] and non-aqueous electrolytes [23,24], deep eutectic solvent (DES) [2,11,[25][26][27] and ionic liquids [28][29][30][31]. Various acidic and alkaline aqueous electrolytes, such as chloride [16], chloride-gluconate [14,15], sulfate-coumarin [10], chloride-citrate [16], chloridesulfate-gluconate [15], sulfate [17][18][19][20] and hydroxide [9] electrolytes are used for a production of tin powders of different surface morphology.…”

The formation of tin dendritic nanostructures by electrolysis from the alkaline electrolyte has been investigated. Morphology and structure of Sn dendrites produced applying both potentiostatic and galvanostatic regimes of the electrolysis are characterized by SEM and XRD, respectively. Depending on the applied cathodic potentials, three types of Sn dendrites were obtained: (a) needle-like and spear-like, (b) fern-like, and (c) stem-like dendrites. The very branchy dendrites with branches of the prismatic shape obtained by the galvanostatic regime of electrolysis represented a novel type of Sn dendrites, not previously reported in the literature. To explain the formation of various dendritic forms, correlation with the polarization characteristics for this electrodeposition system is considered. The needle-like and the spear-like dendrites represented monocrystals of (200),(400) preferred orientation, the fern-like dendrites exhibited the predominant (220),(440) preferred orientation, while in the stem-like particles Sn crystallites were oriented to a greater extent in the (440) crystal plane than in other planes. The galvanostatically synthesized Sn particles possessed the strong (200),(400) preferred orientation. The strong influence of parameters and regimes of electrodeposition on structural characteristics of Sn dendrites is explained by the fundamental laws of electrocrystallization taking into consideration the concept of slow-growing and fast-growing crystal planes.

“…Application of multiple regression analysis–response surface methodology (RSM)–was used as a statistical modeling technique employed in the study using quantitative data obtained from properly designed experiments to solve multivariable equations simultaneously . In literature, RSM has been successfully applied for electrodeposition processes, , whereas in the present paper, it is used for the electrochemically induced release process.…”

Novel biocompatible hybrid-material composed of iron-ion-cross-linked alginate with embedded protein molecules has been designed for the signal-triggered drug release. Electrochemically controlled oxidation of Fe(2+) ions in the presence of soluble natural alginate polymer and drug-mimicking protein (bovine serum albumin, BSA) results in the formation of an alginate-based thin-film cross-linked by Fe(3+) ions at the electrode interface with the entrapped protein. The electrochemically generated composite thin-film was characterized by electrochemistry and atomic force microscopy (AFM). Preliminary experiments demonstrated that the electrochemically controlled deposition of the protein-containing thin-film can be performed at microscale using scanning electrochemical microscopy (SECM) as the deposition tool producing polymer-patterned spots potentially containing various entrapped drugs. Application of reductive potentials on the modified electrode produced Fe(2+) cations which do not keep complexation with alginate, thus resulting in the electrochemically triggered thin-film dissolution and the protein release. Different experimental parameters, such as the film-deposition time, concentrations of compounds and applied potentials, were varied in order to demonstrate that the electrodepositon and electrodissolution of the alginate composite film can be tuned to the optimum performance. A statistical modeling technique was applied to find optimal conditions for the formation of the composite thin-film for the maximal encapsulation and release of the drug-mimicking protein at the lowest possible potential.

Cu-Sn alloy foams were produced by electrodeposition in a 0.5 M sulfuric acid solution using a porous polyurethane (PU) template. A thin seed layer of Ti/Ni was sputter-deposited on the PU template. The sulfuric acid solution contained 10 mM Cu and 1 mM Sn to electrodeposit Cu-Sn alloy under diffusion-controlled condition. The effect of the solution temperature on the chemical composition, microstructure, and electrical resistivity of Cu-Sn alloy foams was fundamentally investigated. Increasing the solution temperature has reduced cathodic overpotential for alloy reduction, resulting in improved reduction rate and deposition efficiency of Cu-Sn alloy. Thermal treatment for the removal of the PU template contributed to the microstructural recovery of as-electrodeposited Cu-Sn alloy. Electrical resistivity of Cu-Sn alloy foams was measured using a Ag-wired plastic holder. In recent years, a number of researches on the synthesis of metal foams have been performed particularly due to their outstanding properties such as high energy absorption capacity, large specific surface area, and low density. Alloy foams have also attracted more interest because pure metal foams have relatively weak mechanical strength. Open-cell Cu alloy foams are characterized by highly porous structure, moderate mechanical properties, and excellent thermal and electrical conductivities in comparison to pure Cu foam for industrial applications. For example, Cu alloy foams have been studied for electrodes of Li-ion batteries to prepare for the increased demand for rechargeable batteries of high performance and large capacity as there is the explosive rise in popularity of portable electronic devices and electric vehicles.12,13 Cu-Sn alloy foams were suggested especially for a component of Li-ion battery electrodes considering their high specific gravimetric capacity, large volume capacity, cycleability, and low cost. [14][15][16] However, fundamental researches on the synthesis method of CuSn alloy foams were not carried out sufficiently although some processes such as ball milling, sintering, and electrodeposition were previously proposed to prepare Cu-Sn alloy foams. [17][18][19] Preparation of open-cell Cu-Sn alloy foams by electrodeposition is more appropriate in respect that an electrolyte can be delivered through their open-cell structures with micro-pores. The control of the chemical composition, microstructure, and electrical property of Cu-Sn alloy foams is available by understanding process parameters in producing Cu-Sn alloy foams by electrodeposition. The parameters include the chemical composition, pH, temperature, and stirring rate of an electrolyte as well as applied current and potential.In this study, we propose an electrochemical deposition process in producing Cu-Sn alloy foams using a porous polyurethane (PU) template. The PU foam template was thermally decomposed after a Cu-Sn alloy layer was electrodeposited on its surface covered with a thin Ti/Ni seed layer. Low concentrations of Cu and Sn, and a large Cu/Sn molar ratio...
