Abstract

fetched live from OpenAlex

Abstract Polyacrylamide (PAM) is grafted from the surface of activated carbon (AC) by surface‐initiated activators generated by electron transfer atom transfer radical polymerization (SI‐AGET ATRP). This is accomplished by pre‐functionalizing the surface of activated carbon by oxidation, followed by the attachment of an ATRP initiator. From this surface, SI‐AGET ATRP of acrylamide monomers is performed. The resulting AC‐PAM is characterized by FTIR, XPS, TGA, and BET analysis. Additionally, the grafted polymer is cleaved from the surface of AC and its molecular weight distribution is measured by SEC. This material is designed to explore the effect that grafting a polymer flocculant onto AC will have on the polymer's flocculating abilities. This is evaluated by measuring the flocculation and dewatering of mature fine tailings (MFT) when dosed with the AC‐PAM compared to PAM. In all, this work demonstrates the successful grafting of PAM onto AC, as well as potential wastewater applications for this composite material.

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.
