Summary: In this paper, the well-known Savitzky-Golay filter is extended to three-dimensional triangular meshes for smoothing noisy measurement signals. The original idea of locally polynomial model fitting is naturally adapted for smoothing functions defined on irregular two-dimensional triangular meshes. The focus is on surfaces represented by three-dimensional triangular meshes, which are locally homeomorphic to the two-dimensional topological disk. The generalized filter is defined on the plane, and local embeddings are used to pair the points of the two-dimensional disk and the three-dimensional surface, allowing for fitting low-degree multidimensional polynomials and obtaining a similar continuous model. The method is applied for mesh smoothing and compared to other mesh smoothing methods.

Summary: Current EIS validation methods only determine the data quality of a whole impedance spectrum, while EIS data quality is often affected by undefined outliers. In this study, a workflow combining an outlier definition and various validation techniques was developed to automatically detect and remove outliers in EIS data. Evaluation on simulated and real EISs demonstrated that the workflow outperformed human validation and improved data quality for accurate circuit modeling.

Summary: Four types of as-received carbon black samples with different surface areas were tested as oxygen reduction catalysts in an alkaline environment. The onset potential, electron transfer number, and kinetic current density were selected as the main performance indicators. Despite having a smaller onset potential than Pt/C, the electron transfer number and kinetic current density of the carbon black samples reached similar values. The results demonstrated a linear dependence between the onset potential and electron transfer number and the surface area/porosity. The carbon black sample with the highest porosity exhibited excellent catalytic behavior due to its developed ultramicropores, which facilitated oxygen adsorption and further reduction.

Summary: Impregnation of highly porous carbon black and micro/mesoporous activated carbon with cobalt and nickel nitrates followed by heat treatment at 850 degrees C in nitrogen revealed significant differences in catalyst performance depending on the type of carbon used. The catalytic activity was found to be strongly influenced by surface chemistry, porosity, and the formation of Co3O4. Co3O4 formation on highly conductive carbon black resulted in excellent performance, while nickel metal nanoparticles promoted ORR when Co3O4 was not formed in sufficient quantity. The presence of small pores significantly enhanced ORR efficiency by promoting oxygen adsorption and electron transfer.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
