Balanced Iodophilicity and Solvophilicity Unlocks Fast Iodine Conversion Chemistry.

The shuttling of polyiodides and sluggish redox kinetics greatly hinder the implementation of an aqueous Zn-I battery. Despite numerous catalysts have been implemented to improve the iodine cathode stability, an important aspect, the balance between polyiodide adsorption and interfacial mass transport kinetics at the cathode surface, has been overlooked. It is known that insufficient intermediate trapping ability will cause low iodine utilization and fast capacity decay.

Deciphering SN2-Type Nucleophilic Substitution via Halogen-Free Intermediates for High-Energy Zinc-Iodine Batteries.

High-valence halogen conversion reactions are promising for realizing high-energy-density aqueous batteries. It has been more challenging to realize a stable and reversible / conversion than the facile / conversion. While interhalogen chemistry has been employed to realize a reversible /I/ (i.

A Synchronous Strategy to Zn-Iodine Battery by Polycationic Long-Chain Molecules.

Aqueous Zn-iodine batteries (ZIBs) face the formidable challenges towards practical implementation, including metal corrosion and rampant dendrite growth on the Zn anode side, and shuttle effect of polyiodide species from the cathode side. These challenges lead to poor cycle stability and severe self-discharge. From the fabrication and cost point of view, it is technologically more viable to deploy electrolyte engineering than electrode protection strategies.

Multimodal electrolyte architecting for static aqueous zinc-halogen batteries.

Rechargeable static aqueous zinc-halogen batteries (AZHBs) thrive in energy-storage applications due to their suitable redox potential, abundant reserves and relatively high energy density. This non-flow battery relies on the collaboration of the reversible stripping/plating process of Zn metal and the halogen-participating zincation reactions. However, the corrosion of Zn metal and the shuttling of the halogen species result in serious capacity decay, posing challenges to their reversibility and lifespan.

CMOS-Compatible Protonic Three-Terminal Memristor for Analog Synapse in Neuromorphic Computing.

All-solid-state inorganic hydrogen-based three-terminal memristors (H-3TMs) suffer from poor retention, susceptibility to humidity and temperature, and the reliance on wet chemistry during fabrication, hindering their manufacturability within existing foundry processes. To address these, this study presents a CMOS-compatible H-3TM based on reversible intercalation and extraction of protons between the SiN electrolyte and WO channel. The protons are introduced via a straightforward hydrogen plasma treatment, promoting a compatible fabrication process with back-end-of-line integration.

Oxygen-Doped MoS with Expanded Interlayer Spacing for Rapid and Stable Polysulfide Conversion.

Lithium-sulfur batteries face challenges such as the polysulfide shuttle effect and sluggish redox kinetics, leading to poor sulfur utilization and limited cyclic stability. Herein, an oxygen-doped engineering approach is presented to achieve pillar-free interlayer extension of MoS (E-MoS) for lithium polysulfide conversion. E-MoS features expanded interlayer spacing (from 0.

Colonoscopy-Related Adverse Events in the 21st Century: An Updated Systematic Review and Meta-Analysis.

Introduction: Colonoscopy is one of the most commonly performed endoscopic procedures and is generally considered low-risk. However, when adverse events (AEs) occur, they can present significant challenges in clinical practice. The aim of this study was to estimate the global incidence of colonoscopy-related AEs.

Glucagon-like peptide-1 receptor agonists increase the risk of residual gastric content and pulmonary aspiration on upper endoscopy: A meta-analysis.

Background And Aims: Glucagon-like peptide-1 receptor agonists (GLP1-RA) are associated with increased residual gastric content (RGC); however, there is debate about their impact on RGC-related clinical outcomes, particularly aspiration.

Methods: PubMed, Embase, Web of Science and Cochrane Library databases were systematically searched for studies published up to January 4, 2025, comparing GLP1-RA with control groups (non-GLP1-RA) in patients undergoing endoscopy. The outcomes of interest included the risk of RGC, pulmonary aspiration, interrupted and repeated endoscopic procedures, and delays in gastric transit time during capsule endoscopy.

