Abstract

The core-shell structured SiO 2 @Ni-Al layered double hydroxide (LDH) composites were prepared via self-assembly of Ni-Al LDH on the surface of SiO 2 spheres. Only coating a layer of ultrathin Ni-Al LDH sheet, the resulting SiO 2 @Ni-Al LDH composites exhibit significantly enhanced electrorheological (ER) characteristics compared to conventional bare SiO 2 spheres. The monodispersed SiO 2 spheres with average diameters of 260 nm were synthesized by the hydrolysis of tetraethyl orthosilicate (TEOS), while the shell part, Ni-Al LDH sheet was prepared by the hydrothermal procedure. The morphology of the samples was investigated via scanning transmission electron microscopy (STEM), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The structure of the samples was characterized by X-ray diffraction (XRD). The species and distribution of elements in samples were confirmed by X-ray photoelectron spectroscopy (XPS), Energy dispersive analysis of X-ray (EDX) and elemental mapping in STEM. Subsequently, the ER characteristics of the composites dispersed in insulating oil were characterized by a rotational rheometer. The electric field-stimulated rheological performances (yield stress, viscosity, modulus, etc.) were observed under an external electric field, which is different from the Newtonian state in the free electric field.

  • Graphene-based nanocomposites have the potential to ameliorate energy storage devices by leveraging the ample specific surface area of graphene and Faradaic redox reactions of TMDs or LDHs.

    “Such graphene-based nanocomposites have the potential to ameliorate energy storage devices by leveraging the ample specific surface area of graphene and Faradaic redox reactions of TMDs or LDHs.27−32”

    From Integrated Energy Aerogel of N,S-rGO/WSe <sub>2</sub> /NiFe-LDH for Both Energy Conversion and Storage (2017) · cites this paper as [31]

    The paper’s introductory passage (indexed under Abstract; no page given) says LDHs have been used as electrodes for batteries and supercapacitors, and its References list a graphene–LDH supercapacitor electrode. It does not explain improved energy storage through graphene’s specific surface area or Faradaic redox reactions of LDHs or TMDs; its focus is electrorheological performance. (LLM, conf=0.78)

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.
