A Considerable Achievement: The Tactical Development of the 56th (London) Division on the Western Front, 1916-1918

為了解決second form of be的問題，作者Brosnan, Matt 這樣論述：

Nearly a century on, the operational performance of the British Expeditionary Force (BEF) on the Western Front during the First World War is still a hotly debated subject. The dominant perception is one of a conflict characterized by mud, trenches and futility, presided over by incompetent comman

ders. But over the last thirty years a different view has emerged and gained increasing prominence. Many historians have argued that the BEF deserves more credit for the wartime learning curve it underwent in evolving from a small professional force into a mass citizen army, which helped it to end t

he war victorious. The BEF has become the subject of even more detailed research, as historians have sought to investigate all aspects of its operational practice. This book enters into this debate by taking a detailed look at a single infantry division, one of the BEF's vital constituent parts. It

focuses on the 56th (London) Division, a first-line Territorial division that served continuously on the Western Front between February 1916 and November 1918. By focusing on and comparing three key battles in the Division's service - the Battle of Gommecourt on 1 July 1916, the Battle of Arras on 9

April 1917 and the Battle of Albert on 23 August 1918 - this study provides detailed insight into 56th Division's tactical development. It suggests that by the last year of the war, 56th Division had developed sophisticated offensive tactics born out of years of hard-fought experience. This study u

tilizes a range of archival sources, including the official documents of war diaries, operational orders and battle reports. But it also references the private papers of the officers and men who served in 56th Division, gaining the insight of individuals who witnessed and took part in these events a

t first hand. The voices that emerge from these sources are a testament to the dedication of many of the men who served with the Division and who helped it to develop increasingly effective fighting methods, as was also the case with the BEF as a whole. The 56th (London) Division therefore deserves

to be remembered for its contribution to a painful, but ultimately victorious war effort. Matt Brosnan was educated at the University of Birmingham, where he studied History and English at undergraduate level and then Twentieth Century British History at postgraduate level. His postgraduate research

was on the tactical development of 56th Division on the Western Front, which has been extended to form the present study. Since 2006 he has worked at the Imperial War Museum in London, initially as a Curator in the Department of Art, which holds the largest collection of modern British art outside

the Tate. He curated displays on the Hall of Remembrance art scheme of the First World War and Neo-Romantic art of the Second World War period. He currently works as a Historian in the Research and Information Department, where he is researching forthcoming exhibitions on Frontline Medicine and also

for the centenary of the First World War. A Considerable Achievement is his first publication. He was born and lives in north London.

布里斯洛中間體自由基反應機制之理論研究

為了解決second form of be的問題，作者謝明修 這樣論述：

含氮雜環卡賓（N-heterocyclic carbene）催化之化學反應中，布里斯洛中間體（Breslow intermediate）扮演重要的催化角色。布里斯洛中間體能以親核基（nucleophile）或自由基（radical）之形式參與反應。本論文探討布里斯洛中間體之自由基特性及形成機制（mechanism），其自由基可從氫自由基轉移或直接氧化形成。安息香縮合反應（benzoin condensation）中，布里斯洛中間體將氫原子轉移至苯甲醛（benzaldehyde）以形成自由基，此自由基可結合形成安息香產物，或排除反應之副產物，使其重新進入催化反應。唯此路徑之反應能障高於傳統非自

由基路徑。此研究亦探討四種布里斯洛中間體之不同電子組態的位能面。其中烯醇鹽（enolate）形式能產生偶極束縛態（dipole-bound state），此為產生自由基之新路徑；拉電子基（electron-withdrawing group）以及立體障礙基（bulky groups）可穩定基態。另外，我們亦研究布里斯洛中間體之碎片化（fragmentation）與重組（rearrangement）。布里斯洛中間體之催化反應可能因其碳氮鍵斷裂而中止，形成碎片。我們證實其反應中可以形成自由基，亦可形成離子。反應趨向之路徑與布里斯洛中間體之羥基的質子化型態有關。碎片化反應亦可視為轉酮醇酶（tran

sketolase）中之噻胺（thiamin）催化反應中之副反應；此研究證實轉酮醇酶透過限制布里斯洛中間體之結構與質子化型態，使其碳氮鍵斷裂需更高之反應能量，進而抑制此副反應。

為了解決second form of be的問題，作者Hamada, Megumi 這樣論述：

An increasingly popular approach to second and foreign language education, this book focuses on incidental learning: how students learn words from reading. Despite its popularity, some researchers have questioned this theory that students can learn new words by inferring meanings based on a text the

y are reading. So, why does the incidental method not work for some students? What are the conditions for naturalistic learning to occur? What do students need to be able to do while reading in order to learn words successfully? Tackling these questions head-on, this book provides researchers and ed

ucators with a more specific account of the processes behind the seemingly naturalistic method. Clarifying the connection between reading and word learning processes, Megumi Hamada proposes a new model, the Cognitive Model of Word-Meaning Inference, to describe how we obtain and use word-form and co

ntextual information for learning words and the pedagogical applications of this. A significant new contribution to research in the field, Learning Words from Reading provides a cognitive perspective on how students learn new words from reading in a second or foreign language. Megumi Hamada is Pro

fessor of English in the TESOL and Linguistics programs at Ball State University, USA.

