Fate of (metal)organics under extreme conditions: survival and relevance for prebiotic chemistry (P02)

在地质阶段的有机物和金属有机物的存在和稳定性是一个巨大的信息来源的潜力，为地球外与地球来源的基本成分的起源的生命前的化学。陨石中的碳基分子可以在小行星母体历史上的恶劣外星条件下生存下来，在大气进入地球表面期间，以及在它们驻留在高能量的早期地球表面期间。特定有机物在暴露于电、热和冲击应力下的生存，一定在早期的生命前化学和地球上生命的出现中发挥了重要作用。该项目的重点是金属有机物在模拟此类系统的实验条件下的稳定性。

The presence and the stability of organics and metalorganics at geological phases are a vast source of information on the potential for extraterrestrial versus terrestrial sources of essential ingredients for the genesis of prebiotic chemistries. Carbon-based molecules in meteorites can survive harsh extraterrestrial conditions within the asteroid parent body´s history, during atmospheric entry to the Earth’s surface and during their residency on a highly energetic early Earth´s surface. The survival of specific organic matter when exposed to electrical, thermal and shock stresses, must have played a major role in the early prebiotic chemistry and the emergence of life on Earth. This project focuses on the stability of metalorganics in experimental conditions mimicking such systems.
