Theory
In general, preparation methods for nanoparticles make use of capping agents, such as surfactants, polymers or biomaterial, in order to confine the growth. Occasionally, the selective or preferential adsorption of capping agents onto particular crystallograp- hic facets during the growth stage permits diverse shapes to be produced, for example triangles, hexagons, disks, rods and multi

of the reported procedures for rod formation, seedmediated growth has been by far the most efficient and popular approach. The role played by the seed particle is also critical. Furthermore, the presence of small amounts or silver nitrate during the synthesis has a dramatic effect on the final shape and crystalline structure if the particles. Citrate-capped gold nanoparticle, prepare
Prepare a cause-and effect or fishbone diagram for a problem such as "Why customers have long waits for coffee." Use Figure as a guide.

Alkaline lysis method
- 세포의 cell wall과 cell membrane을 부수고 DNA만을 분리하는 방법
- Chromosomal DNA 와 plasmid의 고유한 형태 구조 차이를 이용 !
; Chromosomal DNA - 상대적으로 size가 크고, double heilx
Plasmid - size가 작고, supercoiled 형태 -> pH에 변화에 의한 변성↓

prepared on the ZnO pre-sputtered glass substrate using RF magnetron sputtering system. The PureZnO target was made from high purity ZnO powder (99.99 %) . The MZO/GZO targets were made from high purity ZnO powder (99.99 %) doped with the desired amount of high purity MgO, Ga2O3, powder (99.99 %), respectively. Prior to the deposition, the glass substrates were cleaned using the typical method, s
1. There is nothing new about man’s need to preserve food for storage or convenience of preparation. Sun-drying, salting, pickling and smoking are methods which have been used for centuries and are still being used today. Recent advances in technology have made it possible to preserve food by decreasing the risk of microbiological spoilage with less loss of taste, texture and nutritive value.

those few who are born trainers are gained from effective training from companies; their efficiency grows and improves significantly as a result. While we analyze various training methods and their benefits with given examples, this report would provide with an insight of two types of broad training methods of company training strategies which are on-the-job trainings and off-the-job trainings.
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
