Nanotubes for Osmotic Energy Harvesting

ECS Meeting Abstracts, 2014
New paradigms for fluid transport are expected to emerge from the confinement of liquids at the nanoscales [1- 3], with potential breakthroughs in ultra-filtration, desalination, and energy conversion [4]. Nevertheless, advancing the fundamental understanding of fluid transport at the smallest scales requires mass and ion dynamics to be ultimately ...

The osmotic virial formulation of the free energy of polymer mixing

The Journal of Chemical Physics, 2015
We derive an alternative formulation of the free energy of polymer mixing in terms of an osmotic virial expansion. Starting from a generalized free energy of mixing, and the assumption that the internal energy of mixing is analytic in the polymer composition variable, we demonstrate that the free energy of mixing can be represented as an infinite ...

Osmotic desalination by solar energy: A critical review

Renewable Energy, 2019
Abstract This review deals with the membrane desalination techniques, reverse and forward osmosis, run by solar energy. Photovoltaic panels and solar thermal collectors are favorable substitutes for fossil fuels, which are being plundered and cause climate changes.

Robust Membrane for Osmotic Energy Harvesting from Organic Solutions

ACS Applied Materials & Interfaces, 2020
Using particulate nanochannels for desired ions transport is a potential technology for nanofluidic osmotic energy harvesting. However, the finite fresh water as an essential part of this harvesting system limits its development. Therefore, developing a robust membrane for harvesting energy from other solutions such as waste organic solutions is ...

Osmotic Energy Conversion Techniques from Seawater

2010
This paper firstly introduces the principles of Pressure Retarded Osmosis (PRO) and Reverse Electro Dialysis (RED). It is concluded that the RED method is more suitable than the PRO method for power generation from seawater. Theoretical analysis of RED stack is made for the design of a test RED compartment.

Osmotic Energy

The phenomenon of osmosis is demonstrated by carrying out the experiment shown schematically in Figure 6.1. We consider a jar separated into two compartments by a dense porous wall. The membrane is semi-permeable: it allows the passage of water but it retains very small particles, such as ions.

Energy Metabolism and Osmotic Acclimation in Teleost Fish

2007
This chapter focuses on different types of tissues, such as: tissues involved directly in osmoregulatory work such as gills, kidney and intestine; and tissues involved indirectly in osmoregulatory work, providing fuels to other tissues such as the case of plasma and liver.
