주제: 세포막을 통한 물질이동
부제: 세포막을 통한 물질의 이동 현상을 이해하고, 세포의 생리적인 변화를 관찰한다.
Ⅰ. 이론 및 원리
1. 세포(cell)
생명의 기본 단위인 세포(cell)는 생존에 필요한 구조와 분자 구성물을 포함하고 있으며 이 안에서 세포는 양분을 취하고 에너
What is Amorphous metal?
Polycrystalline grains of varying shapes and sizes
Misaligned planes of atoms slip past each other easily, absorbing energy and allowing dislocations to move, making deformation permanent.
Grain boundaries represent weak spots
Also called Metallic glasses or glassy metals
Cooled faster than atoms can rearrange into a crystal.
Dislocation movement obstructed s
Dialysis
What is dialysis?
Dialysis is a membrane process where solutes (MW~<100 Da) diffuse from one side of the membrane (feed side) to the other (dialysate or permeate side) according to their concentration gradient. First application in the 70’s.
General Principles
Separation between solutes is obtained as a result of differences in diffusion rates.
These are arising from differe
