Abstract
The influence of ceramic specific capacitance (i.e. area, thickness and dielectric permittivity) on plasma intensity, which ultimately is correlated with the charge transferred in microdischarges, was studied in a dielectric barrier discharge reactor (DBD) at ambient conditions. The reactor operates at applied voltages ranging from 1–10kV and applied frequencies of l-8kHz. The natural gas is injected in the plasma zone yielding hydrogen and solid carbon, with no CO or CO2 release. This study showed that the increase in ceramic specific capacitance results in the increase in hydrogen yield and methane conversion rates due to the increase in the number of micro-discharges for higher dielectric constants. For dielectric constants ranging from 9 to 166 the hydrogen yield increased from 0.3% to 1.35%. In addition, the results suggest that CH4 conversion rates of 2 and 6% were obtained for ceramics with dielectric constants of 9 and 166, respectively.

Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
