LExEN: SGER: High-Pressure, Hydrothermal Organic Synthesis: Implementation of the Hydrothermal Diamond Anvil Cell

由于压力对于了解极端环境下生命的可能起源和持续生存的重要性，我们提出了高压、热液有机化学的研究。拟议研究的主要目标是完善原位热液实验技术，并建立地下热液环境中有机合成反应的知识基础——这是研究极端环境中生命的一个公认的需求和机会（Holm等人，1992年明确指出，国家研究委员会，1990年暗示）。为此，我们建议开发和应用光谱方法来监测热液有机反应的速率和途径，作为相关变量的函数，包括压力、温度、pH和H2电池，这种类型已经在地球物理实验室设计、建造和测试过。该项目侧重于高压热液有机反应的现场监测。这项工作涉及热液压力电池、拉曼光谱和光学显微镜的应用，以实时评估有机反应的途径和速率。本项目拟重点开展三项工作：(1)热液金刚石电池的设计与建造；(2)热液有机反应原位监测技术的发展；(3)水热反应研究。

The principal objectives of the proposed research are to refine in-situ hydrothermal experimental techniques and to establish a foundation of knowledge regarding organic synthesis reactions in subsurface hydrothermal environments - a well-recognized need and opportunity in the study of life in extreme environments (stated explicitly in Holm et al., 1992, and implicitly in National Research Council, 1990). Toward this end, we propose to develop and apply spectroscopic methods to monitor the rates and pathways of hydrothermal organic reactions as a function of relevant variables, including pressure, temperature, pH, and H2 cells, of a type that has been designed, built, and tested at the Geophysical Laboratory.The project focuses on in-situ monitoring of high-pressure, hydrothermal organic reactions. This work involves the application of hydrothermal pressure cells, Raman spectroscopy, and optical microscopy to assess pathways and rates of organic reactions in real time. We propose to focus on three tasks during this project: (1) design and construction of hydrothermal diamond cells; (2) development of in situ monitoring techniques to study hydrothermal organic reactions; and (3) hydrothermal reaction studies.
