A novel electroactive hybrid film electrode with proton buffer effect for detecting hydrogen peroxide and uric acid
Bibliographic record
Abstract
In this study, a novel hybrid film electrode with proton buffer effect for the detection of hydrogen peroxide (H2O2) and uric acid (UA) was fabricated by a facile one-step electrosynthesis method using cyclic voltammetry (CV). The electrode was composed of a nickel hexacyanoferrate cubic nanoparticle (NiHCNP) inlaid poly(neutral-red) (PN) film formed on carbon nanotube-(CNTs) modified glassy carbon (GC) plate. PN in the hybrid film was found to not only act as a proton buffer, which can receive and release protons to meet the demands of electrocatalytic reaction, but also to anchor NiHCNP on the surface of CNTs and stabilize NiHCNP. The morphology and structure of the as-prepared NiHCNP/PN/CNTs hybrid film was characterized using scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray spectrum (EDS), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). The prepared hybrid film electrodes showed excellent electrocatalytic activity with high sensitivity, fast response time and low detection limit for the detection of H2O2 as well as UA.

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.
