Large-area microfabrication of three-dimensional, helical polymer structures
Bibliographic record
Abstract
A technique has been developed to fabricate polymeric helixes with sub-micron dimensions. These helixes are made using a double-templating process, in which an inorg. thin film deposited using glancing angle deposition acts as the master. The shape, pitch, handedness and no. of turns of the polymer helixes can be tuned by altering the deposition parameters of the master film. The structure of this pos. master is copied into a neg. intermediate template of photoresist, which itself acts as a master for the templating of polymer helixes. This process is demonstrated with four multifunctional acrylates. The master, intermediate template and polymer helixes are characterized using SEM, and the polymer helixes are characterized using energy dispersive x-ray spectroscopy. It is shown that a large no. of polymer helical microstructures, which are anchored to both a thick substrate and a thin capping layer, can be made in parallel over areas of mm2 to cm2.

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.
