Triethylamine (TEA), a typical kind of volatile organic compound, is widely used as an industrial solvent, which is a threat to environment and human health. In this paper, a novel In2O3 nanocube gas sensing material with high sensing performances was synthesized through a simple one-pot hydrothermal method. The gas sensing test results are satisfactory such that the single phase of In2O3 nanocubes even exhibits a quite higher response of 12-10 ppm of TEA at a lower temperature (180 °C) than many conventional In2O3-based complexes and maintains high consistency in morphology and stability after the consecutive tests of 2 months. This work provides a facile and quite effective gas sensing material for TEA gas monitoring with high sensitivity and stability and good selectivity at lower working temperature that can be prepared in batch and further used as templates.We investigated the effect of carboxymethyl cellulose (CMC) and the particulate fluorine/acrylate hybrid polymer (FAHP) on the flow behavior of LiFePO4-based cathode slurries as well as on electrical and mechanical properties of the corresponding dry layers. CMC dissolves in water and partly adsorbs on the active particles. Thus, it has a strong impact on particle dispersion and a critical CMC concentration distinguished by a minimum in yield stress and high shear viscosity is found, indicating an optimum state of particle dispersion. In contrast, the nanoparticulate FAHP binder has no effect on slurry rheology. The electrical conductivity of the dry layer exhibits a maximum at a CMC concentration corresponding to the minimum in slurry viscosity but monotonically decreases with increasing FAHP concentration. Adhesion to the current collector is provided by FAHP, and the line load in peel tests strongly increases with FAHP concentration, whereas CMC does not contribute to adhesion. The electrical conductivity and adhesion values obtained here excel reported values for similar aqueous LiFePO4-based cathode layers using alternative polymeric binders. this website Both CMC and FAHP contribute to the cohesive strength of the layers; the contribution of CMC, however, is stronger than that of FAHP despite its lower intrinsic mechanical strength. We attribute this to its impact on the cathode microstructure since high CMC concentrations result in a strong alignment of LiFePO4 particles, which yields superior cohesive strength.Hydrophilic materials are easily fouled by organic contaminants owing to their high surface energy, and this oil-fouling problem severely hinders their use in practical applications. To address this challenge, herein, a hydrophilic coating with oil repellency and photocatalytic activity is developed by a spray-casting process. In the air surrounding, a water droplet spreads over the coating surface completely, while oil droplets exhibit contact angles more than 150° and moving on the coating freely. The water-wetted coating still had oil repellency, as the water layer on the coating surface can act as a lubricant to repel oil. Although methylene blue aqueous solution contaminates the coating by wetting it completely, these water-soluble organic molecules can be removed by UV illumination, due to the photocatalytic activity of the coating. Exploiting its water-attracting and oil-repelling properties, the coating deposited on a copper mesh is applied as a multiplatform for oil-water separation with high separation efficiency. This study provides a novel and efficient way to solve the oil-fouling problem of hydrophilic materials.The objective of this study is to investigate the influence of the thyroid autoantibodies on the protein expression in follicular fluid and the clinical outcome of assisted reproductive technology. A total of 602 patients treated for infertility were screened; 49 euthyroid women who were positive for thyroid autoantibodies and 63 negative controls were recruited. Follicular fluid samples were analyzed using proteomics. Validation of target proteins in follicular fluid was performed by using parallel reaction monitoring. Differentially expressed proteins in follicular fluid, clinical pregnancy rate, abortion rate, and live-birth rate were analyzed. Clinical pregnancy rates and take-home baby rates in the thyroid autoimmunity (TAI) group were less than in the control group, but abortion rates in the TAI group were higher than in the control group (all P less then 0.005). A total of 49 proteins were differentially expressed in the TAI-positive group. In Gene Ontology secondary annotations of all the proteins identified, five types of proteins were associated with the reproductive process. Among 11 proteins quantitatively identified by parallel reaction monitoring, angiotensinogen and fetuin-B were associated with reproduction. These differentially expressed proteins identified in this study involved multiple pathways according to the Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis. Our study provides evidence that some differentially expressed proteins between TAI-positive women and controls were associated with the reproductive process and closely related to important physiologic effects, which could partially explain the underlying mechanism link between TAI and the adverse outcomes of assisted reproductive technology.The rapid spread of β-lactamase-producing bacteria in clinical practice has increasingly deteriorated the performance of β-lactam antibiotics against such resistant strains. Thus, novel agents or strategies for the war against β-lactamase-producing bacteria, especially hypervirulent resistant bacteria (such as toxin-secreting Staphylococcus aureus) carrying complex β-lactamases, are urgently needed. In this study, we found that the natural compound oleanolic acid (OA) and its analogues (especially corosolic acid (CA)) significantly inhibited the activity of important β-lactamases (NDM-1, KPC-2, and VIM-1) in Enterobacteriaceae and β-lactamases (β-lactamase N1) in S. aureus. The results showed significant synergy with β-lactams against β-lactamase-positive bacteria (fractional inhibitory concentration (FIC) index less then 0.5). Additionally, OA treatment significantly inhibited the activity of hemolysin from various bacteria. In the mouse infection models, the combined therapy with OA and β-lactams exhibited a significant synergistic effect in the treatment of β-lactamase-producing bacteria, as evidenced by the survival rate of S.
