Ethylene glycol (C₂H₆O₂), a toxic alcohol commonly found in automotive antifreeze, de-icing solutions, and industrial coolants, can cause severe toxicity when ingested. Due to its sweet taste, it is often consumed accidentally or intentionally, leading to life-threatening consequences such as metabolic acidosis, acute kidney injury (AKI), and mortality. Prompt diagnosis and early treatment with antidotes such as fomepizole or ethanol, combined with hemodialysis, are essential in preventing severe outcomes.

Ag-boosted hydroxyl adspecies generation and carbonyl intermediates release for Pt-Ag-catalyzed ethylene glycol electro-oxidation.

J Colloid Interface Sci

April 2025

College of Biological, Chemical Sciences and Engineering, Jiaxing University, Jiaxing, Zhejiang 314001, China. Electronic address:

Electro-reforming of organics such as alcohols into commodity chemicals and H powered by renewables is intriguing and prevailing with the remarkable renaissance of electrochemical technology. Integrating Pt/Pd with an auxiliary metal, metal oxide, and metal hydroxide are feasible strategies to design the desirable catalysts toward alcohols electro-oxidation reactions. These catalysts however have high affinity toward carbonyl intermediates that occupy and poison the active sites.

Acute kidney failure from ingestion of "wood bleach" beekeeping miticide.

Am J Emerg Med

November 2024

Minnesota Regional Poison Center, Hennepin Healthcare, University of Minnesota Medical School, Minneapolis, MN, United States of America.

Wood bleach is >95 % oxalic acid formulation used off-label as a miticide for Varroa mites by hobbyist beekeepers. Wood bleach (oxalic acid) ingestions are poorly documented in the medical literature. A 46-year-old man presented to the emergency department nauseated and vomiting after accidentally ingesting "bleach and grain ethanol intended for use in beekeeping.

A combined surface science/microreactor approach was applied to examine interface effects in ethylene hydrogenation on carbon-supported Ag, Au, and Cu nanoparticle catalysts. Turnover frequencies (TOFs) were substantially higher for supported catalysts than for (unsupported) polycrystalline metal foils, especially for Ag. Spark ablation of the corresponding metals on highly oriented pyrolytic graphite (HOPG) and carbon-coated grids yielded nanoparticles of around 3 nm size that were well-suited for characterization by X-ray photoelectron spectroscopy (XPS), high-resolution (scanning) transmission electron microscopy (HRTEM/STEM), and energy dispersive X-ray spectroscopy (EDX).
