Universal Method for the Fabrication of Detachable Ultrathin Films of Several Transition Metal Oxides
Bibliographic record
Abstract
Ultrathin films are important nanoscale structures that are used extensively in a variety of technological contexts. However, it has traditionally been difficult and costly to fabricate detachable and purely inorganic high aspect ratio films with controlled thickness and good uniformity. Here we report a versatile method to make separable purely inorganic membranes of various metal oxides such as Nb(2)O(5), TiO(2), WO(3), and Ta(2)O(5) with thicknesses ranging from 30 to 150 nm. Fluoride ions are migrated through the oxide film and upon arrival at the oxide-metal interface form a sacrificial soluble oxyfluoride layer. Fluorine also plays a role in controlling the porosity of the films. The study exposes the mechanism behind the detachment process that is largely due to the fast migration of fluoride anions relative to oxygen anions. The resulting films have a wide range of potential applications as catalysts or catalyst supports, filtration membranes, sensors, and more.

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.
