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?

  • Nano Si-based inorganic particles deteriorated the shape memory effect of shape memory polymers even at very low loading.

    “Research at the early 90s showed that nano Si-based inorganic particles deteriorated the SME of SMPs even at very low loading.”
  • Gunes et al. observed negative effect of SiC on the SME of SMPUs, which they ascribed as due to the dramatically decreased soft segment crystallinity of the SMPU.

    “Gunes et al. [52,324] also observed negative effect of SiC on the SME of SMPUs, which they ascribed as due to the dramatically decreased soft segment crystallinity of the SMPU.”
  • SMPNCs showed greater stiffness and tensile strength than pure SMPs, which help overcome problems associated with shape-memory materials.

    “Interestingly, such SMPNCs showed greater stiffness and tensile strength than pure SMPs, which help to overcome the problems associated with such shape-memory materials.40,41”
  • Fillers can negatively affect shape recoverability of an SMP due to their size and higher stiffness compared to matrix polymer, and at high loading levels may disturb polymer networks responsible for SM functionality.

    “However, in some cases fillers are prone to have negative effects on the shape recoverability of an SMP due to their size and substantially higher stiffness compared to the matrix polymer.At high loading levels, they may even disturb the polymer networks responsible for SM functionality [198].”

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.
