A novel amperometric biosensor based on immobilizing acetylcholinesterase on 3-carboxyphenylboronic/reduced graphene oxide–gold nanocomposites modified electrode was developed for the detection of organophosphorus and carbamate pesticides . Acetylcholinesterase was successfully immobilized on the electrode with relatively high activity by the specific binding between the boronic acid group of 3-carboxyphenylboronic and the glycosyl of acetylcholinesterase. The biosensor enjoyed good sensitivity owing to the excellent properties of gold nanoparticles and reduced graphene oxide , which promoted electron transfer reaction and enhanced the electrochemical response. Parameters affecting the biosensor response such as pH, applied potential, enzyme loading and inhibition time were optimized. Based on the inhibition of an organophosphorus insecticide on the enzymatic activity of AChE, organophosphorus and carbamate pesticides were determined with satisfactory results in the presence of acetylthiocholine chloride as a substrate. Moreover, the fabricated biosensor had good repeatability and high stability.

LASC catalyst synthesis process was carried out using iron metal (Fe) and its characterization properties were tested. There are five stages carried out, namely, the manufacture of the LASC Fe(DS)3 catalyst, lactic acid dehydration, polycondensation of lactic acid into l -lactic acid oligomers (OLLA), depolymerization of oligomers into l -lactide, and the ROP process to convert l -lactide into Polymers. l -lactic acid (PLLA). The analysis used is as follows, Karl-Fisher; Spectroscopy Fourier Transform Infrared (FTIR); and Nuclear Magnetic Resonance (HNMR); Gel Permeation Chromatography (GPC); Thermogravimetry Gravity Analysis (TGA) and X-Ray Diffraction (XRD). Based on the experimental results, the catalyst Fe(DS) 3 has a crystallinity value of 24% which indicates an amorphous nature and is easy to react. The value of the thermal stability of the catalyst is at 180 °C where the catalyst is able to process up to a temperature of 180 ° C. Each step of the ROP is validated by FTIR analysis which shows that the components of the group are in accordance with the expected product. The comparison of the crystallinity values of PLA produced with FeCl 3 and Fe(DS) 3 were 37.5 and 49%, respectively. Melting temperature (Tm) values are 111 and 107 ° C, respectively, Td values are 327 and 352 °C, and the resulting molecular weights are 23,720 and 20,232 g/mol. Based on the results obtained, it can be seen that the use of a LASC catalyst in the form of Fe(DS) 3 is more effective than without using a LASC catalyst.

Near-infrared (NIR) phosphor-converted light-emitting diodes (LEDs) are becoming an efficient and promising solution for high-power NIR light sources, which have shown a broad range of possible applications in the fields of agriculture, food analysis and biomedical diagnostics. However, there is a long-standing challenge to develop tunable and thermally stable NIR-emitting phosphors as luminescence converters in the design of low-cost, compact and high-efficiency NIR LEDs. Here, we report a tunable broadband NIR photoluminescence in Na3Sc2(PO4)3:Cr3+ phosphors via Ga3+ co-doping and explore their application in NIR LEDs. With the fine-tuning of the doping concentration of Ga3+ ions from 0 to 6%, the NIR luminescence of the obtained phosphor can be tuned from sharp line emission at 694 nm (2E → 4A2 transition of Cr3+) to broadband emission centered at 750 nm (4T2 → 4A2 transition of Cr3+) upon blue light excitation. In the meanwhile, the NIR emission intensity at 100 °C and 150 °C can retain ∼100% and ∼84% of the initial value at room temperature when the Ga3+ content is determined to be 6%, leading to thermally stable broadband NIR emission in the as-synthesized Na3Sc2(PO4)3:Cr3+,Ga3+ phosphors. The NIR LEDs constructed by combining the commercial blue LED chips with the optimized NIR phosphors can generate broadband emission in the wavelength range of 600–1000 nm and deliver ∼4 mW of NIR output power with a power conversion efficiency of 2.6% at a drive current of 60 mA. The potential of the fabricated NIR LEDs as a lighting source for night vision and vein imaging is also demonstrated. The outcomes here highlight promising potential for Na3Sc2(PO4)3:Cr3+,Ga3+ as phosphor-downconverted light emitters in the design of high-power NIR LED devices for practical applications.

Maleated glycidyl 3-pentadecenyl phenyl ether (M-GPPE) was synthesized from glycidyl 3-pentadecenyl phenyl ether (GPPE), a renewable derivative from cardanol, with maleic anhydride (MAH) by grafting copolymerization. The resulting M-GPPE was used as a functionalized plasticizer for a styrene–butadiene rubber (SBR)/carbon black (CB)/silica composite. The effects of M-GPPE on the development of the filler network, the extent of silica dispersion, the curing characteristics, and the mechanical performance of the composites were studied. Meanwhile, a comparative study was performed between M-GPPE and aromatic oil, a traditional plasticizer used in SBR filler formulations. Gel permeation chromatography and IR and 1 H-NMR analysis results confirmed the occurrence of the grafting reaction between GPPE and MAH and the potential structure of M-GPPE. The thermostability of GPPE was improved by grafting copolymerization with MAH, as shown by thermogravimetric analysis results. The presence of M-GPPE resulted in a shorter curing time and better aging properties in the SBR composite compared with GPPE. The mechanical properties, dynamic mechanical analysis, and transmission electron microscopy analysis showed that the maleate of GPPE could enhance the compatibility between SBR and silica, improve the dispersion of silica in SBR, and partially replace the aromatic oil in the SBR/CB/silica composite formulation. © 2014 Wiley Periodicals, Inc.