調控高分子給體二維共軛側鏈與設計共軛中心核與pi-架橋小分子受體結構與性質之系統性研究

為了解決second form of be的問題，作者陳重豪 這樣論述：

此研究中，我們通過引入具有（苯並二噻吩）-（噻吩）（噻吩）-四氫苯並惡二唑（BDTTBO）主鏈的新型供體-受體（D/A）共軛聚合物製備了用於有機光伏（OPV）的三元共混物。在BDTTBO單體中BDT供體單元上修飾不同的共軛側鏈聯噻吩 (BT)、苯並噻吩 (BzT) 和噻吩並噻吩 (TT)（記為 BDTTBO-BT、BDTTBO-BzT 和 BDTTBO-TT）。然後，我們將 BDTTBO-BT 或 BDTTBO-BzT 或 BDTTBO-TT 與聚（苯並二噻吩-氟噻吩並噻吩）（PTB7-TH）結合起來，以擴大太陽光譜的吸收並調整活性層中 PTB7-TH 和富勒烯的分子堆積，從而增加短路電流密

度。我們發現參入10%的BDTTBO-BT高分子以形成 PTB7-TH：BDTTBO-BT：PC71BM 形成三元共混物元件活性層可以將太陽能元件的功率轉換效率從 PTB7-TH 的二元共混物元件 9.0% 提高到 10.4%： PC71BM 轉換效率相對增長超過 15%。於第二部分，我們比較在BDTTBO單體中BDT供體單元上修飾硫原子或氯原子 取代和同時修飾硫原子和氯原子取代的側鏈聚合物供體與小分子受體光伏的功率轉換效率 (PCE) 的實驗結果與由監督產生的預測 PCE。使用隨機森林算法的機器學習 (ML) 模型。我們發現 ML 可以解釋原子變化的聚合物側鏈結構中的結構差異，因此對二元共混

系統中的 PCE 趨勢給出了合理的預測，提供了系統中的形態差異，例如分子堆積和取向被最小化。因此，活性層中分子取向和堆積導致的結構差異顯著影響 PCE 的預測值和實驗值之間的差異。我們通過改變其原始聚合物聚[苯並二噻吩-噻吩-苯並惡二唑] (PBDTTBO) 的側鏈結構合成了三種新的聚合物供體。同時修飾硫原子和氯原子取代的側鏈結構用於改變聚合物供體的相對取向和表面能，從而改變活性層的形態。 BDTSCl-TBO:IT-4F 器件的最高功率轉換效率 (PCE) 為 11.7%，與使用基於隨機森林算法的機器學習預測的 11.8% 的 PCE 一致。這項研究不僅提供了對新聚合物供體光伏性能的深入了解

，而且還提出了未明確納入機器學習算法的形態（堆積取向和表面能）的可能影響。於第三部分，為了理解下一代材料化學結構的設計規則提高有機光伏（OPV）性能。特別是在小分子受體的化學結構不僅決定了其互補光吸收的程度，還決定了與聚合物供體結合時本體異質結 (BHJ) 活性層的形態。通過正確選擇受體實現優化的OPV 元件性能。在本研究中，我們選擇了四種具有不同共軛核心的小分子受體——稠環核心茚二噻吩、二噻吩並茚並茚二噻吩（IDTT）、具有氧烷基-苯基取代的IDTT稠環核心、二噻吩並噻吩-吡咯並苯並噻二唑結構相同的端基，標記為 ID-4Cl、IT-4Cl、m-ITIC-OR-4Cl 和 Y7，與寬能帶高分子

PTQ10 形成二共混物元件。我們發現基於 Y7 受體的器件在所有二元混合物器件中表現出最好的光伏性能，功率轉換效率 (PCE) 達到 14.5%，與具有 10.0% 的 PCE 的 ID-4Cl 受體相比，可以提高 45%主要歸因於短路電流密度 (JSC) 和填充因子 (FF) 的增強，這是由於熔環核心區域中共軛和對稱梯型的增加，提供了更廣泛的光吸收，誘導面朝向並減小域尺寸。該研究揭示了核心結構單元在影響有源層形態和器件性能方面的重要性，並為設計新材料和優化器件提供了指導，這將有助於有機光伏技術的發展。最後，我們比較了具有 AD-A´-DA 結構的合成小分子受體——其中 A、A´ 和 D 分

別代表端基、核心和 π 價橋單元—它們與有機光伏聚合物 PM6 形成二共混物元件。 增加核苝四羧酸二亞胺 (PDI) 單元的數量並將它們與噻吩並噻吩 (TT) 或二噻吩吡咯 (DTP) π 橋單元共軛增強了分子內電荷轉移 (ICT) 並增加了有效共軛，從而改善了光吸收和分子包裝。 hPDI-DTP-IC2F的吸收係數具有最高值（8 X 104 cm-1），因為它具有最大程度的 ICT，遠大於 PDI-TT-IC2F、hPDI-TT-IC2F和 PDI-DTP-IC2F。 PM6:hPDI-DTP-IC2F 器件提供了 11.6% 的最高功率轉換效率 (PCE)；該值是 PM6:PDI-DTP-

IC2F (4.8%) 設備的兩倍多。從一個 PDI 核心到兩個 PDI 核心案例的器件 PCE 的大幅增加可歸因於兩個 PDI 核心案例具有 (i) 更強的 ICT，(ii) 正面分子堆積，提供更高的和更平衡的載波遷移率和 (iii) 比單 PDI 情況下的能量損失更小。因此，越來越多的 PDI 單元與適當的髮色團共軛以增強小分子受體中的 ICT 可以成為提高有機光伏效率的有效方法
