Influence factors of thermal driven ion transport in nano-channel for thermoelectricity application

Simultaneous thermoosmotic and thermoelectric responses in nanoconfined electrolyte solutions: Effects of nanopore structures and membrane properties

“…In addition, a new mechanism causing a giant TER was found using molecular dynamics simulation; that is, the excess specific enthalpy of water molecules together with the electro-osmotic mobility of solid-liquid interface could give rise to a TER and such a response would be enhanced by large slippage [22]. Recent numerical studies by Zhong and Huang [6,23] showed that there is an optimal length-to-height ratio and optimal temperature difference maximizing the short-circuit current (SCC) and the open-circuit voltage (OCV) of the thermoelectricity in nanoconfined electrolyte solutions. These works motivate efforts to put the electrolyte-based TER to practical use.…”

Blue energy generation by the temperature-dependent properties in funnel-shaped soft nanochannels

“…Special attention is placed on the thermal response of the electrolyte solution: positive and negative ions travel along the temperature gradient, generating a thermoelectric field that operates on the ionic species. 71,72…”

Influence of viscoelectric effect on diffusioosmotic transport in nanochannel

“…Pertaining to nanofluidic Abbreviations: DOF, diffusioosmotic flow; EDL, electric double layer. transport, although several flow actuation mechanisms, such as capillary action [6], electroosmotic driven [5,7], pressure driven [8], concentration gradient-induced actuation [9][10][11], and temperature gradient-modulated flow [12,13], have established their pertinence, diffusioosmotic flow (DOF), equivalently, diffusioosmosis is reckoned as a promising actuation parameter as well [14][15][16][17]. It is worth mentioning here that sometimes DOF mechanism is also referred to as the combined electroosmotic [18][19][20][21][22][23] and chemical gradient induced flow mechanism [11].…”

“…A vast range of practical applications in emerging areas, for example, energy harvesting, biochemical process, ionic sensors, biosensors, and advanced drug‐delivery devices—to name a few—alongside rich physics involved with the underlying transport processes have motivated researcher to deeply focus on the nanofluidics with a great deal of interests in recent years [1–5]. Pertaining to nanofluidic transport, although several flow actuation mechanisms, such as capillary action [6], electroosmotic driven [5, 7], pressure driven [8], concentration gradient–induced actuation [9–11], and temperature gradient–modulated flow [12, 13], have established their pertinence, diffusioosmotic flow (DOF), equivalently, diffusioosmosis is reckoned as a promising actuation parameter as well [14–17].
