Preparation and characterization of cysteine‐formaldehyde cross‐linked complex for CO<sub>2</sub> capture
Bibliographic record
Abstract
This work focused on the preparation and characterization of cysteine‐formaldehyde cross‐linked complex derived from cysteine hydrochloride and formaldehyde. The cross‐linked complex was prepared based on the nucleophilic substitution reaction of cysteine with formaldehyde accompanied by π bond breakage of carbonyl from formaldehyde. Meanwhile, its surface morphology, element composition, group distribution, and thermodynamics were experimentally investigated by means of SEM, XRD, EA, EDS, 1 H‐NMR, FTIR, BET, and TGA as well as an analysis of the characteristics of CO 2 adsorption. The results indicated that the as‐prepared cross‐linked complex exhibited a rod‐shaped hollow crystal structure with a lateral distribution of sulphur and nitrogen atoms toward the crystal surface. As a mesoporous crystal material, the cross‐linked complex presented a four‐step (amide forming, fast pyrolysis, slow pyrolysis, and dehydrogenation) pyrolysis above 430 K, yet possessed a relatively acceptable thermodynamic stability below 430 K. In addition, the interaction mechanism between the cysteine hydrochloride and formaldehyde was revealed by characteristics and simulation.

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.
