Abstract

There has been considerable scientific interest in comprehending the behavior and phase transitions of HO at the nanoscale in low temperatures. Herein, a highly sensitive and nondestructive surface plasmonic detection system operated at low temperatures to investigate the real-time nanoscale variation in HO density from a rapidly cooled thin ice layer formed at 77 K is employed. The nanoslit device exhibits a distinct plasmonic response at 180-250 K, correlated to an increase in the local density of HO at the nanometer scale. Along with theoretical analyses, it is revealed that high-density HO clusters form by vigorous aggregation of HO molecules within the interphase liquid region between polymorphic ice crystals. The utilization of ice-active materials, known to inhibit ice growth, suppresses the initiation of such high-density nanoclustering at 180 K. These results contribute to the comprehension of the interplay between polymorphic crystals and density-variant interphases in low-temperature HO systems.

摘要

在低温下理解纳米尺度的羟基（HO）行为和相变一直是科学界相当感兴趣的课题。在此，采用了一种在低温下运行的高灵敏度、无损表面等离子体检测系统，以研究在77K下快速冷却形成的薄冰层中HO密度的实时纳米尺度变化。纳米狭缝装置在180 - 250K时表现出明显的等离子体响应，这与纳米尺度上HO局部密度的增加相关。结合理论分析表明，高密度HO簇是由多晶型冰晶之间的相间液体区域内HO分子的剧烈聚集形成的。已知能抑制冰生长的冰活性材料的使用，在180K时抑制了这种高密度纳米团簇的形成。这些结果有助于理解低温HO系统中多晶型晶体与密度可变相间之间的相互作用。
