Benetzungseigenschaften von Pflanzenoberflächen

一滴露水是如何在植物的叶子上形成的？这个问题直接指向了许多生物表面令人惊叹的润湿特性，特别是植物。最近，他们对所谓的“莲花效应”产生了极大的兴趣，即几种植物能够使水珠完全脱落，从而非常有效地洗掉叶子。虽然这种效应可能每天都能观察到，并且具有重要的技术意义，但对于杀虫剂的有效使用，其基本机制却完全不清楚。我们希望通过近年来发展起来的现代实验工具来研究这些机制。

How does a drop of dew form on a plant leaf? This question points directly to the amazing wetting properties of many biological surfaces, in particular plants. They have received great interest recently in connection with the so-called "lotus-effect", i e the ability of several plants to make water bead off completely and thereby wash the leaf very effectively. Although this effect may be observed every day and is of great technological importance, as for the effective use of insecticides, its basic mechanisms are not at all understood. We want to investigate these mechanisms by means of the modern experimental tools which have been developed in recent years.
