  1. 未來的奈米世界

  2. 奈米醫學 (Nano Medicine) • 奈米光電(Electro-Optics Technology) • 奈米能源科技(Nanoenergy technology)

  3. 奈米醫學的研究方向 • 醫學用奈米材料 • 奈米顆粒 、藥物設計、組織工程、DNA定序 • 生物元件 • 生物工程改造病毒、生物工程改造細菌 • 醫學用奈米機械 • 生物電腦、奈米馬達

  4. 奈米電子(Nanoelectronics) • Carbon Nanotubes • Molecular Devices  • Nanomagnetics for ultra-dense storage  • Photonic Crystals 

  5. 奈米碳管(Carbon Nanotubes)  Carbon nanotubes are extremely thin (their diameter is about 10,000 times smaller than a human hair), hollow cylinders made of carbon atoms.

  6. 奈米碳之應用 Carbon Nanotubes: Compression, Bending, and Twisting Biomimetic Computing and Logic Architecture Based on "Y-Branched" Carbon Nanotubes Carbon Nanotube: Etching, Indentation

  7.   Building Carbon Nanotube Transistors IBM scientists developed a breakthrough transistor technology that could preview how computer chips can be made smaller and faster than what is currently possible with silicon.

  8. Molecular Devices  Nanogears like these may replace current manufacturing processes. http://www.static.howstuffworks.com/gif/ nanotechnology-nasa.jpg Carbon Nanotube Gears

  9. Nanosystems has excellent black-and-white images of molecular structures. These images typically show a structure with a few dozen to a few thousand atoms, where each atom is a sphere. The different element types are shown by using different levels of gray. Several of the color images below show molecular structures that are similar or identical to structures illustrated in Nanosystems. The captions for the black and white images in Nanosystems provide useful documentation for the corresponding color images.

  10. A second very popular image from Nanosystems is the bearing illustrated on page 296. The caption on page 296 and the text on page 297 provide background information about the bearing and what it does. Several high resolution images of this bearing are available:

  12. 光電科技與相關科技之關係 何謂『光電』？ 『光電』一詞來自美國Electro-Optics Technology 日本及歐洲一些國家稱之為Opto-Electronics Technology 法國稱之為Photonics Technology 光電科技結合光學和電子學，將傳統光學、量子學、電子學結合在一起，進而應用到各種領域。

  13. 光電產品－系統類

  14. 光電產品－元件類 發光二極體 通訊用長波長(1.30µm/1.55µm) 通訊用短波長(0.85µm) 顯示用可見光波長(400-700 nm) 半導體雷射 長波長帶(1.55µm/1.3µm) 短波長帶(0.85µm) 資訊用短波長(460,650,670 nm)

  15. 光電產品－元件類 高功率發光二極體

  16. 光電產品－元件類

  17. 光子晶體 (Photonic Crystal) 晶體(如半導體)中的電子由於受到晶格的週期性位勢(periodic potential)散射，部份波段會因破壞性 干涉而形成能隙(energy gap)，導致電子的色散關係(dispersion relation)呈帶狀分佈，此即眾所周知的電子能帶結構 (electronic band structures)。 於光子系統中：在介電係數呈週期性排列的三維介電材料中，電磁波經介電函數散射後，某些波段的電磁波強度會因破 壞性干涉而呈指數衰減，無法在系統內傳遞，相當於在頻譜上形成能隙，於是色散關係也具有帶狀結構，此即所謂的光子能 帶結構(photonic band structures)。具有光子能帶結構的介電物質，就稱為光能隙系統(photonic band-gap system， 簡稱PBG系統)，或簡稱光子晶體(photonic crystals)。

  18. 光纖傳輸方面 光子晶體的應用 低損耗、無訊號延遲 可傳輸高功率雷射 大角度傳輸流失率低

  21. 德國福來堡(太陽能城市)的太陽能建築

  22. 燃料電池(Fuel cell)

  23. 燃料電池車商品化 指日可待 Tucson燃料電池車已經可在攝氏零下20度環境順利發動及行駛，同時也擁有長達300公里的續航力。 現代車廠利用運動休旅車Tucson所研製出的FCEV燃料電池車，已進入道路測試階段。 http://news.chinatimes.com/Chinatimes/ExteriorContent/CarProfessional/car-content/0,3883,170103+05082521+2,00.html
