The unique nano–bio interfacial phenomena play a crucial role in the biosafety and bioapplications of nanomaterials. As representative two-dimensional (2D) nanomaterial, molybdenum disulfide (MoS2) has shown great potential biological applications due to its low toxicity fascinating physicochemical properties. This review aims highlight interface MoS2 nanomaterials with major biomolecules impli...

Abstract The friction between a molybdenum disulphide (MoS 2 ) nanoflake and MoS substrate was analyzed using modified Tomlinson model based on atomistic force fields. calculations performed in the study suggest that large deformations can induce dramatic decrease to produce so-called superlubricity. coefficient of decreases by 1–4 orders magnitude when high strain exceeding 0.1 is applied. Thi...

Abstract This paper reports the fabrication of an artificial synapse (AS) based on two-dimensional molybdenum disulfide (MoS 2 ) film. The AS emulates important synaptic functions such as paired-pulse facilitation, spike-rate dependent plasticity, spike-duration plasticity and spike-number plasticity. spike voltage can mediate ion migration in gel to regulate conductance MoS channel, thereby re...

We have investigated the effects of metal decoration on the gas-sensing properties of a device with two-dimensional (2D) molybdenum disulfide (MoS₂) flake channels and graphene electrodes. The 2D hybrid-structure device sensitively detected NO₂ gas molecules (>1.2 ppm) as well as NH₃ (>10 ppm). Metal nanoparticles (NPs) could tune the electronic properties of the 2D graphene/MoS₂ device, increa...

Recent investigations of semiconducting two-dimensional (2D) transition metal dichalcogenides have provided evidence for strong light absorption relative to its thickness attributed to high density of states. Stacking a combination of metallic, insulating, and semiconducting 2D materials enables functional devices with atomic thicknesses. While photovoltaic cells based on 2D materials have been...

We have performed ab initio quantum mechanical calculations to describe scanning tunneling microscopy (STM) images of MoS 2 and MoTe2 . These results indicate that the interpretation of the STM images of these and related materials depends sensitively on experimental conditions. For example, determining whether the maximum tunneling current correlates to the top atom ( S or Te) or to the second...
