Abstract

fetched live from OpenAlex

Abstract We investigate how a dielectric barrier discharge is affected by a layer of iron nanoparticles deposited on top of one of the dielectrics. Specifically, an atmospheric pressure Townsend discharge is generated in pure nitrogen, and we find that when the Fe nanoparticle coating on the dielectric is conductive, it notably influences the dielectric capacitance. Due to the altered capacitance, an update to the equivalent circuit that is used to analyze the discharge is required. Employing the updated equivalent circuit, where the dielectric capacitance of the discharging fraction is replaced by the highest available dielectric capacitance, we show that the increased capacitance due to the conductive layer clearly affects the discharge characteristics, such as the current and deposited power. In addition, we observe a decrease in the discharge voltage caused by the iron nanoparticles, indicating that there may be surface effects enhancing the release of charges, enabling a discharge at lower voltages. This work offers additional insights into the mechanisms influencing dielectric barrier discharges, especially the effects of materials exposed to the plasma. Moreover, it enables a broader application and interpretation of the electrical characterization of DBDs, for example for an expanded discharge, which is crucial to understand the plasma properties.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
