The oxygen evolution reaction (OER), a bottleneck in electrochemical water splitting, is fundamentally limited by a scaling relationship between the binding energies of key intermediates (OH* and OOH*), imposing a minimum theoretical overpotential of 0.37 eV. Breaking this scaling relationship is crucial for enhancing OER activity, yet effective strategies remain scarce.

In this study, we observed the effectiveness of CT angiography (CTA), matrix metalloproteinase-9 (MMP-9) and platelet-activating factor (PAF) in the assessment of ACS.
Methods: A total of 124 patients with ACS admitted to our hospital from June 2022 to March 2024 were enrolled as study subjects.
The development of selective ligands to target DNA G-quadruplexes (G4s) and i-motifs (iMs) has revealed their relevance in transcriptional regulation. However, most of these ligands are unable to target individual G4s or iMs in the genome, severely limiting their scope. Herein, we describe a new Approach to Target Exact Nucleic Acid alternative structures (ATENA) that relies on the chemical conjugation of established G4 and iM ligands to a catalytically inactive Cas9 protein (dCas9), enabling their individual targeting in living cells.

Direct hydrogenation of CO to high-value chemicals, especially aromatics, is an effective strategy for the alleviation of carbon emissions. Tremendous progress has been made in the direct conversion of CO into aromatics recently, but the highly selective synthesis of light aromatics (C-C) remains a huge challenge due to the complex role of Brønsted acid sites (BAS) and pore properties of zeolite in aromatic synthesis. Herein, a combination of the Na-modified ZnFeO and plate-like ZSM-5 (pZ5) with different b-axis thicknesses, which shows excellent performance for CO hydrogenation to light aromatics.

This study extends its application to a novel domain: insect (silkworm) recognition. However, unlike person or vehicle ReID, silkworm ReID presents unique challenges, such as the high similarity between individuals, arbitrary poses, and significant background noise.

Pulmonary arterial hypertension (PAH) is a severe disease characterized by significant pulmonary vascular remodeling and right ventricular dysfunction. Activated fibroblasts can induce collagen deposition around blood vessels, thereby promoting vascular hardening and PAH development. Fibroblast activation protein (FAP) is a proline-specific serine protease expressed in active fibroblasts that is closely associated with tissue remodeling, inflammation, fibrosis, tumor growth, and cellular proliferation.

With Cu/bisphosphine as a catalyst, two versatile functionalities (boryl and allyl) were installed on azetine with concomitant construction of two new stereogenic centers. This represents a rare demonstration of Cu-catalyzed asymmetric boryl alkylation of electron-rich olefins and C═C bonds in strained heterocycles.

To this end, we optimized a series of Co(II) α-N-heterocyclic thiosemicarbazone complexes to obtain a Co(II) complex (C3) with significant cytotoxicity against tumor cells through an investigation of their structure-activity relationships and then constructed a C3-Lip delivery system. results showed that, on the one hand, C3/C3-Lip effectively inhibits tumor growth with almost no toxic side effects; on the other hand, C3-Lip improves the therapeutic efficiency and targeting ability of C3.

Methanol steam reforming (MSR) represents a cost-effective method for hydrogen production. Structured catalysts, which exhibit strong resistance to frequent mechanical vibrations and suitability for on-board MSR, are somewhat complicated to fabricate. Herein, we synthesized and investigated copper-magnesium (Cu-Mg) mesh-type structured catalysts by a modified cycling chronopotentiometry method.

The increasing production and consumption of tea drinks has led to the generation of large amounts of discarded extracted tea residues. As a result, researchers have attempted to extract tea water-insoluble protein (TP) from discarded tea residues to produce food emulsifiers. Thus, in this study, high-internal-phase Pickering emulsions (HIPPEs) stabilized by TP were developed and characterized.

High-temperature pyrolysis is a primary method for synthesizing single-atom catalysts (SACs). However, this method accelerates the migration of metal atoms within the solid support, leading to low atom utilization. Herein, we report a novel top-down synthesis strategy wherein surface-sintered nickel sulfide (NiS) nanoparticles (NPs) are in situ atomized into single atoms, achieving confinement of the single-atom catalyst within the shell layer and synthesizing a high-performance single-atom catalyst.

Histone lysine lactylation (Kla) is a novel epigenetic modification that plays a crucial role in cellular processes driven by glycolysis and lactate production. However, the mechanisms of histone lactylation and its interaction with m6A RNA methylation during early embryonic development remain underexplored. This study systematically investigated the effects of oxygen levels-atmospheric oxygen (atmosO; 20% O) and physiological oxygen (physO; 5% O)-on hallmark events during early embryonic development, revealing that lactylation modification regulates early goat embryonic development through the m6A methyltransferase-like 3 (METTL3).
