A Step-by-Step Strategy for Controlled Preparations of Complex Heterostructured Colloids
Bibliographic record
Abstract
Interest in the preparation of colloidal heterostructures with complex shapes, structures, and spatial compositions is driven by their unique optical, electrical, magnetic, or rheological properties. Despite recent advances, it is highly desired but challenging to further extend the library of heterostructured particles with increased degrees of complexity. Here we report a general step-by-step strategy for controlled preparations of complex heterostructured colloids with various structures and compositions. A local-curvature-controlled emulsion polymerization method is first employed for site-selective growth of secondary polystyrene nanostructures on different nonspherical colloidal seeds. The following functionalization and selective removal steps further increase the degree of particle complexity. We also demonstrate a new type of chemically powered nanomotors based on heterostructured α-Fe2O3@SiO2/Pt particles. This growth strategy is a versatile, general method suitable for the preparation of complex heterostructured particles with tailored structures, compositions, and functionalities, paving the way for their applications for various purposes.

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.
