1. Plants interact with many organisms, such as microbes and herbivores, and these interactions are likely to affect the establishment and spread of plants. In the context of plant invasions, mycorrhizal fungi and constitutive and induced resistance of plants against herbivores have received attention independently of each other. However, plants are frequently involved in complex multi-trophic ...

Serial femtosecond crystallography (SFX) is capable of collecting three-dimensional single-crystal diffraction data using polycrystalline samples. This may dramatically enhance the power of X-ray powder diffraction. In this paper a test has been performed using simulated diffraction patterns. The test sample is a mixture of two zeolites with crystal grain sizes from 100 to 300 nm. X-ray diffrac...
Ion Microscopy is a powerful technique for intracellular elemental localization in b specimens. The effechve w of this technique depends on the reliability of sample preparation. An ideal Sam le reparation should preserve the chemical and structural integrity of a living cell, and it shouPd ago satisfy the instrumental requirements for analysis. This article critically reviews different methods...
