N-doped WO anchored on porous carbon (N-WO/PNC) was synthesized as an efficient oxygen reduction catalyst. The N doping reduced the overpotential of WO during oxygen reduction. N-WO/PNC displayed a half-wave potential of 0.85 V. An N-WO/PNC-based zinc-air battery displayed a high power density of 209.7 mW cm.

Respiratory physiological changes post initiation of neurally adjusted ventilatory assist in preterm infants with evolving or established bronchopulmonary dysplasia.
Eur J Pediatr

To assess respiratory changes after neurally adjusted ventilatory assist (NAVA) initiation in preterm infants with evolving or established bronchopulmonary dysplasia (BPD). Premature infants born less than 32 weeks gestation with evolving or established BPD initiated on invasive or non-invasive (NIV) NAVA were included. Respiratory data: PCO and SpO₂/FiO₂ (S/F) ratio before and at 4, 24, 48 h post-NAVA initiation were collected.

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.

Herein, we demonstrate a two-in-one strategy for efficient neutral electrosynthesis of H2O2 via two-electron oxygen reduction reaction (2e-ORR), achieved by synergistically fine-modulating both the local microenvironment and electronic structure of indium (In) single atom (SA) sites. Through a series of finite elemental simulations and experimental analysis, we highlight the significant impact of phosphorous (P) doping on an optimized 2D mesoporous carbon carrier, which fosters a favorable microenvironment by improving the mass transfer and O2 enrichment, subsequently leading to an increased local pH levels. Consequently, an outstanding 2e-ORR performance is observed in neutral electrolytes, achieving over 95% selectivity for H2O2 across a broad voltage range of 0.

Mycofactocin is a redox cofactor essential for the alcohol metabolism of mycobacteria. While the biosynthesis of mycofactocin is well established, the gene , which encodes an oxidoreductase of the glucose-methanol-choline superfamily, remained functionally uncharacterized. Here, we show that MftG enzymes are almost exclusively found in genomes containing mycofactocin biosynthetic genes and are present in 75% of organisms harboring these genes.

Objective: The usage of doxorubicin (DOX), an antineoplastic drug that is frequently used for the cure of cancer, is restricted to maximal doses due to its cardiac toxicity. Reactive oxygen species produced by DOX result in lipid peroxidation and organ failure, ultimately resulting in cardiomyopathy. Due to its high polyphenol content, virgin rice bran oil (VRBO) is a diet nutritional supplement with a strong antioxidant.
