Item type:Item, 郭芝苑 談台灣音樂困境(2008-04-30) ;沈昭邦 ;Department of Communication and Technology傳播與科技學系從郭芝苑合唱團來交大演出看台灣現代音樂發展困境Item type:Item, Item type:Item, Chemical formation of palladium-free surface-nickelized polyimide film for flexible electronics(2008-04-30) ;Hsiao, Yu-Sheng ;Whang, Wha-Tzong ;Wu, Sheng-Chang ;Chuang, Kuen-Ru材料科學與工程學系Flexible polyimide (PI) films for flexible electronics were surface-nickelized using a fully solution-based process and excellent adhesion between the nickel and polyimide phases was observed. Polyimide substrates were modified by alkaline hydrolysis, ion exchange, reduction and nickel electroless deposition without palladium. Atomic force microscopy and field emission scanning electron microscopy were used to follow the growth of nickel nanoparticles (Ni-NPs) and nickel layers on the polyimide surface. The surface resistances of the Ni-NPs/PI films and Ni/PI films, measured using a four-point probe, were 1.6x10(7) and 0.83 Omega/cm(2), respectively. The thicknesses of Ni-NPs and the Ni layer on the polyimide surface were 82 nm and 382 nm, respectively, as determined by transmission electron microscopy, and the Ni layer adhered well to PI, as determined by the adhesive tape testing method.

We present an efficient hybrid ECME-NR algorithm for the computation of maximum-likelihood estimates of parameters. A score test statistic for testing the existence of skewness preference among random effects is developed. The technique for the prediction of future responses under this model is also investigated. The methodology is illustrated through an application to Framingham cholesterol data and a simulation study.

C. ;Tu, G. C. ;Hung, Caryat C. Y. ;Huang, C. A.Rei, M. H.A novel electroplating method of preparing Pd-membrane on an AISI 316L porous stainless steel support is successfully developed by proper control of rotation speed of the support. The use of low-current density with high-rotation speed enables us to avoid hydrogen absorption during electroplating and to prepare smooth thin surfaced membrane with defect free. The electroplated-Pd-membrane shows well property in the hydrogen permeation, flux and excellent permselectivity (H-2/He > 100,000), and is used in a membrane-assisted steam reformer of methanol for the production of high-purity hydrogen. It was also found that the membrane spontaneously exhibited to resist hydrogen embrittlement under the phase-transition temperature of 280 degrees C, when operated in the temperature range of 250-350 degrees C under the hydrogen pressure of 9 kgf/cm(2).
