Nitrogen-doped carbon nanotubes for CO 2 electroreduction (CO 2 ER) to CO usually perform a low reaction activity due to weak adsorption and high activation energy of CO 2 . Herein, 2-chloropyridine molecules (2-PyCl) as co-catalysts were grafted onto nitrogen-doped carbon nanotubes (NCNT) to prepare a composite electrocatalyst (PyCl-NCNT). The structural characterization and electrochemical tests confirmed that chlorine atoms in 2-PyCl synergized with pyridine molecules, substantially enhancing the CO 2 adsorption capacity, thereby accelerating the CO 2 ER rate. PyCl-NCNT achieved a CO faradaic efficiency (FE CO ) of 91.3% and a CO partial current density (j CO ) of -26.8 mA cm -2 at -1.2 V vs. RHE, maintaining a FE CO above 90% in a wide electrochemical potential window (-0.7 ∼ -1.2 V).

In this study, a series of novel Eu3+-activated NaLu(MoO4)2 (NLMO) red phosphors were synthesized for the first time using hydrothermal, sol–gel, and microemulsion methods with varying active agents. The properties of these phosphors, including phase purity, crystal structure, DFT calculations, morphology, luminescence characteristics, thermal stability, and internal quantum efficiency, were comprehensively characterized. The results indicate that the ethylenediaminetetraacetic acid disodium salt (EDTA-2Na)-assisted hydrothermal method is the most suitable approach for the preparation of the phosphor. This method yields phosphors with a regular morphology, outstanding luminescence performance, relatively good thermal stability, and significantly high internal quantum efficiency. The internal quantum efficiency reaches 96.45%, and the phosphor exhibits good thermal stability, with the emission intensity at 423 K remaining about 73% compared to the initial temperature. The CIE chromaticity coordinate of the NLMO/0.13Eu3+ sample (0.667, 0.333) is very close to the standard chromaticity coordinate value (0.670, 0.330) from the National Television Standards Committee (NTSC). Remarkably, the color purity of the NLMO:0.13Eu3+ phosphor is an impressive 97%. Furthermore, Tb3+ was cointroduced in the NLMO:0.13Eu3+ phosphor, and its positive effects are discussed. Ultimately, a warm white light-emitting diode (W-LED) was fabricated using the studied NLMO:0.13Eu3+ phosphor with a 394 nm near-ultraviolet-emitting LED chip as the excitation source. The W-LED exhibits excellent properties such as high color purity, excellent correlation color temperature, and high color rendering index. Considering all of the results, the NLMO/Eu3+ red phosphor obtained by the EDTA-2Na-assisted hydrothermal method is an ideal red component for W-LEDs in various lighting applications.

Developing a strategy for efficiently synthesizing borohydrides with high capacity and favorable reversibility is significant for promoting the development of next-generation energy materials. This work proposes a novel Mg(BH 4 ) 2 –TiNbNiCuO@graphene (Mg(BH 4 ) 2 –TiNbNiCuO@GR) high-entropy system, integrating nanoconfinement and catalytic strategies to significantly enhance the dehydrogenation kinetics and cycling stability of Mg(BH 4 ) 2 . TiNbNiCuO medium-entropy oxide (MEO) were synthesized in situ on a graphene carbon skeleton as catalyst (TiNbNiCuO@GR). Subsequently, Mg(BH 4 ) 2 was slowly infiltrated into the TiNbNiCuO@GR framework, which served as a carrier for nanoconfined Mg(BH 4 ) 2 , forming the Mg(BH 4 ) 2 –TiNbNiCuO@GR. It is demonstrated that the close contact between nanoconfined TiNbNiCuO MEO and Mg(BH 4 ) 2 creates abundant active sites, which facilitates electron transfer to improve dehydrogenation kinetics (dehydrogenation onset temperature at 63.5 °C) with a high capacity of 9.8 wt% H 2 . Notably, high-entropy effect and nanoconfinement boost the structure stability of TiNbNiCuO and prevent the agglomeration of Mg(BH 4 ) 2 , respectively, thereby jointly achieving an enhanced reversibility of the dehydrogenation kinetics, enabling a capacity retention of 81.5% after 10 cycles. The synergistic nanoconfinement-catalytic effect within the Mg(BH 4 ) 2 –TiNbNiCuO@GR offers new insights into the efficient dehydrogenation pathway of Mg-based borohydride systems.

