Hydrogel microspheres encapsulating molecularly imprinted polymers (MIPs) are promising hybrid sorbents, due to several advantages of high selectivity, fast mass transfer efficiency, and simple collection. Thus, Janus single-hole hollow nanoparticles (J-HNPs) with the size of 550 ± 70 nm were firstly designed by anisotropic emulsion template, and then MIPs were grafted onto their inner surface through electron transfer atom transfer radical polymerization (ARGET ATRP). Then as-prepared J-HNPs-MIPs were loaded into hydrogel microspheres via polymerizable water-in-oil (W/O) emulsion droplets combining gelatin methacryloyl (GMA) as monomers, and then obtained J-HNPs-MIPs@Gel with the mean diameter of 2.0 µm was applied for effective and selective separation of 2′-deoxyadenosine (dA). Fast adsorption equilibrium of J-HNPs-MIPs@Gel for dA can be achieved within 40 min, thanks to the hydrogel matrix and single-hole hollow structure for enhancing diffusion. The maximum multi-layer adsorption capacity calculated according to the Freundlich model was 10.31 μmol g −1 at 298 K. The specific memory to the size, shape and functional groups of dA endowed excellent recognition ability, and 88% of the initial capacity after four consecutive adsorption-desorption cycles was maintained. In addition, J-HNPs-MIPs@Gel was expected to show great potential for the selective enrichment and analysis of target dA molecule in complex biological samples.

Due to low cost and low toxicity, manganese oxides have been extensively explored to reduce organic pollutants in wastewater via peroxymonosulfate (PMS) activation; but the development of manganese-based catalysts with facile synthesis process at low temperatures and high efficiency is still of significant practical interest. In this paper, a simple room temperature method has been successfully developed to synthesize cryptomelane-type manganese octahedral molecular sieves (OMS-2) from KMnO 4 and MnSO 4 in the presence of carbon nanotubes (CNTs). The redox reaction between amorphous manganese oxide and CNTs results the decrease of manganese valences and the formation of OMS-2 phase at a low temperature of 25 °C. The changes of synthesis time, temperature and CNTs dosage altered the characteristics of the prepared materials. Compared with CNTs, OMS-2 and other manganese oxides hybrids, the synthesized catalysts demonstrated a remarkable efficiency for PMS activation to degrade organic dyes and a superior reusability during ten successive cycles. Sulfate radicals were formed as the active species in the system from the oxidation of low valent Mn species by PMS. This study not only provides a simple method to synthesize OMS-2 at room temperature, but also improves the understanding of PMS activation on manganese-based catalysts for pollutants degradation.

In contrast with three-dimensional perovskites , their two-dimensional (2D) analogues have been demonstrated to effectively improve the moisture tolerance due to the hydrophobicity of the long-chain organic layers. However, the insulating property of the long-chain organic layers will deteriorate the charge transport properties of the materials, limiting their applications in photovoltaics and optoelectronics . Short-chain organic cation with less carbon atoms may be a good substitution for the preparation of 2D perovskites with superior environmental stability and optoelectronic properties. In this research, quasi-2D (C 3 H 7 NH 3 ) 2 (MA) n-1 Pb n Br 3n+1 perovskite nanocrystals with an average size smaller than 10 nm were synthesized by a one-pot method, showing tunable emissions in the range of 406–524 nm for n = 1∼∞, with corresponding band-gaps of 3.63–2.30 eV. Time-resolved photoluminescence (PL) decays show that (C 3 H 7 NH 3 ) 2 PbBr 4 has the shortest average PL lifetime of 4.4 ns with the fast decay process occupying weighting proportion of 87.3%. When the nominal perovskite layers increases up to 2–4, the average PL lifetime raises up to 10.1–41.7 ns, with the slow decay process taking up most weighting percentage of >70%. MAPbBr 3 possesses the longest PL lifetime of 151.2 ns. The perovskite nanocrystals were then attempted to modify with oleic acid or to embed in PMMA matrix in order to improve their environmental stability. Results show that the stability of oleic acid and PMMA encapsulated nanocrystals improves greatly in comparison with bare nanocrystals.

