PLD and ALD amorphous alumina microcantilevers exhibit bending plasticity with >10% strain at room temperature while sputtered films fail brittly; all show fracture toughness of 3.1 MPa m^{0.5} with no crack-tip plasticity.
Physics-guided data augmentation combined with neural networks enables accurate indentation size effect correction in steels from small sets of shallow nanoindentation measurements, outperforming Nix-Gao in the shallow regime.
Tholins formed at 0.125 torr have threefold lower production rate but higher density and nanoindentation hardness than those at 1 torr, while particle size, morphology, surface energy, and Young's modulus remain similar.
