From the granular and fractured subsurface environment to highly engineered polymer membranes used in pharmaceutical purification, porous materials are ubiquitous in nature and industrial applications. In particular, porous media are used extensively in processes including water treatment, pharmaceutical sterilization, food/beverage processing, and heterogeneous catalysis, where hindered mass transport is either essential to the process or a necessary but undesirable limitation. Unfortunately, there are currently no universal models capable of predicting mass transport based on a description of the porous material because real porous materials are complex and because many coupled dynamic mechanisms (e.g., adsorption, steric effects, hydrodynamic effects, electrostatic interactions, etc.) give rise to the observed macroscopic transport phenomena.

纳米颗粒跟踪以探测多孔介质中的运输。

从颗粒状和破裂的地下环境到用于药物纯化的高度工程化的聚合物膜,多孔材料在自然和工业应用中无处不在。特别地,多孔介质广泛用于包括水处理,药物灭菌,食品/饮料加工以及非均相催化在内的过程中,其中受阻的传质对于该过程是必不可少的,或者是必要但不理想的限制。不幸的是,由于实际的多孔材料很复杂,并且由于许多耦合的动力学机制(例如吸附,空间效应,流体动力学效应,静电相互作用等),目前尚无基于多孔材料描述来预测质量传输的通用模型。引起观察到的宏观传输现象。
