[A. wood faces]

1. wood block is roughly wash with water or ethanol to remove the dust

2. the washed block was oven or air-dried

3. the sample was observed by the digital micro scope (KEYENCE)

https://www.keyence.co.jp/products/microscope/

4. wood has 3 faces of transverse, radial, and tangential section. So, you have to observe from the 3 angles of the transverse  (TR, 柾目), the radial  (R, 木口), and the tangential section (TA, 板目).

[A. homework]

1. Take three pictures at the lower magnification, which tell us the wood faces in the transverse (TR, 柾目), the radial (R, 木口), and the tangential section (TA, 板目).

2. You prepare the word file with the pictures and their directions. When you prepare it, don’t forget to reduce the file size.

[B. Microstructures]

1. use the same sample and microscope.

2. When you zoom up from 3 angles, you will find some typical wood structures as the below.

[B. homework]

1. At the higher manification, take three pictures from the each angles, which show some typical wood structures, such as the tracheids (仮道管), vessels (道管), pits (壁孔), ray (放射組織).

2. Search the name of your found typical structure, asking the google! Let’s try !!

3. Prepare the word file with the pictures and their name.

 

[C. pulp & nanostructures]

under constructions