Near-infrared (NIR) spectroscopic technology has shown extensive application prospects. However, developing NIR phosphors with tunability and high thermal stability is a huge challenge. In this work, a highly promising phosphate compound, K3Ga2(PO4)3, has been successfully synthesized. When doped with Cr3+ ions, it is particularly noteworthy that Cr3+ exhibits highly efficient and thermally stable broadband NIR luminescence in the tetrahedral coordination environment. This unique property makes K3Ga2(PO4)3:Cr3+ a compelling candidate for advanced photonic applications. Therefore, studying the luminescent properties of Cr3+ rare earth ions doped into tetrahedral sites is of great significance. In the tetrahedral coordination environment of K3Ga2(PO4)3:Cr3+ ions exhibit broadband near-infrared emission spanning from 700 to 1100 nm (λem = 822 nm, FWHM = 124 nm) under 452 nm blue light excitation. Remarkably, the quantum efficiency reaches as high as 70.9%, demonstrating its exceptional potential for advanced photonic applications. In addition, the phosphors demonstrated exceptional thermal stability with near-zero thermal quenching. The NIR luminescence intensity at 373 K and 423 K retained 109.0% and 90.4% of its initial room-temperature value, respectively. This remarkable performance can be attributed to the material's ultra-wide band gap, and minimal electron–phonon coupling. The NIR pc-LED devices, fabricated by integrating the optimized K3Ga1.93(PO4)3:0.07Cr3+ phosphors with a blue LED chip (λex = 455 nm), achieved a near-infrared output power of 274 mW with a conversion efficiency of 5.42% under a driving current of 100 mA. Experimental results demonstrate that the fabricated NIR pc-LED exhibits significant potential for applications in night vision and vein imaging technologies. This study provides a strategic framework for designing high-performance NIR pc-LED devices, utilizing K3Ga2(PO4)3:Cr3+ as an efficient phosphor-converted light source, and offers valuable insights for practical implementation in advanced optical systems.

Alcoholic liver disease (ALD) is one of the most prevalent liver diseases worldwide. There are currently no FDA approved pharmacological therapies specifically designed to prevent or treat ALD. Targeted nutritional interventions offer a promising avenue for ALD management. Cyanidin-3-O-glucoside (C3G), a natural anthocyanin, has shown potential in mitigating alcoholic liver injury, but its therapeutic utility is limited by poor stability and inadequate liver targeting. Here, we report a galactosylated chitosan-modified nanoplatform for the encapsulation and hepatic targeted delivery of C3G. The fabricated nanonutriosomes (C3G@GC-NS) exhibited favorable physicochemical stability, biosafety, and enhanced C3G accumulation in the liver. In a mice model of alcoholic liver injury induced by 15-day ethanol feeding, oral administration of C3G@GC-NS at a dose of 150 mg /kg (C3G equivalent) daily significantly alleviated liver injury. C3G@GC-NS outperformed free C3G in ameliorating steatosis, inflammation, and metabolic dysfunction. Mechanistically, the nanotherapeutic activates the AMPK signaling pathway, regulates PPARα-driven lipid and ethanol metabolism, and restores alcohol-induced gut microbiota dysbiosis. This study presents a rationally designed nanoplatform that enhances the therapeutic efficacy of C3G through coordinated modulation of hepatic metabolism and the gut-liver axis, offering a novel strategy for the treatment of ALD.

Copper is one transition metal element, which plays important roles in nature and living organisms. Especially, when copper in the industrial process is released into biological chain, it can pose heavy metal pollution and seriously endangers human health. Recently, membrane materials for adsorbing Cu 2+ have received sufficient attention and made encouraging progress. However, due to the interference from some coexisting ions like Pb 2+ , Cd 2+ , Co 2+ , et al., how to achieve selective and efficient Cu 2+ adsorption holds certain research value. Herein, we synthesize a novel organic molecule based on quinolince-2-one-3-carbaldehyde dihydrorhodizidine (QDO), which contains active hydrogen atoms and heteroatoms. According to self-assembly interaction with important biological carrier chitosan, an adsorption membrane containing a large number of nano particles is constructed. By taking advantage of the rapid Cu 2+ binding property of organic molecules, the membrane can efficiently and quickly adsorb Cu 2+ in water solution. At pH = 6.5, the adsorption reaches equilibrium state within 150 min, and according to following the thermodynamics and kinetics model, maximum adsorption capacities of 214.4763 mg/g for Cu 2+ are confirmed. We conclude the adsorption process is primarily governed by homogeneous chemisorption. The absorption membrane provides potentially promising prospects for highly selective and effective Cu 2+ treatment.

