Seriousness of Climate Change
-Temperatures around the world have increased -> melting glaciers and rising sea levels
-Change of habitats, wildlife, cultures, artifacts and the life of humans.
-changes in ecosystem, rainfall, desertification. -> flood, drought, typhoons, yellow dust, heat wave

리튬이온전지는 음극재, 양극재, 분리막, 전해액 등 4개의 핵심소재로 구성되어 있고, 이 핵심소재들이 반응하여 에너지를 저장하고 방출합니다.
양극재는 전기가 들어오면 리튬이온을 통해 전하를 실어 나르는 역할을 하고, 음극재는 이동해 온 리튬이온과 전하를 저장하였다가 방출하는 역할을 담당

What is the common thing between Coca-cola and Hamburger? We think the common thing is the fact that there would be not much people who do not know about these products.
Almost every time we are revealed to these products, and it is not difficult to see someone eating Hamburger and Coca-cola. And especially, we want to cover about Mcdo
다양한 알루미나 제조 방법
알루미나(Al₂O₃) 제조는 다양한 방법이 있다.
대표적으로,
▶액상합성법:
전구체를 액상의 매체에서 반응시켜 최종 알루미나 분말을 제조하는 방법. Ex) Bayer법, sol-gel법
▶기상합성법:
전구체를 기상에서 열분해시켜 입자를 제조하는 방법.
내열성, 내식

It is this: FORM IS NEVER MORE THAN AN EXTENSION OF CONTENT. (Or so it got phrased by one, R. Creeley, and it makes absolute sense to me, with this possible corollary, that right form, in any given poem, is the only and exclusively possible e
Manipulation of a micro-object by using an optically driven mircroneedle.
Fig 5.(a) Pushing a micro-object with an arm of the microneedle.
Fig 5.(b) Pricking a micro-object with a submicron probe tip of the microneedle.
The probe tip was sufficiently strong to prick the micro-object.
