    This paper proposes a new encapsulation structure for aluminum nitride-based deep UV light-emitting diodes (DUV-LEDs) and eutectic flip chips containing polydimethylsiloxane (PDMS) fluid doped with SiO2 nanoparticles (NPs) with a UV-transparent quartz hemispherical glass cover. Experimental results reveal that the proposed encapsulation structure has considerably higher light output power than the traditional one. The light extraction efficiency was increased by 66.49% when the forward current of the DUV-LED was 200mA. Doping the PDMS fluid with SiO2 NPs resulted in higher light output power than that of undoped fluid. The maximum efficiency was achieved at a doping concentration of 0.2wt%. The optical output power at 200mA forward current of the encapsulation structure with NP doping of the fluid was 15% higher than that without NP doping. The optical output power of the proposed encapsulation structure was 81.49% higher than that of the traditional encapsulation structure. The enhanced light output power was due to light scattering caused by the SiO2 NPs and the increased average refractive index. The encapsulation temperature can be reduced by 4 degrees C at a driving current of 200mA by using the proposed encapsulation structure.

    This study shows that aerosol-assisted dielectric-barrier-discharge atmospheric-pressure plasma deposition (AAAPPD) is a rapid and reagent-free method to entrap proteins on different substrates for biosensor fabrication, and the proteins were not damaged. AAAPPD involves depositing plasma-polymerized ethylene (ppE) with grafted hydroxyl functional groups and embedding the protein in the ppE in one step, making the protein entrapment faster than conventional methods and without using reagents. In this study, SEM and XPS show that more protein deposited near the inlet. Electrophoresis, temperature analysis, and immunostaining respectively demonstrated that the protein maintained its integrity, was unheated, and exhibited activity during AAAPPD. The immunostaining results of AAAPPD protein was close to that of covalent-bonded protein. AAAPPD also entraps protein on three different biosensor substrates.

    A flexible atmospheric-pressure gas ionization sensor (GIS) with the horizontally aligned carbon nanotube (HACNT) electrodes in the planar structure has been demonstrated for the first time via the proposed rolling-down technique of CNTs. The gap between the electrodes of high-density and uniform HACNTs could be therefore precisely controlled via adjusting the length of the CNTs and the interspacing between the patterned catalysts. High-performance sensing characteristics to various gases Ar, N-2, air, and O-2 at atmospheric pressure with the breakdown voltages as low as 160, 193, 205, and 233, respectively, have been achieved with the electrode gap of 20 mu m. It is attributed to the field enhancement from the small gap and the double-side nanostructures. The superior flexibility of the proposed GIS with different bending tests has also been obtained. It reflects that the HACNTs possess excellent material properties, including great mechanical strength and good electrical conductivity. Such a simple, low-cost, and flexible GIS is promising for its applications in portable and wearable personal monitoring devices.

    人工受孕是不孕症患者的一大福音，如何篩選出最好的精子以供卵子受孕是重點之 一，而目前的人工受孕治療技術中，精子的篩選仍是問題之ㄧ。就現有的篩選方法而言， 對於人工受孕(IUI)來說篩選率過低，這會導致成功率的下降。而顯微注射法(ICSI)中， 問題在於無法準確的挑出最好的精子。本計劃之目的在於改善現有的人工受孕技術，目 標為利用全像光學鑷夾(holographic optical tweezers, HOT)系統研發準確的單一精子分離 技術，改善ICSI 的精子篩選過程；利用三維的微流道篩選出所有具有泳動力之精子， 提高精子篩選率，使IUI 成功機率上升。最後，依據醫院的需求做改善，以求應用之實 用性。各年目標略述如下： 第一年： 旨在研發準確的單一精子分離技術。此技術的重要性在於我們可以在 一群精子或是雜碎組織中，準確且快速的單獨分離出一個目標精子，使用 HOT 系統並以目標精子為中心，清空其四週，並用微吸管吸出，達成準確 且單一分離之目的，此種用微吸管吸出的應用方式符合目前醫院的操作過 程，希望可以改善目前TESE 與ICSI 所遇到的問題。 第二年： 目的在解決IUI 中精子數量不夠導致成功率不高的問題，利用三維的 微流道設計以篩選出更多的具活動力之精子，提高篩選率，期待能達成高 篩選率之目標。 第三年： 承續前兩年，為了使我們開發的技術更貼合醫院的應用，第三年計畫 將針對這些計畫做改良與近一步檢驗。 改良部分首先考慮醫院的需求，HOT 的單一精子分離中，預計縮小 系統之體積，使用光纖傳導雷射光減少光路的耦合，達到方便且可攜之目 的。高篩選率三維流道的改良方向，則是取決於當下醫院的看法。 檢驗部分，首先檢驗單一精子分離系統中雷射造成之光傷害，比較 1064nm 與980nm 光傷害的差異，找出最好的波長；此外我們將藉由改變 培養液之折射率，使其折射率高於精子，精子得以被推離光焦點，雷射光 穿過精子的比例變少以降低雷射鑷夾之光傷害。 高篩選率的三維流道方面，我們將做更進一步的分析，方法可以有 泳動速度、活化比例、頂體反應比例、IVF 比例、精子表面的AFM 分析 等，利用這些參數檢驗精子的品質，期待得到此種方法篩選出的精子品質 皆佳的結果。

    The objective of this study is to develop a micro proton exchange membrane fuel cell (PEMFC) stack, in which a flow field plate in each cell is made of polydimethyl-siloxane (PDMS) and manufactured by micro-molding technology. A four-cell micro PEMFC stack in series with a volume of 12 cm x 4.5 cm x 1.2 cm is constructed and tested. The active area of a membrane electrode assembly (MEA) is 2 cm x 2 cm in each individual PEMFC, and the platinum loadings at anode and cathode are 0.3 and 0.5 mg/cm(2), respectively. A series of performance experiments were carried out. Experimental parameters included clamping force and fuel supply condition. Durability tests were carried out as well. Experimental results showed that an appropriate clamping torque range should be considered carefully to enhance performance without narrowing down fuel flow channels. Under a torque of 2.0 kgf . cm, peak power density for this stack is 122.5 mW/cm(2) at 2.0 V. Increase in fuel flow rate is not the best way to improve concentration polarization in this air-breathing stack experiment because of limited air supply, and each cell in the same stack has a different performance under the present arrangement. At present, such stack can maintain a stable power output for a long time (up to 14 hours).
