Substituent Effects on the Adsorption of Dialkyl Sulfides on Gold Nanoparticles
Bibliographic record
Abstract
The adsorption of chloroethyl ethyl sulfide and 2,2'-dichloro ethyl sulfide to gold nanoparticles has been examined in the gas phase using surface-plasmon resonance spectroscopy. The equilibrium constants for the gas-phase adsorption reactions are 14 +/- 4 and 25 +/- 5 atm(-1), respectively. The bond energy of the Au-chloroethyl ethyl sulfide complex is 44 +/- 9 kJ mol(-1). The bond energy of Au-2,2'-dichloro ethyl sulfide is estimated to be 47 kJ mol(-1). Halogenation of the dialkyl side chains is found to have little impact on the chemistry, and only physisorption processes occur, analogous to dialkyl sulfide adsorption on Au surfaces.

How this classification was reachedexpand
Full frame distilled prediction
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
