Abstract
Since the use cellulose whiskers, cellulose microfibrils, and cellulose fibres of micro- and nano-scale diameters as reinforcing agents in composites is increasing rapidly, there is a need to review the microstructure of cellulose in great detail. In this paper, the concept of "microfibres" of cellulose has been developed based on a consideration of bleached kraft pulp cell wall morphology. First, the structure of a cellulose microfibril in wood cell wall has been elucidated through a structural analysis of wood cell wall. Subsequently, the need to define microfibres as "fibres" for structural applications has been demonstrated, and contrasted with the convential definition of microfibrils, which are attached to the cell wall at one end. It is proposed that microfibres should have a minimum aspect ratio of 50 for adequate stress transfer from the matrix to the fibre. Consequently, microfibres were defined as cellulose strands 0.1-1 μm in diameter, with a corresponding minimum length of 5-50 μm. The reinforcing potential of cellulose microfibres was demonstrated by using them in composites with a polyvinyl alcohol (PVA) matrix.

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 it
