Investigation of the electrochemical behavior using cyclic voltammetry and detection of [Mn(2+)(thiophenyl-2-carboxylic acid)2 (triethanolamine)] with adsorptive stripping differential pulse voltammetry. The electrochemical behavior of a manganese(II) complex [Mn(2+)(thiophenyl-2-carboxylic acid)2(triethanolamine)] (A) was investigated using cyclic and differential pulse voltammetry in an acetate buffer of pH 4.6 at a carbon paste electrode. Further, an oxidation-reduction mechanism was proposed. Meanwhile, an adsorptive stripping differential pulse voltammetric method was developed for the determination of manganese(II) complex.

Creating durable, motion-compliant neural interfaces is crucial for accessing dynamic tissues under in vivo conditions and linking neural activity with behaviors. Utilizing the self-alignment of nano-fillers in a polymeric matrix under repetitive tension, here, we introduce conductive carbon nanotubes with high aspect ratios into semi-crystalline polyvinyl alcohol hydrogels, and create electrically anisotropic percolation pathways through cyclic stretching. The resulting anisotropic hydrogel fibers (diameter of 187 ± 13 µm) exhibit fatigue resistance (up to 20,000 cycles at 20% strain) with a stretchability of 64.

Meliorating the behavior deposition of lithium polysulfides (LiPS) is crucial for enhancing the electrochemical performance of sulfur cathodes, which could be implemented by the precise modulation on the catalytic host. Herein, heterostructure engineering is employed to tune up the catalytic capability of CeVO, by introducing CeO through a simple adjustment in the addition sequence of reactants. The formed CeVO/CeO heterostructure has been demonstrated to exhibit appropriate interaction strength with LiPS for accelerating the catalytic conversion process, as well as an engineered surface for inducing three dimensional (3D) LiS deposition, thereby endowing the corresponding sulfur cathodes with excellent electrochemical performance under harsh conditions.

The overexpression of Human Epidermal Growth Factor Receptor 2 (HER2) protein is specifically related to tumor cell proliferation in breast cancers. Its presence in biological serum samples indicates presence or progression of cancer, becoming a promise biomarker. However, their detection needs a simple and high accuracy platform.

Two-dimensional (2D) materials are highly valued for their unique properties and potential applications, as they can display exotic behaviors differing from those of their bulk forms. Research on elementary and binary solids has been making great progress recently, while synthesizing multi-component 2D materials experimentally remains a challenge, despite the possibility of greatly extending the number of members of the 2D realm. In this study, we synthesized ternary BiTeX (X = Cl, Br, I) nanosheets with high crystallinity through an electrochemical exfoliation method.
