task currently important.
Regulation of nanoparticles.
Size : 10~100nm (EPR effect)
Coating PEG polymer
Why nanoparticles?
1) It can deliver a larger quantity of drugs with better safety.
2) Easy to attach targeting ligands.
3) It is enough size to deliver multi-drugs.
4) Can regulate releasing of drug particles.
5) Can avoid multidrug resistance through cell-surface protein pump.
3. Requirements of EUV resist
EUV is highly absorbed by all materials, even EUV optical components inside the lithography tool are susceptible to damage, mainly manifest as observable ablation. Such damage that is associated with the high-energy process of generating EUV radiation is a new concern specific to EUV lithography .
EUVL's shorter wavelength also increases flare, resulting in less
2. Impacts of I-Phone's appearance on the Korean domestic mobile phone market
iPhone opened up a new era of domestic smartphone market by expanding the market for the smartphone.
1) Immediately after iPhone was introduced into the market, the sales of smartphone increased from below 3% to 18.9%. So smartphones account for a huge portion of domestic mobile phone market. It means that iPhone re
resistance that prevent corrosion of interior reinforcing rod because is alkalinity is security
3) have excellent modeling.
4) ability that have high hardness and stand in shock of pedestrian or machine operation etc. is big.
On the other hand, shortcoming is
1) withstand to Apchukryeok, force that press, but is weak in tensility, force that pull.
2) because weight is high than strength,
to manufacture ammunition after Germany's nitrate supplies had been cut off.
Commercial ammonia synthesis takes place in large steel reactors that are designed to withstand very high pressures (up to one thousand atmospheres) and high temperatures (about 700°C or 1300°F). The reactors also resist attack by hydrogen gases which can corrode many metals, especially at high temperature and press
