specific surface area उदाहरण वाक्य

उदाहरण वाक्य

1. SWNTs have a high theoretical specific surface area of 1315 m 2 / g, while that for MWNTs is lower and is determined by the diameter of the tubes and degree of nesting, compared with a surface area of about 3000 m 2 / g of activated carbons.
2. These minerals tend to form in sheet or plate like structures, with length typically ranging between 10  " 7 m and 4x10  " 6 m and thickness typically ranging between 10  " 9 m and 2x10  " 6 m, and they have a relatively large specific surface area.
3. Activated carbon is an extremely porous form of carbon with a high specific surface area  a common approximation is that 1 gram ( 0.035 oz ) ( a pencil-eraser-sized amount ) has a surface area of roughly  about the size of 4 to 12 tennis courts.
4. Recently, Ruoff and his group reported on a new carbon, potentially having regions of  negative curvature carbon ( NCC ) with a remarkably high specific surface area of 3100 m?g  " 1, and atom-thick carbon sp 2-bonded walls that define pores varying in diameter from about 0.6 to 5 nm.
