“…In addition, the current along the armchair orientation (I a ) increases at 1.0 V and then rapidly decreases and finally reaches a minimum value at 1.6 V, which exhibits a significant NDR effect, which is a nonlinear transport phenomenon in which the ion current decreases with increasing electric potential. [57][58][59][60][61] In addition, I a reaches its maximum of 5.2 Â 10 4 mA mm À1 when V = 1.0 V, as shown in the line of black squares. However, the current grows with increasing bias voltage to a maximum value of 4.8 Â 10 4 mA mm À1 with a bias of 0.6 V along the zigzag direction (I z ), as shown by the line of red circles.…”

In this article, we develop NanoSoft SoftLab GUI circuit model and oscillator model to study the current–time and current–voltage characteristics inside the nanopore membrane. We study the ion transport for silicon nitride sputtered with silicon dioxide (Si3N4–SiO2) nanopore membrane, graphene, and molybdenum disulfide (MoS2) nanopore membrane. Further, we apply our two models to understand the ion transport in two polydimethylsiloxane (PDMS) micropore reservoirs connected in series with no nanopore membrane. Furthermore, we perform circuit simulations on silicon nitride sputtered with silicon dioxide with pore radius varying from nanometer to millimeter to obtain current from pA to μA. Here we develop NanoSoft visualization software to match the silicon nitride nanopore membrane. We develop open‐loop controller model to relate the ionic current in the nanopore to the nanofluidic calculator output. Our work can find applications for energy‐efficient nanofluidic processors and computers to build towards the recent nanofluidic memristive synapse‐like memory dynamics literature.

Salinity gradient energy (SGE), known as blue energy is harvested from mixing seawater with river water in a controlled way using ion exchange membranes (IEMs). Using 2D materials as IEMs improves the output power density from a few Wm−2 to a few thousands of Wm−2 over conventional membranes. In this review, we survey the efforts taken to employ the different 2D materials as nanoporous or lamellar membranes for SGE and provide a comprehensive analysis of the fundamental principles behind the SGE. Overall, this review is anticipated to explain how the 2D materials can make SGE a viable source of energy.

Electrodiffusioosmosis induced negative differential resistance in micro-to-millimeter size pores through a graphene/copper membrane

Abstract: Negative differential resistance (NDR) is one of the nonlinear transport phenomena in which ionic current decreases with the increase in electromotive potential. Electro-osmosis, diffusio-osmosis, and surface charge density of the...
