Summary: This study investigates the impact of direct and alternating current electric field on quality variety tomatoes and explores the mechanism behind it. Results show that alternating current electric field with specific treatment times have a more significant efficiency in prolonging the shelflife of tomatoes. They reduce weight loss, browning, ascorbic acid loss, and quality deterioration during storage, while other treatments have limited efficiency in this regard.

Summary: In this study, a polycation additive, polydiallyl dimethylammonium chloride (PDD), is introduced to achieve long-term and highly reversible Zn plating/stripping. The PDD can regulate the electric fields of electrolyte and Zn/electrolyte interface to improve Zn2+ migration behaviors and guide dominant Zn (002) deposition. Moreover, PDD creates a positive charge-rich protective outer layer and a N-rich hybrid inner layer to enhance the Zn2+ desolvation and prevent direct water contact with the Zn anode, resulting in improved reversibility and long-term stability of Zn anodes.

Summary: This paper proposes a unique method called insulator-decorated bipolar electrochemistry(IDBE) for large-scale separation of bioparticles in microchannels using AC dielectrophoresis (DEP). By extending the range of DEP force field, the IDBE method enables highly efficient separation of live and dead yeast cells in a microchip.

Summary: In this study, the effects of AC EFs on corneal epithelial cell gene and protein expression profiles were investigated. The results show that AC EFs have no harmful effects on epithelial cell function, and influence biological processes related to organic substances, chemicals, or external stimuli. Both gene and protein arrays activate pathways such as cytokine-cytokine receptor interaction, MAPK, and IL-17 signaling pathways. The protein array data demonstrate enrichment of various signaling pathways through interconnected networks.

Summary: Therapeutic alternating electric fields (TTFields) is a new form of anti-cancer therapy that has shown improved survival outcomes in patients, either alone or in combination with chemotherapy. However, the mechanisms of TTFields are not fully understood, and ongoing investigations are aimed at better understanding how it selectively kills cancer cells and impedes their proliferation.

Summary: This study comprehensively investigates the salt rejection and fouling on non-conductive membranes in the electric fields of direct current (DC) and alternating current (AC). A membrane cell design is used to apply electric fields on traditional non-conductive membranes. The results show that AC and DC within 1V have a minimal impact on ion rejection and organic fouling, but can effectively mitigate scaling at certain conditions. The scaling tendency is significantly influenced by current direction, frequency, waveform, and bias. AC field exhibits better anti-scaling performance due to continuous ion motion, offering a more energy-effective strategy for scaling reduction compared to DC.

Summary: This article examines the effect of alternating electrical fields on cancer cell proliferation and proposes the combination of Daunorubicin with electric field exposure as a potential anti-cancer therapy. The results demonstrate that electric fields can selectively damage cancer cells while sparing normal cells, and also enhance the uptake of chemotherapy agents by cancer cells.

Summary: As transcranial electrical stimulation (tES) protocols advance, the assumptions underlying the technique need to be retested. This study reports adverse events (AEs) and blinding data from 1,019 participants who received multiple sessions of active or sham tACS, tDCS, and tRNS. The results suggest that factors other than tES may predict AEs, and the efficacy of blinding may vary depending on the type of stimulation.

Summary: This study investigates systems containing oppositely charged colloidal particles under applied alternating current electric fields using overdamped Langevin dynamics simulations. The results show the formation of jammed bands perpendicular to the field direction under intermediate frequencies and lanes parallel with the field under low frequencies, depending on particle charges. The pathway for generating these bands follows a stepwise mechanism, with observations of intermediate bands in some systems. Additionally, the transition from jammed bands to lanes is found to occur at a critical value of pressure tensors parallel to the field direction, with stable steady states conforming to the principle of maximum entropy production.

Summary: This study investigates the effects of electric fields on the mechanical properties and microstructure of brain tissue. The results show that a directional electric field reduces the elastic properties of brain tissue, increases cell spacing, and reduces proteoglycan content. On the other hand, an alternating electric field accelerates stress relaxation in brain tissue and changes its time-dependent mechanical properties. Understanding these changes in brain tissue under different electric fields provides insight into the therapeutic mechanisms of electrotherapy and supports the development of embedded electrodes.

Summary: Porous materials with nanometer-scale pores have important applications as nanoporous membranes. In this study, ABA triblock copolymers were used as precursors to produce nanoporous polymeric membranes (NPMs) in thin film form by degrading the end blocks. Polycyclooctene (PCOE) NPMs with tunable pore sizes were successfully prepared using solvent casting technique. Oxygen plasma etching was employed to improve the surface porosity and hydrophilicity of the membranes. This study provides a straightforward method to produce tough NPMs with high porosity and hydrophilic surface properties.

Summary: The optical properties of liquid crystals are typically controlled by electric fields. In this study, we investigate the effects of microfluidic flows and acoustic fields on the molecular orientation and optical response of nematic liquid crystals. We identify several previously unknown structures and explain them through calculations and simulations. These findings hold promise for the development of new systems combining sound, flow, and confinement.
