Until now, despite much progress in the study of metal–organic gels (MOGs), modification transition-metal containing MOGs with noble metal nanoparticles (NPs) is far from fully developed. Herein, iron-based nanosheet hybrids gold NPs (AuNPs) immobilization were first synthesized by a facile situ grown strategy at ambient conditions. It found that as-prepared AuNPs/MOGs (Fe) exhibited enhanced mimicking peroxidase-like activity, making them endowed outstanding performance chemiluminescence...
Novel metal-organic gels (MOGs) consisting of iron (Fe3+) as the central ion and 1,10-phenanthroline-2,9-dicarboxylic acid (PDA) ligand were synthesized by a mild facile strategy. The Fe(III)-containing xerogels (Fe-MOXs), obtained after removing solvents in MOGs, found to exhibit outstanding performance catalysis luminol chemiluminescence (CL) for first time even absence extra oxidants such hydrogen peroxide. possible CL mechanism was discussed according electro/optical measurements,...
The lattice stability and phonon response of Ti3C2Tx MXene at high pressure are important for understanding its mechanical thermal properties fully. Here, we use in situ hydrostatic X-ray diffraction (XRD) Raman spectroscopy to study the deformation behavior MXene. XRD spectra indicate that no phase transformation occurs up 26.7 GPa. elastic constant along a parameter was calculated be 378 In obtained high-pressure, out-of-plane modes (A1g ~ 210, 504, 711 cm−1) exhibit monotonic blueshifts...
Epitaxial synthesis and properties of novel Co Mn-doped Ge magnetic semiconductors were studied. growth high quality films with doping concentrations has been stabilized by the use two dopants. The transport system exhibit T(C) large magnetoresistance effects that can be controlled systematically concentration. maximum achieved in semiconducting materials is approximately 270 K at a composition Co0.12Mn0.03Ge0.85.
To improve the performance of crop models for regional yield estimates, a particle filter (PF) was introduced to develop data assimilation strategy using Crop Environment Resource Synthesis (CERES)-Wheat model. Two experiments involving winter wheat estimations were conducted at field plot and on scale test feasibility PF-based analyze effects PF parameters spatiotemporal scales assimilating observations model assimilation. The significant improvements in estimation suggest that is feasible....
Highly active, stable, and cost-effective enzyme-mimicking nanomaterials (nanozymes) hold the potential to be an alternative replace natural enzymes for catalysis of enzyme-like reactions in various applications. Here, novel 3D ruthenium-based metal-organic gels (Ru-MOGs) with fibrillar network structures have been successfully synthesized using a facile one-step strategy at room temperature. Surprisingly, developed networked Ru-MOGs simultaneously possess intrinsic horseradish peroxidase...
Abstract A novel and sensitive fluorescence analysis platform was constructed for the detection of chlorogenic acid (CGA) using carbon dots (C‐dots) with prominent sensitivity selectivity. Excitation‐dependent emission C‐dots were fabricated citric l ‐histidine as precursors through an efficient one‐step hydrothermal treatment. The maximum excitation wavelength as‐synthesized 340 nm 414 nm, respectively. Moreover, as‐prepared displayed excellent water solubility good photostability. quantum...
Recently, metal–organic gels (MOGs) appear as a potential alternative to the well-known frameworks due easier and more straightforward shaping other unique features. However, modification of MOGs with noble metal nanoparticles is still in its infancy. On hand, developing multifunctional SERS substrate materials facile way remains great challenge. Herein, silver nanoparticles/metal–organic (AgNPs/MOGs) hybrid, novel dual functional SERS-active platform that both Raman signal molecule highly...
Direct flexoelectric effect was investigated in a non-ferroelectric composite (Bi1.5Zn0.5)(Zn0.5Nb1.5)O7/Ag (BZN/Ag) where the structure symmetry permits no macro-piezoelectricity. The coefficient of BZN/Ag approaches 0.17 μC/m at room temperature. This value is 3–4 orders magnitude higher than those common dielectrics. Our research confirms existence insulated materials except for ferroelectric relaxors.
Herein, N, S co-doped carbon quantum dots (N, S-CDs) with high absolute quantitative yield (Abs-QY) of 50.2% were produced by hydrothermal treatment food residue crayfish shells. A new detection method thiamphenicol (TAP) and its analogues was established discovering the obvious fluorescence response between TAP S-CDs, which achieved a wide linear range 20-300 μg·L-1 limit (LOD) 11.12 μg·L-1. This novel probe exhibited strong sensitivity shows rapid in complex matrices (overall time is less...
The production, transportation, deposition, and dissolution of carbonate profoundly form part the global carbon cycle affect amount distribution dissolved inorganic (DIC) alkalinity (ALK), which drive atmospheric CO2 changes during glacial/interglacial cycles. These processes may provide significant clues for better understanding mechanisms that control climate system.
