New-Concept Metal-Based Artificial SEI Film of Polyimide Anode Material in Dual-Ion Batteries.

Organic material polyimides (PI) are widely used in secondary batteries due to green safety, renewables, and structural designability. However, problems such as low conductivity and structural damage of polyimide electrode materials seriously limit its practical application. Herein, an innovative in situ modification method with CaCl is used to construct pure Al metal-based artificial SEI film on the surface of PI to improve the electrochemical performance of organic dual-ion batteries.

Core-Shell Spheroid Structure TiO/CdS Composites with Enhanced Photocathodic Protection Performance.

In order to improve the conversion and transmission efficiency of the photoelectron, core-shell spheroid structure titanium dioxide/cadmium sulfide (TiO/CdS) composites were synthesized as epoxy-based coating fillers using a simple hydrothermal method. The electrochemical performance of photocathodic protection for the epoxy-based composite coating was analyzed by coating it on the Q235 carbon steel surface. The results show that the epoxy-based composite coating possesses a significant photoelectrochemical property with a photocurrent density of 0.

Photopolymerization of Coating Materials for Protection against Carbon Steel Corrosion.

This work demonstrated a workable approach for the synthesis of a re-healing polyaniline-modified epoxy resin coating material via photopolymerization. The prepared coating material exhibited low water absorption, allowing it to be used as an anti-corrosion protective layer for carbon steel. First, graphene oxide (GO) was synthesized through the modified Hummers' method.

The electronic structure and interfacial contact with metallic borophene of monolayer ScSX (X = I, Br, and Cl).

Two-dimensional (2D) semiconductors with excellent electronic and optical properties provide a great prospect for the fundamental research and application for the next-generation devices. Exploring the contact properties between 2D semiconductors and metal electrodes for improving the performance of nanodevices is of utmost importance. Motivated by the successful synthesis of bulk ScSI experimentally in a recent work [A.

Design an Epoxy Coating with TiO/GO/PANI Nanocomposites for Enhancing Corrosion Resistance of Q235 Carbon Steel.

In this work, a ternary TiO/Graphene oxide/Polyaniline (TiO/GO/PANI) nanocomposite was synthesized by in situ oxidation and use as a filler on epoxy resin (TiO/GO/PANI/EP), a bifunctional in situ protective coating has been developed and reinforced the Q235 carbon steel protection against corrosion. The structure and optical properties of the obtained composites are characterized by XRD, FTIR, and UV-vis. Compared to bare TiO and bare Q235, the TiO/GO/PANI/EP coating exhibited prominent photoelectrochemical properties, such as the photocurrent density increased 0.
