Eu/Tb co-doped films with low concentration gold nanorods have been prepared using the solution process. The luminescence spectra investigations indicate that the introduction of nanorods can effectively enhance the energy transfer from Tb to Eu under excitation of 292 nm, because of the plasmonic coupling with excited Tb complex. Under excitation of 360 nm, the emission at 612 nm is enhanced, the enhancement factor increases and then decreases as the molar ratio of Tb and Eu increases. The luminescence enhancement is attributed to the metal enhanced luminescence resulting from plasmonic coupling with excited Eu complex. The dual effects of LSPR on energy transfer and emission enhancement are both observed. More details on the luminescence of Eu/Tb co-doped films with nanorods are demonstrated, which gain a deeper understanding of the interactions luminescent-particle and luminescent-luminescent. V.In this work, a smart analytical strategy that combines excitation-emission matrix (EEM) fluorescence detection with alternating trilinear decomposition (ATLD) algorithm was developed for fast, on-line and interference-free study on the photodegradation kinetics of aflatoxin B1 (AFB1) and aflatoxin G1 (AFG1) in rice and wheat under UV-Vis light (λ = 250-500 nm) treatment. With the aid of prominent “second-order advantage” of ATLD method, pure fluorescence signals of two targeted analytes can be directly resolved out from heavily overlapping spectral environment and accurately quantified even in the presence of unknown matrix interferences. Cereal samples in kinetic processing of photodegradation were detected without complex pretreatment steps except for a simple extraction using methanol/water solution (41, v/v), which solves the problem facing varied matrix interferences in the case of on-line monitoring of aflatoxins. The kinetic signals of analytes of interest were directly extracted regardless of varied matrix backgrounds of various cereals. The kinetic curves and degradation speeds of AFB1 and AFG1 can be estimated by resolved quantitative data, optimal radiation conditions including 365 nm wavelength and 35 J m-2 density were discussed for high-efficiency detoxification control of aflatoxins in rice and wheat. This strategy was promising to be as an alternative tool for eco-friendly photodegradation kinetic study of mycotoxins or other hazards in complex foodstuff matrixes. V.We previously demonstrated that collagen metabolism affects scleral mechanical properties and scleral remodeling. Scleral remodeling changes the mechanical strain on sclera and scleral fibroblasts. SCH 900776 order We postulated that mechanical strain changes affect collagen metabolism in scleral fibroblasts. To understand the differences in collagen metabolism in scleral fibroblasts related to mechanical strain changes, scleral fibroblasts were isolated and cultured under different mechanical strains using the FX-4000 system or were treated with the TGF-β1 and TGFBR1 inhibitor LY364947. The collagen metabolism-related gene expression levels were detected. The results showed that the appropriate (lower) mechanical strain improved collagen synthesis and reduced collagen decomposition. In contrast, higher mechanical strain reduced collagen synthesis and enhanced collagen decomposition, especially a sustained higher strain. Furthermore, the effect of a transitory higher strain was recoverable, and collagen metabolism in scleral fibroblasts was regulated by TGF-β1. These results suggested that mechanical strain mediates TGF-β1 expression to regulate collagen metabolism in scleral fibroblasts, thereby affect scleral tissue remodeling. Three materials including stainless steel woven mesh (SSM), nickel foam (NF) and carbon cloth (CC) were conducted as cathode in Cd(II)-reduced microbial electrolysis cells (MECs), respectively. By using electrode potential slope (EPS) method, the experimental open circuit potentials of three cathodes were similar, while the SSM cathode showed the smallest resistance (6 ± 1 mΩ m2), following by NF cathode (18 ± 2 mΩ m2) and CC cathode (32 ± 5 mΩ m2). These values were analyzed to predicte higher current density and more positive cathode potential in the MEC with SSM cathode under subsequent operating conditions. Electrochemical performance was more likely to be limited by current density than cathode potential. Accordingly, the MEC with SSM cathode obtained better system performance than that with other cathodes. This study further expands the application of EPS method that quantitatively evaluating and effectively selecting cathode materials for better system performance in Cd(II)-reduced MECs. Food waste (FW) and cow manure (CM) were co-digested to achieve a stable and high-rate of methane production. The start-up conditions (substrate mixing (FW/CM) ratio, substrate to inoculum ratio, and initial pH) were optimised, and the optimised parameters were experimentally confirmed by batch operation under mesophilic temperatures. To further verify the effects of start-up conditions on the long-term co-digestion process, a semi-continuous dynamic membrane bioreactor was operated for over 300 days with an FW/CM ratio of 2.5. Following the optimised operation scheme, the organic loading rate gradually increased to 11.9 g COD/L/d. Thus, stable anaerobic co-digestion was maintained at FW/CM ratio of 2.5, and a high CH4 production of 2.71 L CH4/L/d and CH4 yield of 441 mL CH4/g VS was achieved. In the long-term operation, the digestate pH was stable at approximately 8.4, which indicated a very favourable anaerobic reaction condition without volatile fatty acid accumulation. Humic acid (HA) was applied as the biosorbent for the adsorption and degradation of dyes in the presence of environmentally persistent free radicals (EPFRs). Scanning Electron Microscope (SEM) analysis showed that the microstructure of the HA surface and the thermal stability was analyzed by thermogravimetric analysis (TGA). Following irradiation, semiquinone EPFRs (g-factor > 2.0045) were generated on the HA surface. Both O2 and the addition of H2O2 were able to promote the generation of hydroxyl and superoxide radicals for the degradation of dye in aqueous solution. Furthermore, adsorption was observed to remove large amounts of the dyes, while the instantaneous free radical degradation process reduced the dyes to the lower concentration. In addition, a linear relationship was observed between the consumption of EPFRs and dye degradation rates. In ternary systems, HA conformed to Langmuir (476.19-1250.12 mg/L) and pseudo-second-order kinetic models. This work offers new insights into HA-EPFRs and their potential applications.
