Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In tandem catalytic pyrolysis-CVD over Ni foam, polyolefin plastics (HDPE/LDPE/PP) yield highly crystalline carbon nanomaterials, high hydrogen selectivity, and low-impurity liquid oil due to their single-stage decomposition behavior and high alkane content.

    “Results showed that polyolefin plastics (HDPE/LDPE/PP), due to their single-stage decomposition behavior and high alkane content, yielded highly crystalline carbon nanomaterials on the Ni foam, simultaneously achieving high hydrogen selectivity and low-impurity liquid oil production.”
  • PET led to 42% amorphous carbon deposition and suppressed hydrogen yield due to oxygen-containing COx byproducts.

    “PET, however, led to 42% amorphous carbon deposition and suppressed hydrogen yield due to oxygen-containing CO x byproducts.”
  • In the same process, PS generated 84 wt% high-value aromatic oil.

    “In contrast, PS, dominated by aromatic hydrocarbons in its pyrolysis products, generated 84 wt% high-value aromatic oil.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
