论文摘要
水含酒精的混合物具有许多异常的物理化学特性，其起源仍然存在争议。在这里，我们使用透射电子显微镜（TEM），纳米颗粒跟踪分析（NTA）和原子力显微镜（AFM）来研究乙醇 - 水混合物。 TEM揭示了使用水分子形成含有高密度的小细胞的晶体分子的介质覆盖结构。通过NTA测得的405 nm的折射率为1.27+-0.02的折射指数进一步支撑了这些介质覆盖结构，并通过NTA测量了AFM观察值所隐含的介质结构的亲水性质，从而解释了许多与水含水液混合物相关的长期谜题。
Water-alcohol mixtures exhibit many abnormal physicochemical properties, the origins of which remain controversial. Here we use transmission electron microscopy (TEM), nanoparticle tracking analysis (NTA), and atomic force microscopy (AFM) to study ethanol-water mixtures. TEM reveals mesoscopic clathrate structures with water molecules forming a crystalline matrix hosting a high density of tiny cells. The presence of these mesoscopic clathrate structures is further supported by a refractive index of 1.27+-0.02 at 405 nm measured via NTA and the hydrophilic nature of the mesoscopic structures implied by AFM observations, explaining many long-standing puzzles related to water-alcohol mixtures.
