17 × 10-15 F per cell in capacitance under AC frequencies of 100 kHz and 1 MHz, respectively. It also successfully monitored transient modulation of tight-junctions that collectively began to open in 30 minutes after the injection of 100 ng ml-1 TNF-α (a relaxation agent), reached maximum relaxation with a 12.6% increase in impedance value and a 12% decrease in capacitance in 60 minutes, and recovered back to its original junction status after 720 minutes, which confirmed the observation in animal models in the literature. Note that the opposite trends in impedance and capacitance allowed the in-air EIS sensor to distinguish cell population changes from tight junction modulation. It was concluded that the developed in-air EIS sensor in an in vitro platform can enable in situ and real-time monitoring of the population of the 'air-exposed' cells as well as the modulation of tight-junctions, which has not been demonstrated yet.This work presents a series of molecular dynamics simulations of argon adsorption on a silicon substrate with different lattice orientations. From the simulation results, the density profiles are discussed and the amount of adsorbed particles is obtained at different pressures. It is found that the solid surface orientation has a great influence on the density distributions and atomic arrangements near the surface. With the collected data, the thermal constants derived from the expression of zeta adsorption isotherms are determined. The calculated isotherms agree well with the simulation results. Also, from a microscopic point of view, the molecular insights show that the structures of the adsorbates are present as clusters with different numbers of particles. The size of the clusters changes with pressure. At a relatively small pressure ratio, most of the clusters consist of a single molecule. As the pressure ratio increases, larger sized clusters appear, forming various cluster-types. The molecular cluster distributions are closely consistent with the basic approximation of the zeta adsorption isotherm. Furthermore, the surface adsorption sites determined from molecular dynamics simulation show good agreement with that predicted by the zeta isotherm model, which reaffirms the effectiveness of the theoretical model. When the isotherm is extended to a pressure ratio greater than unity, a finite amount of adsorption is predicted and the wetting conditions are obtained. Affected by the solid surface orientations, the pressure ratio at wetting for the silicon substrate with the (111) surface plane is larger than those of the (100) and (110) surfaces, indicating that a higher subcooling is required for the wetting transition.Two-dimensional (2D) nanomaterials with grain boundary defects are attractive to researchers in many fields, such as energy conversion and storage, sensing, catalysis and biological medicine. In this work, a nanostructure of 2D Fe-doped NiO nanosheets (NiFexO) with grain boundary defects was designed and applied in the electrocatalytic oxygen evolution reaction. This nanomaterial was synthesized through a solvothermal strategy followed by a thermally driven conversion process. In general, NiFexO electrocatalysts were fabricated with gradual morphological variation depending on the atomic ratio of Ni Fe. It is surprising that the Fe content determines the electrocatalytic performance and the overpotential of water oxidation exhibits an inverted volcanic pattern. As expected, the as-prepared 2D NiFe0.1O nanosheets with grain boundary defects exhibit enhanced OER activity (274 mV@10 mA cm-2) compared with the oxide electrocatalyst reported in 1.0 M KOH owing to the advantages of abundant active sites. This work will shed light on the design and fabrication of novel-structured nanocatalysts.Quantitative proteomics generates large datasets with increasing depth and quantitative information.
