The 4-electron oxygen reduction reaction (ORR) under alkaline conditions is central to the development of non-noble metal-based hydrogen fuel cell technologies. However, the kinetics of ORR are constrained by scaling relations, where the adsorption free energy of *OOH is intrinsically linked to that of *OH with a nearly constant difference larger than the optimal value. In this study, a well-defined binuclear Co complex was synthesized and adsorbed onto carbon black, serving as a model dual-atom catalyst.

Global interest in lithium-sulfur batteries as one of the most promising energy storage technologies has been sparked by their low sulfur cathode cost, high gravimetric, volumetric energy densities, abundant resources, and environmental friendliness. However, their practical application is significantly impeded by several serious issues that arise at the cathode-electrolyte interface, such as interface structure degradation including the uneven deposition of LiS, unstable cathode-electrolyte interphase (CEI) layer and intermediate polysulfide shuttle effect. Thus, an optimized cathode-electrolyte interface along with optimized electrodes is required for overall improvement.

Background: Impaired cardiac function is associated with cognitive impairment and brain imaging features of aging. Cardiac arrhythmias, including atrial fibrillation, are implicated in clinical and subclinical brain injuries. Even in the absence of a clinical diagnosis, subclinical or prodromal substrates of arrhythmias, including an abnormally long or short P-wave duration (PWD), a measure associated with atrial abnormalities, have been associated with stroke and cognitive decline.

Sodium-ion batteries (SIBs) have captured widespread attention for grid-scale energy storage owing to the wide distribution and low cost of sodium resources. Delivery of high energy density with stable retention remains a challenge in developing cathode candidates for rechargeable SIBs. Inspired by the concept of "cationic potential", here, we present a hierarchical crystalline domain in hexagonal particles with target chemical composition (NaLiMgNiFeMnTiO) from the inner bulk O3 phase (71.

Hearing loss, a prevalent sensory impairment, poses significant challenges worldwide. Recent research has shed light on the intricate interplay between ferroptosis, a newly recognized form of regulated cell death characterized by iron-dependent lipid peroxidation, and oxidative stress in the pathogenesis of hearing loss. In this review, we delve into the mechanisms underlying ferroptosis and oxidative stress in various forms of hearing loss, including age-related hearing loss (ARHL), noise-induced hearing loss (NIHL) ototoxic drug-induced hearing loss and genetic hearing loss.

Autophagy functions as the primary cellular mechanism for clearing unwanted intracellular contents. Emerging evidence suggests that the selective elimination of intracellular organelles through autophagy, compared to the increased bulk autophagic flux, is crucial for the pathological progression of central nervous system (CNS) disorders. Notably, autophagic removal of mitochondria, known as mitophagy, is well-understood in an unhealthy brain.

  • High-voltage sodium metal batteries (SMBs) are promising for high-energy-density applications due to the cost and abundance of sodium, but they face challenges like capacity decay from electrolyte decomposition and safety issues from reactive components.
  • A new dual-anion aggregated sodium solvation structure in a nonflammable electrolyte is proposed, forming a stable cathode/electrolyte interphase that reduces unwanted reactions and enhances stability and sodium transport.
  • The NaNiFeMnTiO//Na batteries using this electrolyte achieved a discharge capacity of 167.5 mAh/g with 85.2% capacity retention over 800 cycles, showcasing a potential strategy for safer, high-voltage SMBs.

  • Previous studies indicate that fermented barley is digested more slowly, but the role of nonstarch components like protein, lipid, and β-glucan in this process needs clarification.
  • Removing these nonstarch components, particularly protein, significantly enhances the breakdown of starch during digestion, with protein showing the most substantial impact.
  • The study reveals that protein forms a physical barrier around starch, maintaining its structure and preventing swelling, which ultimately hinders starch hydrolysis.

Significant changes in brain morphology occur during the third trimester of gestation. The capability of deep learning in leveraging these morphological features has enhanced the accuracy of brain age predictions for this critical period. Yet, the opaque nature of deep learning techniques, often described as "black box" approaches, limits their interpretability, posing challenges in clinical applications.

New reactions of benzyl phosphine oxide/sulfide with oxalyl chloride are presented. The resulting reactive intermediates, acyl chloride-substituted chlorophosphonium ylides, are capable of undergoing esterification and Friedel-Crafts acylation reactions, ultimately yielding either methyl 2-(2-bromophenyl)-2-(diphenylphosphoryl)acetate or β-carbonyl-diarylphosphine oxide derivatives. Additionally, when an alkynyl group is contained in the acyl chloride-substituted chlorophosphonium ylide, intramolecular cyclization occurs, leading to the formation of a pair of and dichlorophosphonyl benzofulvene isomers.

Purpose: Studying perivascular spaces (PVSs) is important for understanding the pathogenesis and pathological changes of neurological disorders. Although some methods for automated segmentation of PVSs have been proposed, most of them were based on 7T MR images that were majorly acquired in healthy young people. Notably, 7T MR imaging is rarely used in clinical practice.

Building on research demonstrating the benefits of music training for emotional prosody recognition in nontonal languages, this study delves into its unexplored influence on tonal languages. In tonal languages, the acoustic similarity between lexical tones and music, along with the dual role of pitch in conveying lexical and affective meanings, create a unique interplay. We evaluated 72 participants, half of whom had extensive instrumental music training, with the other half serving as demographically matched controls.

Reverse electron transfer (RET), an abnormal backward flow of electrons from complexes III/IV to II/I of mitochondria, causes the overproduction of a reduced-type CoQ to boost downstream production of mitochondrial superoxide anions that leads to ischemia-reperfusion injury (IRI) to organs. Herein, we studied low-coordinated gold nanoclusters (AuNCs) with abundant oxygen-binding sites to form an electron-demanding trapper that allowed rapid capture of electrons to compensate for the CoQ/CoQH imbalance during RET. The AuNCs were composed of only eight gold atoms that formed a Cs-symmetrical configuration with all gold atoms exposed on the edge site.

Unlabelled: Infection with precipitates a spectrum of pathologies in bovines, notably necrotic pneumonia, mastitis, and arthritis, impinging upon the health and nutritional assimilation of these animals. A pivotal factor, lipocalin 2 (Lcn2), is responsive to microbial invasion, inflammatory processes, and tissue damage, the extent of which Lcn2 modulates the gut environment, however, remains unclear in response to -induced alterations. To explore the role of Lcn2 in shaping the gut milieu of mice during a 5-week period post infection, Lcn2 knockout Lcn2 mice were scrutinized for changes in the gut microbiota and metabolomic profiles.