Hydrogen produced through self-powered water-splitting can effectively meet the demand for miniaturized devices. However, the design of an efficient catalyst that integrates a zinc-air battery (ZAB) with a water-splitting cell is crucial for the development of such devices. In this study, we synthesized Pt/Ni 3 (PO 4 ) 2 on nickel foam (NF) via a two-step process. The resulting Pt/Ni 3 (PO 4 ) 2 /NF exhibited significantly enhanced trifunctional properties (hydrogen evolution reaction, HER; oxygen evolution reaction, OER; oxygen reduction reaction, ORR) compared to the Ni 3 (PO 4 ) 2 /NF precursor. Additionally, the ZAB assembled using Pt/Ni 3 (PO 4 ) 2 /NF as the air-cathode demonstrated superior rechargeable performance compared to the Ni 3 (PO 4 ) 2 /NF-based counterpart. Moreover, when Pt/Ni 3 (PO 4 ) 2 /NF was directly used as both the cathode/anode for the water-splitting device and the air-cathode for the ZAB, the self-powered hydrolysis device exhibited excellent hydrogen production performance. Upon investigating the influence of in-situ decorated Pt nanoparticles, we found that these Pt nanoparticles: 1) facilitate the morphological reconstruction of Ni 3 (PO 4 ) 2 , thus increasing the electrochemical surface area of the catalyst; 2) lower the hydrogen adsorption free energy of Pt/Ni 3 (PO 4 ) 2 , and the associated OER theorical potential; 3) shift the d-band center of Pt/Ni 3 (PO 4 ) 2 closer to the Fermi level, ultimately enhancing its intrinsic catalytic activity. This work is expected to provide a foundation for experimental, theoretical, and practical applications of other Ni 3 (PO 4 ) 2 -based multifunctional materials.

Efficiently harnessing solar energy for hydrogen production remains a significant challenge, primarily dependent on the rational design of photocatalysts. In this work, an S-scheme heterojunction was constructed by integrating TiO 2 with a biphenyl-bridged covalent triazine framework (CTF-2). The extended π-conjugation in CTF-2 significantly enhances visible-light absorption and generates abundant delocalized electrons. The heterostructure was confirmed by characterizations, which revealed an increased specific surface area and enhanced redox capacity. Photoelectrochemical tests indicated a significant reduction in charge recombination, attributed to the newly formed Ti-N bonds that promote electron transfer from TiO 2 to CTF-2. The active species capture experiment and band structure analysis corroborated the S-scheme charge transfer route. The optimal 1.0 wt% CTF-2/TiO 2 achieved an H 2 evolution rate of 2.975 mmol·g -1 ·h -1 , 4.92 times higher than pristine TiO 2 , and retained 83% of its activity after five cycles. This study provides a practical approach to designing high-performance, stable heterostructures for solar energy conversion.

Owing to the natural abundance of sodium, sodium-ion batteries (SIBs) serve as a more cost-effective option compared with lithium-ion batteries (LIBs), while offering comparable energy storage capabilities. This study presents the compositional optimizations, structural characterizations, and electrochemical performance of a new mixed sodium (Na) superionic conductor (NASICON)-type polyanionic material, NaFe 2 PO 4 (SO 4 ) 2 (NFPS). Subsequently, the introduction of Ni 2+ doping serves to simultaneously improve the structural integrity and electronic conductivity of the material, leading to a collective enhancement of the sodium-ion diffusion channels. The Ni 2+ -incorporated phase, NaFe 1.92 Ni 0.08 PO 4 (SO 4 ) 2 , exhibits faster Na + diffusion, resulting in superior rate and cycling performance versus NFPS. After 80 cycles at 25 mA g −1 , NFPS-Ni 0.08 maintains a discharge capacity of 58.7 mA h g −1 , outperforming undoped NFPS by 20%.

Tin–air batteries (TABs) exhibit high safety and low cost, and are expected to be used in electric vehicles and portable electronic devices. However, challenges such as the irregular deposition of tin (Sn) particles on Sn anodes, surface passivation, and significant hydrogen evolution have hindered the development of high-performance TABs. To address these challenges, this study introduces quasi-solid TABs (QSTABs) with satisfactory high-temperature resistance. A conductive metal–organic framework (c-MOF), particularly Ni 3 (HITP) 2 , was synthesized and deposited onto the Sn anode surface. The porous structure of c-MOF increased the specific surface area of the Sn anode, improved electronic conductivity and facilitated the absorption and release of ions during charge and discharge cycling. Theoretical calculations revealed that Ni 3 (HITP) 2 provided more electron donor sites to coordinate with Sn 2+ and inhibited hydrogen release. Additionally, carboxymethyl cellulose (CMC) was incorporated into the organic gel polymer electrolytes (OGPEs) to significantly enhance their water retention, ensuring stable operation of QSTABs between 25 and 50 °C. Notably, QSTABs assembled with CMC-OGPE/Sn@Ni 3 (HITP) 2 exhibited a fine cycle life of over 200 cycles at 50 °C. The electronic c-MOF material effectively inhibited metal shedding and side reactions on the Sn anode. These findings provide valuable guidance for developing QSTABs with high-temperature resistance.

