Abstract

fetched live from OpenAlex

The dominant form of mercury in the atmosphere is Hg 0 .The oxidation processes are of great importance since oxidized mercury undergoes deposition and can become subject to bio-accumulation.Experimental data on the gaseous reactions of elemental mercury are very limited with compare to the reactions of Hg 0 in solutions.We herein carried out kinetic and product studies on the reactions of gaseous Hg 0 with O3 and hydroxyl radical (HO) under near atmospheric pressure (750  1 Torr) and room temperature (298  1 K) in air and N2.O3 was produced in a silent discharge generator (OL 100/SB).Hydroxyl radicals were produced from the photolysis of isopropyl nitrite in the presence of NO.Kinetics of the reactions with O3/HO was studied using absolute and relative techniques by gas chromatography with mass spectroscopic detection (GC-MS).The gas phase reaction between elemental Hg 0 with O3, has been studied in different surface-to-volume (sly) ratios, and evidence for heterogeneous reactions was observed.Existence of mercuric oxide, HgO by the reaction of atomic Hg 0 with O3 has been determined in the gas phase from the suspended aerosols using high temperature mass spectrometry.

Teacher imitation

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.
