Effects of Confinement on Arborescent Graft Polystyrene Particle Shape
Bibliographic record
Abstract
Abstract Arborescent graft polymers are highly branched materials synthesized by grafting multiple generations of macromolecular precursors on a central core [1,2]. They can be synthesized with controllable size and molecular weight depending on the number of generations and the precursor molecular weight. They possess many of the unique structural [3], thermodynamic, and rheological [4] properties of dendrimers but do so on a length scale roughly one order of magnitude higher. This research describes the effect of confinement on the shape of arborescent graft polystyrene (PS). This work used 3rd generation arborescent graft PS synthesized with 5kg/mole linear polystyrene precursor (G3- 5K). The G3-5K PS sample was mixed to a dilution of approximately 0.005 wt% in toluene. A single drop of solution was placed on either a holey-carbon film or an ultrathin continuous carbon film. The solvent was evaporated under ambient conditions. A Philips CM20 FEG TEM/STEM equipped with a Gatan 666 PEELS and a 679 multiscan CCD camera was used to study the structure of these specimens.

How this classification was reachedexpand
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.
