标题： Adsorption desorption processes on mesoscopic pores conected to microscopic pores of complex geometry using the Ising model

摘要： 在本工作中，我们报告了使用三维伊辛模型的计算机模拟研究氮气在固体表面上的吸附和脱附过程，针对具有复杂多孔结构的介观和微观层次的系统。 吸附和脱附过程之间出现了一条滞后循环，并且我们发现其特性取决于孔的几何形状以及表面与流体相互作用的强度。 我们还获得了平均吸附等温线，该等温线代表了不同形状孔的组合，并由于孔的结构在某些化学势值处表现出稳健的跳跃。 最后，我们将结果与实验数据进行了比较，并报告了与介孔相连的微观孔的填充过程。 我们认为这些预测对从事石油增强采收率的研究人员以及新纳米材料的设计者等具有重要意义。 显示英文摘要

摘要： In this work we report studies of nitrogen adsorption and desorption onto solid surfaces using computer simulations of the three dimensional Ising model, for systems with complex porous structures at the mesoscopic and microscopic levels. A hysteresis cycle between the adsorption and desorption processes appears and we find that its characteristics are dependent on the geometry of the pore and on the strength of the surface fluid interaction. We obtained also an average adsorption isotherm, which represents a combination of differently shaped pores, and shows robust jumps at certain values of the chemical potential as a consequence of the structures of the pores. Lastly, we compare our results with experimental data and also report the filling process of microscopic pores connected with mesopores. It is argued that these predictions are useful for researchers working on the enhanced recovery of oil and for the design of new nanomaterials, among others.
