Summary: This study proposes the use of Passerini three-component polymerization (P-3CP) to modify polyethylene glycol (PEG) for solid polymer electrolytes (SPEs). The introduction of side groups via P-3CP successfully suppresses the crystallinity of PEG and improves the ionic conductivity and lithium ion transport properties of the resulting polyesters.

Summary: The paper investigates the dissociation and anion mechanism for formaldehyde hydroformylation using DFT calculation and experimental study. It finds that HCHO insertion into the Rh-H bond is the rate-controlling step in the dissociation mechanism, while the nucleophilic addition of HCHO to the HOCH2-Rh species is more energetically favorable in the anion mechanism. The research also suggests that the strong electron-donating ligand could lead to higher reactivity in the anion mechanism, providing insights for improving selectivity in the reaction.

Summary: The study successfully synthesized Ru/Ni2P/NF nanocomposites with excellent electroactivity for both the hydrogen evolution reaction (HER) and ethylene glycol electro-oxidation reaction (EGEOR) in an alkaline solution. The introduction of Ru nanoparticles optimized the surface adsorption energy, constructed a synergistic catalysis interface, and improved the electrocatalytic performance of nickel phosphide nanosheets. The symmetric Ru/Ni2P/NF parallel to Ru/Ni2P/NF ethylene glycol electrolyzer only required a low electrolysis voltage of 1.14 V for hydrogen production, effectively eliminating the H2/O2 explosion risk and highlighting an energy-saving mode for electrochemical hydrogen production.

Summary: A facile one-pot ethyleneglycol-mediated solvothermal synthesis of orthorhombic Co2P with particle size around 20-30 nm was reported as an efficient catalyst for both HER and OER. Co2P showed low overpotentials and long-term stability in acidic and alkaline medium for HER, as well as an overpotential of 364 mV at 10 mA cm(-2) current density for OER. XPS analysis confirmed the formation of amorphous cobalt oxyhydroxide (CoOOH) as an intermediate during the OER process.

Summary: Highly efficient and low-cost Pt-Co/C-AB bimetallic cathode electrocatalysts were synthesized for hydrogen-based proton exchange membrane fuel cell (PEMFC) using three different types of solvent, namely, dimethyl sulphoxide (DMSO), dimethylformamide (DMF), and ethylene glycol (EG). The synthesized Pt-Co/C-EG electrocatalyst exhibited the highest power density of 19.61 mW/cm(2) at a room temperature of 33℃. The power density increased to 26.11 mW/cm(2) (133% increase) when the cell operating temperature was raised to 70℃. This research highlights the potential of Pt-Co/C-AB-EG as a commercial electrocatalyst for PEMFC cathode, with ethylene glycol identified as the best solvent for synthesis.

Summary: Networks are important for describing relationships between people, roads between cities, reactions between chemicals, and other interactions. Bipartiteness, dividing the network into two groups, can facilitate the study of the network's structure. We have developed an algorithm that can find a near-optimal bipartisation within a reasonable time frame and used it to uncover the hidden structure of the CSD cocrystal network.
