A solvothermal single‐step route towards shape‐controlled titanium dioxide nanocrystals
Bibliographic record
Abstract
Abstract A versatile synthetic method which is based on a solvothermal technique for the fabrication of highly crystalline TiO 2 nanocrystals (NC) exhibiting different shapes such as rhombic, truncated rhombic, spherical, dog‐bone, truncated, and elongated rhombic is reported. The dominant features of the present approach are first the use of water vapor as hydrolysis agent to accelerate the reaction, and second, the use of both oleic acid (OA) and oleylamine (OM) as two distinct capping surfactants having different binding strengths for the control of the growth of the TiO 2 nanoparticles. It is shown that the presence of an appropriate amount of water vapor along with the desired OA/OM molar ratio plays a crucial role in controlling size and shape of TiO 2 NCs. Moreover, it is also established that the thus‐obtained TiO 2 NCs are excellent support for the synthesis of composite metal/TiO 2 photocatalysts in which metal clusters are uniformly deposited on the surface of each individual TiO 2 NC. © 2011 Canadian Society for Chemical Engineering

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
