Experimental evidence for ferromagnetic ordering in isotropic atomically thin two-dimensional crystals has been missing until a bilayer Cr2Ge2Te6, and three-atom thick monolayer CrI3 are shown to retain at finite temperatures. Here, we demonstrate successful isolation of non-van der Waals type ultra-thin nanosheet FeS2 derived from naturally occurring pyrite mineral (FeS2) by means liquid-phase...

Two-dimensional (2D) nanomaterials have been considered as a promising materials platform for next-generation electronics due to their unique electronic, optical, and mechanical properties. Since the first graphene exfoliation method has reported, other layered having structural analogues with different electrical properties further explored discover semiconducting candidates. For example, MoS2...

A direct and metal layer-free growth of flat graphene pads on exfoliated hexagonal boron nitride substrate (h-BN) are demonstrated by atmospheric chemical vapour deposition (CVD) process. Round shape with high flatness graphene pads are grown in high yield (∼95%) with a pad thickness of ∼0.5 nm and homogenous diameter.

We report microporous carbon nanosheets containing numerous redox active heteroatoms fabricated from exfoliated waste coffee grounds by simple heating with KOH for pseudocapacitive charge storage. We found that various heteroatom combinations in carbonaceous materials can be a redox host for lithium ion storage. The bio-inspired nanomaterials had unique characteristics, showing superior electro...

Graphite with a large inter-planar distance (0.357 nm) was obtained from pig bone. It delivered an improving specific capacity which increased continuously to 538 mA h g(-1) at 1 A g(-1) after 1000 cycles. With microscopic characterization, it has been found that the pig-bone-based graphite was exfoliated to graphene during the charge-discharge process.

Graphitic carbon nitride (g-C3N4) was synthesized from melamine and exfoliated by thermal treatment. Exfoliated g-C3N4 particles were immobilized electrophoretic deposition an ultrasonically treated ethanolic suspension aged up to 12 weeks. During the aging of suspension, separation bigger than 10 ?m observed. The separated stable part contained with a relatively uniform size distribution, enab...

Children may be more susceptible to the effects of the environmental exposure and medical treatments than adults; however, limited information is available about the differences in genotoxic effects in children by age, sex and health status. Micronucleus (MN) assay is a well established method of monitoring genotoxicity, and this approach is thoroughly validated for adult lymphocytes by the Hum...

Graphite was electrochemically exfoliated in mixtures of room temperature ionic liquids and deionized water containing lithium salts to produce functionalized graphenes and such an electrochemical exfoliation technique can be directly used in making primary battery electrodes with significantly enhanced specific energy capacity.

The melting transition of Xe monolayers adsorbed on a single-crystal exfoliated graphite substrate has been studied by high-resolution synchrotron x-ray scattering. At temperatures slightly above the melting transition the fluid phase has a high degree of orientational order. The results are discussed in the context of current theories of two-dimensional melting including the effects of the sub...

High-quality large-sized hexagoal WSe2 crystals can be grown on dielectric substrates using atmospheric chemical vapor deposition in the presence of hydrogen gas. These hexagonal crystals (lateral width >160 um) have a carrier mobility of 100 cm(2) V(-1) s(-1) and a photoresponsivity of ≈1100 mA W(-1), which is comparable to that of exfoliated flakes.
