Higher stability of nanophase GdO-CeO upon 400 keV Kr ion irradiation over bulk: role of defect annealing across grain boundaries.

The concept of inert matrix fuel (IMF) has been proposed to utilize the energetic value of Pu and transmute minor actinides in nuclear reactors. In order to offset the initial reactivity of nuclear fuel, gadolinium (Gd) is employed as a burnable poison, owing to its high neutron absorption cross-section. To gain insights into the radiation stability and influence of grain boundaries on irradiation behaviour, 5 mol% Gd-doped ceria samples, sintered at varying temperatures, were subjected to irradiation using 400 Kr ions.

Department of Critical Care Medicine, The First Affiliated Hospital of Wannan Medical College (Yijishan Hospital of Wannan Medical College), Wuhu, Anhui, China.
Background: The purpose is to formulate a modified screening protocol for acute respiratory distress syndrome (ARDS) in patients with respiratory support based on saturation of pulse oximetry (SpO) and inspired oxygen concentration (FiO).
Methods: This prospective observational study was conducted from August to October 2020 at the Department of Critical Care Medicine of Yijishan Hospital Affiliated with Wannan Medical College. All patients admitted during the study period and required arterial blood gas analysis and electrocardiogram monitoring were included in this study.

Formaldehyde (FA) is a hazardous pollutant causing acute and chronic poisoning in humans. While plants provide a natural method of removing FA pollution, their ability to absorb and degrade FA is limited. To improve the ability of plants to degrade FA, we introduced the E.

Introduction: Veno-arterial extracorporeal membrane oxygenation is frequently considered and implemented to help manage patients with cardiogenic shock from acute poisoning. However, utilization of veno-venous extracorporeal membrane oxygenation in acutely poisoned patients is largely unknown.
Method: We conducted a retrospective study analyzing the epidemiologic, clinical characteristics and survival of acutely poisoned patients placed on veno-venous extracorporeal membrane oxygenation using the Extracorporeal Life Support Organization registry.
Isolated Metal Centers Activate Small Molecule Electrooxidation: Mechanisms and Applications.

Electrochemical oxidation of small molecules shows great promise to substitute oxygen evolution reaction (OER) or hydrogen oxidation reaction (HOR) to enhance reaction kinetics and reduce energy consumption, as well as produce high-valued chemicals or serve as fuels. For these oxidation reactions, high-valence metal sites generated at oxidative potentials are typically considered as active sites to trigger the oxidation process of small molecules. Isolated atom site catalysts (IASCs) have been developed as an ideal system to precisely regulate the oxidation state and coordination environment of single-metal centers, and thus optimize their catalytic property.
