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
가-2. DIMM
현재 인텔 펜티엄이나 모토로라의 파워PC 등과 같은 프로세서에서 64비트 데이터 버스에 알맞게 사용하기 위해서는 72핀 SIMM을 쌍으로 인스톨해야 하며, 이로 인해 모듈이 차지하는 크기가 커졌다. 그러나 소수의 컴퓨터만이 대용량 메모리 모듈을 지원할 수 있었기 때문에 물리적인 크기의 변

Introduction
Nowadays, the method of chemotherapy + radiation is widely used because it is more effective for cancer cells than normal cells.
However, patient’s quality of life is directly related to the targeting ability of treatment, so that method has some side effects.
So finding less toxic agents and choosing a precise delivery system is a task currently important.
Regulation of nan

Action on the molecule themselves
Or through “handles” such as glass beads, polystyrene beads or metallic particles attached to molecules.
exerts forces on objects through the transfer of momentum from the fluid to the object
Advatages
Liquids surrounding the tethered macromolecule can be easily replaced.
Flow can be used to introduce new beads or biomolecules
