9601715 Pingitore This grant provides $111,126 as partial support of the costs of acquiring an X-ray microfluorescence (XRMF) spectrometer. This instrument is comparable to an energy dispersive XRF but has a very narrow collimated X-ray beam which allows non- destructive elemental analyses of geological and archaeological samples at relatively high spatial resolutions (~ 30 microns). Although this instrument is also comparable to an electron microprobe (EMP) in many of its capabilities, the XRMF can handle much larger samples and little to no sample preparation is required making XRMF analyses relatively simple to learn and therefore amenable to undergraduate student involvement. This instrument will be used for a variety of interdisciplinary research topics at this largest Hispanic-majority institution in the U.S. including, non-destructive compositional analyses of rare archaeological artifacts such as pottery shards and bone as indicators of source material locations and thus settlement patterns and dietary habits of ancient civilizations, analyses of the Sr/Ca ratio in growth banded corals as proxies for paleo sea surface temperatures and the analyses of plant tissues for toxic metals in environmental studies. ***

9601715 Pingitore这笔赠款提供了111,126美元，以部分支持获得X射线微荧光（XRMF）光谱仪的成本。 该仪器与能量色散XRF相当，但具有非常窄的准直X射线梁，可以在相对较高的空间分辨率（〜30微米）下对地质和考古样品进行非破坏性元素分析。 尽管该仪器在许多功能中也与电子微探针（EMP）相媲美，但XRMF可以处理更大的样品，几乎不需要样品制备，从而使XRMF分析相对简单地学习，因此可以接受本科生的参与。 This instrument will be used for a variety of interdisciplinary research topics at this largest Hispanic-majority institution in the U.S. including, non-destructive compositional analyses of rare archaeological artifacts such as pottery shards and bone as indicators of source material locations and thus settlement patterns and dietary habits of ancient civilizations, analyses of the Sr/Ca ratio in growth banded corals as proxies for paleo sea surface在环境研究中，温度和植物组织分析有毒金属。 ***
