生質廢棄物衍生之生物炭複合離子液體 應用於污染物處理

為了解決dyson vacuum的問題，作者吳兆禾 這樣論述：

本研究主要利用生質廢棄物衍生之生物炭複合離子液體應用於污染物處理。經由熱解廢棄菱角殼獲得生物炭(WCSB)作為吸附劑，同時為提高對金屬離子之吸附力，利用離子液體(1-Butyl-3-methylimidazolium hexafluorophosphate, [C4mim][PF6])進行改質WCSB， WCSB/[C4mim][PF6]重量比值為1、3、5、7並稱之為WI1、WI3、WI5、WI7，各別吸附pH4溶液中之Cr(VI)及Cu(II)，可見Cr(VI)吸附量提高，透過FTIR、XPS分析[C4mim][PF6]/WCSB吸附之機制，可觀察到Cu(II)會與WCSB上的C–O、C

-OH、COO-H作用形成鍵結或形成氧化物，吸附後WI7之pH由9.93降至8.53，使Cu(OH)2的含量增加，故Cu(II)吸附量提高，而Cr(VI)則是和WCSB的C-O及C-OH作用還原為Cr(III)，此外，由於吸附後WI1和WI3之pH分別由7.9降至4.26和4.57，Cr(VI)在酸性環境為HCrO4-的型態有利於吸附，因為隨著離子液體的加入，[C4mim][PF6]上的N+對Cr(VI)具有靜電吸引，促進Cr(VI)與WCSB反應還原成Cr(III)，而Cr(VI)在鹼性環境下為CrO42-，更有利於吸附在WI7。在應用於光觸媒的研究上使用經由熱解花生殼製成之花生殼炭(PSB

)，再將PSB使用Hummers法合成為花生殼氧化石墨烯(PSGO)，以溶劑熱法將Ti(Obu)4、PSGO以及[C4mim]Cl複合為光觸媒(PSGO-Cl-Ti)，利用UV-Vis DRS可以發現PSGO-Cl-Ti的能隙縮小及吸收邊波長增加，此外，XPS顯示Ti-O-C結構亦增加。比較PSGO-Cl-Ti和Ti-pure (未複合PSGO及[C4mim]Cl)的光觸媒對甲基橙降解速率以PSGO-Cl-Ti之降解速率較高，因在PSGO-Cl-Ti生成Ti-O-C的生成使TiO2生成之光電子快速轉移至PSGO，同時TiO2生成之電洞注入[C4mim]Cl的最高占據分子軌域，延長電子-電洞重組

時間，使光催化效果有所提升。在吸收太陽光降解之研究上，使用以PSGO、CuO、[C4mim][BF4]與TiO2進行複合之光觸媒(PSGO-CuO-BF4-Ti)並顯示其能提升降解速率，因此以反應曲面法(RSM)之Box-Behnken設計實驗並分析，顯示複合物PSGO、CuO、[C4mim][BF4]影響權重比為82.46%、7.30%、10.23%，最佳複合比例為1 g的TiO2複合PSGO為0.193 g、CuO為0.0027 g、[C4mim][BF4]為0.3626 mol，並以最佳條件複合光觸媒(PSGO-CuO-BF4-Ti (best)，PSGO-CuO-BF4-T (best

)之能隙為2.11 eV，並且在進行甲基橙降解實驗中顯示實驗結果與RSM預測結果相符。O 1s XPS可以發現PSGO 上的C-O、C=O與TiO2表面上的自由電子鍵結形成 Ti-O-C結構以及[C4mim][BF4]的複合促使TiO2產生缺陷結構，使能隙略微降低，此外Ti 2p XPS顯示因CuO的複合，使Ti 2p之結合能下降，因Cu離子進入TiO2晶格，形成氧空位導致電子電荷密度提高，並且Cu可作為電子受體抑制電子電洞對重組，因此PSGO-CuO-BF4-Ti (best)因複合PSGO、CuO及[C4mim][BF4]使光催化效果進一步的提升。

Dream Weaver

為了解決dyson vacuum的問題，作者Williams, Su 這樣論述：

Vampires sparkled through the spotlight. Then, the zombies shambled through. Now, it's time for a new paranormal. DREAM WEAVER. A beautiful, atmospheric story that is dark science fiction meets young adult. Nickolas Benedetti is a Dream Weaver; an ancient, arcane and almost immortal race with the po

wer to command memories and dreams. Nick plunges heart-first into tragedy-torn Emari Sweet's dark and nebulous life to save her from haunting night terrors...and finds his heart irretrievably entangled with hers. Nick saves Emari from her darkness, but can he save her from the real, living, breathin

g nightmares that have followed him to her doorstep? Dream Weaver has been called "well written. A powerful read, atmospheric and dark." Su Williams' "style packs a punch...imagery is original and precise." REVIEWS Reviewed by Anne Boling for Readers' Favorite If I could only use one word to describ

e Dream Weaver by Su Williams it would be SUPERB. Luckily, I get to use more than one. Dream Weaver is an unusual tale, part fantasy, part paranormal, part romance, part horror and part supernatural. When you roll all those genres into one you have a book you can't put down. I started reading this b

ook yesterday afternoon and finished it around 3 this morning. I'm usually a very fast reader but I found I wanted to read slowly to savor the exquisite moments of pleasure this book offers. Dream Weaver is Su Williams' first novel. I certainly hope it is not her last. Dream Weaver could easily be e

