NSF Young Investigator

具有化学和取向灵敏度的Ade x射线显微镜研究将在一系列对工业重要的聚合物样品上进行。这些包括，但不限于，亚甲基二苯基二异氰酸酯和甲苯二异氰酸酯基聚氨酯泡沫（陶氏化学），各种纤维，如凯夫拉尔和尼龙（杜邦），以及聚酰亚胺薄膜（杜邦）。我们提出将空间分辨率提高到10 nm，并增加了吸收光谱显微镜的俄歇、二次产率和荧光产率检测模式。% % % * * *

9458060 Ade X-ray microscopy studies with chemical and orientational sensitivity will be performed on a range of polymer samples important to industry. These include, but are not limited to, methylene-diphenyl-diisocyanate and tuluene-diisocyanate based polyurethane foams (Dow Chemical), various fibers such as Kevlar and Nylon (DuPont), as well as polyimide thin films (DuPont). We propose improvements in spatial resolution towards 10 nm and the addition of Auger, secondary yield and fluorescent yield detection modes of absorption spectromicroscopy. %%% ***
