This award will be used to purchase components for the upgrade of a solid-state 300 MHz nuclear magnetic resonance spectrometer (NMR) for the analysis of environmental samples at Baylor University. The NMR facility will be part of the Geology Department?s organic geochemistry laboratory. The purchase of a solid-state probe with cross-polarization and magic angle spinning will facilitate the acquisition of NMR spectra for nuclei of low abundance in geomedia (e.g. 13C and 15N)?providing information on the structure, identity, and molecular dynamics of the organic matter in modern and ancient soil and sediment. NSF funds will be used to establish an NMR summer school ? an internationally-publicized short-course intended to equip students in the Earth and environmental sciences with the technical expertise necessary to apply NMR spectroscopy to their research interestsThe solid-state NMR facility will support the research of Baylor faculty and students in the department of geology as well as 3 interdisciplinary initiatives: the terrestrial paleoclimate research group (7 faculty members), the institute of ecological, Earth, and environmental sciences (19 faculty members), and the center for reservoir and aquatic systems research (19 faculty members). Research areas that will immediately benefit from the access to the NMR facility include: 1) characterizing the oxidation state of global soil carbon pools and the response of ecosystem oxidative ratio to climate change, 2) assessing the impact of developing-world land use on the quality of riverine organic matter delivered to the oceans (NSF GEO OCE-funded), 3) developing ecosystem biochemical inventories as a tool for understanding soil carbon dynamics, 4) development and validation of a paleo-fire temperature proxy for studying the role of fire in the Earth system, 5) application of the paleofire temperature proxy to several NSF-EAR funded studies of Pleistocene -Holocene climate variability using paleosol records 6) calibrating the paleosol CO2 barometer for vertic paleosols by monitoring carbon cycling in modern Vertisols (NSF EAR-funded), 7) elucidating mechanisms of natural organic matter interactions with nanoscale mineral particles, and 8) investigations of the aggregate structure in melanins.Solid-state nuclear magnetic resonance (NMR) is a powerful analytical tool capable of non-invasively extracting a host of chemical structure information from environmental samples (soil, sediment, biomass, etc). However, NMR spectroscopy remains underutilized in the geosciences because it is not a part of traditional Earth and environmental science curricula. Baylor University has recently undertaken several major initiatives to meet the society?s increasing need for scientists with interdisciplinary training in the Earth and environmental sciences with the establishment of a terrestrial paleoclimate research team, a PhD-granting institute in the ecological, Earth, and Environmental systems (TIEEES), and a center for reservoir and aquatic systems research (CRASR). We propose the establishment of a facility that would give the faculty and students participating in these programs access to solid-state NMR spectroscopy for geological, biogeochemical, and environmental studies. The solid-state NMR facility will be integrated into Baylor University?s Advanced Instrumentation Workshop, which is held annually for student and faculty from the area?s small colleges. Additionally, NSF funds will be used to establish an NMR summer school ? an internationally-publicized short-course intended to equip students in the Earth and environmental sciences with the technical expertise necessary to apply NMR spectroscopy to their research interests. The intended outcome of the proposed research is to help the geoscience community utilize an undeveloped geoanalytical capability that exists at many major research institutions.

该奖项将用于购买用于升级300 MHz核磁共振光谱仪（NMR）的组件，以分析贝勒大学的环境样品。 NMR设施将成为地质部有机地球化学实验室的一部分。购买具有交叉极化和魔法角度旋转的固态探测器将有助于获得NMR光谱，以获取GEOMEDIA低丰度的核（例如13C和15N）？提供有关现代和古代土壤和旧土壤和沉积物的结构，身份和分子动力学的信息。 NSF资金将用于建立NMR暑期学校吗？国际公开的短道旨在使地球和环境科学的学生配备将NMR光谱副本应用于其研究所需的技术专业知识（19位教职员工）和水库和水生系统研究中心（19位教职员工）。 Research areas that will immediately benefit from the access to the NMR facility include: 1) characterizing the oxidation state of global soil carbon pools and the response of ecosystem oxidative ratio to climate change, 2) assessing the impact of developing-world land use on the quality of riverine organic matter delivered to the oceans (NSF GEO OCE-funded), 3) developing ecosystem biochemical inventories as a tool for understanding soil carbon dynamics, 4) development and validation of a paleo-fire temperature proxy for studying the role of fire in the Earth system, 5) application of the paleofire temperature proxy to several NSF-EAR funded studies of Pleistocene -Holocene climate variability using paleosol records 6) calibrating the paleosol CO2 barometer for vertic paleosols by monitoring carbon cycling in modern Vertisols (NSF EAR-funded), 7)阐明天然有机物与纳米级矿物颗粒的相互作用的机制，以及8）对黑色素中骨料结构的研究。Solid-State核磁共振（NMR）是一种强大的分析工具，能够非侵入性地从环境样品（土壤，沉积物，生物群等）中提取大量化学结构信息。然而，在地球科学中，NMR光谱学仍然不足，因为它不是传统地球和环境科学课程的一部分。贝勒大学（Baylor University）最近采取了几项重大举措，以实现地球和环境科学跨学科培训的科学家的需求，并建立了陆地古气候研究团队，这是一个生态，地球和环境系统（菲尼斯）的博士学位授予研究所，以及Reservoir和水上系统研究中心（Crastic and Aqualation和Crasatic和Crasress（Crasr））。我们建议建立一个设施，该设施将使教职员工和学生参与这些计划，访问固态NMR光谱，以进行地质，生物地球化学和环境研究。 固态NMR设施将集成到贝勒大学的高级仪器研讨会上，该研讨会每年针对该地区小型大学的学生和教职员工举行。此外，NSF资金将用于建立NMR暑期学校吗？国际公开的短菜旨在为地球和环境科学的学生提供将NMR光谱范围应用于其研究兴趣所需的技术专长。拟议研究的预期结果是帮助地球科学界利用许多主要研究机构中存在的未开发的地理分析能力。
