Abstract
Two major effects of pressure in nanomaterials are discussed in this chapter. First, the pressure-induced phase transitions in nanomaterials often differ significantly from those of their bulk counterparts. This opens the opportunity of including surface energy contributions in thermodynamic models. The importance or even the dominance of surface atoms and the underlying surface state (point defects, ligands, etc.) greatly influence the thermodynamics and kinetics of phase transformations. This can lead to a competition between pressure-induced polymorphic transitions and amorphization depending on the defect density in the nanomaterials. Second, the mechanical properties of 2D materials such as graphene are difficult to apprehend because of their dimensionality. The variation over a wide range of pressure allows a better understanding of the stress transfer through the substrate and its role in the production of biaxial strain conditions. The mechanism of stress transmission to an atomically-thin material will be discussed, and a practical example that aims to determine the coupling between components in graphene-based nanocomposites will be presented.

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.
