擬有序中孔高熵及有序中孔擬高熵 材料之開發

為了解決In outer space的問題，作者陳鵬仁 這樣論述：

高熵材料因其性質多元而在材料應用中具有極大的潛力，截至目前為止，尚未發現有文獻製備有序中孔高熵氧化物，本研究致力於開發有序中孔高熵氧化物之製程，分別透過軟模板法與硬模板法合成高熵中孔氧化物。其中，軟模板法源自SBA-15之製程，並探討氧化矽源、鹽酸、鹼之種類及其滴定方法對產物的影響；硬模板法則以CMK-3為模板合成有序中孔高熵氧化物，並探討前驅物/硬模板比例、前驅物/氨水比例、溶劑種類、鹼的種類、不同手法(尿素內調法、氨水氣化法、氫氧化鈉潮解法、尿素水解氣化法)進行之中和反應、模板表面改質，以及鍛燒溫度對孔洞結構的影響。在廣泛地嘗試各種極端條件後，雖然仍無法合成理想的有序孔洞高熵氧化物，原因

可能是由於高熵氧化物本身以及中孔材料之骨架本身皆具備大量的晶格應變，導致其結構容易崩塌。具體來講，本研究以軟模板法成功合成具有高比表面積的有序中孔擬高熵氧化物(比表面積：369 m2/g；平均孔徑：7.7 nm)；而透過硬模板法中也成功合成了擬有序中孔高熵氧化物(比表面積：90 m2/g；平均孔徑：~10.0 nm)。在光催化還原CO2的應用中發現96小時候可以達到687.07μmol∙CO/g以及88.65μmol∙CH4/g； 水解製氫24小時可達2.16 % g-cat-1。

Space Race 2.0: Spacex, Blue Origin, Virgin Orbit, Nasa, and the Privatization of the Final Frontier

為了解決In outer space的問題，作者Bergan, Brad 這樣論述：

Space Race 2.0 is the only authoritative photographic history of the efforts of private companies--often alongside NASA--to accelerate humankind’s exploration and understanding of the final frontier. The private space sector is growing tremendously. The industry’s consensus leader, SpaceX, headed

by outspoken billionaire Elon Musk, is today worth an estimated ＄74 billion. And SpaceX and its chief competitors, Blue Origin and Virgin Galactic, are taking on more roles--flying cargo, supplies, and astronauts to outer space. Space Race 2.0 tells their story with expertly written text by science

journalist Brad Bergan and stunning photography of the spacecraft, key players, and facilities in California, Texas, and Florida. In the 1950s and ’60s, the first Space Race pitted two political ideologies against one another: either Communism or Capitalism would prove superior. Ultimately, the US

landed on the moon, the race’s crowning achievement. Now, more than a half-century later, the Space Race has pivoted from a contest between ideological rivals to private aerospace firms competing for contracts. Today, rather than symbolic goals motivated by patriotism, the defining success of a la

unch system extends beyond engineering and science to image and ROI. Founded in 2002, SpaceX’s trajectory was determined by Musk’s realization that he could achieve higher profits by vertically integrating--manufacturing his own rockets and spacecraft--rather than relying on third parties. The decis

ion was prescient, resulting in a state-of-the-art headquarters in Hawthorne, California, and a series of stunning achievements. Space Race 2.0 follows the development of commercial space exploration to the present. While tentative first steps in private ventures are covered, such as those by Space

Services Inc. and Orbital Science in the 1980s and ’90s, the focus is on today’s major players: SpaceX, Blue Origin (headed by Amazon founder Jeff Bezos), and Virgin Galactic (founded by Richard Branson). While examining the hardware, Bergan also explores such considerations as the importance of des

ign-forward equipment and the endgame: what ultimately is ＂in it＂ for firms at the forefront? Natural resources? NASA and ESA contracts? Commercial travel? Communications? And what legal boundaries, if any, restrain corporate interests in space? Space Race 2.0 is the ultimate visual look at this rel

atively young industry, looking back at recent remarkable decades--and ahead to what the future might bring.

雙級同軸離心式抽水泵浦之性能改善與模擬分析

為了解決In outer space的問題，作者趙崇臻 這樣論述：

本研究目標為家用雙級同軸離心式泵浦之性能改善，其特點為採用兩級葉輪固定在同軸，故只需要一個馬達並可減少安裝所需空間，但這也使兩級動葉輪間的流道變得十分複雜，離開第一級葉輪的流體必須在極狹窄空間轉180度，再由外圍以徑向往中心進入第二級葉輪入口 ; 另外離開第二級動葉輪的流體也有著相似的情形，必須在短距離轉向才能由泵出口排出，上述問題成為提升泵浦性能及效率時的巨大挑戰。本研究選用CFD軟體Fluent作為分析工具，對同軸離心泵浦做流場聲場的數值模擬，由流場可視化了解內部流場，進一步提出相對應之改善方案，主要的改善對象分為葉輪及流道 ; 首先對靜葉輪和動葉輪進行參數優化，其中靜葉輪考量的參數有入

口角度、葉片擺設方向及葉數，而動葉輪包括葉片角度和葉片數。數值參數分析結果顯示，動葉輪在第一級11葉、第二級8葉、入口角60∘和出口角50∘的參數組合下，其流量在低揚程(5.56m)時增加7.9% (由138到148.9 LPM)，於高揚程(24m)時上升67% (由34.8到58.1 LPM) ; 至於效率部份，則在低揚程維持在18.1%，另外高揚程則有顯著提升從45.0%提升到52.9%。接著進行各連接流道部份之改良，包括進口與出口銜接流道的流線化，結果顯示成功地去除流場混亂與局部高壓區，也提升高揚程之流量和效率。最後搭配優化葉輪和改良流道的新泵浦設計，其數值計算結果顯示，於24m的高揚程

操作情形下，其流量可增加到72.8 LPM，為原始設計的2倍多，靜壓效率也再增加4%到56.9%，同時所產生的聲壓分貝值則維持不變。綜合歸納而言，本數值研究成功建立一套系統分析模式，可用來改良泵浦的靜葉輪、動葉輪及流道，且此方法對於雙級同軸離心式泵浦在高揚程時有明顯的效果。
