Summary: The application of biological methods in industrial saline wastewater treatment is limited due to the inhibitory effect of highly concentrated salts on microbial activity. Acclimatized halotolerant and halophilic microorganisms play a key role in resisting high salinity. Electrical stimulation has been shown to enhance microbial salt tolerance and pollutant removal ability, but a comprehensive understanding of the underlying mechanisms is lacking.

Summary: In this study, machinability tests were conducted on a corrosion-resistant superalloy using electrical discharge machining (EDM) and the effect of different cryogenic treatments on the EDM processing performance was investigated. The optimal parameters for both surface roughness and material removal rate were determined using the Taguchi L-18 method. The results showed that peak current was the most significant factor affecting surface roughness and material removal rate.

Summary: Mesoscale periodic structures observed in solar wind plasma can serve as a diagnostic tool for understanding the formation of the solar wind. Analysis of four events with such structures reveals variations in elemental abundance, mass dependencies, and charge state, which are linked to temporal or spatial variations in solar source regions and provide constraints on the solar wind formation mechanisms.

Summary: In this study, double salt ionic liquids (DSILs) with triple ions were generated using parent ionic liquids. The conductivity of DSILs was measured and compared to that of the corresponding parent neat ionic liquids. The results showed that most DSILs had higher conductivity than the linear averages of the parent neat ionic liquids. The temperature dependence of DSILs was accurately described using the VTF equation and the relationships between parameters of the VTF equation and ion composition could be expressed by the first-order Fourier equation.

Summary: The study presents a convenient calibration method to evaluate factors affecting the conductivity of soils and substrates and establish necessary moisture-conductivity curves. The results show that in-phase conductivity increases with increasing VWC or dry density, with dry density having a relatively smaller effect on conductivity. Good power law relations can be established between in-phase conductivity and VWC at different frequencies.

Summary: This paper presents a novel sensor structure to improve the spatial resolution of electrical impedance tomography for mapping small-scale cylindrical plant root zones. Various simulations and experiments were conducted to assess the structure's ability in the electrode plane and the effects of measurement noise, conductivity contrast, radial position of internal electrodes, and measurement strategy on its performance. Results show that increased noise level or decreased conductivity contrast will decrease the resolution. Moreover, the internal-external electrodes exhibit benefits in improving and uniforming the resolution.

Summary: The RLCG parameters model and one-port measurement model of the closed-double ring electrodes have been established to obtain the dielectric properties of two-layer medium in radio frequency. The accuracy of these models was verified by electromagnetic simulation experiments and the permittivity measurement experiments under 160 MHz. Results showed that (1) When the medium dielectric constant εr is in the range of [6.03,78.8], the calculation values based on the models and the real values have a determination coefficient R-spc(2)=0.98 using the quadratic regression function fitting; (2) the effective sensing depth of the ring electrodes was about the structural wavelength of the ring electrodes; (3) the measuring permittivity of the intact mature corn ear were in good agreement with the results in the literature. This study demonstrates a practical technique to extract the permittivity of two-layer medium with the ring electrodes, and will provide a new way to in situ monitoring the physiological changes of two-layer medium and environmental parameters.

Summary: We propose a new scheme for magnetic state selection in optically detected compact cesium beam clocks. By pointing the atomic collimator to the convex pole of the magnet, we select atoms in the desired ground state and avoid the undesired states, reducing fluorescence background. The scheme improves the signal contrast and short-term frequency stability significantly.
