그림 Cu 방열판
알루미늄은 밀도가 낮고(2.7g/cm3) 열전도도가 좋아 방열 재료로 사용되기에 유리하며, 실제로도 흔히 사용되는 금속원소다. 순수 알루미늄보다는 알루미늄 합금이 일반적으로 사용되며, 열전도도가 크지만(229 W/m‧K) 가공성이 좋지 않
proteins, but there are (as of July 2011) no known structures of any OR. There is a highly conserved sequence in roughly three quarters of all ORs that is a tripodal metal ion binding site, and Suslick has proposed that the ORs are in fact metalloproteins (mostly likely with zinc, copper and possibly manganese ions) that serve as a Lewis Acid site for binding of many odorant molecules.
Nano fiber flooring’s safety
Flooring fulfils the necessary conditions
1. check whether an volatile organic compound emit or not
2. check whether an heavy metal compound emit or not
For example, formaldehyde, cadmium mercury
