Abstract

fetched live from OpenAlex

A one‐step in‐situ route to free standing core–shell silicon carbide in graphene nanoparticles on monolayer graphene is presented. The core–shell SiC@Graphene nanoparticle growth is realized by a simple chemical vapor deposition (CVD) process where carbon and silica precursors are simultaneously introduced into the growth chamber. This process permits the synthesis of a monolayer graphene sheet dressed with silicon carbide nanoparticles in a single CVD step, with the product controlled by growth temperature and the carbon/SiO2 exposure time. Growth of a high density SiC@Graphene distribution on a continuous graphene layer requires long exposure times (>1 h) and high temperature (1000 °C). The growth process proceeds by a carbothermal mechanism. The simultaneous growth of graphene and SiC nanoparticles enables uniform core–shell SiC@Graphene nanoparticle formation rather than SiC/carbon nanofiber growth. As a proof of concept, the functionalization of preformed nanoparticle graphene surface with a diazonium salt is studied, demonstrating an increase in grafting rate with increasing nanoparticle population. This work provides a general procedure for one‐step synthesis, with further investigation required to develop precursors for hybrid core–shell CVD material growth.

Not 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.
