Urchin-Shaped Bi<sub>2</sub>S<sub>3</sub>/Cu<sub>2</sub>S/Cu<sub>3</sub>BiS<sub>3</sub> Composites with Enhanced Photothermal and CT Imaging Performance
Bibliographic record
Abstract
Urchin-shaped Bi 2 S 3 /Cu 2 S/Cu 3 BiS 3 nanocomposites were successfully prepared in this study through one-pot synthesis, which involved microwave-assisted simultaneous pyrolysis of two precursors. The as-prepared Bi 2 S 3 /Cu 2 S/Cu 3 BiS 3 hybrids exhibit stronger absorption in the near-infrared regime than the individual components, i.e., Bi 2 S 3, Cu 2 S, and Cu 3 BiS 3 . The photothermal conversion efficiency (η) of Bi 2 S 3 /Cu 2 S/Cu 3 BiS 3 composites can even reach 43.8%, which is significantly higher than that seen with most of the transition metal chalcogenide materials. The excellent photothermal performance of Bi 2 S 3 /Cu 2 S/Cu 3 BiS 3 hybrids is likely arising from its unique urchin-like structure, in which needle-like Bi 2 S 3 /Cu 2 S nanocomposites grow from the core of Cu 3 BiS 3 . The copresence of Bi 2 S 3 and Cu 2 S also leads this newly synthesized composite to produce high contrast for X-ray computer tomography imaging, an important property required for a great potential application in theranostic cancer treatment.

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.
