X-Nuclei Magnetic Resonance Imaging

為了解決Fluorine used for的問題,作者 這樣論述:

Standard magnetic resonance imaging (MRI) is a prominent clinical imaging modality used to diagnose and study diseases in vivo. It is principally based on the detection of the nuclei of hydrogen atoms (the proton; symbol 1H) in water molecules in tissues. X-nuclei MRI (also called non-proton MRI)

is based on the detection of the nuclei of other atoms (X-nuclei) in the body, such as sodium (23Na), phosphorus (31P), chlorine (35Cl), potassium (39K), deuterium (2H), oxygen (17O), lithium (7Li), and fluorine (19F) using modified software and hardware. X-nuclei MRI can provide fundamental, new m

etabolic information related to cellular energetic metabolism and ion homeostasis in tissues that cannot be assessed using standard hydrogen MRI.This book is an introduction to the techniques and biomedical applications of X-nuclei MRI. It describes the theoretical and experimental basis of X-nuclei

MRI, the limitations of this technique, and its potential biomedical applications for the diagnosis and prognosis of many disorders or for quantitative monitoring of therapies in a wide range of diseases. The book is divided into four parts. Part I includes a general description of X-nuclei nuclear

magnetic resonance physics and imaging. Part II deals with the MRI of endogenous nuclei such as 23Na, 31P, 35Cl, and 39K; Part III, the MRI of endogenous/exogenous nuclei such as 2H and 17O; and Part IV, the MRI of exogenous nuclei such as 7Li and 19F. The book is illustrated throughout with many r

epresentative figures and includes references and reading suggestions in each section. It is the first book to introduce X-nuclei MRI to researchers, clinicians, students, and general readers who are interested in the development of imaging methods for assessing new metabolic information in tissues

in vivo in order to diagnose diseases, improve prognosis, or measure the efficiency of therapies in a timely and quantitative manner. It is an ideal starting point for a clinical or scientific research project in non-proton MRI techniques.

異質元素摻雜還原氧化石墨烯電極於儲能裝置之應用研究

為了解決Fluorine used for的問題,作者古安銘 這樣論述:

儲能技術超級電容器的出現為儲能行業的發展提供了巨大的潛力和顯著的優勢。碳基材料,尤其是石墨烯,由於具有蜂窩狀晶格,在儲能應用中備受關注,因其非凡的導電導熱性、彈性、透明性和高比表面積而備受關注,使其成為最重要的儲能材料之一。石墨烯基超級電容器的高能量密度和優異的電/電化學性能的製造是開發大功率能源最緊迫的挑戰之一。在此,我們描述了生產石墨烯基儲能材料的兩種方法,並研究了所製備材料作為超級電容器裝置的電極材料的儲能性能。第一,我們開發了一種新穎、經濟且直接的方法來合成柔性和導電的 還原氧化石墨烯和還原氧化石墨烯/多壁奈米碳管複合薄膜。通過三電極系統,在一些強鹼水性電解質,如 氫氧化鉀、清氧化鋰

和氫氧化鈉中,研究加入多壁奈米碳管對還原氧化石墨烯/多壁奈米碳管複合薄膜電化學性能的影響。通過循環伏安法 (CV)、恆電流充放電 (GCD) 和電化學阻抗譜 (EIS) 探測薄膜的超級電容器行為。通過 X 射線衍射儀 (XRD)、拉曼光譜儀、表面積分析儀 (BET)、熱重分析 (TGA)、場發射掃描電子顯微鏡 (FESEM) 和穿透電子顯微鏡 (TEM) 對薄膜的結構和形態進行研究. 用 10 wt% 多壁奈米碳管(GP10C) 合成的還原氧化石墨烯/多壁奈米碳管薄膜表現出 200 Fg-1 的高比電容,15000 次循環測試後保持92%的比電容,小弛豫時間常數(~194 ms)和在2M氫氧化

