A Study on Taiwan’s Green Building Biodiversity Index

1999年台灣內政部建築研究所推動並實施台灣綠建築評估系統，2003年始 於綠建築評估系統中加入「生物多樣性指標」，後「生物多樣性指標」評估內 容每隔兩年均有修正及調整，是綠建築評估系統九大指標中調整頻率及幅度最 高之指標，可見台灣對「生物多樣性指標」相當重視。至今台灣綠建築「生物 多樣性指標」評估已實施將屆滿十年，本研究認為有必要探討台灣綠建築「生 物多樣性指標」執行現狀，了解實際案例得分之分佈情況，分析實際案例的指 標設計項目得分難易度以及各設計項目之鑑別度。 本研究將2006年至2012年台灣地區設計有「生物多樣性指標」通過綠建築 標章之案件，依各類建築物申...In 1999, the Architecture and Building Research Institute, a leading national research agency in Taiwan under the supervision of the Ministry of the Interior, began to promote and implement the Taiwan Green Building Assessment System (TGBAS). The Biodiversity Index was added into the assessment system in 2003. From then on, the evaluating items of biodiversity index has been constantly revised...学位：建筑学硕士院系专业：建筑与土木工程学院_建筑设计及其理论学号：2522010115456

Total morphosynthesis of biomimetic prismatic-type CaCO3 thin films

我校材料学院姜源副教授，与浙江大学唐睿康教授课题组、德国Konstanz大学Helmut Cölfen教授课题组合作，首次利用全合成手段获得了仿贝类棱柱层结构的碳酸钙薄膜，并实现了仿生薄膜微结构的精准调控，由此获得了优异的力学性能。本研究团队基于生物矿物的空间结构异质性，并参考了传统晶态薄膜材料合成中的液相外延方法，首次设计出了多步仿生矿化路线，在常温液相条件下成功地构筑了利用聚电解质稳定的矿物种子层，并在此基础上利用外延矿化方法构筑了碳酸钙的棱柱层结构。本研究制备的棱柱层薄膜不但与相对应的生物矿物在微结构上具有高度的相似性，同时还具有类似的硬度和杨氏模量。文中提出的基于种子层外延生长的多步矿化路线是获得棱柱层仿生结构的普适方法，也加深了人们对于生物矿化机制的认识。【Abstract】Biomimetic mineralization can lead to advanced crystalline composites with common chemicals under ambient conditions. An exceptional example is biomimetic nacre with its superior fracture toughness. The synthesis of the prismatic layer with stiffness and wear resistance nonetheless remains an elusive goal. Herein, we apply a biomimetic mineralization method to grow prismatic-type CaCO3 thin films, mimicking their biogenic counterparts found in mollusk shells with a three-step pathway: coating a polymer substrate, deposition of a granular transition layer, and mineralization of a prismatic overlayer. The synthetic prismatic overlayers exhibit structural similarity and comparable hardness and Young’s modulus to their biogenic counterparts. Furthermore, employment of a biomacromolecular soluble additive, silk fibroin, in fabrication of the prismatic thin films leads to micro-/nano-textures with enhanced toughness and emerging under-water superoleophobicity. This study highlights the crucial role of the granular transition layer in promoting competition growth of the prismatic layer.Y.J. acknowledges financial support from the National Natural Science Foundation of China (NSFC; 21303144) and Science Foundation of the Fujian Province, China (2014J01207).
