An experimental Investigation of Active NanomaterialsBy Yu QiaoAbstractAccording to a recently carried out pioneering study by the author of this proposal, in a system consisting of a nanoporous material immersed in a liquid, as the electrical potential difference or temperature varies, the liquid-solid interfacial energy can be changed significantly. Consequently, the liquid would "flow" into or out of the nanopores, resulting in a considerable system volume change. Because of the ultrahigh specific surface area of the nanoporous material, the energy density associated with the volume variation can be much higher than that of conventional intelligent materials. In the proposed study, we will perform comprehensive research in this area. A number of promising systems will be investigated through volume memory testing. The results will have both immediate and long-term impacts on fundamental research and engineering practices.

活性纳米材料的实验研究根据作者最近进行的一项开创性研究，在由浸入液体中的纳米孔材料组成的体系中，随着电势差或温度的变化，液-固界面能会发生显著变化。因此，液体会“流入”或流出纳米孔，导致相当大的系统体积变化。由于纳米多孔材料具有超高的比表面积，与体积变化相关的能量密度可以比传统的智能材料高得多。在拟议的研究中，我们将在这方面进行全面的研究。许多有希望的系统将通过卷存储器测试进行调查。这些结果将对基础研究和工程实践产生直接和长期的影响。
