An Ionic Diode Covalent Organic Framework Membrane for Efficient Osmotic Energy Conversion

ACS Nano, 2022
Heterogeneous membranes that exhibit an ionic diode effect are promising candidates for osmotic energy conversion. However, existing heterogeneous membranes lack molecular-level designed ion channels, thereby limiting their power densities. Here, we demonstrate ionic diode covalent organic framework (COF) membranes with well-defined ion channels ...

Anomalous Channel‐Length Dependence in Nanofluidic Osmotic Energy Conversion

Advanced Functional Materials, 2017
Recent advances in materials science and nanotechnology have lead to considerable interest in constructing ion‐channel‐mimetic nanofluidic systems for energy conversion and storage. The conventional viewpoint suggests that to gain high electrical energy, the longitudinal dimension of the nanochannels (L) should be reduced so as to bring down the ...

Asymmetric membranes for membrane distillation and thermo-osmotic energy conversion

Desalination, 2019
Abstract Asymmetric membranes with a thin, small pore size upper layer have the potential to facilitate a high vapor flux while maintaining high liquid entry pressure, which is critical for membrane distillation (MD) and thermo-osmotic energy conversion (TOEC) processes.

Engineering Low-Resistance Heterogeneous Nanofluidics for Ultrahigh Osmotic Energy Conversion

Journal of the American Chemical Society
Emerging heterogeneous nanofluidics are promising alternatives for harvesting sustainable and clean osmotic energy, primarily due to their capability to reduce Gibbs free energy dissipation. However, the misalignment of nanochannels across different layers in heterogeneous nanofluidics results in low ion flux and high transport resistance, thereby ...

Antiswelling and Mechanical Robustness Clay Membranes Using as Osmotic Energy Conversion

ACS Applied Materials & Interfaces
Clay-based nanofluidic membranes are a promising candidate for osmotic energy conversion (OEC) due to their inherent surface charge that enhances ion selectivity. However, practical applications of these materials were constrained by significant swelling and inferior durability in aqueous environments.

Ionic‐Nanotube Array Membrane Generating Ultrahigh Osmotic Energy Conversion

Advanced Materials
AbstractIon exchange membranes (IEMs) are critical components in osmotic energy conversion. However, traditional IEMs suffer from disordered nanochannels due to the lack of precise control over the content and distribution of ionic groups, resulting in an inherent trade‐off between ion selectivity and conductivity.

Low-Cost and Stable Aramid Nanofiber Membranes for Osmotic Energy Conversion

ACS Applied Materials & Interfaces
Osmotic energy from mixing seawater and river water offers a promising alternative to traditional nonrenewable resources. Harvesting osmotic energy requires the design of ultrathin membranes with high ion selectivity for high ionic conductance. However, lab-scale membranes suffer from high-cost, low mechanical properties, and limited membrane area ...

Ultrathin and Ion-Selective Janus Membranes for High-Performance Osmotic Energy Conversion

Journal of the American Chemical Society, 2017
The osmotic energy existing in fluids is recognized as a promising "blue" energy source that can help solve the global issues of energy shortage and environmental pollution. Recently, nanofluidic channels have shown great potential for capturing this worldwide energy because of their novel transport properties contributed by nanoconfinement.

Giant osmotic energy conversion measured in a single transmembrane boron nitride nanotube

Nature, 2013
New models of fluid transport are expected to emerge from the confinement of liquids at the nanoscale, with potential applications in ultrafiltration, desalination and energy conversion. Nevertheless, advancing our fundamental understanding of fluid transport on the smallest scales requires mass and ion dynamics to be ultimately characterized across an
