Oxidation promoted osmotic energy conversion in black phosphorus membranes. [PDF]

Proc Natl Acad Sci U S A, 2020
Significance Engineering two-dimensional (2D) membranes has been an effective approach to boost the harvesting of the “blue” osmotic energy between river water and sea water. Here we show the oxidation of black phosphorus (BP) can be fully utilized for osmotic energy conversion, which stands in contrast to using ...

Improved Ion Transport in Hydrogel-Based Nanofluidics for Osmotic Energy Conversion [PDF]

ACS Central Science, 2020
In nature, ultrafast signal transfer based on ion transport, which is the foundation of biological processes, commonly works in a hydrogel-water mixed mechanism. Inspired by organisms' hydrogel-based system, we introduce hydrogel into nanofluidics to prepare a hydrogel hybrid membrane.

Two-Dimensional Membranes with Highly Charged Nanochannels for Osmotic Energy Conversion. [PDF]

ChemSusChem, 2022
AbstractInadequate mass transportation of semipermeable membranes causes poor osmotic energy conversion from salinity‐gradient. Here, the lamellar graphene oxide membranes (GOMs) constructed with numerous fusiform‐like nanochannels, that are pre‐filled with negatively charged polyanion electrolytes, to both enhance the ion permeability and ion ...

Lifecycle assessment of membrane synthesis for the application of thermo-osmotic energy conversion process

Case Studies in Chemical and Environmental Engineering
The thermo-osmotic energy conversion (TOEC) process harnesses low-grade waste heat for electricity generation. Key to TOEC is selecting membrane materials, with polyvinylidene fluoride (PVDF) and polytetrafluoroethylene (PTFE) being common choices.
