Local Electrochemical Measurements by 3D Printed Sf-MDC Equipped with Optical Microscope

“…Without this support structure, Sf-MDC with coaxial dual capillaries cannot be printed accurately. Since the fabricated Sf-MDC is affected by the printing direction and the resolution of the 3D printer, 25,26 the fine structure (inner capillary, solution inlet tube etc) was inspected carefully during the manufacture. After confirming that the structure is printed properly, the Sf-MDC was washed in 2-propanol and allowed to cure for 30 min.…”

“…The solution inlet was connected to a pump by a silicone tube (diameter; 2 mm) and the solution outlet was connected to an aspirator (ULVAC KIKO Inc., MDA-015). 25 The flow rate of the solution was controlled at 1.0 × 10 -3 cm 3 s −1 using a pump (ATTO Corp., SJ-1211), and aspirated at around 90 kPa with an aspirator. The solution was 10 mol m −3 NaCl.…”

“…24 Bilal et al performed area selective aluminum anodization and nickel/copper electrodeposition using a Sf-MDC fabricated by a 3D printer. [25][26][27] In addition, the conventional Sf-MDC is long in the vertical direction, with the result that it is difficult to equip it to a microscope, and it is difficult to precisely control the measured area. In this paper, a novel configuration of an Sf-MDC was fabricated using a 3D printer, equipped with an optical microscope, and local electrochemical measurements were performed to investigate the size of the Si related precipitates on the electrochemical behavior of an aluminum alloy.…”

Small-Area Techniques for Micro- and Nanoelectrochemical Characterization: A Review

“…No matter how the MCC technique progresses, its basic configuration is similar. The capillary tip made of glass is usually fabricated by laser/heat-assisted pulling, − and that made of organic materials is created by high-precision machining or 3D-printing techniques. − As for organic materials, with either the machining or the 3D-printing method, higher fabrication accuracy is necessary to reduce the tip diameter for higher spatial resolution. , In fact, the current resolution of the potentiostat, not the tip diameter of the microcapillary, is what determines the minimum lateral resolution. , The improved current resolution (<1 fA) allows the electrochemical tests to be performed on an exposed area even below 1 μm…”

High throughput electrochemically driven metal microprinting with multicapillary droplet cell

“…Robust, reproducible and cost-effective fabrication of metals at micrometer scale would enable rapid development of advance electronic devices, microelectromechanical systems (MEMS) and biomedical devices [1][2][3][4][5][6]. Conventionally, mask-based lithography is the main standard of industries to produce micro-or nano-scale patterns.…”
