Seaweed Biotechnology: Biodiversity and Biotechnology of Seaweeds and Their Applications

為了解決Raw material的問題，作者 這樣論述：

Seaweeds are known for their rich bioactive compounds, which promote health in human beings and are good for the ecosystem as well. They are also natural resources that are a major source of raw material for different industries. There are still undiscovered and unexploited compounds synthesized

by seaweeds that may have potential applications in the pharmaceutical, nutraceutical, food, and cosmetics industries.This book serves as a comprehensive knowledge source for the predominant roles of seaweeds in various sectors, particularly in the areas of health, environment, and agriculture. It e

xplores the diverse biodiversity aspects of seaweeds and their derivatives. The book critically reviews the present industrial challenges to investigate the novel compounds synthesized by seaweeds and their unique characteristics and benefits.The volume covers the various biodiversity attributes of

tropical seaweeds, their cultivation and bioactive compounds, and the diverse agricultural and biomedical applications of new seaweed derivatives. The authors also discuss the current challenges, emerging markets, and latest developments in extracting the useful biomolecules from seaweeds as well as

the role of seaweeds in food security and environmental mitigation.With chapters written by experts and professionals in the field, this volume, Seaweed Biotechnology: Biodiversity and Biotechnology of Seaweeds and Their Applications, provides a deep understanding of the biodiversity of seaweeds ar

ound the world and their industrial, biomedical, and environmental applications.

利用焙燒暨酸浸法從廢棄LED晶粒中回收鎵金屬資源

為了解決Raw material的問題，作者吳德懷 這樣論述：

LED是發光二極體(Light Emitting Diode)的簡稱。由於LED燈具有節能、無汞等特性，在照明市場之需求日益增加，LED在許多領域已經取代了傳統光源(白熾燈、螢光燈等)。LED燈之高效率白光照明主要是由LED晶粒中氮化鎵(GaN)半導體所產生。隨著LED市場的擴大，未來將產生大量的LED廢棄物。因此，回收廢棄LED中所含的鎵金屬資源對於資源的可持續利用和環境保護都具有重要意義。本研究以廢棄LED燈珠為對象，利用焙燒與酸浸法從其LED晶粒中回收鎵金屬資源，主要包括三個部分：化學組成分析、氟化鈉焙燒處理與酸溶浸漬等。探討各項實驗因子包括焙燒溫度、焙燒時間、礦鹼比、酸浸漬種類及濃度

、浸漬時間、及浸漬固液比等，對於鎵金屬浸漬率之影響，並與各文獻方法所得到的鎵金屬浸漬效果進行比較。研究結果顯示，LED晶粒中含有鎵5.21 wt.%，氟化鈉焙燒暨酸溶浸漬之最佳條件為焙燒溫度900 ℃、焙燒時間3hr、礦鹼比1:6.95、鹽酸浸漬濃度0.5 M、浸漬溫度25 ℃、浸漬時間10mins、固液比2.86 g/L，鎵金屬浸漬率為98.4%。與各文獻方法相比較，本方法可於相對低溫且常壓下獲得較高之鎵金屬浸漬效果。

Materials Recycling Handbook

為了解決Raw material的問題，作者 這樣論述：

The process of conversion of waste materials into new ones is known as recycling. Materials recycling are used to reduce the usage of fresh raw materials and lower greenhouse gas emissions. It is considered an alternative to conventional disposal of waste. It is an important component in modern w

aste reduction. It is used to recycle a variety of materials such as metal, plastic, cardboard, batteries, electronics and paper. Depending upon the material, different techniques are used for its recycling. The field is mainly helpful in producing a fresh supply of the same material that is recycle

d. Materials recycling is an upcoming field of science that has undergone rapid development over the past few decades. The book unfolds the innovative aspects of materials recycling which will be crucial for the understanding of the subject matter. It aims to serve as a resource guide for students a

nd experts alike and contribute to the growth of the discipline.

開發米與幾丁質減積製程並提升酵素降解速率

為了解決Raw material的問題，作者陳衍齊 這樣論述：

米與幾丁質經酵素降解可得葡萄糖及N-Acetyglucosamine(GlcNAc)，在醫療技術上及營養層面皆展現非比尋常的價值，而粒子微小化可幫助其降解速率增加。本研究將米與幾丁質兩種生質原料經由兩階段磨碎，得到所需粒徑尺寸，並驗證其酵素反應的提升。於不同的機台進行物料尺寸的微小化時，物料的物化特性或是機台本身的參數設定都會影響機台將物料尺寸微小化的效率。於第一階段乾式切削時，由實驗設計及反應曲面法求得米在含水率 1.2 %、切削轉速17918 rpm及切削時間3 min時為最佳化操作參數；幾丁質在含水率5.5 %、切削轉速17837 rpm及切削時間6.4 min時為最佳操作參數。於第二

階段濕式研磨時，第一段以研磨轉速1400 rpm、研磨間距50 µm 及研磨時間1.5 hr，第二段以研磨轉速1400 rpm、研磨間距30 µm 及研磨時間4 hr 為最佳操參數，其平均粒徑達5.1 µm ；幾丁質於研磨轉速1400 rpm、研磨間距5 µm及研磨時間12 hr時為最佳操作參數，其平均粒徑達22.1 µm。另外於酵素反應下檢測反應速率變化，由Michaelis-Menten動力學方程式得知，在最佳操作參數下觀察米的粉體研磨情形，V_max提升11.5倍，於長時間反應下轉化率提升36倍；在最佳操作參數下觀察幾丁質粉體研磨情形，V_max提升26.1倍，於長時間反應下轉化率提升3

2.2倍。
