1 GPa
Elastic modulus Nanoindentation > 6 GPa
Adhesion Tape pull, modified-edge lift-off Delamination-free
Disavantages
Weakens mechanical properties
Lower thermal conductivity
Narrow pore distribution to ensure dielectric constant is homogeneous and isotropic
Pores need to be closed cells to prevent crack propagation and moisture absorption
Need to add silica to seal surface pores
이러한 관점에서 Pb Solder는 Pb의 매장량이 높고, 결착성이 좋으며 가장 좋은 특성으로는 낮은 융점 때문에 Pb Solder의 사용이 널리 퍼져 있었다. 사실 접합부에 Pb를 사용하는 것은 전도도가 좋기 때문은 아니다. Pb의 전도도는 Cu의 7%밖에 되지 않는다. 그러나 Pb를 사용하게 된 이유는 역시 대량 생산제품의
클라이언트/서버 구조는 시스템의 자원에 접근할 때 두 종류의 구별되는 개체가 관여한다는 사실을 반영한다. 첫번째 개체는 클라이언트로 시스템의 자원에 접근하고자 요청을 보내는 쪽이다. 두번째 개체는 서버로 클라이언트의 요청이 들어올 때만 작동한다. 서버는 자원들을 직접다룰 수 있으며 그
Super-capacitors
EDLC(electrochemical double layer capacitors)
→ store E using ion adsorption
Pseudo-capacitors
→ fast surface redox reactions
→ higher capacitance than EDLC
Redox super-capacitors
electron transfer caused by electrochemical oxidation and reduction of active reagents
between two electrodes with different potentials

I. Introduction
As the world is becoming increasingly interconnected, free trade is rapidly becoming the standard norm on international economics. Korea and China are no exceptions to this trend and are in the early stage of negotiating a free trade agreement (FTA). So why is Korea pursuing to establish free trade with China? From 2004, China has replaced the United States as Korea’s number

properties we wish to have in any drug delivery across the BBB(Blood brain barrier). In this context, owing to their small size, customizable surface, improved solubility, targeted drug delivery and multifunctionality, nanoparticles have emerged as potential drug delivery carriers to tissues throughout the body. Yet passing the BBB is particularly difficult. The proper design of such engineered
