Early Career: Acquisition of Shared, Basic Biogeochemistry Lab Facilities at Rice University

0949337 Masiello该奖项为NSF提供了36个月的资金，用于在Rice进行碳和养分循环研究的基础地球化学仪器。将购买和安装一台CHNSO固体样品分析仪和一台总碳分析仪。几个研究项目将利用所要求的成套仪器：土壤黑碳库稳定性和热解分析;天然铝硅酸盐纳米颗粒对土壤中碳和养分循环的影响;利用碳和养分分布的全新世南极半岛沉积物中的古气候和古生产力指标;以及生态系统养分循环研究，以评估墨西哥湾沿岸的恢复和减缓努力。除了PI的研究项目外，这些设备还将支持高级环境化学实验室课程。资金被要求赞助两名高中教师通过生物和环境纳米技术水稻中心的夏季计划。仪器将主要由PI管理，但将置于Rice共享设备管理局之下，以确保长期维护。在授标第一年之后，将汇编和评价使用统计数据，以确定合理的成本回收用户费。

0949337MasielloThis award provides NSF funding over 36 months to acquire basic biogeochemistry instrumentation for carbon and nutrient cycling studies at Rice. A CHNSO solid sample analyzer and a total carbon analyzer will be purchased and installed. Several research projects would utilize the requested instrument suite: soil black carbon (BC) pool stability and pryolysis analysis; natural aluminosilicate nanoparticles impacts on carbon and nutrient cycling in soils; paleoclimate and paleo-productivity indicators in Holocene Antarctic Peninsula (AP) sediments using carbon and nutrient distributions; and ecosystem nutrient cycling studies to evalute Gulf coast restoration and mitigation efforts. The equipment, in addition to the PIs' research projects, will support an upper level environmental chemistry lab course. Funds are requested to sponsor two high school teachers for a summer program through the Rice Center for Biological and Environmental Nanotechnology. The instrumentation will be primarily administered by the PI but will placed under the Rice Shared Equipment Authority which will ensure long-term maintenance. Use statistics will be compiled and evaluated for setting reasonable cost-recovery user fees after the first year of the award.***
