Microsprings and microcantilevers: studies of mechanical response
Bibliographic record
Abstract
Porous thin films with unique microstructures have been fabricated with the glancing angle deposition technique. This technique utilizes highly oblique deposition angles to make use of initial growth and shadowing conditions, which allow thin films consisting of microsprings and arrays of microcantilevers to be engineered with nanometre scale control. The mechanical properties of these microstructured films were studied with a nanoindentation technique. Several microscopic `springbed' films were tested over a range of forces using a spherical indenter tip. The geometries of the microsprings were varied, and a number of different materials were used to fabricate these films, which were typically a few micrometres thick. Slanted post arrays, resembling microscopic cantilevers, were also subjected to nanoindentation tests. The results of initial experiments and theory show that these microstructures behave in a manner analogous to macroscopic springs and cantilevers, and may offer opportunities for application as resonator devices.

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.
