Reverse electrodialysis in bilayer nanochannels: salinity gradient-driven power generation
Physical Chemistry Chemical Physics, 2018To evaluate the possibility of nano-fluidic reverse electrodialysis (RED) for salinity gradient energy harvesting, we consider the behavior of ion transportation in a bilayer cylindrical nanochannel with different sized nanopores connecting two reservoirs at different NaCl concentrations.

Salinity gradient power generation in sinusoidal nanochannels
Physics of FluidsSalinity gradient power generation based on nanochannels has drawn much attention for its green and sustainable advantages. However, previous studies have tended to focus on regularly shaped nanochannels, while rough and irregular surfaces are naturally formed during the preparation of nanochannels (similar to sinusoidal nanochannels). In this paper, a

Development of a salinity gradient power: upwelling tests using FLIP
Oceans '04 MTS/IEEE Techno-Ocean '04 (IEEE Cat. No.04CH37600), 2005A series of upwelling experiments were conducted onboard the research platform FLIP in May 2004 off San Diego, California. The objective was to test the relationship between pipe length and seawater entrainment or exit velocity towards development of a salinity gradient power source.

Scale-up characteristics of membrane-based salinity-gradient power production
Journal of Membrane Science, 2015Abstract The controlled mixing of streams with different salinity is a potential route for clean and renewable base-load power generation. Here, a comprehensive process model has been developed for pressure-retarded osmosis (PRO) accounting for full-scale system losses such as viscous dissipation, external mass transfer and equipment efficiency. Also,

Sulfonated Sub-Nanochannels in a Robust MOF Membrane: Harvesting Salinity Gradient Power
ACS Applied Materials & Interfaces, 2019We developed a robust, crack-free ultrathin zeolite- imidazole framework (ZIF-8) membrane in-built with a sulfonate-ion-containing polymer (ZIFHep) via a vapor-assisted in situ conversion process. The sulfonated sub-nanochannels of the ZIFHep membrane afforded a rapid and selective transport of Li+ over counteranions and other alkali ions due to ...
