Colloidal Behavior of Cellulose Nanocrystals in Presence of Sodium Chloride
Bibliographic record
Abstract
Abstract Aggregation and gelation of cellulose nanocrystals (CNCs) induced by sodium chloride (NaCl) were investigated as a function of NaCl and CNC concentrations. Incorporation of NaCl improved CNCs ability to form clusters via screening surface charges of CNCs. Transmission electron microscopy (TEM) images revealed the formation of porous CNC clusters following NaCl addition. The confocal laser scanning microscopy (CLSM) micrographs indicated the presence of regions with colloid‐rich and colloid‐poor patterns in CNC clusters. Fluorescent brightener 28 was found to have a strong hydrogen bonding to the cellulose surface and used as the staining agent in CLSM. The CLSM images also indicated a dynamic structure for gels, continually rearranging over the course of time. Zeta potential data coupled with CLSM images confirmed the impact of NaCl on the gel formation of CNCs.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
