It is indicated in the thesis that E.M.Forster highlights the failure of aspired understanding between different races, different people and even within a person. In other words, in many cases people have aspirations for understanding, but in reality the real understanding is very difficult to fulfill.展开更多

System dynamics deals with the internal processes that produce good and bad behavior in social, economic, and environmental systems. In a system dynamics study, one builds a computer model that acts out the behavior of the real system being represented. The computer model is then used to展开更多

Thus, the system may respond in different ways to identical experimental conditions which seems to contradict classical thermody-namics. While the phenomenon is known since about a century, it has not yet found a consistent theoretical description. In the pres-ent talk, we will-based on results of computer simulations-formulate rules that provide a consistent basis for the behavior of confined systems, or even for inhomogeneous systems in general. In other words, we present a new theory (confined thermodynamics) with its own definitions and rules. It will turn out, that hysteretic behavior does not impose a conceptual challenge any more, but follows in a natural way from these rules. The approach which is employed in the simulations is very akin to the density functional method. All quantities defined develop into the standard thermodynamic expressions when the density of amount becomes homogeneous.The second part of the talk is devoted to the potential for practical use. It turns out that the new theory does not only remove conceptual problems, but at the same time opens the route to a number of new states found in porous systems which may lead to im-proved applications. In particular we will focus on the possibility to drive a fluid in a pore into exotic states with negative pressure, provided one has full control over the phenomenon of adsorption hysteresis. Negative pressure states are in principal known since the time of Torricelli and they have been in the literature as experimentally accessible situations. Still, they have not been turned into practical usefulness which is likely to be caused by the notion of their metastability in macroscopic systems. However, fluids con-fined to nanopores have been proven to show reproducible behaviour. The present time appears to be suited for exploring the new ap-plications resting in fluid/pore systems: since about a decade material scientists have started to prepare pores with increasing accura-cy from an increasing variety of substances. On the other hand, the new theory presented in the first part of the talk provides the tool to drive a fluid/pore system reliably into any of the exotic states found within a hysteresis loop. Prospects of a few applications will be discussed.展开更多
