Benetzungseigenschaften von Pflanzenoberflächen

一滴露珠是如何在植物叶子上形成的？这个问题直接指向了许多生物表面，特别是植物表面惊人的湿润特性。最近，人们对所谓的“荷花效应”产生了极大的兴趣，“荷花效应”指的是几种植物能够把水珠完全吸掉，从而非常有效地洗净叶子。尽管这种影响每天都可以观察到，而且在技术上具有重要意义，但至于有效使用杀虫剂，其基本机制却根本不为人所知。我们想用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.
