為了解決Constant frequency的問題，作者Burke, Jeremy 這樣論述：

This is the story of a little boy in being terrorized by bullies every day. It started on the bus with verbal taunts by bullies to all kids. Everyday they systematically made their way around teasing everyone. When it was my turn for ridicule, I tried to ignore them and hoped they would go away. Eve

ntually the bullies pushed further and more aggressive in their attacks to get a reaction. As they increased pressure, I would retreat further into a dark hole of emptiness to get away. This drove them more and more to hurt me. Eventually I caved and started to cry. Once the tears started coming I c

ouldn't do anything to stop it. I was suffering and the pain was deep in my soul. It was a huge victory for the bullies to get a victim to cry.Later, the attacks became more frequent and more physical. They would slap my head, flick my ears, punch & poke me. They would pull my shoes off and even thr

ow them out the bus window. And the bullying made it's way off the bus and into school, the schoolyard and even out in public places. I couldn't get away. No matter where I went there was a chance those boys would find me. Whether it was in the woods behind our neighborhood, the mall arcade, grocery

store or sledding hill behind our church. They were everywhere. Constantly hunting and tormenting me. At least I assumed I was their mission in life. I lived in constant fear, always looking over my shoulder. Always worried they were coming for me. As a 9 old boy, no one should have to live life be

lieving they're being hunted. The level of PTSD I was experiencing is far too much for anyone of that age to deal with. It led to bedwetting, nightmares and a severe lack of focus in school. I was always a bad student. Nothing made sense to me and I couldn't figure out why I was failing. Teachers sa

id I should be held back a grade, some labeled me ignorant or learning disabled and others made fun of me in front of my peers. Needless to say I hated school and life. My book details the plight of bullying that goes on every day in schools all over the country. You'll hear details about how I was

systematically broken down to the darkest lows where a soul could go. I discuss failures of the system along the way as I was being bullied. The Bus Driver that saw it all, the principal that heard from my mother about how I looked getting off the bus being beaten to finally the bully's parents deny

ing any wrong doing of their son. Many adults knew what was going on but none did much about it. I conclude the book with details on how to fix the epidemic. It won't be easy, we'll never wipe it out completely. But we can take a stand against bullying and have to do it together. We have to start no

w. The first step begins with parents. Parents need to get real selfish about the welfare of their children and demand accountability from the schools. Schools need to put aside politics and get real about bullying. Kids are not a statistic that should affect budgeting or ratings. They're kids. Teac

hers and school administrators have custody of our children for about 1/3 of the day and bear responsibility to ensure their safety and their upbringing. Work with the parents and get solutions that work for all in these matters. Lastly we need to work with children and teach them self esteem and pe

rsonal accountability. For those that are bullied, we need to show them that they can protect themselves. They have that right and they should always fight against aggression. For those that bully others, we need to pull them aside with parents and school administrators and figure out why they are c

onducting themselves in that manner. It may be for a multitude of reasons. But we have to dig deep and know that we can help even those that torment others. Our mission in life should be to ensure the next generations have a better opportunity for growth and success. Bullies come at us from all walk

s of life and from all age brackets. We need to resist and put and end to it. Jeremy M. Burke has recently published a book detailing the story of his childhood when he was bullied on almost a daily frequency beginning when he was 9 years old. The story begins in fourth grade while on the bus. Som

e older kids spent their time on the bus ride and to and from school tormenting all the younger kids. When it was Jeremy’s turn in the gauntlet he was unprepared to face the level of terror these older boys inflicted on everyone. Throughout the story you’ll hear how he tried to escape further into a

subconscious dark place to run away from his fears. As the weeks and months went on it escalated and went from verbal tormenting to physical abuse. These years of terror turned him into a lost kid who somehow made it through the turmoil of adolescence without killing himself. He lived every day in

fear and these fears expanded and followed him every where he went. Jeremy was constantly on alert and always looking over his shoulder for when the bullies would come for him again. His story is a wake up call to the parents of the world to get involved in their children’s lives, learn what’s going

on and don’t take lip service from anyone that says they’ll ＂take care of it＂. And this is also for the teachers, administrators and any other adult at schools to put aside the political correctness and stop protecting those that are tormenting others. If you’re going to take a stand then take that

stand! Don’t just say you are. Jeremy’s parents decided when he was in eighth grade to take him out of the public school system and enroll him in the Jesuit run Canisius High School in Buffalo. After Canisius, Jeremy graduated from another Jesuit institution, St. Joseph’s University in Philadelphia

. Upon graduation, Jeremy was commissioned as an officer in the US Army and served in the National Guard and Army Reserve including one tour in Iraq as part of Operation Iraqi Freedom. He is married to his wife, Thea and father to two twin girls, Erin & Fiona, currently attending high school as Soph

omores. Jeremy has been a small business owner and entrepreneur. Currently he is the head brewer at Steel City Coffee House & Brewery. Additionally he has recently founded a new business, Follow Me Leadership, which focuses on speaking and mentoring kids and adults to combat bullying in life and enc

ourage others to Stand Up, Fight Back and live with a Follow Me mentality.

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Constant frequency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。
