NSF Young Investigator

9458060将对一系列对工业重要的聚合物样品进行具有化学和取向灵敏度的X射线显微镜研究。 这些包括但不限于基于亚甲基-二苯基-二异氰酸酯和甲苯-二异氰酸酯的聚氨酯泡沫（Dow Chemical）、各种纤维如Kevlar和尼龙（DuPont）以及聚酰亚胺薄膜（DuPont）。 我们提出了对10 nm的空间分辨率的改进，并增加了俄歇，二级产量和荧光产量检测模式的吸收光谱显微镜。 %%% ***

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. %%% ***
