Ionic layer epitaxy (ILE) has recently been developed as an effective strategy to synthesize nanometer thick 2D materials with a nonlayered crystal structure, such as ZnO. The packing density of the amphiphilic monolayer is believed to be a key parameter that controls the nanosheet nucleation and growth. In this work, we systematically investigated the growth behavior of single-crystalline ZnO ...

Restacked niobate nanosheets were prepared by exfoliation of the corresponding Dion–Jacobson type layered perovskites (HCa2Nb3O10, HSr2Nb3O10 and HLaNb2O7) with tetra(n-butyl)ammonium hydroxide and subsequent treatment with hydrochloric acid. The nanosheets were characterized by means of X-ray diffraction, scanning electron microscopy, Raman spectroscopy, and diffuse reflectance spectroscopy. W...

Constructing nanostructures with desirable morphology and size is a critical issue for pursuing high performance electrode materials. Ultrathin Co3O4 nanosheet arrays, which are composed of well aligned uniform long-range (~5 μm in length) and thin (~10 nm in thickness) nanosheets, with reasonable mass loading on Ni foam are prepared by a two-step hydrothermal reaction. As a supercapacitor elec...

The lateral distribution and coverage of Ru-based dye molecules, which are used for dye-sensitized solar cells (DSCs), were directly examined on a titania surface using high-resolution scanning transmission electron microscopy (STEM). The clean surface of a free-standing titania nanosheet was first confirmed with atomic resolution, and then, the nanosheet was used as a substrate. A single dye m...

Titania nanosheets are two-dimensional single crystallites of titanium oxide with a thickness of one titanium or two oxygen atoms, and they show attractive material properties, such as photocatalytic reactions. Since a titania (Ti₀.₈₇O₂) nanosheet is synthesized by the delamination of a parent layered K₀.₈Ti₁.₇₃Li₀.₂₇O₄ crystal using a soft chemical procedure, substantial Ti vacancies are expec...

The present paper guides the reader through six decades of research on 2D materials, thereby putting special focus use these materials for electronic devices. It is shown that after a slow start and only little activity over many years, since 2004 exploration advanced at an enormous pace. While some high expectations raised in so-called golden era graphene did not fulfil, other applications ori...

Exploiting an advanced material simultaneously with effective thermal management (TM) and electromagnetic interference (EMI) shielding capacity is ungently demanded yet challenging for the miniaturized integrated electronics. Anisotropic networks can be impregnated phase change materials (PCMs) to fabricate multifunctional shape-stable PCMs (ss-CPCMs) excellent TM EMI shielding, which rarely re...

We report the successful growth of NiCo2S4 nanosheet films converted from NiCo2O4 nanosheet films on fluorine-doped tin oxide substrates by a low-temperature solution process. Low-cost NiCo2S4 and NiCo2O4 nanosheet films were directly used for replacing conventional Pt and NiO as counter electrodes and photocathodes, respectively, to construct all-nano p-type dye-sensitized solar cells (p-DSSCs...

Hybrid nanosuspensions were synthesised through ultrasonically dispersing ZrO2 or TiO2 nanoparticles into graphene oxide (GO) nanosheet solutions for water-based lubrication. The effect of contact pair roughness on the tribological behaviours ZrO2/GO and TiO2/GO hybrid investigated using a block-on-ring testing approach. With relatively smooth ring, use could reduce abrasive wear, hence improve...

In this work, we designed a sensitivity-enhanced surface plasmon resonance biosensor structure based on silicon nanosheet and two-dimensional transition metal dichalcogenides. This configuration contains six components: SF10 triangular prism, gold thin film, silicon nanosheet, two-dimensional MoS2/MoSe2/WS2/WSe2 (defined as MX2) layers, biomolecular analyte layer and sensing medium. The minimum...
