This Earth Sciences Instrumentation and Facilities award supports the procurement of a Wavelength Dispersive X-ray Fluorescence Spectrometer (WD-XRF) for California State University, Bakersfield (CSUB), the sole comprehensive university within a 100-mile radius and a designated Hispanic-Serving Institution. The new WD-XRF, an analytical system, assesses complex matrix materials with a broad spectrum of light and heavy elements, ranging from trace to high concentration levels. The acquisition of this new instrument will enhance research capabilities across diverse disciplines at CSUB, including Geology, Engineering, Environmental Studies, Physics, and Agriculture. It plays an integral role in initiatives aimed at boosting minority student enrollment and retention, elevating educational achievements, and fostering research skills in Science, Technology, Engineering, and Math fields. The instrument also contributes to community outreach efforts, including the high school dual credit program.The new WD-XRF system is one fully automated benchtop XRF, featuring a 12-sample changer and sample spin capability for student use with minimal training. It eliminates the need for cooling water, reducing maintenance and ownership costs. With superior sensitivity and spectral resolution compared to Energy Dispersive XRF spectrometers, it rivals larger WD-XRF systems. Its introduction to CSUB will bring advanced technological capabilities, leading to research advancements in areas including upcycling of mine tailings, polymeric composite materials, agricultural-waste-derived catalysts for energy and resource recovery, paleoceanography, and paleoclimate. Beyond its technical capabilities, the instrument will pave the way for new research directions at CSUB, encouraging collaborative projects among faculty from different departments and facilitating partnerships with researchers from other institutions.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该地球科学仪器和设施奖支持为加州州立大学贝克斯菲尔德分校 (CSUB) 采购波长色散 X 射线荧光光谱仪 (WD-XRF)，该大学是 100 英里半径内唯一的综合性大学，也是指定的西班牙服务中心机构。新型 WD-XRF 是一种分析系统，可评估具有广谱轻元素和重元素（范围从痕量到高浓度水平）的复杂基质材料。收购这款新仪器将增强 CSUB 跨学科的研究能力，包括地质学、工程、环境研究、物理学和农业。它在旨在提高少数族裔学生入学率和保留率、提升教育成就以及培养科学、技术、工程和数学领域研究技能的举措中发挥着不可或缺的作用。该仪器还为社区外展工作做出了贡献，包括高中双学分计划。新的 WD-XRF 系统是一款全自动台式 XRF，具有 12 个样品更换器和样品旋转功能，可供学生使用，只需最少的培训。它无需冷却水，从而降低了维护和拥有成本。与能量色散 XRF 光谱仪相比，它具有卓越的灵敏度和光谱分辨率，可与更大的 WD-XRF 系统相媲美。其加入 CSUB 将带来先进的技术能力，从而推动尾矿升级再造、聚合物复合材料、用于能源和资源回收的农业废物衍生催化剂、古海洋学和古气候等领域的研究进展。除了其技术能力外，该仪器还将为 CSUB 的新研究方向铺平道路，鼓励不同部门的教师之间的合作项目，并促进与其他机构的研究人员的合作。该奖项反映了 NSF 的法定使命，并通过评估被认为值得支持利用基金会的智力优势和更广泛的影响审查标准。
