is the most significant measure of federal securities and corporate law since the New Deal legislation of the 1930s. The act was a reaction to a number of major corporate and accounting scandals including those affecting Enron, Tyco International, Adelphia, Peregrine Systems and WorldCom. These scandals, which cost investors billions of dollars when the share prices of affected companies collaps
this, we can know that axial impeller is not suitable. Also, because of wide width of tank, it has poor mixing.
Second, there is a problem with chemicals. PAC is injected with Cl2, so activation of Cl2 must be restricted.
Also, using alum may cause settling.
Alum lowered pH in localized area. To overcome this problem, we need more alkali materials and it means lots of cost.
1. Cleaning
- For elimination particle
2. Deposition
- Formation some material layer on the substrate
3. Photolithography
- Formation some pattern
4. Etching
- Elimination substrate or PR layer
Material to be evaporated is heated to
increase vapor pressure

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
As is well known that GE Edison founded the company from a small electrical current that advanced technology and services, and capital on the basis of the world 's energy, environment, health, water, etc. to solve the challenges our leadership is a global company. Most of all, GE has a long history of counter trade, using commodities in return for payment and also a special department for it.

● Definition of plasma
Plasma is one of the four fundamental states of matter, along with solid, liquid, and gas. It is an ionized gas consisting of a collection of charged particles, including ions, electrons, and neutral atoms or molecules. Plasma can be found naturally in the universe in the form of stars, lightning, and auroras, but it can also be artificially created and controlled for

What is soft-lithography?
So, an alternative and non-photolithographic method that we call soft lithography was developed. Because this method uses a patterned elastomer(e.g. PDMS(Poly DiMethyl Siloxane)) as the stamp, mold, or mask to generate micro-patterns and microstructures, it was titled as 'soft' lithography. As compared with photo-lithography, soft lithography has many kinds of strength.
