Large-Scale Aqueous Synthesis and Growth Mechanism of Single-Crystalline Metal Nanoscrolls at Room Temperature: The Case of Nickel
Bibliographic record
Abstract
Here we report a simple and versatile one-pot route for the large-scale synthesis of single-crystalline Ni nanoscrolls at room temperature. The procedure is very simple, and only two chemicals (NiCl 2 and commercial Mn powder) were used throughout the entire synthetic process. Through a systematic investigation on the morphologies of the products collected from different growth stages, direct evidence of the evolution process, from a flat sheet to the formation of one-sided and two-sided nanoscrolls, is presented. Further, the disassociation of the as-synthesized nanoscrolls induced by the converged transmission electron microscope (TEM) electron-beam irradiation confirms the scroll-type structures. A corresponding growth mechanism of Ni nanoscrolls is proposed. In addition, we have successfully extended this simple method to synthesize La metal nanoscrolls. We believe that this method offers an attractive and simple way for the large-scale synthesis of other metal nanoscrolls.

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.
