Summary: Numerous synthetic techniques have been developed for the fabrication of porous metal electrodes, with 3D printing being a promising and facile route. However, the current techniques have limitations in terms of resolution for tuning the pore distribution and diameter of electrode materials. This study introduces the use of laser-induced forward transfer (LIFT) process to 3D print metal voxels, resulting in a porous electrocatalytically active gold (Au) electrode film. The porous Au electrodes produced using LIFT showed a significant increase in the electrochemically active surface area, making it a promising method for printing ordered porous electrodes with high surface areas.

Summary: Electrochemical sensors are increasingly important in medicine, environmental monitoring, and industrial process control. However, their development faces challenges such as low target compound concentrations and complex analytical matrices. Mesoporous Thin Films (MTFs) have attracted great interest as electrode modifications due to their high surface area, uniform pore distribution, and electrochemical signal modulation possibilities. To fully exploit the advantages of MTFs, reproducible methods for sensitive and selective MTF-modified electrodes need to be developed, and mass and charge transport processes within the film and on the electrode need to be understood.

Summary: Potentiostatic anodization was used to synthesize nanostructured copper oxide/copper (CuxO/Cu, x=1,2) electrodes for sensitive non-enzymatic glucose detection. The CuO/Cu electrode exhibited a high sensitivity of 2954.38 mu A mM(-1) cm(-2) to glucose and a linear range of 0.1 mM to 1.3 mM at a catalytic potential of 0.55 V. The electrode showed a fast response time of less than 3 s with the addition of 0.1 mM glucose. The nanostructure of the electrode, achieved through anodization in 1M KOH solution at -100 mV, contributed to the efficient glucose catalytic oxidation process and could be controlled by adjusting the potential and electrolyte concentration during anodization.

Summary: Electrochemical pressure impedance spectroscopy (EPIS) analyzes the voltage response of a polymer electrolyte fuel cell (PEFC) as a function of an applied pressure signal in the frequency domain. The EPIS technique modulates the cathode pressure of a PEFC with a sinusoidal signal and monitors the cell voltage, allowing for the diagnosis of internal processes. Experimental studies have shown that EPIS signal is affected by pressure oscillation amplitude, load, oxygen concentration, oxygen stoichiometry, and cathode gas flow rate.

Summary: This study investigates the electrodeposition of platinum (Pt) nanoparticles (NPs) using chloride (Cl-) and bromide (Br-) ions as additives to tune the particle morphology and electrocatalytic activity. The addition of NaCl leads to larger urchin-like particles, while NaBr produces smaller, more uniform NPs dispersed across the substrate. Combining the two halide ion species improves surface coverage and size distribution of the NPs. Furthermore, applying a higher potential for nucleation followed by a lower potential for growth reduces particle size and increases surface coverage. Pt NPs electrodeposited in the presence of Br- exhibit the highest mass activity for the oxygen reduction reaction. Additionally, the inclusion of cetyltrimethylammonium chloride and cetyltrimethylammonium bromide during electrodeposition results in small NPs with higher mass activity due to the formation of porous nanostructures.
