Summary: This study proposes an innovative theoretical model for purifying aqueous flowing solutions from ionic toxins. By applying an external electric field, the ionic toxins drift towards the walls of the duct, resulting in reduced toxin levels in the majority of the duct. The proposed model is suitable for small-scale water purification.

Summary: In this work, molecular dynamics simulations were conducted to investigate the drift mechanisms of ions and local structure evolution in biological dielectric liquids under external electric fields. The study revealed that the drift velocities of ions increased nonlinearly with the addition of static electric fields and the structural cages formed by biological dielectric molecules played a role in reducing ion transport.

Summary: Using the MAGE model, we simulated the penetrating electric field in the equatorial region under different IMF B-Z conditions. The simulation results showed that the dawn-dusk electric potential drop at the equator is about 12% of the cross polar cap potential difference in southward IMF cases. The simulation also revealed that the dawn-dusk potential drop at the equator varies nearly instantaneously with changes in the IMF B-Z or interplanetary electric field, which in turn affects the vertical ion drift. The ICON data, although inconclusive, were not able to verify the occurrence of the penetrating electric field due to its unfavorable location at the time. Further observations and modeling are needed to resolve this discrepancy.

Summary: This study aims to explain abnormal phenomena during coal and gas outbursts and understand the gas production effect of the micro-structure on outburst coal surface under the electric field. Experimental gas production systems were used to investigate the relationships between gas production and coal rank and excitation voltage. Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy were employed to analyze the changes in functional groups and chemical bonds on the coal sample surface after electric field excitation. The results revealed that CH4, CO, and CO2 were produced by medium-and low-rank coals under electric field excitation, and the gas production increased with higher excitation voltage. The analysis also showed changes in functional groups and chemical bonds on the coal surface after excitation. These findings provide theoretical support for understanding coal rock dynamic disasters and developing monitoring and pre-warning methods.

Summary: By using on-chip microdevices, the concentration of hydronium ions in electrochemical double layers can be fine-tuned for efficient hydrogen evolution. The electrical tests reveal that the back-gate voltage promotes charge transfer and polarization, attracting hydronium ions to accumulate near the reaction interface. The hydrogen evolution current is significantly increased with the back-gated hydronium enrichment.

Summary: The study investigates the desalination and water purification technology through the ion drift of saltwater flow in a duct using the Poison-Nernst-Plank equations. The research suggests that the linear approximation provides accurate results only in the bulk of the fluid but not within the double layer. Additionally, the study proposes a potential method to overcome the issue of electric field diminishing in the fluid's bulk.

Summary: In this paper, we studied a square lattice with correlated random hopping terms under an external electric field. By using a Taylor formalism to solve the Schrodinger dynamic equation, we analyzed the dynamics of an initially localized electronic wave packet. Our calculations showed that the correlated disorder promotes fast electronic propagation for intermediate times. When a static electric field is applied, we observed oscillatory behavior similar to the well-known Bloch oscillations. The frequency of these oscillations was calculated and found to be in good agreement with predictions from the semi-classical approach used in crystalline lattices. We discussed the stability of these apparent Bloch oscillations based on the local disorder and the absence of extended states in our model.

Summary: The adsorption performance of ten gas molecules on graphene/WSe2 heterostructure is studied, and it is found that gas molecules are physisorbed on the heterostructure surface due to weak interface interactions. Among these gas molecules, NO2 shows the strongest interaction with the heterostructure, indicating high selectivity. Additionally, NO2 acts as an electron acceptor and reduces the Schottky barrier height of the heterostructure. The adsorption properties can be regulated by an external electric field, and the sensitivity of NO2 on the heterostructure can be enhanced under a large positive electric field. This work provides insights for designing high sensitivity and selectivity WSe2-based sensors.

Summary: An electron electric dipole moment (eEDM) search using laser-coolable triatomics such as YbOH is a sensitive probe for physics beyond the standard model. The study found that the polarization efficiency of triatomic molecules is usually less than 50%, which is related to the Hund's b coupling scheme.

Summary: In this study, the electric field level of discharge in the dielectric and the direction of the molecular intrinsic dipole moment were analyzed using density functional theory and time-dependent density functional theory. It was found that the electric field significantly affected the molecular structure and bond length. The ionization potential of C3F7SO2F molecule decreased under an electric field in the -z-axis direction, facilitating the liberation of electrons and the propagation of streamer. Therefore, it is important to reduce or remove C3F7SO2F molecule during the preparation process of CF3SO2F to prevent a reduction in dielectric insulation strength.

Summary: In this study, the kinetic characteristics of electron drift in two inert gases, helium and xenon, were calculated using the Monte Carlo method. The main characteristics of electron drift and diffusion coefficients were obtained through numerical simulation. The results showed that the magnetic field led to a decrease in the drift velocity and mean energy of electrons. These calculations can be used to analyze experimental data on electron drift and diffusion in crossed electric and magnetic fields.