Smoking, a pivotal environmental risk factor, drives diseases including lung cancer through genetic and epigenetic alterations. While 2-Naphthylamine (2-NA), a tobacco-derived carcinogen, is established as a bladder carcinogen via DNA damage, its role in lung carcinogenesis remains mechanistically uncharacterized despite epidemiological associations. This study identifies bronchial epithelium as a direct target of 2-NA, demonstrating dose-dependent DNA damage in 16HBE cells (peak at 250 μM, 12 h; P < 0.05), accompanied by S-phase arrest, apoptosis, reduced proliferation, and reactive oxygen species (ROS) generation. 2-NA exposure upregulated the expression of circSHOC1, which is a circular RNA derived from the SHOC1 gene, in a dose-dependent manner. Functional assays revealed that circSHOC1 overexpression exacerbated 2-NA-induced DNA damage by enhancing ROS production and 8-hydroxy-2′-deoxyguanosine (8-OHdG) accumulation, whereas knockdown attenuated these effects. Mechanistically, circSHOC1 interacted with mitochondrial protein SLC25A3 (Solute Carrier Family 25 Member 3), a key oxidative stress regulator; SLC25A3 knockdown mitigated DNA damage ( P < 0.01), and co-transfection experiments confirmed SLC25A3 as a critical mediator of circSHOC1-driven genotoxicity. Collectively, this work provides the first experimental evidence that 2-NA induces bronchial epithelial DNA damage via a circSHOC1-SLC25A3-ROS axis, supporting a novel mechanism for tobacco-associated lung carcinogenesis and highlighting 2-NA as a potential pulmonary carcinogen.

NiFe-layered double hydroxides (NiFe LDHs) are regarded as outstanding electrocatalysts for the oxygen evolution reaction (OER), but the inherent charge transport limitations hinder their practical application. Herein, we developed a 3D hierarchical α-Co(OH) 2 /NiFe LDH/NF composite catalyst via a simple electrodeposition-hydrothermal method. The introduction of α-Co(OH) 2 enables interfacial electron modulation with NiFe LDH, driving electron transfer from Ni/Co sites to Fe centers via multi-pathway coupling channels (Ni–O–Fe, Ni–O–Co, Co–O–Fe). This electron redistribution creates an optimized coordination environment that promotes the formation of high-valence Ni and Co species, subsequently facilitating the in situ formation of highly active phases (γ-NiFeOOH and CoOOH) during the OER process. The derived γ-NiFeOOH provides superior intrinsic activity, while the coexisting. CoOOH significantly enhances charge transport due to its high electronic conductivity. As a result, the composite achieves an overpotential of only 285 mV at a current density of 500 mA cm −2 , outperforming both NiFe LDH (372 mV) and α-Co(OH) 2 (441 mV). Additionally, this catalyst shows an excellent long-term stability at 100 mA cm −2 for 120 h. This work demonstrates that interfacial electronic modulation offers a strategy for designing efficient and durable OER catalysts capable of operating at industrial current densities.

