Small angle scattering glasses

Warren, Bertram Eugene (1902-1991 at M.I.T. 1930-1976) is known for his textbook on X-ray diffraction and his studies of the structure of glass and carbon black. These began small-angle scattering research into nonperiodic and nearly periodic structures. 

These results confirm the earlier conclusion [18] that at 26 5mol% P2O5 there is a stable immiscibility in Te02 P205 glasses, combination of SANS and TOP methods is very powerful. The use of pulsed neutron sources and position sensitive detectors permits the construction of a TOP apparatus at A / >0.1 with performances, compatible to or better than the best x-ray small angle scattering instruments.

Based on such results of microporosity. X-ray diffraction and small angle scattering evaluation as well as on density measurements, and finally stimulated by ROLAND s carbon fibre model (26) a 2-dimensional model for glasslike carbon was derived by us as shown in fig. 8, left hand side (18). Simultaneously, by other research groups, the first transmission electron microscopic pictures of glass like carbons (19) confirmed this assumed structure (fig.8, right hand side).
