Microanalysis of Atmospheric Particles: Techniques and Applications in Climate Change and Air Quality

為了解決Atomic的問題，作者Conny, Joseph M. 這樣論述：

The effects of atmospheric aerosols on climate and air quality are very timely. Due to advances in instrumentation as well as the need to study the complexity of atmospheric interactions, aerosol analysis has progressed from primarily the analysis of bulk material to the analysis of individual pa

rticles. Microanalysis of Atmospheric Particles: Climate Change and Air Quality - presents the latest developments in the various techniques for particles captured in place and how those techniques are used to explain the complexity of aerosols and their effects on climate and air quality. Technique

s involve scanning electron microscopy, computer-controlled SEM for particle population analysis, transmission electron microscopy, and scanning TEM, energy dispersive x-ray spectrometry associated with electron microscopy, energy-filtering and electron energy loss spectrometry associated with TEM,

focused ion-beam scanning electron microscopy and FIB tomography, micro-Raman spectroscopy, scanning transmission x-ray microscopy and near-edge x-ray absorption fine structure, and atomic force microscopy.Volume highlights include: - Presents the state-of-the art in analyzing individual atmospheric

particles by a variety of microanalytical techniques- Focuses on aerosols in ambient air and their climate or air quality impacts or whose precursor emissions directly impact climate and air quality- Discusses the use of microanalysis in studies of soot, mineral dust, organic aerosols, bioaerosols,

heterogeneous reactions and particle aging, ice nucleation, and particle hygroscopicityMicroanalysis of Atmospheric Particles: Climate Change and Air Quality is a valuable resource for graduate students, researchers and professionals in the fields of atmospheric sciences, geosciences, earth science

s, environmental sciences, mineralogy, electron microscopy, and climate change studies.

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Atomic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。

n imaging and plasmonics, applied in nanoscience research.

鎢微探針的電化學製程特性分析與模擬

為了解決Atomic的問題，作者林佳勳 這樣論述：

鎢本身硬度高、使用壽命長具有良好導電性與耐腐蝕等優點，在半導體產業是不可或缺的角色，由於鎢本身材質太硬又脆導致在傳統產業加工時不容易切削，不僅會傷及工件也會造成加工表面品質不良，用電化學加工的方式去進行鎢棒的製程反而會讓加工表面光潔度高、 品質穩定等優點，針對產業的需求鎢針屬於一種消耗品需要去大量生產，而半導體產業追求微小奈米化，讓許多探討探針相關的研究人員都朝向奈米探針製程去做改良，但是在模擬方面的探針研究相對來說少很多，本文應用COMSOL軟體建構鎢針製程的模型，並用COMSOL Multiphysics進行多重物理有限元素分析，針對鎢針製程的參數、幾何、電流分佈、電極反應軟體建立一套數

值模型方法模擬探針的製程，日後就不需要完全依賴實驗去生產探針，可以先藉由給定的參數去計算模擬來得知結果，對於模擬分析我們可以減少實驗的次數並節省下時間並對業者提供鎢針模擬製程之參考。
