Flame-retardant phosphate-based electrolytes effectively enhance lithium-ion battery safety but suffer from poor compatibility with graphite anodes and high-voltage cathodes, hindering scalability. Fluorinated phosphates, though widely used, increase interfacial resistance at the anode, degrading performance. In this work, carbonate solvents with strong polarity are introduced to prevent tris(2,2,2-trifluoroethyl) phosphate (TFEP) from participating in the solvation structure of lithium ions.

Solid-state polyether electrolytes formed by in-situ ring-opening polymerization (ROP) of 1,3-dioxolane (DOL) have attracted great attention due to their high lithium-ion conductivity, and good interface compatibility. However, DOL ring-opening polymerization is difficult to control, resulting in the formation of poly(1,3-dioxolane) (PDOL) with high molecular weight and high crystallinity, which hinder Li diffusion and deteriorate the interfacial contact. Herein, trimethylsilyl isocyanate (IPTS) was introduced into DOL ring-opening system as a moisture eliminating agent to weaken the Li salt-based initiating system and regulate the polymerization process.

Lithium-sulfur (Li-S) batteries have been pursued due to their high theoretical energy density and superb cost-effectiveness. However, the dissolution-conversion mechanism of sulfur inevitably leads to shuttle effects and interface passivation issues, which impede Li-S battery practical application. Herein, the approach of adopting transition metal salts (CoI) to engineering the electrolyte is proposed.

Eight previously undescribed solanapyrone analogues, sphasolanapyrones A-H (1-8), together with four structurally related known compounds (9-12) were obtained from the solid fermentation of Nigrospora sphaerica MZW-A, an endophytic fungus isolated from the fresh branches of the endangered conifer Pinus wangii. This study represents the first investigation on the secondary metabolites of endophytic fungus associated with this precious plant. The structures and absolute configurations of compounds 1-8 were elucidated by extensive spectroscopic analysis and electronic circular dichroism (ECD) calculations.

  • Working memory issues in ADHD are linked to abnormal connections in the brain's cortical functional networks (CFNC) among various regions like the frontal and temporal cortices.
  • Low-intensity transcranial ultrasound stimulation (TUS) has potential to improve memory behavior in ADHD due to its non-invasive and high-resolution nature.
  • The study found that TUS enhances working memory in ADHD rats by improving how information is transmitted and processed in the CFNC, revealing important mechanisms for addressing working memory impairments in ADHD.

Purpose: While copper (Cu) is essential for biological organisms, excessive Cu can be harmful. Ferroptosis is a programmed cell death pathway, but the role of ferroptosis in renal injury induced by Cu is limited. The aim of this study was to investigate the role of ferroptosis in kidney injury in chickens and the molecular mechanism by which Cu promotes renal ferroptosis.

Copper (Cu) is a common trace element additive in animal and human foods, and excessive intake of Cu has been shown to cause hepatotoxicity, but the underlying mechanism remains unclear. Our previous research found that Cu exposure dramatically upregulated mitochondrial miR-12294-5p expression and confirmed its targeted inhibition of CISD1 expression in chicken hepatocytes. Thus, we aimed to explore the potential role of mitomiR-12294-5p/CISD1 axis in Cu exposure-resulted hepatotoxicity.

"Polymer-in-ceramic" (PIC) electrolytes are widely investigated for all-solid-state batteries (ASSBs) due to their good thermal stability and mechanical performance. However, achieving fast and diversified lithium-ion transport inside the PIC electrolyte and uniform Li deposition at the electrolyte/Li anode interface simultaneously remains a challenge. Besides, the effect of ceramic particle size on Li transport and Li anodic compatibility is still unclear, which is essential for revealing the enhanced mechanism of the performance for PIC electrolytes.

Prior investigations have established that the manipulation of neural activity has the potential to influence both rapid eye movement and non-rapid eye movement sleep. Low-intensity retinal ultrasound stimulation has shown effectiveness in the modulation of neural activity. Nevertheless, the specific effects of retinal ultrasound stimulation on rapid eye movement and non-rapid eye movement sleep, as well as its potential to enhance overall sleep quality, remain to be elucidated.

Li-rich layered oxides cathodes (LLOs) have prevailed as the promising high-energy-density cathode materials due to their distinctive anionic redox chemistry. However, uncontrollable anionic redox process usually leads to structural deterioration and electrochemical degradation. Herein, a Mo/Cl co-doping strategy is proposed to regulate the relative position of energy band for modulating the anionic redox chemistry and strengthening the structural stability of Co-free LiMnNiO cathodes.

  • * The research confirmed that the E3 ligases CHIP and E4B ubiquitinated five specific substrates and showed that swapping the U-box domains between these ligases reduced their ubiquitination effectiveness.
  • * The study found that while different E3 ligases can use the same E2 enzymes for ubiquitination, the U-box domains primarily influenced E2 recruitment, emphasizing the importance of both the substrate and U-box domains in this process.

Peptide stapling is recognized as an effective strategy for improving the proteolytic stability and cell permeability of peptides. In this study, we present a novel approach for the site-selective unsymmetric perfluoroaryl stapling of Ser and Cys residues in unprotected peptides. The stapling reaction proceeds smoothly under very mild conditions, exhibiting a remarkably rapid reaction rate.

Lithium-sulfur (Li-S) batteries are a strong contender for the new-generation battery system to meet the growing energy demand due to their significantly high energy density (2600 Wh/kg) and cost-effectiveness. However, the practical operating conditions yield an initial capacity of less than 80 % of the theoretical capacity, resulting in a limited lifespan and hindering broader application. What's worse, current mechanism, especially the evolution process of sulfides for the initial capacity degradation is not clear due to the practical difficulties of effective separation and detection of sulfur-containing components.

The protein kinase RNA-like endoplasmic reticulum kinase (PERK)-eukaryotic translation initiation factor 2 subunit α (eIF2α) pathway plays an essential role in endoplasmic reticulum (ER) stress. When the PERK-eIF2α pathway is activated, PERK phosphorylates eIF2α (p-eIF2α) at Ser51 and quenches global protein synthesis. In this study, we verified eIF2α as a bona fide substrate of the E3 ubiquitin ligase carboxyl terminus of the HSC70-interaction protein (CHIP) both in vitro and in cells.

Article Synopsis
  • - Alzheimer’s disease is a complex neurodegenerative condition, with recent studies indicating that ferroptosis, a type of iron-dependent cell death, plays a role in the death of nerve cells in this disease, and frataxin (FXN) is a key protein regulating this process.
  • - In experiments with human neuroblastoma cells injured by L-glutamate, researchers found that overexpression of FXN improved mitochondrial function and morphology, which had previously deteriorated due to iron-related stress.
  • - The study shows a potential mechanism where reduced FXN expression contributes to mitochondrial impairment and ferroptosis in Alzheimer’s, suggesting that targeting FXN could offer therapeutic benefits.

Unlabelled: Epithelial-mesenchymal transition (EMT) is a fundamental cellular process frequently hijacked by cancer cells to promote tumor progression, especially metastasis. EMT is orchestrated by a complex molecular network acting at different layers of gene regulation. In addition to transcriptional regulation, posttranscriptional mechanisms may also play a role in EMT.
