Summary: In this study, the effects of slurry particle size, shape, composition, and loading on the behavior of the iron (II/III) reaction were investigated using three different carbon powders dispersed in aqueous acidic electrolyte. The slurry of YP-50F carbon particles showed a significant increase in the reaction rate, but failed to attract the majority of the faradaic current from the stationary electrode due to its low conductivity. On the other hand, the slurries of the two graphitic carbons allowed the faradaic reaction to occur primarily on the mobile slurry instead of the stationary current collector, thanks to their higher electrical conductivity.

Summary: This study introduces a new method to enhance the performance of microelectrode arrays (MEAs) for electrophysiological studies of neuronal networks by integrating 3D nanowires (NWs) with MEAs. The integration increases the surface-to-volume ratio, allowing for subcellular interactions and high-resolution neuronal signal recording. Conductive polymer coatings, specifically poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS), are investigated to improve charge transfer capacity and biocompatibility. The results show that PEDOT-coated electrodes exhibit thickness-dependent improvements in stimulation and recording performances, offering new possibilities for studying neuronal activity at the sub-cellular level.

Summary: In this study, a highly interconnected 3D metallic Cu&CuAux matrix with low-tortuosity and ultrahigh porosity was fabricated. It can greatly enhance the transfer of Li+ and reduce the Li nucleation barrier during the Li deposition process. The unique 3D Cu&CuAux structure can also homogenize the electric field and Li-ion flux, as well as decrease the lithium-ion concentration gradient in Li anodes. As a result, the composite 3D Cu&CuAux-Li anodes exhibit ultrahigh cycle life and high rate capabilities. Full cells consisting of the 3D Cu&CuAux-Li anodes and LiFePO4 cathodes also demonstrate good performance and stable cycle life.

Summary: Electrochemistry plays a central role in various fields such as biology and energy science, and research involves experimental and theoretical techniques. Modeling and simulation methods like density functional theory and molecular dynamics are essential for understanding the structural and dynamic properties of systems. The polarization effects at the electrode/electrolyte interface are particularly important but difficult to accurately simulate. This study demonstrates how the Ewald summation method incorporates these electrostatic interactions, focusing on the formal setup for calculations with periodic boundary conditions in two dimensions, which differ from the more common three-dimensional case. The implementation is validated on simple systems and a well-known graphite electrode/room-temperature ionic liquid interface, and the capabilities of the software MetalWalls are showcased by studying the adsorption of a complex functionalized electrolyte on a graphite electrode.

Summary: This study prepared protective bilayer composite coatings based on polyetherimide (PEI) containing ZnO or CuO particles on mild steel (MS) using the sol-gel dip coating method. The morphology and composition of the coatings were confirmed by scanning electron microscopy (SEM), X-ray diffraction (XRD), and energy dispersive spectroscopy (EDS) analysis. Attenuated total reflectance (ATR) analysis showed that the presence of oxide particles did not affect the polymer structure, while water contact angle tests revealed that PEI-CuO exhibited hydrophobic behavior, while PEI-ZnO and PEI alone showed hydrophilic behavior. Electrochemical impedance spectroscopy (EIS) analysis demonstrated that the PEI-CuO coating had impedance values above 5 x 10(5) Omega.cm(2) after immersion in NaCl for 8 days, representing a protective efficiency greater than 99%.

Summary: The birnessite structure of MnO2 makes it a promising electrode material for energy storage devices, especially supercapacitors, due to its high theoretical capacitance and pseudocapacitive response. The effect of alkali cations on the structure of birnessite has been discussed, but their role in the charge storage mechanism is still controversial. This study reveals new aspects of the pseudocapacitive charge storage mechanism of birnessite and discusses the contribution of non-faradaic and faradaic reactions based on EIS analysis. It demonstrates the role of alkali ions intercalation in the interlayer structure of birnessite.

Summary: This study reports the enhanced electrochemical performance of a pH-sensitive co-polymer modified MnO2 electrode in aqueous pseudocapacitors. The conformation of the polymer is controlled by local pH changes at the electrode/electrolyte interface during electrochemical stress. The addition of the pH-sensitive polymer contributes to improved electrode integrity and lifetime. After 10 cycles of electrochemical stress, the MnO2/pH-sensitive polymer composite retains around 70% of its capacitance, contrasting with the catastrophic failure of the pristine MnO2 electrode under the same stress conditions.

Summary: This work investigates the growth of manganese oxide on stainless steel for pseudocapacitor electrodes using a one-step potentiostatic method. The microstructure of the electrode material and its capacitive response were analyzed through in situ ellipsometry and electrochemical impedance spectroscopy. The results reveal the formation of three layers during the potentiostatic synthesis of manganese oxide on stainless steel: thickening of the native oxide layer on the substrate, and the growth of two distinct layers of manganese oxide. The inner layer is slightly more compact and resistive, while the outer layer is more porous.
