Microwave-assisted green synthesis of monodispersed carbon micro-spheres and their antibacterial activity
Bibliographic record
Abstract
Well-dispersed mono-carbon microspheres were synthesized via the hydrothermal carbonization of ascorbic acid (AA) using a microwave reactor without adding any catalyst. The synthesized materials were characterized by various microscopic and spectroscopic techniques (e.g., SEM, TEM, XRD, Raman, XPS, EDX, and FTIR spectroscopy), showing that the formed carbon spheres (CSs) exhibited uniform morphology and surface structure with abundant oxygen functional groups. The dimension of the formed CSs could be easily tuned by altering the AA concentration, reaction time, and temperature. A mechanism for the formation of the CSs was proposed, and their antibacterial activities were also investigated against two bacterial strains, showing the inhibition rate of 94% for E. coli and 100% for S. aureus . This biocidal activity was achieved with the pure CSs produced from the inexpensive AA (Vitamin C) via a rapid green process without any further surface modification or doping, thus promising for myriad surface coating, medical and environmental applications.

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.