NASICON-type solid electrolytes exhibit substantial potential for application in all-solid-state lithium metal batteries (ASSLMBs) with a high energy density, attributed to their broad electrochemical window, high ionic conductivity, and excellent air stability. Nevertheless, the practical application is severely limited by inadequate chemical stability upon interaction with lithium metal. To address this challenge, a multifunctional interlayer was developed to suppress the detrimental reaction between Li metal and Li 1.5 Al 0.5 Ge 1.5 (PO 4 ) 3 (LAGP). The interlayer exhibits outstanding interfacial compatibility and minimized interfacial This interlayer was fabricated through the in-situ solidification of poly(ethylene glycol) methyl ether acrylate with cerium trifluoride, combined with ionic liquid (named as PCEIL). The interlayer exhibits outstanding interfacial compatibility and minimized interfacial resistance, which enables the Li|PCEIL-LAGP-PCEIL|Li symmetric battery to achieve stable cycling over 1000 h at 0.1 mA cm −2 without short-circuiting. Additionally, this interlayer enables superior performance in Li|PCEIL-LAGP-PCEIL|LiFePO 4 cells, with a remarkable capacity retention of 96.5 % after 250 cycles at 0.2C, and an impressive average Coulombic efficiency of 99.8 %. Therefore, this work provides effective strategies to stabilize NASICON-type solid electrolytes and lithium metal, promoting the development of high-performance ASSLMBs.

Two new coordination polymers, namely, poly[[μ3-3-(1H-benzimidazol-2-yl)propionato]zinc(II)], [Zn(C10H8N2O2)]n, (1), and poly[bis[μ2-3-(1H-benzimidazol-2-yl)propionato]cadmium(II)], [Cd(C10H8N2O2)2]n, (2) have been synthesized from 3-(1H-benzoimidazol-2-yl)propanoic acid ligands through a mixed-ligand synthetic strategy under a solvothermal environment, and studied by single-crystal X-ray diffraction. Complex 1 crystallizes in the orthorhombic space group Pbca and features a two-dimensional structure formed by a binuclear Zn2O4 core. Complex 2, however, crystallizes in the monoclinic space group P21/c and forms a one-dimensional chain structure. The ZnII and CdII ions have different coordination numbers and the 3-(1H-benzoimidazol-2-yl)propanoate ligands display different coordination modes. The structures reported here show the importance of the selection of metal ions and suitable ligands.

In this work, Sr 0.5 Zr 2 (PO 4 ) 3 –high-entropy ( Ln 1/ n )PO 4 monazite dual-phase ceramics with n = 5, 6, and 7 were prepared by microwave-assisted sintering for high-level waste immobilization, where Ln 1/5 = (La, Nd, Sm, Eu, Gd) 1/5 , Ln 1/6 = (La, Nd, Sm, Eu, Gd, Dy) 1/6 , and Ln 1/7 = (La, Nd, Sm, Eu, Gd, Dy, Ho) 1/7 . After 28 days of leaching at pH 4.0, 6.2, and 10.0, the LR Sr and LR Ln-average values for the n = 5 samples were 10 −4 –10 −3 and ∼10 −6 g·m −2 ·d −1 , respectively. Both phases exhibited optimal chemical durability at pH 6.2, and Sr and Ln release mechanisms were pH-dependent. After 28 days of leaching in deionized water, the LR Sr and LR Ln-average values for the n = 5, 6, and 7 samples were 10 −4 –10 −3 and 10 −7 –10 −6 g·m −2 ·d −1 , respectively. Increasing configurational entropy in the high-entropy ( Ln 1/ n )PO 4 monazite phase indirectly reduced Sr release through phase-coupled effects, whereas average Ln release remained nearly unchanged.

Sepsis-induced acute kidney injury (AKI) is characterized by mitochondrial dysfunction and dysregulated inflammation, with a lack of effective therapies. Studies have found that down-regulation of Sirtuin 3 (Sirt3) expression in renal tubular epithelial cells is associated with mitochondrial imbalance, suggesting its potential as a therapeutic target. Based on this, the research team developed a targeted nanodelivery system: black phosphorus nanosheets loaded with a cortistatin agonist were encapsulated with macrophage membranes modified with (KKEEE)₃K peptides to specifically deliver Sirt3-activating components to the kidneys. This nanosystem demonstrated favorable stability and biocompatibility. Ex vivo experiments confirmed its ability to alleviate lipopolysaccharide-induced oxidative stress, apoptosis, and inflammation in HK-2 cells, while restoring mitochondrial function. Mechanistically, the nanomaterial regulates mitochondrial homeostasis by activating the Sirt3–YME1L1 deacetylation axis. This study provides a novel nano-therapeutic strategy for sepsis-induced AKI, combining targeting capability with metabolism regulation, and holds broad implications for the treatment of inflammatory organ damage.
