Biodiesel as an Alternative Fuel: Value Chain, Performance, Feasibility and Sustainability

為了解決Promising的問題，作者Kumar, Dipesh,Singh, Bhaskar 這樣論述：

Biodiesel as an Alternative Fuel: Value Chain, Performance, Feasibility and Sustainability provides a fundamental understanding on the state-of-the-art processes involved in the production of biodiesel. The book offers a holistic analysis of mass scale biodiesel production in terms of techno-econ

omic viability and sustainability challenges in the 21st century. It covers the entire biodiesel value chain, from feedstock production and conversion processes, to post-production refining and fuel quality assessment. Besides conventional approaches, recent technologies holding promising opportunit

ies are discussed in-depth. The book’s authors analyze and address major industry and environmental concerns in their discussion of lifecycle assessment and techno-economic assessment. By exploring the fundamental concepts, latest developments and sustainability aspects, the book offers a complete u

nderstanding of the feasibility and sustainability of biodiesel. Researchers and PhD students coming into the field will be able to use this reference to acquire a holistic perspective of the subject. In addition, more experienced researchers and industry practitioners will benefit from the book’s t

echno-economic approach that will help readers make better-informed decisions when developing and deploying biodiesel-based technologies.

用於染料敏化電池的無金屬有機染料之結構設計

為了解決Promising的問題，作者吳杰畢 這樣論述：

摘要第三代光伏的染料敏化太陽能電池 (DSSC)的興起，造成在過去的三十年中被廣泛地探索，因為它們具有的獨特特性，例如成本低、製造工藝簡單、輕巧、柔韌性好、對環境友善，並且在弱光條件下，仍具備突破性的高效率。儘管， DSSCs 依然有許多須待優化的部分，但藉由光捕獲染料光敏劑的分子結構設計，在優化 DSSCs 性能參數方面扮演關鍵的作用。因此，尋找符合DSSC需求的光敏染料，是該研究領域的關鍵研究方向之一。本論文的最終目標是在標準日照和弱光條件下，尋找高效穩定的有機光敏染料。這項工作是藉由無金屬有機光敏劑的系統結構工程來完成的，針對分子結構設計與光電特性的關聯及DSSC的效能表現。在本論文中

，我們已經合成了各種新型光敏染料，並對這些無金屬有機光敏染料進行了逐步的結構修飾，例如在單個敏化染料中引入一對輔助受體，在 D-A-π-A 框架中引入龐大的芴基實體，並增加共平面性以及延伸喹喔啉染料主要框架的共軛。通過使用各種光譜、電化學和理論計算來研究這些光敏染料的結構性質，以符合它們在DSSC主要特徵之應用前景。最後，在本論文中，我們展示了一組無金屬有機光敏劑，其元件效率高，在標準太陽照射下的效率超過 9%，在 6000 lux 的弱光照下，效率超過 30%，這將是一個具有未來發展潛力的結構設計，可以在沒有共吸附劑的情況下實現高效率。

The 30 Day Mental Challenge

為了解決Promising的問題，作者Horowitz, Mitch 這樣論述：

What Would You Give to Lead a Bold, Satisfying, and Successful Life?Author Mitch Horowitz (＂solid gold＂--David Lynch) asks you to give one thing: your mental focus for just 30 days. In The 30-Day Mental Challenge, Mitch guides you through one simple exercise--so simple, in fact, that you may not

believe it can change anything. But, like thousands who have tried, you will be surprised. You are to direct your thoughts for 30 days toward what is productive, forwarding, and promising--and to believe that every reasonable ambition is within your reach. That’s it. Simple as it sounds, however, t

his exercise places you in front of tremendous and unforeseen challenges. Hence, Mitch guides you--with realism, bluntness, and authentic ideals--through each day to help you stay on track, contend with pitfalls (which are many), and witness concrete results.Effort is all it takes. Will you try? Man

y have said yes only to drop off. Many others have stayed on. Their testimonies appear in the book, including: ＂I always dismissed the ’positive thought’ movement as something somehow beneath me, preferring complicated and arduous meditation and nuanced esoteric rituals for my own self-improvement j

ourney...These meditations have been a lifesaver during a very challenging time. No lie.＂ ＂This has been transformative beyond expectation.＂ ＂The 30-day challenge has helped me overcome so many obstacles and I feel so grateful. Magick is real and man, it is such a beautiful, positive thing!＂ Your ti

me is now. Join The 30-Day Mental Challenge.

高功率可變出光角光子晶體面射型雷射之特性研究

為了解決Promising的問題，作者陳立人 這樣論述：

本論文旨在研究高功率可變出光角之光子晶體面射型雷射的設計，製作及其光電特性。光子晶體面射型雷射因具備大功率操作及發散角小等特性，近年來頗受矚目，被視為是3D感測，光達，和雷射加工等應用領域的理想光源；研究首先藉由數值模擬計算來探討磊晶結構及光子晶體結構對於雷射閾值及出光效率的影響，進而得到較佳的磊晶結構同時配合不同的光子晶體結構來進行實驗驗證，實驗與模擬的結果均顯示雷射的斜率效率隨著光子晶體結構的對稱性下降而大幅上升，實驗並針對P面向上的結構進行優化，使得光輸出功率進一步提升，同時我們也針對大功率單模操作進行探討。另一方面我們也針對改變鐳射出光角度的機制進行研究以實現光束掃描的新奇雷射結構。

先後評估了主動式的光學相位陣列，主動式光柵結構，雙調變式光子晶體結構以及超穎結構等方式，考量結構整合的便利性及發光效率等因素，我們採用雷射整合表面超穎結構的方式進行設計，超穎結構的設計使用了奈米結構陣列及反向設計兩種方式，在砷化鎵基板上實驗的結果顯示此結構可將雷射光偏轉至設計的角度並且抑制原本垂直方向上的雷射光，此超穎結構結合光子晶體面射型雷射將得到高效率且緊湊的光束偏轉雷射，進一步製作成不同出光角度的陣列並單獨控制即可實現掃描功能，預期此雷射結構在上述的應用領域有著相當大的潛力。
