ZnO‐templated Ni‐based bifunctional catalyst for efficient anion exchange membrane water electrolysis

open access: yesJournal of the American Ceramic Society, EarlyView.
NiMoP and NiFe were sequentially electrodeposited onto a ZnO nanorod template, enhancing the surface area and hydrophilicity while creating abundant active sites for the hydrogen and oxygen evolution reactions (HER and OER). The catalyst exhibited low overpotentials of 132 mV for HER and 290 mV for OER at 100 mA cm−2.

Using X‐ray computed microtomography (μCT) to determine subsample‐specific cosmogenic noble gas production rates of E (enstatite) chondrites

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 3, Page 442-463, March 2025.
Abstract Cosmic ray exposure (CRE) ages provide information about the parent bodies and source regions of meteorite classes. Cosmogenic noble gases are often used to quantify exposure time scales ranging from tens of ka to hundreds of Ma. The production rate of cosmogenic noble gases is primarily controlled by a meteorite's chemical composition ...

Textural and compositional characteristics of metallic spherules in impact melt from Monturaqui crater, Chile

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 3, Page 646-662, March 2025.
Abstract Samples of impactite from the small (~350 m diameter) Monturaqui crater in northern Chile contain Fe‐Ni metallic spherules sourced from the iron meteorite impactor. Textural characterization and quantification were done using SEM and μCT data. Two textural types are distinguished, with different size distributions.

Delayed Zinc Phosphide Toxicosis in a Dog

open access: yesJournal of Veterinary Emergency and Critical Care, EarlyView.
ABSTRACT Objective Zinc phosphide is a widely used, commercial, non‐anticoagulant rodenticide. However, there is a lack of detailed information in veterinary literature regarding its toxic effects. The purpose of this case report is to provide a comprehensive description of toxicosis caused by zinc phosphide in a dog that underwent early ...

Unveiling Surface Species Formed on Ni‐Fe Spinel Oxides During the Oxygen Evolution Reaction at the Atomic Scale

open access: yesAdvanced Science, Volume 12, Issue 25, July 3, 2025.
≈1 nm thick amorphous layer with a higher oxygen concentration is formed on the surfaces of pristine P‐doped NiFe2O4 and activated NiFe2O4. Such surface layer is thought to significantly promote the charge transfer kinetics compared to the oxyhydroxide layer grown on Ni1.5Fe1.5O4 during the oxygen evolution reaction.
