structure, loose, lubrication, easy absorption of moisture, light and other traits of white powder, so it is also called "white graphite". The expansion coefficient of boron nitride is equivalent to quartz, but its thermal conductivity is ten times that of quartz. It also has good lubricity ...
atomic nucleus in 1911 when he attempted to pass a beam of alpha particles through a thin sheet of gold foil. Rather than passing through the sheet unimpeded, some of the alpha particles bounced back. This showed Rutherford that the previous model for the structure of the atom was not ...
fact that it can take many months, or even years, after a major development project for companies to find out whether they've hit the jackpot or not. One cause of the delay is the intertwined but fragmented structure of the industry: different sectors peak and bottom out at different ...
