Evaluating the Exfoliation Efficiency of Quasi-2D Metal Diboride Nanosheets Using Hansen Solubility Parameters.
Hansen solubility parameters are applied to identify cosolvent blends suitable for CrB2 and MgB2 that produce dispersions with concentrations that match or exceed those of the top-performing individual solvents for each material and that have markedly higher stability compared to the constituentsolvents of the blends alone.
Exfoliation of boron carbide into ultrathin nanosheets.
This work elucidates the exfoliation mechanism of 2D B4C and suggests that LPE can be applied to generate nanosheets from a variety of non-layered and non-vdW materials.
Directly Exfoliated Ultrathin Silicon Nanosheets for Enhanced Photocatalytic Hydrogen Production.
Due to its superior morphology, enlarged surface area, and improved photon absorption, the resulted ultrathin silicon nanosheets presented enhanced and visible-light responsive photocatalytic hydrogen generation performance, even without applying any co-catalyst.
Exfoliated near infrared fluorescent silicate nanosheets for (bio)photonics
The development of Egyptian Blue nanosheets with high NIR fluorescence and photostability demonstrating bioimaging applications in vivo and the versatility of EB-NS are reported on.
Liquid Exfoliated SnP3 Nanosheets for Very High Areal Capacity Lithium‐Ion Batteries
Increasing the energy density of lithium‐ion batteries requires the discovery of new electrode materials capable of achieving very high areal capacity. Here, liquid phase exfoliation is used to
Mechanisms of Liquid Phase Exfoliation for the Production of Graphene.
It is demonstrated that during ultrasonic LPE, the transition from graphite flakes to graphene takes place in three distinct stages, which will be of great value in the quest to optimize the lateral dimensions, thickness and yield of graphene and other 2D materials in large-scale LPE for various applications.
Naturally occurring van der Waals materials
The exfoliation of two naturally occurring van der Waals minerals, graphite and molybdenite, arouse an unprecedented level of interest by the scientific community and shaped a whole new field of
Production of Quasi-2D Platelets of Non-Layered Iron Pyrite (FeS2) by Liquid-Phase Exfoliation for High Performance Battery Electrodes.
The synthesis of 2D-platelets from the earth-abundant, non-layered metal sulfide, iron pyrite (FeS2), using liquid-phase exfoliation is reported, which can be used to produce lithium ion battery anodes with capacities approaching 1000 mAh/g.
The Rate Performance of 2D Material-Based Battery Electrodes May Not Be As Good as Is Commonly Believed.
Two dimensional materials show great potential for use in battery electrodes and are believed to be particularly promising for high-rate applications. However, there does not seem to be much hard
Equipartition of Energy Defines the Size-Thickness Relationship in Liquid-Exfoliated Nanosheets.
A simple nonequilibrium thermodynamics-based model predicting that the power-law prefactor is proportional to both the ratios of in-plane-tearing/out-of-plane -peeling energies and in- plane/out of-plane moduli supports the hypothesis that energy equipartition holds between nanosheet tearing and peeling during sonication-assisted exfoliation.