Biomass materials as an abundant renewable resource could replace traditional fossil fuels and non-renewable materials, providing a new solution to achieve sustainable development. In this paper, Ce-modified Co(OH) 2 /Cu 2 O composite catalysts were prepared by an electrodeposition method, and the CoOOH/CuOOH dual active sites were successfully obtained through an electrochemical reconfiguration strategy, and the experimental results showed that the incorporation of Ce induced the formation of high-valent Co and Cu species, which improved the activity of electrocatalytic HMF oxidation. At 0.55 V vs Hg/HgO, the HMF conversion reached 100%, the FDCA yield was 95.04% and the Faraday efficiency was up to 98.47%. These results confirm the effectiveness of Ce-based non-precious metal catalysts in electrochemical reconstruction strategies and demonstrate their potential application in the high-value conversion of biomass derivatives. This finding not only provides a solid research basis for the development of highly efficient catalysts, but is also expected to promote the development of related technological fields.

Adsorption was found to be an acceptable treatment option to remove geosmin (GSM) and 2-methylisoborneol (2-MIB). It is meaningful to investigate the adsorption capacity of granular activated carbon (GAC) for the two algal odorants in water, and the influences of natural organic material (NOM) and particle size. The adsorption process was studied with the four isotherm models (Langmuir, Freundlich, Temkin, and modified Freundlich), four kinetic models (pseudo first-order, pseudo second-order, Elovich, and intra-particle), and thermodynamics. The results showed that the adsorption of both compounds could be best described by the modified Freundlich isotherm and pseudo second-order model, and the obtained thermodynamic parameters (changes in heat of adsorption, entropy, and Gibbs free energy) revealed that the adsorption was endothermic and spontaneous. Downsizing the particle size of GAC was effective for improving the adsorption capacity and rate. The concentrations of the two odorants could be reduced from 500 ng L −1 to less than 10 ng L −1 with the presence of NOM (<20 mg L −1 total organic carbon, TOC).

2-amino-6-bromobenzothiazole (ABBT) as an inhibitor of copper corrosion in 0.5 M H2SO4 solution was researched in this study using with electrochemical measurement, scanning electron microscope, atomic force microscope, and theoretical calculation. Polarization curves manifest that ABBT acts as a modest cathodic-type inhibitor with a maximum achievable inhibition efficiency of 94.6% at 1 mM. EIS test indicates that ABBT adsorb on the copper surface and form an adsorption film, which obeys Langmuir adsorption model. Furthermore, DFT calculation and molecular dynamics simulation were utilized to explore the mechanism of inhibition of ABBT.

Background: To study choroidal thickness (CT) in type 2 diabetes mellitus (DM2) patients with moderate diabetic retinopathy (DR) and to correlate with changes in retinal thickness (RT) with swept-source OCT (SS-OCT) compared to healthy subjects. Methods: Fifty-four DM2 patients with moderate DR without diabetic macular edema (DME) and 73 age-matched healthy subjects were evaluated using SS-OCT to measure changes in total RT and CT in the nine areas of the Early Treatment Diabetic Retinopathy Study (ETDRS) macular grid. Results: The mean age was 64.06 ± 11.98 years and 60.79 ± 8.62 years in the diabetic and control groups, respectively. Total RT showed statistically significant differences in the temporal inner area, with higher values in the DM2 group (p= 0.010). CT did not show differences between the groups. There was a significant negative correlation between RT and age in all of the outer ETDRS areas and a positive significant correlation in the central area for the DM2 group. There was also a negative significant correlation between CT and age in all of the ETDRS areas except for the inferior inner area. In the DM2 group, a negative correlation was observed between RT and CT in the central area (p= 0.039) and in both horizontal parafoveal areas (temporal inner,p= 0.028; nasal inner,p= 0.003). Conclusion: DM2 patients with moderate DR have no changes with regard to CT. Both CT and RT decreased with age in DM2, showing a negative correlation between these factors in the central and horizontal parafoveal areas of the ETDRS grid.

