Mesoporous silicon accommodating structured nano-channels is employed as a host material for recording the evolution of liquid–vapor phase transitions in nanoporous materials upon molecular adsorption and desorption. Analysis is based on the application of micro-imaging via IR microscopy revealing the spatial-temporal dependence of guest concentrations within the material as a function of the chosen pressure steps. In this way, phase transitions become observable in the context of their local environment and may be correlated with the pore architecture by immediate experimental evidence.

纳米通道中液相-汽相转变的微成像

容纳结构化纳米通道的中孔硅被用作主体材料，用于记录分子吸附和解吸后纳米孔材料中液相汽相转变的演变。分析是基于通过IR显微镜进行的显微成像分析，揭示了材料中客体浓度随所选压力阶跃而变化的时空相关性。以这种方式，相变在其局部环境的情况下变得可观察到，并且可以通过立即的实验证据与孔结构相关联。
