臺灣博碩士論文加值系統

本論文分為兩部分,第一部份為利用X光繞射協助清華大學化學系教授趙桂蓉老師分析中尺度二氧化矽孔洞(MCM41)薄膜的結構.趙桂蓉老師將C16EO10(模板劑的前驅物),以浸渍塗佈(dip-coating)的方式,塗佈在矽晶片(100)的表面,並加以熱處理,形成中尺度二氧化矽孔洞薄膜.本論文利用X光徑向(θ-2θ)掃描, X光平面(α-β)掃描,X光掠角繞射(GID)影像等方式,分析薄膜結構.我們發現孔洞薄膜同時有兩種結構存在,孔洞薄膜會形成二維晶格,但從穿透式的X光繞射圖形出現繞射環的情形來看,並沒有特定的排列方向.
第二部份為大分子X光繞射用之CCD測試,利用同步輻射光源配合高精度八環繞射儀,收集溶菌脢蛋白質分子之X光繞射圖形.文中並將描述此套儀器及軟體操作說明.此部份尚在測試儀器的階段.

Thesis contain two parts, the firt part utilize grazing incidence small angle x-ray scattering (GISAXS)to study the structure of the mesopoeous tube thin film (MCM-41), the thin film contains two structure, one is face-center rectangular and the other is rectangular.No prefered orientaqtion.
The second part test the ability of CCD to collect the x-ray diffraction patteren of macromolecular (lysozyme)in national synchron radiation research center. The data quality is very good.