xpanded into a whole series of books. The ending is a bit of a cliffhanger, leading me to believe she has more books in mind. I've always been curious about the Nephilim and love the idea of an expanded series of books on the topic, even if it is all fiction. This is a series fans of fantasy will no

t want to miss. The Eyes Have It This book is a clear case of "the eyes have it". You are drawn in immediately by the cover image. The imagery of a young girl asleep with the mesmerizing eyes overlooking her bed instantly gets your brain working on numerous levels. Are the eyes evil or they good? T

hese are just a few of the things that go through your head. It is always good if you can get someone's brain working before they even open the cover of the book. Once Su gets you inside the book, the fun really begins. The young sleeping girl becomes a tragic figure in her own life. So many horribl

e things happen to her in such a short amount of time she begins to think she cannot make it and looks to over means of comfort. The dream weaver, Nick is painfully aware of her plight and does all he can to end her pain. I don't want to ruin the story line, but as the story continues Nick and Emari

must face many decisions that will affect both of them together an individually. There are many twists in this story that no one really sees coming until you are in the middle of them. The story is exciting and suspenseful. Ms. Williams does an excellent job of handling some very delicate social is

sues that affect many of our young adults today. Her characters are developed well and the plight of the young Emari is most believable. Emari suffers from an actual condition well known among our young people and Ms. Williams works hard in her story line to let those young people know that there is

more to life than pain. She gives them a choice and a way out of their misery. Not only is this a fabulous fantasy read, it is a social commentary that lends help and support to a number of afflicted young people. Ms. Williams has written the story with the compassion of one that understands and kn

ows the pain that they feel. The helpful message is there and clearly stated for those that need it, for the rest of us, it is just a mesmerizing story full of beautiful imagery and fabulous characters. The book is well worth the price in entertainment alone. Kandy Kay Scaramuzzo I confess...I’m a

bit of a dork, with a quirky and sometimes dark personality, though not as dark as some. I love nature and the outdoors, and love to photograph them. Pictures of normal things taken from abnormal angles are one of my favorites. One of my photos has been published in the political humor book Red Dog

/Blue Dog by Chuck Sambuchino. Legally, my name is Susan Barton, but I write under the pen name Su Williams (my maiden name). I am a 48 year old mother of 4, Sarah, Josiah, Jack and Aundraic. I’m married to Ben and we have 2 cats, a garder snake, a crested gecko named Reid (like in Criminal Minds) a

nd a beagle, Dyson (yes like the vacuum) who is my favorite teddy puppy. I was born in Little Rock, AK. My daddy was military and my parents finally decided that Spokane, WA was the place for us and this is where I’ve lived since I was about 10. I always wrote special poems for family birthdays, and

began to write short stories in Jr. High. Many years later after a self-esteem building program of hypnosis, and reading Twilight, I was inspired. I said, ＂I could do that.＂ So I did. Dream Weaver has been 4 years in the making, as I’ve learned the ins and outs of the literary process. That is an o

ngoing endeavor. Who knew how much research went into writing a novel? Not me. I’m learning everything from SEO (search engine optimization) and promotion to drafting a great query letter and how to do it yourself on sites like Create Space. My goal is to get Dream Weaver into the hands of people wh

o will love Emari, Nick, Eddyson, Sabre, Ivy and Jesse as much as I do. Dream Weaver is the first of 3 planned novels. The second is called Rock Star in which Emari lives the life of a rock star and discovers that Nick is really not who he claims to be. Finally, in Private Eye, Emari will team up wi

th Officer Molly to solve some of Spokane’s open and cold cases and will unveil the truth behind the crash that killed Emari’s parents.

以第一原理與量子傳輸理論來計算在汲源極與閘極電壓下之二硫化鉬/金屬側接觸

為了解決dyson vacuum的問題，作者洪崇銘 這樣論述：

以消除「過渡金屬硫族化物(TMD)」與「金屬」頂接觸的凡德瓦間隙為出發點，我們採用側接觸幾何結構來促成介面形成鍵結。本研究以第一原理及量子傳輸理論來計算「單層二硫化鉬(MoS2)」與「金屬」側接觸結構。透過計算不同金屬接觸，我們看到蕭特基位障(SBH)受金屬功函數高低的影響，並比較側接觸與頂接觸兩者能帶對齊的差異。此外我們也以人工增加(減少)電子的方式，分別計算電極與三奈米N型、P型通道相接的整體電阻，以便初步篩選較適合作為N型與P型二維電晶體的電極金屬。我們模擬鋁/二硫化鉬、鉑/二硫化鉬側接觸的閘極電壓效應，前者為N型而後者為P型，並利用傳輸線方法(TLM)擷取其接觸電阻分別為122 Ω·

μm、174 Ω·μm，兩者由閘極造成的通道電位分別為0.83V、0.63V。為了要讓閘極造成的通道電位對上述兩種金屬接觸是一固定變因，我們揣摩兩者「閘極通道電位」皆為0.83V時，將簡化近似過的古典傳輸波茲曼理論，用在我們所計算出的能帶圖，可推論出鉑/二硫化鉬能夠達到比鋁/二硫化鉬更低的接觸電阻(約為58 Ω·μm)，也就是兩者比實驗上最低接觸電阻123 Ω·μm的鉍/二硫化鉬頂接觸都還低。而調變閘極電壓時所得Al/MoS2、Pt/MoS2之ID-VG特性曲線，可從中計算出兩者的次臨界擺幅值皆接近目前廣泛使用的矽材料的理論極限60 mV/decade，因此選擇鋁、鉑金屬與二硫化鉬形成側接觸，