鉀電解液中的高擴散係數 (7.8457×10−9 cm2s-1)。此外,以 GP10C 作為陽極和陰極,使用 2M氫氧化鉀作為電解質的對稱超級電容器鈕扣電容在電流密度為 0.1 Ag-1 時表現出 19.4 Whkg-1 的高能量密度和 439Wkg-1 的功率密度,以及良好的循環穩定性:在,0.3 Ag-1 下,10000 次循環後,保持85%的比電容。第二,我們合成了一種簡單、環保、具有成本效益的異質元素(氮、磷和氟)共摻雜氧化石墨烯(NPFG)。通過水熱功能化和冷凍乾燥方法將氧化石墨烯進行還原。此材料具有高比表面積和層次多孔結構。我們廣泛研究了不同元素摻雜對合成的還原氧化石墨烯的儲能性能

的影響。在相同條件下測量比電容,顯示出比第一種方法生產的材料更好的超級電容。以最佳量的五氟吡啶和植酸 (PA) 合成的氮、磷和氟共摻雜石墨烯 (NPFG-0.3) 表現出更佳的比電容(0.5 Ag-1 時為 319 Fg-1),具有良好的倍率性能、較短的弛豫時間常數 (τ = 28.4 ms) 和在 6M氫氧化鉀水性電解質中較高的電解陽離子擴散係數 (Dk+ = 8.8261×10-9 cm2 s–1)。在還原氧化石墨烯模型中提供氮、氟和磷原子替換的密度泛函理論 (DFT) 計算結果可以將能量值 (GT) 從 -673.79 eV 增加到 -643.26 eV,展示了原子級能量如何提高與電解質

的電化學反應。NPFG-0.3 相對於 NFG、PG 和純 還原氧化石墨烯的較佳性能主要歸因於電子/離子傳輸現象的平衡良好的快速動力學過程。我們設計的對稱鈕扣超級電容器裝置使用 NPFG-0.3 作為陽極和陰極,在 1M 硫酸鈉水性電解質中的功率密度為 716 Wkg-1 的功率密度時表現出 38 Whkg-1 的高能量密度和在 6M氫氧化鉀水性電解質中,24 Whkg-1 的能量密度下有499 Wkg-1的功率密度。簡便的合成方法和理想的電化學結果表明,合成的 NPFG-0.3 材料在未來超級電容器應用中具有很高的潛力。

應用於酸性稀釋溶液導電度量測的IDT感測系統

為了解決Fluorine used for的問題,作者蕭宇良 這樣論述:

本研究為將指叉電極感測器用於量測酸性稀釋溶液的導電度,並開發了一個基於ESP32微控制器的感測系統,其感測系統包含系統電源、波型產生器電路、相位振幅檢測電路、恆流源電路,使用1.6V、1KHz的正弦波輸入至IDT感測器中,將振幅與相位電壓值通過ESP32運算出當前振幅與相位,恆流源電路提供4-20mA輸出應用於工業感測器的標準電流值,IDT感測器設計後將圖案轉印至PCB板上,之後將其封裝並且使用電鍍製程,將鎳與金鍍於銅金屬上便完成IDT感測器製作,也通過PCB廠商使用ENIG-RoHS製程將設計完成的IDT感測器大量製造。根據實驗的結果,使用不同的水(DI、RO、自來水)進行稀釋BOE和HC

l,當BOE或HCl與水稀釋比例越多,其振幅將由小變大,並呈現指數關係,指出當濃度越稀時量測中的溶液導電度就越差,在輸入訊號與感測器上訊號的相位差變化大約從-65o變化至-10o,並利用振幅與相位值計算出阻抗變化。通過變化頻率實驗,其頻率越高時感測器獲得的振幅會越小,而當感測器指數越多時其阻抗將會越低。最後將感測器置於含氟的製程廢水中量測,顯示出製作的感測系統可以辨識出純水與通入NF3氣體的溶液差異。
