摘要

因此，描述液滴、气泡和液膜特性的科学--即皮埃尔-西蒙-拉普拉斯（Pierre-Simon Laplace）在十九世纪初开创的毛细现象--的意义已经超越了我们的星球。毛细管原理的核心是界面张力的概念：从本质上讲，界面张力是液体表面与蒸汽或固体接触时的过剩自由能。界面能的平衡决定了液柱在狭窄的毛细管或孔隙中上升的高度，也决定了液滴在固体基底上扩散或收缩成珠的程度（润湿行为）。即使颗粒的密度比液体大，表面张力也能将小颗粒固定在液体表面，例如铁屑漂浮在水面上。这一过程对于与水有较大接触角的物质来说是有利的，这使得像恩克拉多斯冰壳下的液态海洋表面很可能成为疏水性有机颗粒的聚集地--正如最近在冰壳喷射出的冰羽流中观察到有机大分子后提出的那样2。浮选也可以为有机物的浓缩提供一种途径，从而产生前生物影响。

期刊介绍： Nature Materials is a monthly multi-disciplinary journal aimed at bringing together cutting-edge research across the entire spectrum of materials science and engineering. It covers all applied and fundamental aspects of the synthesis/processing, structure/composition, properties, and performance of materials. The journal recognizes that materials research has an increasing impact on classical disciplines such as physics, chemistry, and biology. Additionally, Nature Materials provides a forum for the development of a common identity among materials scientists and encourages interdisciplinary collaboration. It takes an integrated and balanced approach to all areas of materials research, fostering the exchange of ideas between scientists involved in different disciplines. Nature Materials is an invaluable resource for scientists in academia and industry who are active in discovering and developing materials and materials-related concepts. It offers engaging and informative papers of exceptional significance and quality, with the aim of influencing the development of society in the future.