The efficacy of eight kinds of green leaf volatiles (GLVs) was investigated as potential natural antifungal agents against Aspergillus flavus in this study. Based on the in vitro assay, volatile phase inhibitory effects of the selected eight GLVs were consistently more effective on A. flavus growth than contact phase inhibitory effects, and ( E )-2-hexenal exhibited the highest efficacy as it could totally inhibited growth of A. flavus at concentrations of 0.032 μL/mL air and 1.6 μL/mL under vapor and contact conditions, respectively. Furthermore, results obtained from the in vivo assay demonstrated that ( E )-2-hexenal possessed potent fumigant activity in reducing A. flavus infection in stored peanut seeds, as it could completely inhibit colonization of A. flavus at 0.32 μL/mL air. Both in vitro and in vivo assay results provided convincing evidence that ( E )-2-hexenal, one of the GLVs that is naturally present in many plants, can potentially be used as a highly efficient and eco-friendly antifungal fumigant to protect peanut seeds from contamination of A. flavus during storage.

Hydrophobic charge-induction chromatography (HCIC) with 2-mercapto-1-methyl-imidazole (MMI) ligands shows promising results in antibody purification. In this study, competitive adsorption processes between bovine immunoglobulin G (IgG) and bovine serum albumin (BSA) were investigated with MMI resins. Adsorption isotherms of IgG, BSA and IgG/BSA mixtures at various mass ratios were measured, and the Langmuir-Freundlich model was used to fit the adsorption experimental data. The results indicated that IgG could be preferentially adsorbed by MMI resins, and MMI-B-4FF-100 resin with the pore size of 43.2 nm and the ligand density of 101 μmol/g gel showed the best adsorption selectivity of IgG over BSA. In addition, binding behaviors of IgG and BSA in column were studied with MMI-B-4FF-100 at various pH values, and the optimized separation conditions were obtained as loading at pH 7.0 and elution at pH 4.0. Furthermore, IgG was effectively separated from IgG/BSA protein mixtures with MMI-B-4FF-100. The purities of IgG monomer reached above 95%, and the recovery kept about 90%. The results indicated that MMI-B-4FF-100 with high ligand density and moderate pore size would be a promising HCIC resin for IgG purification.

Electrochemical conversion of metal hexacyanoferrates into their oxides or hydroxides was successfully achieved and reported using nickel hexacyanoferrates (Ni-HCF). Herein, a versatile strategy for such a conversion was explored by potential cycling Ni(OH) 2 nanoparticle film modified electrodes in K 3 [Fe(CN) 6 ] or K 4 [Fe(CN) 6 ] solution. The results show that K 3 [Fe(CN) 6 ] is more prone to the conversion from Ni(OH) 2 to Ni-HCF. Their composition , morphology, and structure were characterized by the techniques such as scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and UV–vis spectrometry . The reaction mechanism is tentatively given. This strategy is also suitable for the other metal hydroxides including rare earth hydroxides such as neodymium, samarium etc.

A series of mono- and binuclear Co(II) complexes ( Co1 – Co7 ) supported by quinoline-2-imidate ligands were synthesized and thoroughly characterized. Measured by single crystal X-ray crystallography, complexes Co1 and Co3 adopted distorted tetrahedral structures around the cobalt center. Upon activation by ethylaluminium sesquichloride (EASC), these cobalt complexes exhibited high catalytic activity and cis -1,4-selectivity towards 1,3-butadiene polymerization. The effects of ligand environment, polymerization temperature, and cocatalyst types on the polymerization were investigated in detail. Interestingly, the binuclear Co(II) complexes exhibited high thermal stability, and the polymer yields were up to 97.2% even at a high temperature of 70 °C.

In this paper, a variety of 1-aryl-4-hydroxy-1 H -pyrrol-2(5 H )-one derivatives bearing 1,3,4-oxadiazole moiety were designed and synthesized. Preliminary bioassays suggested that these compounds not only exhibited favorable antibacterial activity toward plant pathogenic bacteria including Xanthomonas oryzae pv. oryzae ( Xoo ), Ralstonia solanacearum ( R. solanacearum ), and Xanthomonas axonopodis pv. citri. ( Xac ), but also demonstrated certain curative and protective activities against Tobacco mosaic virus (TMV). Further studies revealed that compounds 8a and 8l exerted the best inhibition effect against Xoo with the half-maximal effective concentration (EC 50 ) values of 8.6 and 7.3 μg/mL, respectively, which were better than that of commercial agricultural antibacterial bismerthiazol (EC 50 = 92.6 μg/mL). Given the above results, this kind of compounds can be further studied and explored as alternative antibacterial agents.