Aptamer-based sensors (aptasensors) have been extensively employed in biosensing and diagnostics. However, the broader application of aptasensors fabricated with DNA and RNA aptamers has been limited due to the intolerance of DNA and RNA to nucleases in biological fluids. A majority of sugar-modified nucleic acids, in particular 2’-F and 2’-OMe-modified nucleic acids, demonstrate a remarkable resistance to nuclease degradation and thus hold great potential in the development of more stable aptamers and aptasensors. In this work, employing enzymes including a laboratory-evolved polymerase for 2’-modified nucleic acids, we carried out systematic evolution of ligands by exponential enrichment (SELEX) experiments to obtain 2’-F/OMe-RNA aptamers for Bacillus cereus 5/B/6 metallo-β-lactamase (B. cereus 5/B/6 MBL), a crucial marker of many penicillin-resistant strains. Three aptamers composed of 2’-OMe-A, 2’-F-U, 2’-F-C, and 2’-OMe-G nucleotides (Apt-FUC1, Apt-FUC2, and Apt-FUC3) have been obtained and systematically characterized. All of them exhibited excellent target binding affinities, with equilibrium dissociation constant (Kd ) values of 95.9, 70.0, and 81.3 nM, and outstanding biological stability. Combining FAM-labeled Apt-FUC1, Apt-FUC2, and Apt-FUC3 with graphene oxide (GO), which could quench the fluorescence of FAM, we successfully constructed three sensitive and biologically stable 2’-F/OMe-RNA aptasensors for B. cereus 5/B/6 MBL, with the limit of detection (LOD) values of 0.38, 0.27, and 0.29 nM. Moreover, these three aptasensors all demonstrated good specificity for target detection in biological samples. This work has established a streamlined strategy for generating stable 2’-F/OMe-RNA aptamers and aptasensors, which should broaden the application of sugar-modified nucleic acids in biosensing and diagnostics.

Kiwifruit has extremely high nutritional value, but its rootstock strongly influences the physiology and metabolism of its scion fruit. Here, we evaluated the influence of a new kiwifruit rootstock, Actinidia valvata ′Zhongmikangzhen No. 2′, on the leaves and fruits of the scion A. deliciosa ′Zhongmi 2′. The leaf size, leaf mineral element contents, fruit size (single-fruit weight, longitudinal diameter and transverse diameter), and fruit quality traits (soluble sugar content, vitamin C content, total acidity and dry matter content) of ′Zhongmi 2′ grafted on ′Zhongmikangzhen No. 2′ (zk) and A. deliciosa seedling (zp) rootstock were measured at five fruit developmental stages (30, 60, 90, 120, and 150 days after flowering (DAF)). The zk fruits were significantly larger than those of zp and their leaves were also longer. The leaf length and width of the zk fruits was significantly greater than those of the zp fruits. The leaf contents of Cu, P and Mo significantly differed at 60, 120 and 120 DAF, respectively. The fruits of the two stock–scion combinations may presented different flavors. UPLC–MS/MS analysis of the fruit metabolome revealed 1697 differentially expressed metabolites. These metabolites, which were divided into multiple categories through KEGG analysis, indicated significant differences in fruit quality and resistance. Decanoic acid (decreased in zk-hard) and 9-oxononanoic acid (increased in zk-hard) may collectively affect fruit aroma. Moreover, α-linolenic acid and 12-oxo-phytodienoic acid (a precursor of jasmonic acid), both of which increase in zk-hard, contribute to increased nutritional value and are involved in the abiotic stress response, respectively. This study revealed the effects of different rootstock–scion combinations on fruit quality traits and leaf mineral elements and provides a basis for studying the mechanisms of rootstock–scion interactions.

The Myrica rubra pomace polyphenols (MRPP) were used to study their hypoglycemic effects and mechanisms using Type 2 diabetes (T2D) (db/db) mice as the model. The results showed that the oral administration of MRPP (low-dose myricitrin, 50 mg/kg BW by gavage; high-dose myricitrin, 250 mg/kg BW by gavage; and Myrica rubra pomace, 500 mg/kg BW by gavage) for 4 weeks significantly reduced fasting blood glucose, glycated serum protein, serum insulin, and insulin resistance index in mice, as well as the dyslipidemia in mice was improved. MRPP was able to improve the structural morphology of hepatocytes and pancreatic β-cells in diabetic mice. Its hypoglycemic mechanism may involve the upregulation of GLUT-4 and IRS-1 genes expression in the PI3K and AMPK signaling pathways, downregulation of GSK-3β, AMPK, PI3K, and AKT genes expression, and enhancement of the activity of enzymes related to glycogen synthesis and glucose metabolism. Research findings on 16S rRNA suggest that MRPP has the ability to alter the composition of the gut microbiota, impede the growth of harmful bacteria, and foster the growth of beneficial bacteria. Therefore, MRPP was capable of reshaping the specific gut microbial community and supporting its application as a novel supplement in functional foods for the treatment of T2D.
