Fluids in Mesopores: A New Theory and Applications

摘要: While hysteresis in the adsorption of fluids porous material is known since about one century, thermodynamic treatment this phenomenon still not settled. We propose to accept that thermodynamics designed deal with confined systems and we introduce a new set rules for describing behavior systems. This proposal based on large number simulation calculations. The employed method has been shown describe static dynamic phenomena encountered field. newly formulated theory incorporates without inconsistencies. Further, it will be allows simulating diffusional convectional transport (nanofluidics) by unified approach need capillary forces (surface or interface tensions) phenomenological parameters. second part paper devoted potential practical use. It turns out concepts open route employing unusual states matter found which may lead improved applications. In particular focus possibility drive fluid pore into negative pressure under conditions. can reproducibly controlled. Negative are principal time Torricelli they have discussed literature as experimentally accessible situations. Still, turned usefulness likely caused notion their metastability macroscopic Possible applications refer controlling chemical reactions well routes efficient separation processes difficult handle conventional techniques.
