Graetzel is also a leader in the field of fuel generation by sunlight, which is a key technology to provide future renewable energy sources that can be

stored. His group uses tandems of two photosystems to split water into hydrogen and oxygen and reduce carbon dioxide by visible light. His 1645 publications have received some 284,000 citations and his h-index is 243. Anyi Mei got his PHD in Huazhong University of Science and Technology in 2018. A

fter that, he continues his research in the university and becomes an associate professor in Wuhan National Laboratory for Optoelectronics in Huazhong University of Science and Technology. His research focuses on printed mesoscopic solar cell materials and devices. He has published more than 60 peer

-reviewed articles with H-index 27. Dr. Yue Hu is currently associate professor of Huazhong University of Science and Technology. Dr. Hu has carried out a series of pioneering work in the fields of dye-sensitized solar cells and perovskite solar cells. From the perspectives of molecular design, mat

erial synthesis, interface modification, device optimization and mechanism analysis, Dr. Hu Yue has developed a series of new low-cost light absorbing materials focusing on the photoelectric conversion efficiency, stability and cost of mesoscopic solar cells. She has participated in many scientific

research projects of the Royal Society of chemistry and the National Natural Science Foundation of China. She has published more than 80 research articles in international journals including Science, Advanced Materials, and Advanced Energy Materials etc. with H-index 25.

運動訓練與停止訓練對中老年人骨骼肌氧合能力與身體功能表現之影響

為了解決Hydrogen energy的問題，作者杨永 這樣論述：

運動是一種改善中老年人骨骼肌氧合能力、提高肌肉力量並最終影響整體身體功能表現的有效方式。然而，較少的研究評估不同運動類型之間訓練效益的差異。此外，由於中老年人生病、外出旅行與照顧兒童等原因，迫使運動鍛煉的中斷。如何合理安排運動訓練的週期、強度與停訓週期，以促使中老年人在未來再訓練快速恢復以往訓練效益，目前亦尚不清楚。本文以三個研究建構而成。研究I：不同運動訓練模式對中老年人的骨骼肌氧合能力、肌力與身體功能表現的影響。以此探討50歲及以上中老年人進行每週2次為期8週的爆發力、阻力訓練以及心肺訓練在改善中老年人肌肉組織氧合能力、與肌肉力量身體功能效益的差異。我們的研究結果表明：爆發力組在改善下肢

肌力、最大爆發力與肌肉品質方面表現出較佳的效果。心肺組提高了30s坐站測試成績並減少了肌肉耗氧量，從而改善了中老年人在30s坐站測試期間的運動經濟性。年紀較高的肌力組則對於改善平衡能力更加有效。此外，三組運動形式均有效改善了中老年人人敏捷性。研究 Ⅱ：停止訓練對運動訓練後中老年人肌力與身體功能表現的影響：系統性回顧與meta分析。本研究欲探討停止訓練對運動訓練後中老年人肌力與身體功能表現訓練效益維持的影響。我們的研究結果表明：訓練期大於停止運動訓練期是肌力維持的重要因素。若訓練期

Handbook on Solar Thermal Technologies: Concentrating Solar Power and Fuels (in 3 Volumes)

為了解決Hydrogen energy的問題，作者 這樣論述：

The three-volume handbook showcases the state of the art in the use of concentrated sunlight to produce electricity, industrial process heat, renewable fuels, including hydrogen and low-carbon synthesis gas, and valuable chemical commodities. The handbook illustrates the value and diversity of ap

三相電磁噴流之研究

為了解決Hydrogen energy的問題，作者鄭力瑋 這樣論述：

摘要電磁噴流是一種運用磁流體力學(Magnetohydrodynamics, MHD)之概念，當給予電極板電能與固定磁場時，便可產生勞倫茲力，藉此推動導電流體。其優點在於致動原理簡易，且不需要依靠複雜的機械結構，便可實現推送之效果。常見的應用在微尺度之微動幫浦與大型船體無槳式推進器上，以往許多研究都著重在電場與磁場之設計與幾何構型的最佳化，而本研究透過實驗探討在電磁噴流中，電極板附帶產生電化學反應而生成氣泡所構成之多相噴流場。並藉由染劑與氣泡之方式發展一流場可視化之方法。本研究透過計算染劑之汙染面積並與數值模擬結果進行比較，發現在低電流時之預測流量結果較為相近。並定義一無因次參數為勞倫茲力雷

諾數(Re_L)，用以描述電磁噴流之流場型態，實驗結果透過定性觀察當勞倫茲力雷諾數(Re_L)大於1600時，噴流型態會發展成紊流的型式。透過無因次分析結果也顯示其噴流擴散角(θ)與氣泡佔比(Ag)有隨Re_L數增加而有上升之趨勢，且在Re_L數大於1600後，因流場型態轉變，擴散角與氣泡佔比也有明顯上升之現象。在最後討論使用鋁電極板對於電磁噴流之影響。
