透射電子顯微鏡(Transmission-electron-microscopy,-TEM)
透射電鏡具有很高的空間分辯能力,特別適合納米粉體材料的分析。其特點是樣品使用量少,不僅可以獲得樣品的形貌,顆粒大小,分布以還可以獲得特定區域的元素組成及物相結構信息。透射電鏡比較適合納米粉體樣品的形貌分析,但顆粒大小應小于300nm,否則電子束就不能透過了。對塊體樣品的分析,透射電鏡一般需要對樣品進
Transmission-Electron-Microscope-(TEM)
所謂TEM,就是一個放大鏡疊加了一臺照相機。這臺放大鏡的放大倍數比較高,可高達一百萬倍。當然,拋開分辨率談放大倍數都是耍流氓,那么,TEM的分辨率有多高呢?答案是 it depends。一般來說,TEM的分辨率要在1到2個納米,STEM更高,但是STEM得成像技術類似于SEM,但用的不是二次電子。我

SCI論文中怎樣描述TEM結果?樣品有怎樣的形貌
鑒于有同學問我對于SCI論文寫作這個部分的更新計劃,我在這里稍微跟大家說一下。這個部分肯定不僅僅是列出一些常規實驗結果如何描述這么簡單。現在發的這些呢,只是一些基礎準備。在將這些準備工作做完了之后,我們會按照論文的結構,對每個部分進行詳細討論,盡可能把我們這些年學到的有用的東西分享給大家,給大家提供
形貌分析
形貌分析的主要內容是分析材料的幾何形貌,材料的顆粒度,及顆粒度的分布以及形貌微區的成份和物相結構等方面。形貌分析方法主要有:光學顯微鏡(Opticalmicroscopy,OM)、掃描電子顯微鏡(Scanningelectron microscopy, SEM)、透射電子顯微鏡(Transmissi
