2D materials as an emerging platform for nanopore-based power generation

Electric‐Field‐Induced Ionic Sieving at Planar Graphene Oxide Heterojunctions for Miniaturized Water Desalination

“…Actually, the PNP model provides a more precise and quantitative description to the electrostatic‐interaction‐based salt rejection. [ 43 ] Meanwhile, under reverse bias, the salt content in the extracted water is higher than that in the feed solution. Thus, the salt rejection rate is negative, showing concentration effect.…”

Improved osmotic energy conversion in heterogeneous membrane boosted by three-dimensional hydrogel interface

“…The synergistic effect between the two layers with inherent asymmetric structure, charge, and wettability would contribute to novel ionic transport properties such as ionic diode effect [21][22][23] . This nonlinear nanofluidic behavior allows unidirectional ion transport and thus could prohibit the flow of any current back into membrane during the energy conversion process, largely decreasing the dissipation of Gibbs free energy as Joule heat and ultimately enhancing the power generation 14,[24][25][26] . In the past years, diverse heterogeneous membranes including organic/organic, inorganic/inorganic, and organic/inorganic hybrid system have been constructed [27][28][29][30][31] .…”

Wafer‐Scale Fabrication of Nanopore Devices for Single‐Molecule DNA Biosensing using MoS2

“…In the end, we showed the applicability of our devices for biosensing of short 100 bp DNA molecules. In principle, these devices can be used for other exciting applications involving wafer-scale flexible electronics [41,[73][74][75] as well as highly efficient osmotic energy harvesting cells [24] or recently emerged extension of nanopore sequencing-a nanopore field-effect transistors enabling both ionic and transverse current based biomolecule detection. [15,76,77] We believe that further integration and parallelization of nanopore based membrane devices will lead to high-throughput usage [78][79][80][81] and in turn will encourage new, emerging, commercial applications of this technology.…”

“…[12] Furthermore, monolayer MoS 2 nanopore devices are becoming promising tools for emerging scientific applications in defect-engineering research [19][20][21][22][23] and highly efficient blue energy harvesting. [24][25][26] One of the most crucial bottlenecks of monolayer device fabrication is the thin film synthesis and its processing scale. Most reported applications rely on a relatively small monolayer substrate size which enforces a single-chip transfer and fabrication of a single device a time.…”
