簡介：希瓦氏菌MR1是一種非常重要的模式產電細菌，它具有胞外電子傳遞的功能，能夠將呼吸鏈產生的電子傳遞到環境中的固態鐵等電子受體上，因此這種細菌在微生物燃料電池體系中得到了廣泛的應用。人們對希瓦氏菌MR1的產電代謝通路已經做了很多研究，目前主流認為有兩條主要的代謝路徑在鐵氧代謝中，CYMA將電子通過延胡索酸還原酶FCCA傳遞給金屬還原蛋白MTRA，或者將電子直接傳遞給MTRA，并通過MTRA、B、C一系列金屬還原蛋白將電子從細胞質內通過細胞膜表面的脂質體傳遞到細胞外膜而在鐵硫代謝中，傳遞到細胞質中的電子通過PSRA、PSRB、PSRC等蛋白傳遞到細胞的外表面。當電子被傳遞到細胞的外表面之后，希瓦氏菌MR1通過細胞色素C介導、微生物納米導線等機制將電子進一步傳遞到胞外的電子受體上。人們通過研究發現，一定條件下細菌的共培養可以提高微生物燃料電池裝置的產電效率，因而共培養過程中的產電機制也開始為研究人員所重視。然而，共培養對希瓦氏菌MR1代謝路徑的影響還沒有人做過詳細研究。本論文以希瓦氏菌MR1為研究目標，構建了雙室的微生物燃料電池MFC體系，用相關的電化學分析方法和16SRNA基因測序等分析手段，討論了不同培養環境下MFC裝置的電化學特征的變化，研究了菌群中希瓦氏菌與其他菌的相互作用利用REALTIMEPCR技術對MTRA、MTRB、MTRC、OMCA等與希瓦氏菌MR1產電代謝通路有關的基因進行了相對定量分析，研究了陽極室內雙菌株共培養和菌群共培養過程中希瓦氏菌產電通路的變化規律。我們對每個MFC裝置至少經過3個工作周期的觀測和記錄，繪制不同體系下MFC裝置的極化曲線、循環伏安曲線（CV曲線）、開路電壓曲線、功率密度曲線等，根據獲得的數據對不同體系下MFC裝置的內阻、電容量、開路電壓、工作功率密度、最大理論產電效率、庫倫效率等電化學數據進行表征。數據證明，混合菌培養確實能夠提高產電效率，優化MFC體系的電化學性能。同時，混合菌培養有助于MFC裝置內阻的降低和庫倫效率的提高。我們在希瓦氏菌MR1MFC裝置的陽極電極上監測到了MTRA、MTRB、MTRC、OMCA基因隨著培養時間增長，表達量均有不同程度的提高，這說明這些基因與MFC裝置中希瓦氏菌的電子代謝通路有關在雙菌株共培養MFC體系中，OMCA基因的相對表達量有了顯著的提高，這可能是雙菌培養在電子從胞外轉移到電子受體的過程起到了一定作用而在加入檸檬酸鐵的菌群共培養MFC體系中，MTRA、MTRB、MTRC基因的相對表達量均有顯著的提高，一方面，這說明了鐵氧化物和MTRA、MTRB、MTRC基因的表達密切相關，另一方面，這說明多培養MFC體系中希瓦氏菌的電子代謝通路確實發生了變化，這些變化正向促進了希瓦氏菌在MFC體系中的電子傳遞，從而對混合菌株在土環境中的電子傳遞造成了影響。

簡介：隨著智能化信息時代的到來，大規模集成電路也進入高速發展階段，然而晶體管器件尺寸不斷縮小即將達到極限，集成度不斷升高導致芯片發熱等副作用都成為限制集成電路的發展的阻礙，因此新型電路元器件的發現和應用變得至關重要。此時憶阻器進入人們的視野，它具有結構簡單、尺寸小、功耗低、易于集成、與CMOS兼容等一系列的優勢，因此迅速成為半導體和集成電路領域研究人員關注的重點。突觸是神經網絡的重要組成部分，也是人工神經網絡模擬的關鍵，傳統突觸的模擬采用晶體管器件，受限于晶體管尺寸和功能，密度遠低于生物神經網絡中突觸的密度。由于憶阻器的尺存達納米級，并且憶阻器可以像突觸一樣工作，是目前已知的功能與生物突觸非常接近的器件，提供了構筑模擬神經網絡的基礎?；趹涀杵鞯膬瀯?，憶阻器替代傳統的晶體管實現生物突觸模擬，使得人工神經網絡中突觸密度進一步向生物神經網絡靠攏，進而可以實現低功耗、高集成度的神經網絡模擬。本論文從憶阻器基本結構、阻變機制和模型三個方面對憶阻器進行了分析，深入認識憶阻器作為第四種基本電路元件對整個電子電路行業發展帶來的重要作用。分析了憶阻器在非易失性存儲、數字模擬電路、神經網絡等領域的應用，給出了一種基于憶阻器的靜電保護電路。充分認識生物突觸結構、工作原理和重要特性，將憶阻器應用于模擬突觸，并以權值調整電路實現突觸的脈沖時間依賴可塑性學習規則。在實現憶阻器模擬突觸基礎上進一步模擬由突觸和神經元構成的神經網絡。通過三個神經元和兩個突觸的結構模擬巴甫洛夫的狗的模型，以實現聯想記憶功能。使用KEITHLEY4200SCS半導體參數測試儀表征NIO憶阻器和HFO2憶阻器的阻變特性，設計突觸權值調整電路和聯想記憶電路的PCB級電路，并將NIO憶阻器連接在電路中，仿真和測試結果證明電路完成了所需要的功能。本文證實了突觸和神經網絡的模擬可以通過基于憶阻器的硬件電路來實現，而不僅僅停留在仿真階段，為構建更復雜神經網絡提供了新思路，有望在不久的將來進一步實現超高密度的神經網絡。
