Ionic thermal up-diffusion in nanofluidic salinity-gradient energy harvesting. [PDF]

Natl Sci Rev, 2019
Abstract Advances in nanofabrication and materials science give a boost to the research in nanofluidic energy harvesting. Contrary to previous efforts on isothermal conditions, here a study on asymmetric temperature dependence in nanofluidic power generation is conducted. Results are somewhat counterintuitive.