Constructing a Graphene-like Layered Carbocatalyst by the Dual Templating Effect for an Efficient Fenton-like Reaction.

Two-dimensional (2D) carbon materials are receiving increasing attention due to their partly groundbreaking performance in catalysis and electrochemistry based on distinct physiochemical and textural properties. We focus on the challenge to directly achieve a well-developed layered morphology with a high doping level of heteroatoms as the active sites, a standard conflict of interests of high-temperature synthesis. Here, we report a dual-templating strategy to yield graphene-like layered carbon (GLC) by direct carbonization of a texturally prealigned zeolitic imidazolate framework-8 (ZIF-8).

Prevalence of colonoscopy-related adverse events in older adults aged over 65 years: a systematic review and meta-analysis.

Background: This study aims to assess the occurrence of colonoscopy-related adverse events (AEs) in adults aged over 65 years, as there has been a significant increase in the prevalence of colonoscopies among the elderly compared to two decades ago.

Methods: A comprehensive search was conducted on 3 June 2024, using the PubMed, Embase, and Cochrane Library databases. Meta-analyses were performed using the generalized linear-mixed model, and the results were presented as pooled rates with relevant 95% confidence intervals (CIs).

Nomogram as a novel predictive tool for postoperative pneumonia after endoscopic submucosal dissection for superficial esophageal carcinomas: a multicenter retrospective study.

Objectives: Adverse events, such as postoperative pneumonia, can occur in some patients after esophageal endoscopic submucosal dissection (ESD). However, few studies have investigated it. As such, we aimed to develop a nomogram to evaluate the progression of postoperative pneumonia after esophageal ESD.

The effect of cortisone on female zebrafish (Dania rerio): Reducing reproductive capacity and offspring survival rate.

Cortisone is a naturally occurring corticosteroid hormone known for its wide range of anti-inflammatory and immunosuppressive effects, and it is commonly found in various aquatic environments. Previous reports have shown that cortisone can have significant negative impacts on fish; however, its specific effects on fish reproduction have not been thoroughly investigated. In this study, female adult zebrafish were exposed to 0.

Early gastric composite tumor comprising signet-ring cell carcinoma and mucosa-associated lymphoid tissue lymphoma: A case report.

Background: Composite tumors are neoplasms comprising two distinct, yet intermingling, cell populations. This paper reports a rare phenomenon where early gastric signet-ring cell carcinoma (SRCC) and gastric mucosa-associated lymphoid tissue (MALT) lymphoma coexist within the same lesion.

Case Summary: A 40-year-old woman presented to the West China Hospital for examination, which revealed a whitish, shallow, and uneven mucosal lesion in the stomach.

Endoscopic morphology of gastric MALT lymphoma correlate with API2/MALT1 fusion and predict treatment response after helicobacter pylori eradication.

Background: The presence of API2/MALT1 fusion in gastric mucosa-associated lymphoid tissue (MALT) lymphoma predicts poor response to Helicobacter pylori (Hp) eradication therapy. This study aimed to assess the correlation between endoscopic morphology of MALT lymphoma and API2/MALT1 fusion and evaluate treatment response to Hp eradication based on morphological subtypes.

Metal-organic framework derived crystalline nanocarbon for Fenton-like reaction.

Nanoporous carbons with tailorable nanoscale texture and long-range ordered structure are promising candidates for energy, environmental and catalytic applications, while the current synthetic methods do not allow elaborate control of local structure. Here we report a salt-assisted strategy to obtain crystalline nanocarbon from direct carbonization of metal-organic frameworks (MOFs). The crystalline product maintains a highly ordered two-dimensional (2D) stacking mode and substantially differs from the traditional weakly ordered patterns of nanoporous carbons upon high-temperature pyrolysis.
